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 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.

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).

Billy Laws 1ac3d3c5a6 Windows: Extend user handle access masks in callbacks where necessary
While most applications will just create ALL_ACCESS handles which
support the additional operations FEX needs over the regular windows syscall
(usually just QUERY_INFORMATION to lookup the thread object), it is
valid for them to pass in the minimal set required for each operation
and windows/wine will reject any other operations (e.g. querying the TEB
base on a handle with only the SUSPEND right). Windows permits
duplicating handles to extend their permissions given the process itself
has such permissions, so do that as necessary for the operations FEX
needs.

Billy Laws b2b5ccf69c Windows: Validate any user handle permissions for syscall callbacks
In the terminate case, if we don't return early then we will delete the
FEX thread object but the actual terminate call that follows will
fail, leaving the thread in a bad state.

Billy Laws 6f5d4fbf30 Windows: Avoid potential deadlocks is a thread is terminated while in the JIT
Try to suspend the thread before termination to ensure no important JIT locks
are held that could be left locked if the thread is compiling code etc.

Billy Laws 8ad1ea499d Windows: Avoid a double-free if a thread is terminated twice
Unlikely to show up in any real code, but if an attempt is made to terminate
a terminated thread we should handle this gracefully.
2025-08-12 00:51:00 +01:00
Billy Laws 4df17abea7 Windows: Avoid potential race between thread init and termination
With the prior locking, we could try to terminate a thread while it
was initializing and perhaps holding global locks leading to deadlock.

Billy Laws 972c8a97dc ARM64EC: Disable syscall callbacks when handling OvercommitTracker AVs
We don't need to be informed of our own mappings, avoids a deadlock that
occurs if the ThreadCreationMutex lifetime is extended when creating a
thread.
