Eladash fcbeb2fa22 Remove slow vm::writer_lock usage from SPUThread.cpp 2022-05-04 23:36:57 +03:00
Nekotekina 5c1f79ab26 vm: remove g_mutex, use g_range_lock instead 
Simplification and performance improvements.
 2022-05-02 10:29:28 +03:00
Nekotekina 12c83b340d Remove built_function 
With today's branch prediction techniques, it's hardly useful.

Nekotekina 580bd2b25e Initial Linux Aarch64 support 
* Update asmjit dependency (aarch64 branch)
* Disable USE_DISCORD_RPC by default
* Dump some JIT objects in rpcs3 cache dir
* Add SIGILL handler for all platforms
* Fix resetting zeroing denormals in thread pool
* Refactor most v128:: utils into global gv_** functions
* Refactor PPU interpreter (incomplete), remove "precise"
* - Instruction specializations with multiple accuracy flags
* - Adjust calling convention for speed
* - Removed precise/fast setting, replaced with static
* - Started refactoring interpreters for building at runtime JIT
*   (I got tired of poor compiler optimizations)
* - Expose some accuracy settings (SAT, NJ, VNAN, FPCC)
* - Add exec_bytes PPU thread variable (akin to cycle count)
* PPU LLVM: fix VCTUXS+VCTSXS instruction NaN results
* SPU interpreter: remove "precise" for now (extremely non-portable)
* - As with PPU, settings changed to static/dynamic for interpreters.
* - Precise options will be implemented later
* Fix termination after fatal error dialog

Eladash 50ad7ba1f6 vm: Fix vm::unmap 
* Make vm::unmap atomic, squash the memory unmapping process inside this function while still using the same VM mutex ownership.
* Make vm::unmap not fail due to random vm::get calls, shared_ptr reference count is no longer a condition.
* Fix sys_mmapper_free_address spuriously failing with EBUSY due to random vm::get calls.
* Fix sys_vm_unmap race condition due to non-atomic vm::unmap.
* Add an optional verification block ptr arg to vm::unmap, used by patches.

Eladash 2d9929059f
vm: Fix an overflow at vm::alloc, fix vm::find_map (#10760) 
* The statement addr += align could have overflowed resulting in either infinite loop or allocating memory outside of the region (illegal).
Add a check checking if it's the last iteration of the loop, then break without adding.

* vm::find_map condition didn't consider the size of the map to be allocated, allowing illegal occupation of [<=0xB000'0000]-0xCFFF'FFFF. (0xC000'0000-0xCFFF'FFFF is reserved for RSX)
