Pierre-Loup A. Griffais c3fb6ccaaa DiskCache: make Writer thread low-priority 2026-08-23 14:01:32 -07:00
Ryan Houdek 0717f4689b FEX: Only fsync on assert 
The rest of the messages should be buffered, no reason to sync those.

Pierre-Loup A. Griffais c038bb5794 Windows: add Thread implementation 
So we can make a worker thread that the guest (hopefully) won't see.

Pierre-Loup A. Griffais efc5eaf9c7 Utils/File: add PRead(), PWrite() and Size() 
Because PRead/PWrite don't have the same side effects on the file cursor
between Linux and Windows (:/), make them all-or-nothing.

Jacek Caban 85efb47a3b Windows: Handle interrupt 3 in HandleGuestException 2026-08-21 13:16:43 +02:00
Pierre-Loup A. Griffais 561c32b45d Disk Cache initial implementation 
Serializes code blocks to disk - only blocks coming from known regions, for now

Disabled by default, key and versioning still needs work, but works for testing

Ryan Houdek 2b0d94536f Steam/CompatTool: Become more picky about configs 
If `STEAM_COMPAT_FEX_CONFIG` is missing options, then instead of having
an opinion about what those options should be, just leave them unset.
This allows FEX's regular default option handling to kick in for missing
configuration options.

Where previously if an option was missing from the config, it would
default to boolean false, which may or may not be the default depending
on option.

Ryan Houdek b161a74365 Misc: Adds some missing headers 
Newer compiler and libraries got angry that these were missing.

Win32: Actually set app config path and name

Iaying 7629323548 Fix an XMM register bug in SpillSRA, along with adding a test that reproduces the bug 2026-08-03 15:15:41 -07:00
Ryan Houdek 681636cd68 Win32: Actually set app config path and name 
Apparently we never set this and it happened to not be a problem. I
needed it to gather some data so fix it.

Martin Storsjö efe38f2ee2 Add more function stubs for libc++ 23 on Windows 
These are needed by libc++ when targeting Windows since
https://github.com/llvm/llvm-project/commit/8a531c3608c722ad529be448d6ecef06ba107228,
which is included in libc++ 23.

In a very brief test, it seems like we don't need to actually
implement them.

Martin Storsjö 08031a2767 Add missing includes 
This fixes compilation with libc++ 23, which has removed a number
of unnecessary transitive includes in its headers.

Include <cstdlib> in StringConv.h for std::strtoll and std::strtoull.

Include <cstdlib> for the declarations of malloc/free/realloc/calloc
in Alloc.cpp. (Without this, the functions we define end up with
C++ name mangling.)

Include <stdarg.h> in IO.cpp for va_start/va_end.

SignalDelegator: Remove unused Required parameter in handler setting
 2026-07-27 13:14:14 -07:00
LC e8b5cd18bd SignalDelegator: Remove unused Required parameter in handler setting 
The required flag is set by the subsequent frontend functions that
follow the calls to these functions.

LC 1a77f41846 Config: Add missing override specifier 2026-07-27 14:01:11 -04:00
LC d1947f715c Config: Move strings in constructor where applicable 
Same thing, just a little less memory churn.
 2026-07-27 14:00:06 -04:00
LC 3f7971b7d2 Config: Mark internally linked where applicable 
Makes it obvious these aren't supposed to be exposed.
 2026-07-27 13:56:53 -04:00
LC 2cbd5cb3e6 Config: Amend prototypes where applicable 
Previously, these didn't match up with the implementation (luckily it's
only used internally at the moment).

LC 331655182d ThreadManager: Fix error return values in FrontendAllocateSlots() 
If ftruncate or the mmap ever fail for whatever reason, then we need to
return the current size, rather than the new size.

SignalDelegator: Group members together
 2026-07-19 16:13:26 -07:00
LC 3959863462 SignalDelegator: Group members together 
Hides all public members and situates all of them together to make for
an easier overview.
 2026-07-19 21:10:35 -04:00
LC 6e37dca566 LinuxAllocator: Reduce MemAllocator32Bit size by 16 bytes 
These constants don't need to be member vars.
 2026-07-19 18:37:38 -04:00
LC a3d0b67777 LinuxEmulation: Resolve missing prototype warnings 
Ensures all functions are marked whether they're intended to be
internally linked or not.

VDSO_Emulation: Mark relevant members as internally linked
 2026-07-16 12:34:27 -07:00
LC a4d5fbae63 HostRunner: Tidy up interface 
We've accumulated a bunch of forward declarations that are no longer
necessary. We also don't need to pass the signal delegator as a
reference, since we're not modifying the pointer itself, it's just
passed in to register a signal handler.
 2026-07-16 07:39:03 -04:00
LC 2943b87c83 VDSO_Emulation: Mark relevant members as internally linked 
Silences missing prototype warnings and makes it obvious they're only
used within the translation unit.
 2026-07-16 07:28:50 -04:00
LC 9575506391 FEXServer: Fix some missing declaration warnings 
Makes sure prototypes are visible to their implementation. Also marks
functions internally linked where applicable.

Also makes it a little more visibly obvious which bits are exposed for
use elsewhere.
 2026-07-16 07:10:32 -04:00
LC 70eafc4f6f FEXGetConfig: Mark helpers as static where applicable 
Makes them internally linked, and also lets them be caught by the
compiler when they're unused.
 2026-07-15 12:22:12 -04:00
LC 38cbd2aeb2 FEXGetConfig: Add convenience option for dumping system/tso info 
Just lets you get a broad overview all at once instead of needing to
type out every long command.

Now it's easier to be lazy and just pass "-e", or "--all-emu-info".

Ryan Houdek 372891361c HostFeatures: Pull MMFR3 identification register

LC 23402bf31b x32/Semaphore: Fix storing of message type in msgrcv 
This was previously storing into the local compat handler, not the
actual managed message.
 2026-07-13 17:30:27 -04:00
LC 50be718b72 x32/Semaphore: Mark _ipc as static 
This isn't used outside of the translation unit.
