Billy Laws cce605d5e0 PoolBufferWithTimedRetirement: Unclaim in dtor
Buffers are tied to the lifetime of their owned flag, and as that
is a member of PoolBufferWithTimedRetirement we must always unclaim here.

Avoids the need to manually remember this quirk (which was forgot for the
temporary compilation buffer in JIT.cpp) at every use-site.

Fix: wrong magic value in fpstate.
2025-07-06 17:07:31 -07:00
Changwei Miao 1fe17d55d9 Fix: wrong magic value in fpstate.
FEX should only set fpx_sw_bytes.magic1 with FP_XSTATE_MAGIC when
avx is enabled. Otherwise it may cause segfault in ntdll::save_context,
which requires access to extended xstate info if magic1 equals FP_XSTATE_MAGIC.

Ryan Houdek ead73371d9 EmulatedFiles: Emulate current_clocksource
WINE uses this to determine TSC frequency and because it doesn't say
`tsc` on ARM devices, it was ignoring TSC and instead using CPU maximum
frequency.

This was causing Horizon to think the TSC ran at whatever the max
frequency of a core was  (1.8Ghz to 2.6Ghz depending?) This was causing
all of Horizon Zero Dawn's physics to run at slower than real time
speeds because our 1Ghz (on Orion) TSC is significantly lower than the
max clock speeds of the cores.

This is still a bug in Wine that it is using the maximum CPU clock speed
in the case of current_clocksource not being TSC, but that's a battle
for a different time.

Ryan Houdek 6ebbd91245 JIT: Optimize x87 FSINCOS
Turns out Bayonetta hammers SINCOS, our splitting the operation is
actually harming the performance of games that heavily use FSINCOS. We
instead can actually combine the operation which improves performance.
Not enough to get the game running full speed consistently on my Radxa,
but good numbers in my microbenchmark.

Improvement 64-bit: 1.75x

```

Only a minor improvement at 80-bit precision since cephes doesn't provide a combined sincos operation, but the f64 implementation is significantly improved, allowing 75% more operations per second.

Disabled in the simulator because we can't easily support pairs of
vector registers being returned.

Alyssa Rosenzweig 360d8c629e RegisterAllocationPass: optimize cpuid
for constant function where we don't have a leaf. this isn't fully general but
we can't do better without a more general post-RA optimizer. i'm not inclined to
do that unless/until we get hot blocks demonstrating its value (that we can
compare against the JIT time hit of the heavier-duty optimizer.)

however this special case we can (and should) optimize for now.

Tony Wasserka c1842a6167 Build: Add nix-based helpers to manage toolchains for ARM64EC/WOW64
The cmake_configure_woa*.sh scripts will automatically install any required
cross-toolchains required to enable either ARM64EC or WOW64 builds of FEX,
and it will initialize the current build folder appropriately.

For advanced uses, a shell can be opened by running `nix-shell WineOnArm/shell.nix`,
which will make the toolchain available via environment variables. This also
generates a meson crossfile for building VKD3D or vkd3d-proton.

Ryan Houdek 7ed9bea16b Linux: Implement enough of ptrace to allow Ubisoft launcher
Wine does some minimal attaching, peeking, poking, and detaching to have
a different process inspect another's TEB region. Ubisoft's launcher
does this to check if a debugger is attached and rejects it in the case
that it is.

While this implementation isn't all-encompassing, it is good enough for
this family of games.

Ryan Houdek f6b4c76d76 InstcountCI: Adds tests for instructions discovered by #4597
Apparently I completely missed that cpuid, xgetbv, syscall,
l{u,}{div,rem} were failing to hit their optimized cases for inlining
and avoiding 128-bit software divide.

The divisions are a clear performance regression for 64-bit applications
since that is the only real way to do a 64-bit division on x86, I added
those specifically because it sped up games.

CPUID depends heavily on the game, since some games use that as a
serialization instruction fairly heavily.

XGETBV is trivial since it matches behaviour of CPUID (and is basically
an extension of it).

Syscall inlining can save a decent amount of time, again heavily depends
on game.

Adds multi-inst tests for all of these situations so that once it gets
fixed (Apparently broken once RCLSE got stripped out), we can see that
they keep working. Obviously tests couldn't have existed in instcountCI
before since we didn't support multi-instruction tests.

This is changes the interface of CodeBuffer to that of a partially persistent

- Exactly one CodeBuffer is now designated as "active", which means data can
  be *appended* to it
- Lossy modifications to the active CodeBuffer will not invalidate any data
  in use by other threads, which enables save sharing across threads
- Instead, such lossy modifications trigger a new "version" of the data in
  the modifying thread. Old versions of the CodeBuffer persist as read-only
  data for use by the other threads.
- The other threads can update their version of the CodeBuffer. This will
  decrease the reference count and eventually trigger deallocation of the
  old version

Ryan Houdek ad132267ec Linux/SMCTracking: Fixes nasty race condition causing invalid memory tracking
This has been a bug that we have technically lived with ever since SMC
tracking was introduced. The problem boils down to the fact that memory
management syscalls from multiple threads can race our SMC tracking.

This was only uncovered due to recent changes in the Steam client where
downloading games has more aggressively started reallocating memory.
This causes Steam to oversubscribe the CPU by a small margin, causing
threads to context switch more heavily during memory management.

The strace that finally managed to capture this:
```
41574 munmap(0xba84e000, 724992 <unfinished ...>
<...>
41227 mmap(NULL, 540672, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -3, 0 <unfinished ...>
<...>
41574 <... munmap resumed>)             = 0
<...>
41227 <... mmap resumed>)               = 0xba87b000
```

While FEX's tracking linearly was:
```
mmap, 0xba87b000, 0x84000, 0x3, 0x22, 0xfffffffd, 0x0
munmap, 0xba84e000, 0xb1000
```

The way munmap and mmap perfectly interleave while getting context switched meant that the kernel's view of munmap then mmap didn't match our view of mmap completing first then munmap happening afterwards.
The kernel/strace is obviously the correct view in this instance.

This all comes down to how these threads are racing the VMA tracking
mutex after the syscall happens and not guaranteeing sequential
consistency that matches the kernel's view.

The only way to correct this sanely is to extend the locking period to
also encompass the syscalls getting executed. This is a bit tricky since
the VMA tracking needs to ensure that the lock is no longer held once
ThreadManager invalidation occurs so a callback to do the syscall
operation is about the only sane approach here. Luckily we now have

Tony Wasserka bdceb4ca89 Async: Don't destruct on self-moves
FEXServer's logger performs such self-moves for the log pipe posix_descriptor
of short-lived clients. This resulted in a double-close previously, which
could interfere with file operations on other threads (typically crashing
FEXServer in effect).

as a simple post-RA peephole. much much easier to do post-RA than pre-RA.

This isn't a post-RA /pass/ in the traditional sense... it's done while
assigning registers to coalesce the passes over the IR, since we pay per-pass
and we can merge the walks over the IR.

Avoid hardcoding the file name. Upstream Clang currently expects the aarch64 variant of
compiler-rt. Changing this to use arm64ec in the file name could be problematic in the future,
if the MinGW toolchain gains support for ARM64X. Querying Clang for the correct file name is
the most forward-compatible approach.

Ryan Houdek 96363143de Linux/SMCTracking: Stop calling mprotect on a memory region times the number of threads
I noticed this cascade of mprotects when poking at Crypt of the
Necrodancer, since it consistently is invalidating code. I saw us
calling mprotect on the same page 32 times in a tight loop and thought
surely this isn't FEX doing this.

Turns out we were calling the callback after invalidating each thread.
It should instead be done once at the end of invalidating the thread's
caches while still holding the locks.

Fixes this weird cascade of mprotects that equal the number of FEX
threads.

Ryan Houdek cdbcdfe397 FEXServer: Fixes squashfs/erofs with newer fuse releases
Newer fuse releases changed how they are waiting on child processes to
exit. Setting the signal action to SIG_IGN would cause
erofsfuse/squashfuse to inherit the ignored action and cause their
internal `wait4` syscalls to fail with ECHLD.

Set the action back to default inside the FEXServer because our original
reasoning for setting the ignoring is no longer valid. FEXInterpreter
still ignores SIGCHLD while launching FEXServer.

Maybe fixes the muvm thing people have been complaining about.

Also fixes accidental comma delimiter usage.

Ryan Houdek fc052efb91 FEXCore: Fixes x87 reduced precision
With the change from #4538 I had accidentally broken x87 reduced
precision.

This is due to the fact that we accidentally lost ABI information about
interpreter fallbacks supporting `preserve_all` or not. So now instead
of having some ABI callbacks supporting it and some not, just force
usage of `preserve_all` if it is supported by the compiler entirely.

Fixes Steam when x87 reduced precision is enabled.

