* Fix typo in lv2_obj::create.
* Always save ipc_key as 0 for non-shared object creations, regardless of thbe value set by creation attribute.
* Show IPC key of shared memory (sys_mmapper) memory objects in kernel explorer.
* Remove custom event queue's IPC management of favour of universal LV2 approach.
* Move ipc_manager to FXO.
* Fix ipc_manager internal storage memory leak: deallocate entry when IPC object destroyed.
* Rewrite lv2_obj::create to be simpler (remove many duplicated code).
* Always execute lv2_obj::create under both IPC and IDM mutexes at once (not in non-atomic single-steps). Fixing potential case where concurrency can cause IDM to contain 2 or more different objects with the same IPC key with SYS_SYNC_NOT_CARE (instead of the same object).
* Do not rely on smart ptr reference count to tell if the object exists. Use similar approach as event queues as it makes error checkings accurate.
* Optimize lv2_event_port by using std::shared_ptr for queue which wasn't allowed before.
* Fix a corner case where SPU thread has the same ID as a PPU thread.
* Fix a potential deadlock on Emu.Stop() while sending event in EBUSY loop.
* Thread specific notifications.
- Multiple header files where missing #includes to other headers that
where used in the header. Correct header was included in correct
order in source files which caused everything to compile.
- Added missing #includes so header files correctly include all their
dependencies and fixes problems with IDEs being unable to parse
headers correctly due to missing symbols
- Add vm_locking.h and vm_reservation.h and move relevant functions
and types to these headers.
- Change include order and make vm_ptr.h, vm_var.h and vm_ref.h headers
usable invidually and them including vm.h instead of other way around
- Because usage of vm::ptr now requires including vm_ptr.h instead of
vm.h updated multiple #includes
- Added additional #includes to vm_reservation.h and vm_locking to
where vm::reservation_* and locking related functions are used
* 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
Implement helper functions balanced_wait_until and balanced_awaken
They include new path for Windows 8.1+ (WaitOnAddress)
shared_mutex, cond_variable, cond_one, cond_x16 modified to use it
Added helper function utils::popcnt16
Replace most semaphore<> with shared_mutex
