Billy Laws f6dab33190 Windows: Split out CRT/WinAPI reimplementation 
We can use the system CRT for the offline compiler, but still want to
pull in e.g. InvalidationTracker and other helpers.

esullivan 8cc967fa22 HostFeatures: Disable SupportsTSOImm9 for some CPUs 
This change avoids using the LDAPUR instruction with CPUs that are know to be
impacted by an ARM CPU errata that results in poor performance.

Ryan Houdek 6772581c53 Arm64ec: Print a log when kernel unaligned atomics are used 
Not having this in FEXInterpreter as it is too spammy in the general
case.

Ryan Houdek 387201815b Config: Add option to enable or disable kernel backpatchin on unaligned atomic 
Default to enabled because this is the config we expect by default.
In the future will get some benchmarking in various games like
Assassin's Creed, and Call of Duty.

Ryan Houdek e862c904a9 FEX: Implements support for JIT CodeBuffer guard page restart 
When the JIT CodeBuffer overflows, we will now catch accesses to the
guard page and longjump while restarting the JIT with a larger buffer
request.

Fixes #4877

Tony Wasserka 5a002ad08d Revert "Merge pull request #4969 from Sonicadvance1/rpmalloc" 
This reverts commit e1a45a2720, reversing
changes made to bd7edd8651.

The change rendered pressure-vessel non-functional on muvm-based setups
like Fedora Asahi Remix.

Ryan Houdek 63304a1d88 Windows: rpmalloc 2025-10-27 12:05:08 -07:00
Ryan Houdek 985bdf2b6c Switch over to rpmalloc instead of jemalloc. 
rpmalloc is currently very aggressively configured which causes
significant reductions in resident memory over jemalloc.

In Bayonetta's title screen it went from 963MB down to 834MB resident.

 2025-10-21 23:53:36 -04:00
Ryan Houdek 81fc502c6c FEXCore: Remove Paranoid TSO mode. 
This mode has been broken for a long time because it's mostly untested.
Barriers, and backpatching while slow have proven that they work.
Maintain the one TSO path, at least until all ARM hardware gains support for
x86-TSO memory model mode.

Ryan Houdek b40e707771 wow64/arm64ec: Call GetTLS less frequently 
If called back-to-back, the compiler can't optimize the object creation
resulting in multiple indirections. Save the creation and pass it
around, allowing the compiler to merge loadstores, and remove redundant
loads.

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.

Linux: Implement support for extended volatile metadata
 2025-09-30 20:01:26 -04:00
Ryan Houdek 1758648f56 Common: Move ApplyFEXExtendedVolatileMetadata to Common 
It is going to be used by Linux.

Also adds support for file offset handling, which is required on Linux
but not on win32.

Ryan Houdek 418ce0aed9 Wow64: Ensure extended volatile metadata is removed

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.

Ryan Houdek f050571696 Implement support for additional provided volatile metadata 
Only wired up for wow64 and arm64ec. Gives more granular control over
TSO enabling and disabling. Matches arm64ec volatile metadata except
with one more additional feature that whole modules can be disabled at a
time.

Once we know the mapped size of files in Linux then we'll be able to do
the same thing there, but there's not a full mechanism wired up for that
yet.

Ryan Houdek 25a0752e58 FEXCore: Move LDT/GDT management to the frontend 
This will allow the frontend to manage LDT and GDT so that Linux will be
able to install 32-bit code segments.

FEXCore: Split GDT and LDT prep work
 2025-08-13 12:06:41 -04:00
Ryan Houdek 3f9df49e3e FEXCore: Split GDT and LDT prep work 
Taking this very slowly because this is very fickle code. The frontend
needs to manage GDT and LDT, but before we get there, we need to
actually add support for LDT in the backend. Split the segments to two
arrays so the JIT can actually update their cached values correctly.

Still treats GDT and LDT as mirrors like how the JIT previously did (By
it ignoring the selector's TI bit).