Ryan Houdek c5754145c5 FEXCore/JIT: Switch over to new vl64pair for RIP reconstruction
As said in the implementation of this struct commit message. This new
pair struct optimizes specific cases of small forward only increments
that can fit in to 8-bit space, and small forward or backward jump cases
that fit in to 16-bit space.

Some stats of this change:
- Steam: 5.88MB down to 4.34MB. 73.8% the space consumed
- Steamwebhelper: 15.8MB down to 13.24MB. 83.8% space consumed
- Sonic Mania: 3.6MB down to 2.58MB. 71.6% space consumed

As for absolute stats when compared to all code buffer size:
- Steam: 86MB of code buffer to 5.88MB -> 4.34MB of RIP reconstruction.
  - 6.8% -> 5% code buffer space used for RIP reconstruction
- Steamwebhelper: 285MB of code buffer to 17MB -> 14.26MB of RIP reconstruction.
  - 5.9% -> 4.9% code buffer space used for RIP reconstruction
- Sonic Mania: 48.53MB of code buffer to 3.55MB -> 2.53MB of RIP reconstruction.
  - 7.3% -> 5.2% code buffer space used for RIP reconstruction

Ryan Houdek 00acf4d327 FEXCore/Utils: Implement a new VL64Pair struct type
This new variable length pair of integer implementation is taking direct
advantage of the most common aspects of FEX's JIT in that most x86
instructions are <= 8-bytes in length, and the ARM implementations of
those are /usually/ 16 instructions in length or less. Also only
unsigned offsets in this implementation since the common case is forward
incrementing.

This converts a majority of 16-bit vl encodings in to an 8-bit encoding
instead, shaving space off the RIP reconstruction data.

An additional optimization is for the 16-bit pair of integers, we
continue this optimization through but with more bits and changing over
to signed. This captures the second most common cases of /slightly/
larger increments and small loops.

Pairs of 32-bit and 64-bit integers are unoptimized since they are
uncommon.

Ryan Houdek 5b9354cc74 JIT: Move interpreter ABI handlers in to the dispatcher
Fixes #4535

A handful of improvements on this.
* Reduces codegen around interpreter fallbacks
* Keeps ABI handling code in common Dispatcher code
* Improves I$ hitrate by most of the heavy code staying in Dispatcher

This cuts the amount of codegen inside the JIT for most interpreter
fallbacks by 1/2 or 1/3, by only doing the minimal amount of work in the
code blocks and doing most things in the dispatcher. The cost of which
is an additional branch per operation.

This should bring marginal performance improvements, but it should also
basically fall within noise. The bigger thing to care about here is a
smaller amount of code being generated for x87 blocks.

Ryan Houdek adcefe62cf InstcountCI: Changes how code size is calculated
Due to how jit block tail padding is working, there's no real good way
to determine the true "implementation size" of an instruction without
the backend being aware of wanting to investigate it.

Trying to inject another instruction, or another IR operation actually
subtly changes codegen in a way that gives invalid results. The only
real way to get around this is to inject a known token in to the
instruction stream as we `ExitFunction`.

So inject a `udf #0x420f`, and change the scanning behaviour to find the
first one and cut everything else off afterwards.

This already scoops out some code in some game blocks that were
accidentally landing ExitFunction code in the json.

This also has been tested to work with #4528 with its InstCountCI
specific changes reverted.

This means we don't need to play subtle padding tricks in the JIT to get
the information we want in InstcountCI.

Ryan Houdek c44d8eed35 LinuxEmulation: Fixes remaining memory leak on pthread teardown
With the previous stack leak fix, RUINER reduced its memory leaking down
to around 50MB/s. The remaining memory leaks come from the pthread stack
that we are required to allocate (128KB per thread) and some internal
DTV tracking structures.

The problems come in the fact that glibc/pthread only tears down its
internal state for these if the pthread function actually returns! We
can **technically** switch the initial stack over to a "user" stack but
that introduces more problems around internal dtv tracking that we
already fixed months ago, so we can't actually do that in practice.

This leaves us no choice, we effectively are mandated to return from the
pthread function in order to free the memory from glibc. The only way we
can safely do this is with a long jump and deferring some data structure
management until that case.

This is all incredibly sucky but it's necessary to work. With these
changes, RUINER is no longer leaking memory (Hovering at around 3GB used
while in-game) and even Steam is consuming less memory.

It doesn't solve the problem that thread creation and teardown could
likely be faster, but not many applications are creating 720
threads/second.

Ryan Houdek 86c492da13 LinuxSyscalls: Fixes a major stack memory leak
Fixes an issue where a thread that exits with the `exit` syscall never
actually frees its pivot stack. This is common practice and it was
missed when I was fixing the previous stack pivot leak.

This was uncovered when looking at the game
[RUINER](https://store.steampowered.com/agecheck/app/464060/?curator_clanid=4777282)
for timing bugs. Turns out the Linux build of the game creates and
destroys a VLC object every tick of the engine. Creating this VLC
object creates six threads behind the scenes. At what I assume the
default tick of the engine is of 120Hz(?) this would mean it is
attempting to create and destroy 720 threads per second, quickly
leading to memory exhaustion under FEX.

While this hits the biggest memory leak we have around thread creation,
this game is still hitting thread creation so hard that I can see other
leaks that I need to track down still.

JustinChi f371bf2bc4 LinuxSyscalls: Update signal mask at deferring time
In regular x86 programs, when a signal occurs, the signal will not be handled within the signal handler. However, under FEX's defer signal mechanism, the signal is not immediately masked when it is deferred. When returning to the location that receives the signal and continues processing, the signal might be received again, causing inconsistency between the emulation and the actual program.

Here is an unit test for this patch from ltp:

Luckily for us, this actually matches behaviour for what rdtscp does, so
we can take advantage of it if the host supports FEAT_ECV.

Ryan Houdek 0fbb6aa02f cephes: Rewrite to use softfloat-3e 128-bit
And also use it at the same time, since the function signatures changed.

Instead of relying on the host libc math libraries for `long double` ALU
operations, rewrite the entire thing to use softfloat-3e fixed width
float128_t types.

This is a very invasive change in cephes but is a necessary requirement
for getting the precision we require in environments that map `long
  double` to be the same as `double`, like Win32 and MacOS.

This fixes the precision issue in transcendental operations when running
under WINE.

This changes the instcountCI code to consistently load test data in to

This has been a minor annoyance where if a test was added, it had the
potential to shift the rest of the data in the tests. This now ensures

Ryan Houdek ffca27cbde FEXCore/Softfloat: Wire up cephes math library for transcendental operations
This is solving a different problem than what #4411 is specifically
trying to solve.

For our transcendental operations, we can't currently guarantee that
these functions will actually operate at the 128-bit softfloat
precision. While this is true with glibc, this is /not/ true for musl
and likely more libraries.

Instead of relying on our libc implementation to implement these,
instead include the cephes math library directly which is what most
people use for this. Including musl even, but not for all operations.

With this we are no longer beholden to the standard libraries for
providing a correct implementation.

Ryan Houdek f9b369c550 Telemetry: Removes unnecessary indirection
Telemetry value address generation was forcing an indirection at all
times which was unnecessary. These values live in the BSS, zero
initialized at process start and is unnecessary.

Instead change the wrapper defines to directly operate on the enum
passed in which saves an indirection on all of these telemetry
operations (except for the ones in the JIT which are required to be PIC
compliant).

This also fixes an annoying warning about
`FEXCORE_TELEMETRY_STATIC_INIT` causing initialization and destruction
order being unspecified, so two wins.

Ryan Houdek feab0bce4b x87StackOptimizationPass: Initialize a couple of arrays
Just to silence some warnings that think these aren't zero initialized

Ryan Houdek 0599d80b13 FEXCore/Frontend: Changes how VEX operand encoding flags are encoded
These three options are mutually exclusive with each other and could
potentially result in invalid encodings of the table on accident.

Change over to a 2-bit bitfield to encode if the operand that consumes
the VEX option is none, destination, 1st src, or 2nd src.

This ensures the table can't ever be incorrectly encoded.

Ryan Houdek 68939c5a5c LinuxSyscalls: Emulate futimesat syscalls
Since this syscall doesn't exist, we need to convert it to the
equivalent utimensat like the kernel does internally.

This is fairly trivial but there are some safety nets in place.

Also some of these static_asserts were testing the constraints of the wrong
class, so we can tidy those up as well.

the new code is the same instr count on flagm although probably an extra uop.
the inst count regression is on flagm, but we can't tolerate broken behaviour.

Alyssa Rosenzweig bc87c3d494 ConstProp: optimize StoreContext(128-bit zero)
Turn this into stp to save a move in a /ton/ of AVX-128 code. It's pretty
annoying to optimize this at the dispatcher level because of the SRA cache, so
doing it in the ConstProp is a nice compromise solution.

