FEXCore/DiskCache: Prune old entries automatically
 2026-09-25 15:18:34 -07:00
Ryan Houdek dd63548cb1 Windows: On unimplemented print a log 
Makes it easier to find which one was missing. Can't use regular log
routines in the header due to conflicting win32 defines.

Ryan Houdek 7962f40065 FileUtils: Implement RecursiveRemoveDirectory and WalkDirectory with NT syscalls 
A bit messy but it basically duplicates the Linux side. We don't have a
way to include NT internal defines in to FEXCore currently so the two
required symbols are just forward declared.

Ryan Houdek f3b0b41254 Win32: Implement RemoveDirectory 2026-09-25 14:39:55 -07:00
Ryan Houdek 47557a6184 FEXCore/DiskCache: Prune old entries automatically 
Adds a config option to disable pruning if desired.

Had to change FEXCore::HostFeatures slightly to remove the HostType from
the Hash for caching, as we don't want the bucket to inadvertently
delete wow64,arm64ec,linux buckets when executing in the same namespace.

Minor changes to the DiskCache::Init code to handle returning two
values, moving the HostType to be a part of the "ProcessBucketHash"
instead of the "MachineBucketHash".

Then uses the directory walking function added in the previous commit to
find mismatched/old "MachineBucketHash" directories and remove them.

Ryan Houdek 47bc73575e FEXCore/FileUtils: Adds a way to walk a directory with callback 
We need to walk a directory calling back to the DiskCache, but without
recursion.

Also fixes a function signature issue on win32.

DiskCache: adjust key strategy
 2026-09-24 11:55:40 -07:00
Pierre-Loup A. Griffais b37aae728f DiskCache: adjust key strategy 
The base directory is now the machine bucket, which is everything that affects
codegen that you can ask FEX about offline: FEX compiler version, host features.

The DB files now carry a process bucket, which is everything else that can
affect codegen, on the user/process side: 32-bitness and config.

Both together are still the bucket hash that gets laced into every lookup key,
so we still won't load mismatching code because a file is in the wrong spot.

Ryan Houdek ae3a4ae197 FEXCore: Adds a utility function for deleting a directory 
We can't use std::filesystem::remove_all on FEX Linux, so reimplement
it. No unittest for this because....That's spicy on the CI NAND.

FEXCore: Have ThreadRemoveCodeEntry IR op jump to dispatcher

Ryan Houdek 4b418a81aa FEXCore: Have ThreadRemoveCodeEntry IR op jump to dispatcher 
In order to reuse code buffers, when invalidating we will no longer be
able to invalidate code while inside the code we are invalidating.

Changes the IR operation to be a block ender itself and control jumping
to the new RIP. This way it can invalidate from the dispatcher and just
restart JIT execution.

FEXCore: Have the Syscall IR op jump to the dispatcher

Ryan Houdek 229151f878 FEXCore: Have the Syscall IR op jump to the dispatcher 
Have it treated as a block terminator IR and instead of doing
syscall+exitfunction, just do syscall and jump in to the dispatcher.

This is necessary for code invalidation and reuse for code that is stuck
in long running syscalls. We'll need to do something similar for thunks
later, although the recursive nature of thunk+callback can make that a
little squirrely.

A couple JITSymbol fixes
 2026-09-18 22:44:37 -04:00
Ryan Houdek a0ba36eb1b SharedCodeBuffer: Skip VMA naming when JITSymbols are enabled 
For some reason `perf top` prefers VMA names over perf symbols. So
disable them when any JIT symbol option is enabled. Breaks WTF tracking
for those buffers but because it's debug, we kind of have to.

May reserve a tiny area for small blocks in general, but will also be useful
for LuaJIT in anon-diskless mode.
