Tony Wasserka 02c00a87dd LinuxSyscalls: Track MappedResources only for regular files that are executable 2025-10-20 18:00:25 +02:00
Tony Wasserka 6c77bc12c1 LinuxSyscalls: Don't skip MappedResource creation on path query failure 
MarkGuestExecutableRange requires a MappedResource to be available even when
FEX doesn't do anything else with it.

Ryan Houdek 3c6246f99a SignalDelegator: Remove bool for deferring signals 
Useful while deferred signals were still a bit more fragile but I
haven't touched this in quite a while no, so just deleted.

SyscallsVMATracking: Make list management internally linked
 2025-10-13 10:54:31 -07:00
Paulo Matos 123fcd4bea Add F_ADD_SEALS and F_GET_SEALS support to 32-bit fcntl 
Fixes crash with "Unhandled fcntl64: 0x409"
Seen with steam running Bayonetta with Proton Experimental.

Ryan Houdek 474f2dc267 FEX: Name remaining allocations as "Misc" 
This captures the remaining FEX allocations that /aren't/ coming from
JEMalloc, allowing us to separate our mapped regions versus just
jemalloc allocations.

With some additional naming in jemalloc (which I'm not adding here) this
gets us interesting results:
```
        Misc resident:        54 MiB
    JEMalloc resident:        208 MiB
```

So 208MB of active jemalloc allocations in this particular case. These will be able to be tracked in heaptrack-like applications if careful.
This should let us target down whatever live allocations we're keeping
large amounts of data around if possible.

Lioncache 10835c4b62 SyscallsVMATracking: Make list management internally linked 
These don't require being bound to class state directly, and so the list
management can be completely opaque to the outside (also means less
rebuilding if these change)
 2025-10-10 15:36:46 -04:00
Lioncache 3e741df77b SyscallHandler: Avoid self-referencing global 
We don't need to indirect through the handler global inside of the class
itself for instance member functions.
 2025-10-10 15:29:29 -04:00
Lioncache 987fc925ee FileManagement: Use emplace instead of insert for set 
These are cases where the string can be directly constructed internally
instead of being copied/moved.
 2025-10-09 22:02:06 -04:00
Lioncache b6cbb23781 FileManagement: Make use of std::string_view in LoadThunkDatabase() 
Same behavior, but avoids allocating except for the case where its
necessary.

Lioncache a967976420 BPFEmitter: Simplify iterator declarations 
Makes the jump labels a little quicker to read.
 2025-10-09 00:57:49 -04:00
Lioncache 7e1e1ccccc BPFEmitter: Move private API into implementation 
Keeps some internals fully private (and also avoids dumping
some defines into other headers).
 2025-10-09 00:57:49 -04:00
Ryan Houdek 673e826e46 FEX: Remove InlineSyscall and related flags 
FEXCore no longer optimizes syscalls to be inline.

NFC, just avoids passing around a bunch of data structures for no
reason.

Ryan Houdek 3b88947cbe Merge pull request #4950 from lioncash/syscall 
SyscallHandler: Shrink definition struct from 24 to 16 bytes
 2025-10-08 14:03:57 -07:00
Lioncache 10c3b2fb5d SyscallHandler: Shrink definition struct from 24 to 16 bytes 
Just a minor space saving, given how many syscall definitions we'll
have.

Lioncache a2445904e7 ThreadManager: Make StatAlloc instance private 
This doesn't need to be public.
 2025-10-08 16:13:23 -04:00
Lioncache d94b9fae94 SourceCodeResolver: Pass string_view by value for GenerateMap() 
Generally this should be passed as a value type unless there's a good
reason not to.

Lioncache 05fcaaa758 Syscalls: Remove unimplemented prototypes 2025-10-07 01:27:11 -04:00
Ryan Houdek 2cab87fbd0 ThreadManager: Fix mmap usage to not take guest space 
SHM stats and CallRet stack was accidentally using system mmap which
means it would take VA space from the guest. Ensure it uses the
Allocator helpers so that doesn't happen.

Gives 32-bit guests 8-ish megabyte of VA space back.

Ryan Houdek b08e5f9821 Linux: Implement support for extended volatile metadata 
Allows applications running entirely under Linux to use the same
extended volatile metadata as Windows.

For example `FEX_EXTENDEDVOLATILEMETADATA=iw4sp.exe\;0xe9da0-0xe9ec7`
this configuration works for both wow64 and Linux to disable the TSO
emulation on the memcpy routine in that game that consumes around 80% of
CPU time in TSO emulation.

Works with Linux native games as well of course.

Ryan Houdek dd4f508b77 FEX: Fixes SIGILL reporting 
Two bug fixes here.
- We weren't reporting a correctl ErrorRegister. Needs to contain
  PF_INSTR at least.
- We weren't setting siginfo->si_addr in the case of `FaultToTopAndGeneratedException`

Fixes Mafia 2 (Classic)

Ryan Houdek de6d907e27 SignalDelegator: Correctly save and restore x87 state. 
We need to read the current x87 TOP location and rotate the values when
saving and restoring the context state on Linux. Wasn't visible in the
ASM tests since we read the FEX's CPU state directly there.

Ryan Houdek 85e67f92c5 FEX: Rebrand FEXInterpreter as FEX 
Still creates a copy of FEXInterpreter from FEX for downstream projects
to have some time to get off the old name. Creating a symlink is kind of
a pain in cmake so just doing an install copy is easy.

Ryan Houdek 7273041314 FEXInterpreter: Remove FEXLoader 
Doesn't /quite/ remove the ArgumentLoader because it is intertwined with
LinuxEmulation in an annoying way that will take another step to remove.

Pares the base IR header down to a modest size and also reveals a few indirect
reliances on the allocator facilities.

Lioncache 1e03219ca3 Syscalls/Thread: Add missing forward declarations

Lioncache de8b4438e3 ThreadManager: Eliminate indirect inclusions 
We had quite a bit of dependencies that were currently being indirectly relied upon.
We can forward declare the relevant ones and add the includes for the ones that are
explicit.

Lioncache ecc526a9d8 CodeLoader: Make GetApplicationArguments() return by reference 
We don't really need to make this potentially return a null pointer when we could always return a valid instance
that would just happen to be empty if unused.