Somehow I had completely missed this and recent reciprocal tests have
exposed it as a problem. When AFP is supported but not RPRES then we
were hitting this code path.

We were failing to insert in to the destination correctly, which because
the reciprocal is calculated using fdiv using a synthesized constant,
this would just zero the remaining portion of the register.

When the shift size is exactly 16bytes, then it turns in to a move.

the OpcodeDispatcher, so the backend doesn't synthesize and not cache.

Ryan Houdek 44492b4828 SignalDelegator: Clear DF and RF on signal
The Linux kernel clears these flags on signal, DF is particularly
dangerous because it would break ABI if a signal happened to occur in
the middle of a memory operation that changed the direction of copy.

Because of how frequently wine uses signals, this is actually fairly
likely to occur inside of a memcpy/memset function.

Ryan Houdek 46d0df9cba ArgumentLoader: Fixes double load
The argument loader was loading configuration from the arguments twice.

The use of the argument loader needs to preload the arguments before
being handed off to the config system. This way we can pull remaining
arguments that get passed to the guest application.

Due to this, `Load` was getting called twice, once in the constructor
and once in the Config system. This was causing the backend to allocate
twice as much memory since the second load appends the arguments to a
fextl::list internally.

Not really any functional change but it was causing some heartburn with
some changes I was working on.

Ryan Houdek e718fc35f8 OpcodeDispatcher: Reuse PSHUFD shuffle mask for sha data shuffling
We already have this mask generated, and because sha instructions
typically don't exist in a vacuum it is actually beneficial to cache the
mask and use a single tbl instruction per shuffle.

OpenSSL has 12 sha1 instructions in their hot loop as an example, so
this would be a fairly good reduction in that loop. Sadly we don't have
it in instcountci, instead having their sha256 hotloop instead (Which
currently doesn't have sha256rnds2 optimized).

Even in a vacuum this is technically 1 instruction savings for each
instruction which is nice.

Saw these while scanning around. Funnily it makes it look like libnss is
worse off because there are multiple instructions using the same table
lookup to swizzle. So one instruction turns in to two.

We don't have a way to choose one path or the other, so it's usually
better to go the route that the instruction in a vacuum is improved, so
on average it is also improved.

Ryan Houdek 982a05450c FEXpidof: Fixes searching for wine applications
I kept finding I needed `./fex_shm_stats_read `FEXpidof Celeste.exe``
but FEXpidof wasn't ever wired up to find FEX in the face of emulating
wine and arm64 wine.

This adds two new features basically:
- If x86 wine is being emulated, then walk the argument list just like
  our config options to see what the program executable name is.
- If it is arm64 wine using FEX, then we need to detect that, and walk
  the arguments in a similar fashion

The detection is the main thing here in that the only way to detect FEX
for arm64 wine is checking the applications mapped files and seeing if
it is mapping arm64ecfex.dll or wow64fex.dll.

x86 Wine is easy since that's just skipping the wine{64,}{-preloader,}
arguments to get to the executable name.

This would become an issue when multiple threads are contending with the SIGBUS handler on the same code.

We were failing to mask the VR, OPC, Rm, and Option bits, resulting in a
comparison below always resulting in a false result if another thread
managed to backpatch.

This was just unlikely to be seen on LRCPC2 supporting hardware and
since we fixed `LDSTUNSCALED_MASK` before, this wasn't really getting
seen.

Tony Wasserka 391f9aa97d Profiler: Add Tracy backend
This differs from the existing GPUVis backend in a number of ways:
* Tracy is optimized for minimal overhead and nanosecond-resolution profiling
* Tracy supports live tracing (in addition to capture-based operation)
* Tracy has a richer feature set and a more polished UI (notably, statistics and histograms are generated out-of-the-box)
* GPUVis supports tracing multiple processes, whereas Tracy is single-process only

To use this backend, one of the environment variables FEX_PROFILE_TARGET_NAME
or FEX_PROFILE_TARGET_PATH must be defined to select the application under
profile by name or by path suffix.

Additionally, FEX_PROFILE_WAIT_FOR_FORK=1 may be needed for games that fork on startup.

Based on #4291 and #4324. Ideally this gets merged at the same time so
we can have Mangohud be on version 2 before giving them an upstream
patch.

Performance-wise this change falls within noise of my x87 microbench.

This just lets us track the number of float fallbacks FEX does, letting
us detect things like x87 fallbacks and how frequent they are, so we can
detect if a game might be slow or stuttering because of these fallbacks.

This is preparation work to allow passing the corestate to the x87 soft

Performance-wise, this change falls within noise because it basically
moves the GPR->Vector moves from the JIT in to C code, my microbench saw
the largest excursion of 5% but that's still within noise in the current
design of my bench.

A more tangible win from this change alone is less codegen on the JIT
side.

Ryan Houdek 8876047875 FEXServer: Fixes background startup
The problem here is that the pipe we used for telling FEXInterpreter
that the FEXServer is ready to accept connections was inherited by
erofsfuse or squashfuse. So the closing of the pipe from the FEXServer
side would leave a reference open in squashfuse or erofsfuse.

Fix this by setting FD_CLOEXEC on the pipe, but also pass the pipe FD
through an argument instead of scanning for all pipes.

Then once we execve the squashfuse/erofsfuse application, the FD isn't
inherited.

Billy Laws 151fc5e97f Frontend: Split blocks at jump target boundaries
With the prior approach, backwards jumps into existing blocks would
explore the overlapping part rather than splitting the block, generating
needless code and wasting time decoding. Similarly, the current block
wouldn't be split when it is extended to overlap with a pending jump target.

Solve this by tracking blocks in a sorted vector and splitting existing blocks
on jumps when appropriate, in order to avoid any possibility of overlapping
blocks, which would break the lookup, misaligned and zero instruction blocks
are disallowed.

Ryan Houdek dcfbc2f20e FEXCore/JIT: Encode the JITRIPReconstructionEntries using variable length integer
When #2722 implemented this initially and #4271 switched over to signed
int16_t there was assumptions made that int16_t was a reasonable
trade-off in encoding size versus needing to deal with 8-bit values
being too small in some cases.

In the common case we are almost always encoding 8-bit values because
instructions are typically linear (and less than 15-bytes in size), but
16-bit was chosen because optimizing JIT and multiple instructions that
don't cause exceptions can add up to larger than 8-bit.

Instead of hardcoding 16-bit values, implement a variable length integer
class where ~96.8% of values are 8-bit encoded, and the remaining 3.19% are encoded using 16-bit.
Due to some constraints that #4271 put in place, we can basically
guarantee currently that branch targets are within 16-bit. The VL class
does support 32-bit and 64-bit as well so if we change behaviour then
nothing needs to change.

Some stats when running Sonic Mania with multiblock enabled.
Encoded integers: 3,504,907
Encoded 8-bit:    3,393,095 (96.8%)
Encoded 16-bit:     111,812 (3.19%)
Encoded 32/64-bit:        0

Encoded Size:       3,615,181 bytes (3.44MiB)
Fixed encoded size: 7,007,604 bytes (6.68MiB)

Definitely worth using and saves the headache of large RIP/PC offsets
causing problems.

When multiple threads simultaneously SIGBUS on the same address, one of them
will perform the backpatching while the other will detect the backpatched
instruction sequence and hence report the SIGBUS as "handled".

This typo broke the instruction detection logic: The second thread would
assume the source of the SIGBUS was unrelated to TSO emulation and hence
report the signal as unhandled (generally triggering program abortion).

In practice, this problem did not manifest as FEX does not currently share
CodeBuffers between threads.

Ryan Houdek 48ad9e9a87 Allocator/FlexBitSet: Fixes a rounding issue with small allocation regions
When small regions were being used for VMA allocations (less than 64
pages), this function was truncating the result to zero. Resulting in
incorrect `LiveVMARegion` size calculations. It would calculate that the
FlexBitSet consumes zero bits of space, even though it needs to use at
least 2, or 3 if we actually want to allocate anything from that
LiveVMARegion.

This was noticed in this PR because our VMA region tracking is being
used more, which has a more likely chance to have small VMA regions for
allocating from. Cause a 1page allocation to try and use a 3 page VMA
region for allocation, but failing because the FlexBitSet size wasn't
calculated correctly.

- Page layout:
- [0x0, 0x1000):    struct LiveVMARegion
- [0x1000, 0x2000): FlexBitSet<uint64_t> UsedPages
-  ^ This space wasn't allocated/mprotected due to the size not
   calculating correctly.

Ryan Houdek c75778abeb FEX: Allocate a VMA allocator when running on a 48-bit VA
When running on a system with a 48-bit VA, if FEX does any allocations
between us reserving the upper 128TB and the application running, then
/technically/ we are intersecting with the application's memory region
in the lower 47-bits.

