* Implement both RawSPU and threaded SPU page fault recovery
* Guard page_fault_notification_entries access with a mutex
* Add missing lock in sys_ppu_thread_recover_page_fault/get_page_fault_context
* Fix EINVAL check in sys_ppu_thread_recover_page_fault, previously when the event was not found begin() was erased and
CELL_OK was returned.
* Fixed page fault recovery waiting logic:
- Do not rely on a single thread_ctrl notification (unsafe)
- Avoided a race where ::awake(ppu) can be called before ::sleep(ppu) therefore nop-ing out the notification
* Avoid inconsistencies with vm flags on page fault cause detection
* Fix sys_mmapper_enable_page_fault_notification EBUSY check
from RE it's allowed to register the same queue twice (on a different area) but not to enable page fault notifications twice
TODO: From hw testing, it seems like sys_memory_get_page_attribute and sys_rsx_context_iomap check page size a little differently
get_page_attribute() always go by area flags, sys_rsx_context_iomap checks page by the page granularity
This means that if the area page size 64k, but shared memory is mapped with SYS_MEMORY_GRANULARITY_1M
It can be mapped for rsxio, but the page attribute will indicate 64k page size :thonk:
rsxio memory is verified to need 1m pages.
- From RE, only protocols SYS_SYNC_FIFO and SYS_SYNC_PRIORITY are valid
- Use conditional atomic op store in a few places
- Properly revert changes in sys_event_flag_set when aomic op fails
* Fix 0 vm page flags to behave like 1m flags, follows c8a681e60
* check if address exists and valid for rsx io allcations (must be allocated on 1m pages)
Is a memory manager for ASMJIT, replaces asmjit::JitRuntime
Unified memory manager for ASMJIT and LLVM
Unified SPU trampoline generation
Remove previous workarounds
Allow parallel compilation of SPU code, both at startup and runtime
Remove 'SPU Shared Runtime' option (it became obsolete)
Refactor spu_runtime class (now is common for ASMJIT and LLVM)
Implement SPU ubertrampoline generation in raw assembly (LLVM)
Minor improvement of balanced_wait_until<> and balanced_awaken<>
Make JIT MemoryManager2 shared (global)
Fix wrong assertion in cond_variable
* Fix SPU LR event setting in atomic commands according to hw test
* MFC: increment timestamp for PUT cmd in non-tsx path
* MFC: fix reservation lost test on non-tsx path in regard to the lock bit
* Reservation notification moved out of writer_lock scope to reduce its lifetime
* Use passive_lock/unlock in ppu atomic inctrustions to reduce redundancy
* Lock only once for dma transfers (non-TSX)
* Don't use RDTSC in reservation update logic
* Remove MFC cmd args passing to process_mfc_cmd
* Reorder check_state cpu_flag::memory check for faster unlocking
* Specialization for 128-byte data copy in SPU dma transfers
* Implement memory range locks and isolate PPU and SPU passive lock logic
