Ryan Houdek 2291c5b230 OpcodeDispatcher/Vector: Make sure MXCSR is masked 
We don't support the exception bits, make sure these are masked off so
spurious exception checks don't break.
 2026-03-28 17:47:55 -07:00
Ryan Houdek f78e194cf7 Linux/GuestFrames: Ensure MXCSR is saved and restored on signal 
This was causing an unfortunate set of circumstances where Dark Souls
III was modifying MXCSR and we weren't saving it, cause the value to change
from 0x9fc0 to 0.

This "enabled" float exceptions by unmasking the exception masks in
MXCSR. This in turn had Dark Souls III's `expf` function to fault out,
as it checks if the MXCSR exception masks are set or not for determining
if underflow should assert or not.

Wow64/arm64ec has a similar problem where it always sets back to default
on signal. Which means game lose DAZ, but I'm not fixing that bug right
now.

Fixes #5391

Ryan Houdek f0854a16fe Allocators: Remove legacy NOREPLACE handling 
We needed this handling on old kernels that didn't understand the
NOREPLACE flag. We no longer support kernels this old, so remove some of
this vestigial code.

Lioncache b9c0af7c3b CPUID: Add basic handling for AVX10 info 
Just gets the feature bit handling stuff in place for various
facilities, so it can be easily expanded in the future.

Tony Wasserka a1aa1658ec LinuxSyscalls: Re-open file descriptors for parsing ELF headers 
File descriptors returned by dup() share state with the original FD, so we
need to use open() to create a fully independent object.

Default to a Release build, which ensures optimizations are enabled and

FEX: Disable THP on key allocations that consume memory
 2026-03-18 21:04:15 +01:00
Ryan Houdek c547b1bec3 FEX: Disable THP on key allocations that consume memory 
Disables THP on some key locations that are fairly sparse
- rpmalloc
  - This is the big one as this allocates some heavy sparse buffers.
- CallRet stacks
  - These get in the hundreds of megabytes, while not being sparse they
    trend towards only using a handful of pages and ballooning to 2MB
    per thread is quite heavy.
- Lookup cache
  - L1 specifically gets hit here which adds a decent chunk of overhead
    due to sparsity.

Win32 for all of these also aren't handled, but that will need to be a
followup.