This didn't typically result in any problems due to how ASLR works, but
if we did any large allocations (like #4291 wants with 128MB VMA region)
then these typically get pushed higher in the VA space.

Again not usually a problem, but if you happen to be running an
application that is using MAP_FIXED with hardcoded addresses then this
can stomp over FEX-Emu memory causing problems.

This is what happens with Wine, it reserves the upper-32MB of its 47-bit
VA space, which is /highly/ likely to stomp on FEX memory. In-fact it
likely occurs all the time, we just got lucky with whatever it was
clobbering wasn't used at the time.

On 39-bit VA systems this isn't a problem because the mmap fails
outright with a warning message from WINE.

Because we are already reserving the upper 128TB of VA space, instead
just always enable our allocator and use the regions that were reserved.
We need to be a little bit careful to ensure we don't accidentally
allocate more memory post-reservation but that just requires a small
adjustment to our unique_ptr and constructor for the 64BitAllocator.

This means /all/ FEX-Emu allocations will be in the upper 128TB VA space
when running 64-bit applications on a 48-bit VA system. Which is kind of
nice.

Fixes WINE in #4291 when the allocator stats are bumped to 128MB per
process.

Billy Laws 486dc974c4 CPUBackend: Make guest RIP reconstruction offsets signed
With multiblock enabled, host code generated from guest code with a
lower address may be placed after host code generated from guest code
with a higher address in a multiblock. As each guest RIP reconstruction
entry is always relative to the one before it the offset needs to be
signed to allow this.
2025-01-17 21:49:43 +00:00
Billy Laws 3b1fbbc766 Frontend: Disallow cross-page branches in multiblock
This avoids both the generation of multiblocks that cover massive spans
of guest code, which causes issues for both context reconstruction
overflowing the RIP offset and attempting to decode branch targets
in unmapped memory regions.

Once support for querying mappings from the FEX frontend is in place this
limit could be increased if necessary, but this seems fine for now.

The thread termination callback can be called for other threads in the

and accept the small leak for now.

Ryan Houdek 4cfb81156f FEXLoader: Increase minimum kernel requirement from 5.0 to 5.15
Brought up in #4225 where it had issues with Openat2 which was added in
5.8.

The main driving force around minimum kernel version requirement is that
the lowest kernel version in our CI is 5.15. A benefit to this choice is
that this is an LTS release, which is also what Ubuntu 22.04 is
shipping.

Once the single CI machine is fixed to ship something newer then the
next logical choice would be kernel 6.1 which is also LTS, but until
then just lift it to 5.15. This version was released in October 2021,
and is supported by the kernel developers until 2026. Our previous
minimum of 5.0 was released in March 2019, so a two year leap here.

This removes the openat2 workaround that was necessary to pass our CI
since it is no longer necessary.

Ryan Houdek 12dc16780f OpcodeDispatcher: Fixes FEX's H0F3A table handling of REX.W
Most of this table ignores REX.W, but two encodings change behaviour
based on REX.W. These two encodings are PEXTRD/PEXTRQ and PINSRD/PINSRQ.

For every other instruction encoding, they will ignore REX.W, but FEX
was requiring that they didn't have REX.W encoding. I had special cased
this in the past by adding PALIGNR, but that didn't handle any of the
other instructions.

We can't just handle REX.W in the OpcodeDispatcher and remove the two
special cased instructions because these vector operations also interact
with instruction prefix 0x66 which changes the operating size to 16bit
with regular instructions.

So instead just generate all listings of instructions with REX.W being
zero and one and install handlers in all cases.

- Parse the shebang line properly (use FHU::ParseArgumentsFromString

- Make native-interpreter shebang files work by deferring to the kernel
  in that case (previously, they'd get executed through the loader and
  it would choke on the architecture of the interpreter)
- Do not use the RootFS-prepended path when executing shebang files. The
  loader will prepend that anyway when looking it up, but it needs the
  bare guest path so it can pass it as an argument to the interpreter,
  which (since it's emulated) will do the lookup through the RootFS.

Asahi Lina c161fd218c FileManagement: Simplify emulated file lookup
To locate whether a path is in the emulated list, EmulatedFDManager::OpenAt()
attemps to resolve the path. realpath() ends up calling readlinkat() on
every path component, which is a lot of syscalls for every open()
variant syscall. It also makes interaction with the rootfs complex and
error-prone.

There's a much easier way to do this: We just open the file without
emulation and check its real path via get_fdpath(). This is just one
readlink() syscall per open, instead of one per path component. If the
file turns out to be emulated (uncommon case), we swap out the fds.

This also decouples EmulatedFDManager from guest path resolution
entirely, so it will never fall out of sync with the RootFS logic.

Ryan Houdek 38fa866c91 Utils/FileLoading: Fix LoadFileImpl
It is not an error that pread returns /less/ than what was requested. In
fact it's very common for the Linux kernel to return less than the data
requested from procfs.

procfs keeps coming back to bite this function, previously it was fstat
returning size of 0 which it hit. Now it only feeds data as much as it
wants per loop. In particular /proc/self/maps would only read ~3k bytes
on my system, but not be complete.

To fully fix the issue, always make sure to keep reading until there is
either an error OR zero is reached!

When an SMC trap happens: reconstruct the context before the SMC write
then compile the write as a single instruction block to reduce it to
regular SMC. SMC where the writing instruction is the instruction being
patched will hit the signal handler at most twice: the 1st will trigger
the write to be compiled as a single instuction block, the 2nd will
detect inline SMC of a single instruction block and then just take the
usual invalidate+reprotect+continue step, avoiding a potential infinite
loop of recompilation.

Billy Laws 981c3009ee FEXCore: Emulate EFLAGS.TF
When set - either via POPF or a thread context operation - the trap flag
raises a single step exception after the execution of each instruction.
As e.g. a JUMP instruction with TF set will raise an exception at the
jump target. Handle this on the FEX side by storing both the flag itself
(in bit 0) and a 'block exceptions' flag (in bit 1, inverted). Each
generated block when TF is set is then forced to a single instruction
with logic to raise the exception at the start. Initially after setting
TF exceptions are blocked, then at the start of the block they are
unblocked so that after the instruction executes an exception is raised
at the start of the next block.

Ryan Houdek beec203f56 LinuxSyscalls: Fixes exit syscall
if an application is using `exit` then it is usually a faulting
condition rather than cleanly exiting. When cleanly exiting
applications will typically use `exit_group` instead.

`exit` is useful to quickly cause a single thread to exit in a
multi-threaded environment as well, where `exit_group` will take down
the entire process group.

FEX had implemented this in a way that would do a double Stop signal,
cascading to a crash. When tied in to a crash handler, this could get
caught in a weird way.

This /should/ fix #4198, but I can't confirm locally. It looks like in
that issue that the steam install is slightly buggered (as evident by
missing srt-logger and steam-runtime-identify-library-abi).

This is a bug regardless so fix it and create a unittest. If it doesn't
fix the user's bug, then we have another workaround that will definitely
solve it.

Ryan Houdek efb276f489 FEXCore: Removes ExitHandler and RunUntilExit
Now that all the threading behaviour has been correctly separated/moved
to the frontend, these functions serve no purpose.

- Instead of using RunUntilExit, all threads can use `ExecuteThread`
  directly, since there's nothing special about the primary thread now.
  - This also removes the public function definition of `ExecutionThread` since that was only used for threading logic.
- Instead of using an exit handler, just do the same cleanup after
  `ExecuteThread` has returned.
  - Just make gdbserver is cleaned up early if it exists since it may
    want to send some things to the connected gdb instance before
    threads are exited.

Ryan Houdek e7e59204d3 FEXCore: Removes remaining RunningEvents from InternalThreadState
These are all frontend constructs with mostly deprecated constraints.
WaitingToStart isn't used anymore, Running is effectively always true
(and behaviour has changed that if a thread is alive, it's running).

The only one that remains is `ThreadSleeping` which is only handled in
the frontend, and there was some conflation between ThreadSleeping and
Running which was hard to gauge. So delete `Running` and
`WaitingToStart`, but move `ThreadSleeping` to the frontend.

We were using this variable for two things, letting the frontend signal

conflated with one another and actually makes things more confusing.

- Move StartRunning/StartPaused to the frontend, because its a construct
  that only needs to exist in the frontend
- Adds a FEX::HLE::ThreadStateObject CV for handling pausing, which only
  needs to exist for gdbserver

Ryan Houdek 3ecc66fbcf FEXCore: Moves TLS initialization for Alloc::OSAllocator
Alloc::OSAllocator uses a TLS variable of the thread object so it can
use a forkable mutex plus a deferring signal section. This was setup
when the FEXCore "ExecutionThread" function is called, which is a bit
awkward and is an artifact from when the thread creation was mixed
between the frontend and the backend.

