Ryan Houdek 87b3d50899 Linux: Fixes open syscall emulated path handling 
open is rarely used compared to openat and openat2, so this has been
just missed but nothing really got upset about it.

Fixes Proton Experimental while running under pressure-vessel.

Syscalls: Fixes clone3 stack pointer
 2022-05-20 02:46:05 -07:00
Ryan Houdek d28ccc59ac Syscalls: Fixes clone3 stack pointer 
clone2 stack pointer passed in points to the highest address for the
stack.

clone3 switches this around and gives us a base pointer and a size.

glibc started using clone3 for its thread cloning which finally caught
this bug. Necessary to run any application under the Ubuntu 22.04 rootfs
since that uses a new enough glibc to encounter this.

Ryan Houdek c79d79e08b TestHarnessRunner: Use guest mapper for test harness files

Ryan Houdek 753d0ede6c FEXCore: Reclaimable thread pool allocator 
Creates a pool allocator for OpcodeDispatcher and IRCompaction that
shares memory allocations between threads in a pool and supports
reclaiming stale allocations from participating threads.

A thread will use a heuristic to keep its claimed memory allocation
around if it is allocating a lot of code. If it slows down then it will
start putting the memory allocation back in to the thread pool.

Additionally if the allocation has been "disowned" and gone to sleep
while still retaining the allocation, then another thread can inspect
 these stale allocations and reclaim it from the idling thread. Saving
further memory.

This needs some more work and cleanup but this is an interesting concept
that saves a decent amount of memory even in a basic test.

Causes teeworlds' title screen to go from 754MB to 599MB in my simple
test. 79.4% the memory usage is a good start.

Ryan Houdek f6a74a710d FEXBash: Set PS1 to make it more obvious when running under FEX 
This requires us to pass in --no-rc to bash since otherwise PS1 gets
overwritten by shell variables and nothing happens.

Which this is fine for the common use case of just wanting to run a
basic bash script under emulation.

Ryan Houdek 72e82d0304 Linux: Fixes 32-bit mmap 
This went unnoticed for so long since most applications are new enough
to use mmap2 instead of mmap.
This was just completely broken.

Ryan Houdek 52292e5f7e Linux: Fixes MAP_32BIT supported range 
I accidentally committed a 32-bit range that was significantly smaller
than what it should be.
While the minimal range worked for simple cases, it didn't work for
anything complex.
Give it the full range it needs.

Fixes #1600