Instead let the frontend inform the backend when to install the TLS
variable.

This is one step required to make GdbServer work correctly again since
the thread initialization and pausing is awkward today.

Asahi Lina d761fc44f4 FEXServer: Listen on both abstract & named sockets
Abstract sockets have one limitation: they are bound to a network
namespace. Chromium/CEF sandboxes using a new netns, which breaks
connecting to the FEXServer.

To work around this, use and try *both* abstract and named sockets. As
long as either the filesystem or the network is unsandboxed, things will
work. If both are sandboxed, there isn't much we can do... but at that
point we shouldn't be reinitializing the FEXServer connection anyway
since the FS should be available on FEXInterpreter startup.

Asahi Lina 73ffaa1e18 FileManagement: Hide the FEX RootFS fd from /proc/self/fd take 2
Apparently Chromium/CEF can chroot or otherwise sandbox the filesystem
away before forking and checking for directory FDs, making /proc
inaccessible, which means we can't stat it for our inode check, breaking
the hiding.

So, double down on things and do what Chromium does: open an fd to /proc
ahead of time, so that continues to work. Then we use it to update the
inode of our RootFS fd instead, and finally, also do the /proc fd itself
to hide that one too.

We also don't need to check the st_dev of /proc more than once, since
that's not expected to change anyway.

Fixes cefsimple.

JIT: Moves Arm64 JIT up one folder
2024-10-27 17:10:26 -04:00
Asahi Lina 3d701f5fcf FileManagement: Hide the FEX RootFS fd from /proc/self/fd
Chromium/CEF has code that iterates through all open FDs and bails if
any are directories (apparently a sandboxing sanity check). To avoid
this check, we need to hide the RootFS FD. This requires hooking all the
getdents variants to skip that entry.

To keep the runtime cost low, we keep track of the inode of
/proc/self/fd/<rootfs fd> (note: not the RootFS inode, the inode of the
magic symlink in /proc), and first do a quick check on that. If it
matches, then we stat the dirfd we are reading and check against the
procfs device, to complete the inode equality check.

As an extra benefit, this also fixes code that tries to iterate and
close all/extra FDs and ends up closing the RootFS fd.

it. Noticed this while cleaning up in #4134. Removes one instruction for

Ryan Houdek fe5bc02682 FEXLoader: Fixes newer wine versions and Fedora
This was brought up by #3831 but I finally got the courage to look at
the hard problem.

Although I'm only tackling half of the problem with this PR, which is
that FEXLoader needs to strip the rootfs path from the executed path if
it begins with the rootfs, plus some changes to the surrounding code.

The primary concern here is that when an application has been executed
under FEX, specifically through binfmt_misc, then FEX needs to prepend
the full rootfs path otherwise Linux can't find the program.
Additionally execveat with an FD will resolve a full path to the rootfs.

So past FEX's initial setup, we need to strip off the rootfs path to
provide an "absolute" path that is visible to the guest application
later. Which is kind of funny since we have a `RootFSRedirect` function
which did the exact opposite. This was due to legacy problems in the
original ELFLoader that couldn't handle symlinks correctly, which has
since been resolved, so that no longer needs to exist.

There was also some weirdness in `GetApplicationNames` where the passed
in argument list was modifying Args[0] and then saving the Program as
well. Which I just got rid of. Also stopped passing in the arguments by
value because....why did I write it like that?

In InterpreterHandler we now need to check if we can open the path
inside the rootfs or fallback without it. Plus I had to change the
shebang handling so it stopped prefixing the rootfs AGAIN. Took the time
to change the shebang handling there so it stops creating string copies
and instead just generates views.

Overall this fixes a fairly major flaw with how we were representing
`/proc/self` to the application, which was breaking wine since it would
prefix the rootfs multiple times, which was weird.

It doesn't address the remaining problem in #3831, which is that
applications can still see some of the leaky abstractions with symlinks
through the rootfs, but I want to get at least this step in.

Ryan Houdek 7c6444c37c unitests/ASM: Removes unused MemoryRegion configs
FEX's ASM unitests had the problem that they were copy and pasted
templates and MemoryRegion was copied in to almost all tests.

Very few tests actually use the MemoryRegion they were asking for and
instead used none, or the hardcoded memory regions that the
TestHarnessRunner provides.

This is entirely a sed replacement and minor fixups plus reverts for the
few tests that actually use the region asked for.

Ryan Houdek 4a179c8f87 TestHarnessRunner: Fixes FS/GS usage in tests
When writing `FEX_bugs/tls_vector_element.asm` I had to switch to using
GS segment instead of FS segment because the unittests didn't correctly
restore FS after running. This is because GS is unused on Linux
applications, but FS would become broken and break glibc cleanup on
shutdown.

Now that xbyak has been updated to v7.09, it now supports
{rd,wr}{fs,gs}base which allows us to save and restore the segments
correctly. This lets us drop in TLS tests in to unittests more easily
now.

Ensured this works by modifying the test temporarily to use fs instead
of gs again, seeing it crash before HostRunner changes, and work after
HostRunner changes.

Fixes #4104

Ryan Houdek 0bb0f9cec7 unittests/ASM: Ensures FNSAVE and FRSTOR only store as much data as required
The instruction definition only allows these instructions to load/store
94 or 108 bytes, not affecting any bytes afterwards. This is a bit
awkward because 80-bit x87 registers are stored at the end.

FEX has an optimization today where it uses overlapping loads and stores
for the first seven x87 registers, and a split loadstore for the final
register. This ensures that we get the correct data while reducing the
number of loadstores.

We didn't have a unittest in place to ensure we only ever write the
correct amount of data, so changes like in #4107 which look correct from
an initial glance, would have resulted in broken behaviour.

This unittest ensures both that the instructions don't try to access
beyond the end of the page, and also ensures that they don't overwrite
subsequent data. Making sure that potentially broken behaviour doesn't
make its way in.

Sergio Lopez 5c51c54ccc FEXCore: adds support for compat input prctl
The size of the input_event struct differs between 32 bits applications
and 64 bits applications. To deal with this, the kernel implements a
compat variant for the input syscalls, but it's only enabled for 32 bit
processes.

In libkrunfw we're introducing a prctl that enables a 64 bit process to
request the kernel to enable the compat variant for the input syscalls.
This commit makes use of that interface for enabling/disabling the
compat input variant as required.

The visible effect is that input devices such as gamepads work properly
on emulated 32 bit applications.

2024-09-28 15:26:35 -04:00
Ryan Houdek 0f54369f9b VDSO: Implements v6.11 vdso getrandom
This is an interesting vdso implementation because it only exists in
x86-64 with kernel v6.11. For Arm64 the implementation is likely to land
in a couple kernel versions from now.

Some differences with vdso_getrandom versus the regular getrandom
syscall
- Has two additional arguments, opaque_state and opaque_len
- Expects the userspace to mmap/munmap this opaque state structure
- Lets userspace query information about this structure upfront
- If the opaque data structure isn't provided then it falls back to
  regular SYS_getrandom

With the "glibc" implementation, we can tell the interface to allocate a
single page that gets unused (otherwise glibc ends up not using the
interface), and fallback to the regular SYS_getrandom.

In the case of the vdso interface, currently the arguments just get
passed through.

Keeping this as a WIP until the ARM64 kernel patches land and I can
actually test the things. Running the "glibc" path works today with the
selftest, but the vdso path is currently completely untested.

These extensions are almost immediately getting picked up by mesa and

Once again updated as described in #2076. This is starting to take more

Ryan Houdek 77b801b8ae FEXConfig: Add the ability to watch and configure global rootfs
Global rootfs doesn't support a named rootfs (only local supports that).
So when it is a global rootfs option just give the full path to the
config path.

Just needs some special handling to ensure the full path is retained for
global paths.

A reimplementation of #4067 that doesn't hardcode paths and routes the
global data path through FEXCore.

Ryan Houdek 58bcf691d6 Linux: Optimize CreateNewThread stack usage
We were creating a copy of the FEXCore::Core::CPUState object when we
didn't need to. We can pass the host thread's CPUState frame through to
the creation handlers since it's read-only (so modify it to be const).

We then just move the RAX and RSP setting to /after/ the CreateThread
handling instead of before.
This reduces stack usage from ~1392 bytes to ~80 bytes.

Previously reported as some old CPU without AVX and SSE4 and other

Start advertising as something more modern that actually shipped with

family and model checks rather that CPUID features checks.

Also removes the silly `(ES)` tag from CPU-Z.

Also moves generation in to a constexpr function that can actually range
check these 4-bit and 8-bit values.

Ryan Houdek 37a70e2ec6 FEXCore: Convert Base tables over to constexpr
Only doing the single table for review purposes. Once reviewed I will
hammer out the remaining tables.

Similar to #3320, most of the OpcodeDispatcher tables can be consteval
and made to be a compile time constant. This just requires shuffling the
code slightly. The idea is to get almost all of the table setup out of
the `InstallOpcodeHandlers` function and instead only install the
handlers that change based on 32-bit or 64-bit, just like the x86 tables
we also did.

change their opinions, just remove the code from FEX since it's never
going to happen.

Removes a little bit of confusing behaviour in execveat and
filemanagement handling. Leaving us with only the regular confusing
behaviour of trying to track accesses to `/proc/exe` instead.

2024-09-11 13:59:24 -07:00
Ryan Houdek e8b51ac0a4 FEXServer/PipeScanner: Stop writing null to incoming pipes
This was causing problems in a typical use case of piping stdout/stderr
to another application. So if FEXInterpreter was started, with stdout
piped to another application, and FEXServer wasn't running so a new
instance needed to be started. FEXServer would write a null to every
pipe then close it. This includes the stdout that is being piped to the
new application!

This writing was legacy behaviour before FEX was properly listening to
POLLHUP and is no longer necessary. Just remove the writing completely
to fix this issue.

Easiest test case was just `./Bin/FEXInterpreter `which ls` / | xxd | head -n 3`

Returned:
```
$ ./Bin/FEXInterpreter `which ls` / | xxd | head -n 3
00000000: 0000 0000 6269 6e0a 6269 6e2e 7573 722d  ....bin.bin.usr-

```

That first null shouldn't be there.

Ryan Houdek e4bfbda008 VDSOEmulation: Stop using dlopen for VDSO
We have been relying on the
`YesIKnowImNotSupposedToUseTheGlibcAllocator` fault avoidance for a long
while now. The plan was to rewrite the symbol fetching in the future to
avoid this since VDSO is kind of special anyway.

That time is now, I have had this VDSO symbol parsing code living in a
different project for a few months now and it is working great.

The basic things here are that the Linux kernel provides the VDSO
mapping base pointer through the auxv value `AT_SYSINFO_EHDR`. We then
need a minimal ELF parser that /only/ parses the dynamic symbol header
(and accompanying string header).

Then it's a simple case of walking the symbol table and recording the
pointers. Confirmed this fetches all the correct symbols (As I've been
using it for a while already I already knew it worked.)

This lets us stop allocating memory through the glibc allocator due to
dlopen.

Ryan Houdek f51832ca6b FEXCore: Fixes a bug with VPSRLDQ/VPSLLDQ with >= 16-byte shifts
When the shift amount is >= 16-bytes then we need to zero the register.
We had a bug where we were assigning `Result.High` to itself, which
effectively made the top 128-bits of the ymm register not modify itself.

Adds a unit test to ensure that doesn't happen again.

Billy Laws 621af9e7e8 ARM64EC: Switch to exception-based native syscall dispatch
The previous approach assumed that ntdll wouldn't have been patched
before FEX was loaded, but that isn't necessarily the case thanks to
CEF. This takes the same approach used by xtajit which wine recently gained
support for wine. The overhead to this isn't ideal but most syscalls
aren't directly done through x86 code anyway and in the future FEX could
forward unpatched thunks to their ARM variants at JIT time.

Ryan Houdek fd4f6b8020 FEXCore: Dynamically scale TSC
When I implemented TSC scaling originally, I chose a scale factor of 128
because it basically covered the range of devices we cared about without
going too high. I also only tested devices that had a TSC scale factor
from 19.2Mhz to 34Mhz. Turns out there is hardware that also has a 48Mhz
cycle counter, which cause them to effectively have a 6.1Ghz cycle
counter, which is kind of absurd.

Instead of a fixed scale, just calculate the amount of scaling we need
to get >= the minimum threshold of 1Ghz. This will change the shift from
7 to 5 or 6 for the faster cycle counter devices.

Of course if someone wants to know the scale factor they can still use
cpuid function 15h to know it.

Ryan Houdek ac32876e4e LinuxEmulation: Implement support for seccomp
Seccomp is a relatively complex feature that was added to Linux back in
2005, and was further extended in 2013 to support BPF based protections.
Once seccomp is enabled, you can no longer disable seccomp but
additional protections can be placed on top of existing seccomp filters.
Additionally seccomp filters are inherited in child processes, which
ensures the process tree can't escape from the secure computing
environment through child processes.

The basis of this feature is a shim that lives between userspace and the
kernel at the syscall entrypoint.
In "strict" mode, seccomp only allows read, write, exit, exit_group, and {rt_,}sigreturn to function.
When in "filter" mode, a BPF filter is run on syscall entrypoint and
returns state about if the syscall should be allowed or not. Multiple
filters can be installed in this mode, all of which get executed. The
result that is the most restricted is the action that occurs at the end.

There are some significant limitations in filter mode that must be
adhered to which makes executing this code inside of kernel space a
non-issue and effectively limits how much cpu time is spent in the filters.
Although these filters are free to do basically anything with the
provided data, just can't do any loops.

FEX needs to implement seccomp because there are multiple applications
using the feature, the primary one being Chromium which some games embed
without disabling the sandbox. WINE also uses seccomp for capturing
games that do raw Windows system calls. Apparently Red Dead Redemption
is one of the games that requires this.

While FEX implements seccomp, it is not yet all encompassing, which is
one of the reasons why it isn't enabled by default and requires a config
option.

**seccomp_unotify is not implemented**
This is a relatively new feature for seccomp which lets the seccomp
filter signal an FD for multiple things. Luckily Chromium and WINE don't
use this. This will be tricky to implement under FEX since it
requires ioctl trapping and some other behaviour

**ptrace isn't supported**
One feature of seccomp is that it can raise ptrace events. Since FEX
doesn't support ptrace at all, this isn't handled. Again Chromium and
WINE don't use this.

**kill-thread not quite correct**
This isn't directly related to seccomp but more about how we do thread
shutdown in FEX. This will require some more changes around thread state
tracking before fully supporting this. Chromium and WINE don't use this.
kill-process also falls under this

Features that are supported:
- Strict mode and seccomp-bpf mode supported
- All BFP instructions that seccomp-bpf understands
- Inheriting seccomp through execve
   - This means we serialize and deserialize the calling thread's
     seccomp filters
   - An execve that escapes FEX will also escape seccomp. Not much we
     can do about it
- TSync - Allowing post-mortem seccomp insertion which allows threads to
  synchronize seccomp filters after the fact

Features that are not supported:
- Different arch qualifiers depending on syscall entrypoint
  - Just like our syscall handler, we are hardcoded to the arch that the
    application starts with
- user_notif
- ptrace
- Runtime code cache invalidation when seccomp is installed
  - Currently we must ensure all syscalls go through the frontend
    syscall handler
  - Runtime invalidation of code cache with inline syscalls will get
    fixed in the future.

This currently isn't enabled by default because of the minor feature
problems that haven't been resolved. Currently the Linux Kernel's test
application works for the features that FEX supports, and WINE's usage
can be handled by FEX. Chromium's sandbox doesn't yet work with this PR,
but it only fails due to features unrelated to seccomp.

Having this open for merging now so we can work to resolve the remaining
issues without this bitrotting.

This must have happened during a refactor or something, but since we're

version /prior/ to loading host VDSO symbols.

Moves the VDSO thunk definition setting to the end after VDSO symbol
definitions in order to get host VDSO symbols working again.

2024-09-02 10:14:52 -04:00
Ryan Houdek 9056d9b9de SignalDelegator: Refactor how thread local data is stored
Two primary things here:
- Remove the static `GlobalDelegator`
- Move the thread_local SignalDelegator::ThreadState information
  directly in to ThreadStateObject

Having the ThreadStateObject and the SignalDelegator information
disjoint was confusing but was required when we didn't have any object
in the frontend that could have its own independent data. Since we fixed
this with the `ThreadStateObject` type we can now move this over.

The `GlobalDelegator` object is now instead stored in
`ThreadStateObject` instead.

Instead of using a thread_local variable, we now just consume 8-bytes of
the signal alt-stack since the kernel gives us that information about
where it lives. This then converts all the thread_local usage to use
either the passed in CPU state if it exists, or fetching it from the
alt-stack offset.

Very minor changes in behaviour here, will help when trying to improve
FEX's behaviour around signals.

This isn't even typically allocated in a real setup, as it's only a

The CallbackReturn function stays in FEXCore because it would have
caused an API in the other direction instead.

Ryan Houdek b19440c78f Arm64: Ensure 256-bit operations always assert without 256-bit SVE
Our JIT will happily consume incorrectly formed 256-bit vector operations in a lot of cases when the host CPU doesn't support 256-bit SVE.
This is what caused the bug in #4006. For every vector operation that
can consume a 256-bit size, add an assert that always checks if 256-bit
SVE is supported in those cases.

This will ensure that #4006 doesn't happen again.

Ryan Houdek 8bf4a124c8 AVX128: Fixes 256-bit float compares
Just like the bug in #4006, we were incorrectly passing a 256-bit
comparison in to the float compare IR operations. Once again it would
"safely" decompose in to 128-bit operations without issue.

PR #4007 added asserts to ensure that 256-bit operations aren't emitted
when the host CPU doesn't support 256-bit SVE and detected this.

Ryan Houdek 7e6ba184f9 AVX128: Fixes incorrect size usage in AVX128_Vector_CVT_Int_To_Float
This handler was incorrectly using 256-bit IR operation sizes. Due to a
quirk with our IR handling, this would "safely" fall back to a 128-bit
operation and work "correctly".

The problem encountered is that since the IR operation is claiming to be
256-bit, when the value got spilled due to register pressure then a
true 256-bit store and load operation would be generated. This would
then emit an SVE load and store, with the expectation of 256-bit SVE
loadstores. This caused a SIGILL on Oryon since it doesn't support SVE,
but even would generate an invalid predicated loadstore on SVE 128-bit
hardware.

Ryan Houdek c82a683987 Frontend: short-circuit code generation on invalid instructions with multiblock
A source of overhead with multiblock is hitting instructions through a
conditional branch that can never be executed. Usually AVX512
instructions in glibc. This causes us to emit partial blocks for a ton
of targets that will never get executed.

Instead, when we have multiblock enabled, if a block hits an instruction
encoding we don't support, then remove all the decoded instructions from
the block and early terminate it if it isn't the entry block. This
resolves the issue of emitting a bunch of IR and code for blocks never
executed.

If the block of code has an invalid instruction in the entry block for
decoding then it'll still emit code up to the invalid instruction and
raise a SIGILL. This has the potential for generating some additional
blocks of code if a game is abusing SIGILL, but since that's unlikely
it's a good trade-off.

Also removes a few log instructions that don't really provide anything
anymore and just show up as confusing messages when multiblock is
enabled.

Ryan Houdek 54d332935e Arm64: Implement support for strict in-process split-locks
For atomics that cross the 16-byte or 64-byte granularity, we need to
lock a mutex to ensure strict emulation of split-locks.

I took another look at these when I found out that Zen3 actually
implements split-locks. Not sure which architecture actually added
support for from them, but I wanted to ensure we have the ability to
handle this.

One thing that we can't handle in user-space is cross-process
split-locks through shared memory. This requires a kernel SIGBUS handler
to ensure a crashing/SIGKILL'd process doesn't lock all FEX processes in
the system.

This fixes a little split-lock abusing test that I have locally. It's a
bit flakey so it isn't viable to run in CI. Considering it is explicitly
testing a race problem.

Ryan Houdek 0dc0117e86 SignalDelegator: Make sure to defer a signal if the guest signal mask desires
Fairly trivial because we already supported deferring these signals. We
had just failed the final step of blocking the signal if we can't block
the signal (like with SIGSEGV, SIGBUS, etc).

Once the guest unblocks the signal mask with sigprocmask, the signal
will fire again.

Apparently older glibc relied on this behaviour for signal raising which
this fixes.

Ryan Houdek be9c5678c0 Arm64: Fixes SIGBUS handler for FEAT_LRCPC
When #3899 refactored some of this code, it had split an if-else chain
in to two independent if-else chains. Turns out there was a minor
dependency between them. Add back the few checks necessary to ensure
that FEAT_LRCPC falls through before hitting the FEAT_LSE checks.

This is necessary because their instructions share an encoding so the
masks between the two instruction classes overlap slightly.

Ryan Houdek 9c8438f264 FEXCore: Splits up atomic enablement checks
PR #3980 is adding a feature to merge loadstores in to paired
loadstores, but it was using the incorrect atomic check to determine if
it can safely merge them or not. It was using the GPR atomic check
instead of the vector atomic check. While this would improve performance
on Apple Silicon with its hardware TSO implementation, it would have had
zero impact on Cortex and Oryon.

Instead split out the three config options to live as a boolean check in
the ContextImpl similar to how we disable "AtomicTSOEmulation". Removing
the various configs in the JIT and CPUID so that it queries from the
same context. This makes it clearer that if you are wanting the current
active configuration for memcpy, vector, or general atomic TSO
emulation, you should query one of those three getters.

This also fixes a weird edge case bug in the arm64 JIT where you could
have TSO emulation disable, but still have vector TSO enabled partially.
Just because half a config wasn't checked in {Load,Store}MemTSO for
vectors. If the global "TSOEnabled" option is disabled then TSO should
always be disabled.

Alyssa will be able to pull this in to #3980 once merged and get the
performance uplift on Cortex and Oryon, since our default configuration
is to have vector and memcpy TSO emulation disabled.

Ryan Houdek 0ea3de95e0 SpinWaitLock: Update comment about WFE spurious wakeups
With recent bug fixes, WFE now can sleep for roughly as long as the
programmed architecture timer of 100 microseconds. Still nowhere near as
close as what x86 CPUs can get with waitx and waitpkg, because those
don't get spuriously woken up by an architecture timer.

100 microseconds is a significantly improvement over 52ns although.

Ryan Houdek f1055d0713 Arm64: On backpatch ensure DMB instructions get patched in first
In the case of a visibility tear when one thread is backpatching while
another is executing. The executing thread can /potentially/ see the
writing of instructions depending on coherency rules or filling of
cachelines.

By ensuring the DMB instructions are backpatched over the NOP
instructions first, this ensures correct atomic visibility even on tear.

Ryan Houdek 7875b20594 Arm64: Handle backpatching in a thread-safe manner
When code buffers are shared between threads, FEX needs to be careful
around backpatching its code buffers, since one thread might have
backpatched the code that another thread was also planning on
backpatching.

To handle this case, when the handler fails to find a backpatchable
instruction, check if it was already backpatched. This can be determined
by atomically reading the instructions back and seeing if they have
turned in to the non-atomic variants.

In most cases we can just return saying that it has been handled, in the
case of a store we need to back the PC up 4 bytes to ensure the DMB is
executed before the non-atomic store.

Ryan Houdek 2b26d0fff5 LinuxSyscalls: Implements less invasive assertion only EFAULT handlers
With the previous Copy{To,From}User helpers we need to actually
implement the handlers correctly. We want something that is a bit
lighter so we don't need to implement the faulting path in the syscall
handlers.

Implements a handful of helpers that just check for readable and
writable capability which can be thrown in to an assertion handler that
is zero cost in release mode.

Readable is checked by just attempting to read all bytes.
Writable is checked by attempting to read each byte and writing it back
to the same location.

Uses these helpers in x64/FD.cpp to showcase how they will be used to
detect EFAULT. Tested locally that they work correctly by writing some
small tests for the syscalls that expect EFAULT.

Alyssa Rosenzweig 9813553f02 json_ir_generator: introduce multidestination hack
We now have two types of destinations:

* regular destinations. These are SSA. You get exactly 1 per instruction. This
  is what almost every instruction should use.

* special destinations, introduced here. These are *not* SSA. They must be
  allocated with a special instruction (added later in this PR), and then they
  are mutated by the instruction. There are two types, either pure destinations
  ("out") or read-modify-write source+destinations ("in-out"). The former are
  useful for instructions that return multiple destinations, like Memcpy. The
  latter are useful for instructions that need a source tied with a special
  destination (currently just Pop, introduced later in this series).

Special destinations reuse the mechanism of sources, to get around the
limitations on regular destinations in our current IR. Ops with special
destinations desugar to ops with no destination but extra sources prefixed Out
or Inout.

They further require HasSideEffects so we don't optimize ourselves into corners.

Ryan Houdek 924723d433 LinuxSyscalls: Some minor cleanups
- We can have the SyscallFunctionDefinitions be the correct size out of
  the gate. Both tables are always 512 entries in size.
- In the RegisterSyscall_{32,64} handlers, just get the reference using
  operator[]. We always know we will be under the size of the array, add
  a an assert to check. Removes a bit of vector range checking overhead.
- Namespace 32-bit syscalls like 64-bit syscalls and include in the
  regular header like 64-bit. This was just an oversight
- Use std::fill for the syscall gap for the invalid syscall, just a
  minor cleanup.

No functional change.

Billy Laws ea4004ec9d ARM64EC: Support cooperative suspend
When a suspend request occurs on a running thread, Windows gives the JIT
~10s to pause and NtContinue with the x86 context. Resumption is then
done through BeginSimulation.

Billy Laws a469047e7a FEXCore: Support cooperative suspend on ARM64EC
ARM64EC doesn't have an explicit callback for suspend, instead this task
is delegated to the kernel setting a bool at a JIT-defined memory
location, as such the faulting based approach as was done for WOW64
cannot be used.

Billy Laws 9d9bd750e2 ARM64EC: Install a custom call checker to bypass NTDLL function patches
Some programs will hook the NTDLL exports that FEX depends on, the
regular ARM64EC call checker will detect such patches and invoke the
JIT to run them, which leads to infinite recursion if those same
exports are used during code compilation. Fix this by resolving all
patchable FFSs to their native ARM implementations for all indirect
calls performed by FEX, skipping any x86 patches.

bits.

Billy Laws 0e069f1e97 Windows: Introduce a minimal CRT replacement
It is dangerous for FEX to rely on the system CRT as calls can have side
effects that are also visible to the running application, and if patches
are applied to any CRT exports used during compilation the call checker
would trigger a reentry into the JIT to compile the patch and hence
deadlock. Only functions that FEX actively uses are implemented, with
the rest triggering an abort.

Ryan Houdek e84848b16b FEX: Moves HostFeatures querying to the frontend
This moves the CPU feature querying to the frontend. The primary purpose
here is for the wow64 frontend to not require linux-isms for querying
these features. This is required since non-Linux environments don't have
the "CPUID" feature for reading EL1 MSRs in EL0.

Wiring up the remaining wow64 registry querying is left for a future
exercise.

This also technically removes an xbyak requirement from FEXCore for when
building the x86 Test harness runner, but that doesn't really matter for
regular use cases.

Ryan Houdek e613876e9d AVX128: Optimize all cases of vpermq
Started by cherry-picking some cases from the variants that appeared when running
Steam, games, AV1 convolve tests, openssl, ffmpeg, libjpeg-turbo,
openh264, libvpx, gemmlowp, libyuv, and dav1d.

Then turned it around and optimized them all since all variants end up
needing to be split in to two halves, that effectively means we need to
have 16 implementations, plus a couple of special cases for duplicated
results.

Ryan Houdek 054c119e2e Config: Converts two LUT maps over linear scan arrays
These two maps used for environment lookup translations were getting
globally initialized and then registers with atexit handlers.

Switch over to a constexpr array and just do linear scans. This plus
short-circuiting the environment loader so it skips all entries that
don't start with `FEX_` has the side benefit of cutting the CPU time to
1/10th the time.

This plus #3917 removes the global static initializers entirely from
this file.

Billy Laws 4877bb3f19 ARM64EC: Support directly issuing the NtContinue syscall
This is required for handling SMC with the ResetToConsistentState
arguments as used in Windows, as using the NTDLL exported NtContinue
would wipe out any reserved registers in the ARM64EC ABI.

For Windows the syscall numbers are somewhat stable, and the SVC
instruction can be called directly. Since wine doesn't handle that on
ARM64, hardcode the system call number and manually call into wine
dispatcher. Once wine gains proper syscall thunks, those can be
parsed to get the number and the hardcoding dropped.

Billy Laws 910ec4aadd Dispatcher: Directly use the EC code bitmap for determining page arch
The prior approach using the L2 cache was flawed as it assumed L2
page entries had a 1-1 correspondence with actual pages. While the L2
cache could be extended to handle aliases with EC, this could lead to
thrashing etc. The cost of a lookup in the actual EC code bitmap is
cheap enough to perform every time considering the infrequency of calls
to ARM64EC code when compare to X86 L2 hits.

Instead of completely ddropping the deprecated path, support the new

the future API once pkg_resources gets deprecated and removed. Best of
both worlds.

Optimizes the AVX128 blends by reusing the prior SSE4.1 implementation.
Only difference is the destination register isn't reused as a source

One confusing thing is that Felix Cloutier's documentation has a typo on
the 256-bit VPBLENDW instruction where it had the top 128-bit lane
reusing the destination instead of sources. So I wrote a unittest to
ensure correctness.

stop prefixing the arguments when we generate allocate ops (in particular), this
is more convenient and simpler. in exchange we need to prefix Op to avoid a
collision on fcmpscalarinsert which has an argument named Op, but that's a local
change at least.

came up when experimenting with new IR, but I think this is probably a win by
itself.

Alyssa Rosenzweig e7d5a01c5f IR: remove F80Cmp flags
nothing is optimizing around this, it's just adding pointless complexity. if we
want to actually optimize F80Cmp, the right way would be to lift the
implementation into the OpcodeDispatcher or JIT. it wouldn't be terribly
difficult. This kludge doesn't get us closer there.

Billy Laws af3145674e ARM64EC: Fixup exception information for faulting x86 instructions
FEX emulates faulting instructions (e.g. ud2 or int 2d) by jumping to

thread context. Parse this out into a windows exception record structure
so the correct fault information can be seen by the guest.

Billy Laws 3c19e634b3 ARM64EC: Rethrow exceptions from within the JIT

handlers.

Billy Laws 1059279d5d ARM64EC: Handle calls into ARM64EC code with an 8-byte-aligned SP
ARM64 requires that SP is always 16-byte aligned for memory accesses,
but ARM64EC shares the SP between x64 code and ARM64 code, the former
of which doesn't enforce such a restriction. This causes crashes in
programs such as HITMAN 3 that don't correctly follow the Windows ABI
and call into system library functions with SP only 8-byte-aligned.
Fixup stack alignment in such cases by leaving the 8-byte return
address on the stack and returning to a lone 'ret' instruction instead.

code.

Fixes a minor precision issue that was reported in #2995. We still don't
return correct values for overflow. x86 always returns maximum negative
int32_t on overflow, ARM will return maximum negative or positive
depending on sign of the double.

Ryan Houdek b3a7a973a1 AVX128: Extends 32-bit indexes path for 128-bit operations
The codepath from #3826 was only targeting 256-bit sized operations.
This missed the vpgatherdq/vgatherdpd 128-bit operations. By extending
the codepath to understand 128-bit operations, we now hit these
instruction variants.

With this PR, we now have SVE128 codepaths that handle ALL variants of
x86 gather instructions! There are zero ASIMD fallbacks used in this
case!

Of course depending on the instruction, the performance still leaves a
lot to be desired, and there is no way to emulate x86 TSO behaviour
without an ASIMD fallback, which we will likely need to add as a
fallback at some point.

Ryan Houdek 4afbfcae17 AVX128: Optimize the vpgatherdd/vgatherdps cases that would fall back to ASIMD
With the introduction of the wide gathers in #3828 this has opened new
avenues for optimizing these cases that would typically fall back to
ASIMD. In the cases that 32-bit SVE scaling doesn't fit, we can instead
sign extend the elements in to double-width address registers.

This then feeds naturally in to the SVE path even though we end up
needing to allocate 512-bits worth of address registers. This ends up
being significantly better than the ASIMD path still.

Relies on #3828 to be merged first
Fixes #3829

Ryan Houdek ec7c8fd922 AVX128: Optimize QPS/QD variant of gather loads!
SVE has a special version of their gather instruction that gets similar
behaviour to x86's VGATHERQPS/VPGATHERQD instructions.

The quirk of these instructions that the previous SVE implementation
didn't handle and required ASIMD fallback, was that most gather
instructions require the data element size and address element size to
match. This x86 instruction uses a 64-bit address size while loading 32-bit
elements. This matches this specific variant of the SVE instruction, but
the data is zero-extended once loaded, requiring us to shuffle the data
after it is loaded.

This isn't the worst but the implementation is different enough that
stuffing it in to the other gather load will cause headaches.

Basically gets 32 instruction variants to use the SVE version!

Ryan Houdek 62cec7b6b2 Arm64: Remove one move if possible in FMA operations
If the destination isn't any of the incoming sources then we can avoid

in #3794, but doesn't solve the entire problem.

To solve the other half of the moving problem means we need to solve the
SRA allocation problem for this temporary register with addsub/subadd, so it gets allocated
for both the FMA operation and the XOR operation.

Ryan Houdek df40515087 AVX128: Extend 32-bit address indices when possible
When loading 256-bits of data with only 128-bits of address indices, we
can sign extend the source indices to be 64-bit. Thus falling down the
ideal path for SVE where each 128-bit lane is loading the data to
addresses in a 1:1 element ratio.

This means we use the SVE path more often because of this.

Based on top of #3825 because the prescaling behaviour was introduced
there. This implements its own prescaling when the sign extension occurs
because ARM's SSHLL{,2} instruction gives us that for free.

This additionally fixes a bug where we were accidentally loading the top
128-bit half of the addresses for gathers when it was unnecessary, and
on the AVX256 side it was duplicating and doing some additional work
when it shouldn't have.

It'll be good to walk the commits when looking at this one, as there are
a couple of incremental changes that are easier to follow that way.

If the host supports SVE128, if the address element size and data size is 64-bit, and the scale is not one of the two that is supported by SVE; Then prescale the addresses.
64-bit address overflow masks the top bits so is well defined that we
can scale the vector elements and still execute the SVE code path in
that case. Removing the ASIMD code paths from a lot of gathers.
