In some very unscientific benchmark:
spu_thread::do_dma_transfer() was taking 2.27% of my CPU before, now
0.07%, while __memmove_avx_unaligned_erms() was taking 1.47% and now
2.88%, which added makes about 0.8% saved.
I saw stvx v128{0} (aligned 16-bytes store) usage on the first 16-bytes of CellSaveDataCBResult before funcStat in fw.
Also I saw 4 stw of u32{0} on it as well before funcFile, funcFixed and funcList.
So just add the resets for result before all callbacks, and make all
members of savedata_ontext 16 -byte aligned in case there are more
members guaranteed to be aligned.
* Always memset 0 setBuf->buf (to bufSize) before funcStat if the direcory is not new.
* Always memset 0 setBuf->buf (to bufSize) if listGet->dirNum became non-zero (listGet->dirListNum can be zero yet memset still occurs) .
* Clear traces of setList setup before funcStat (after funcFixed/List, only if listGet->dirNum != 0, callback can hack this value and prevent the memset).
- Use native FMA to emulate VMADDFP, with a fallback for processors that don't support FMA
- Use native FMA to emulate VNMSUBFP as well, but note that it differs from the emulated path with regards to negative zero
'id' is not the idm id, also explicitly join the thread so a situation where the thread is still active and communicating other threads (e.g via MMIO or MFC) yet its ID is removed won't happen. (logic breakage, destroyed thread can't be active)
* Make PPU id removal after exit atomic with descheduling
* Make joining thread scheduling atomic with thread exit sleep.
* Update sys_ppu_thread_stop/restart.
* Add idm::remove_verify.
* Check listSet->fixedListNum.
* Check listSet->fixedList for nullptr and its directory items names.
* Check listSet->focusDirName for nullptr and directory name.
* Check listSet->newData->iconPosition.
* Check listSet->newData->dirName for nullptr and directory string.
* Check statSet->setParam->parental_level for old sdk.
* Return an error if listSet->focusPosition is NEWDATA and listSet->newData is nullptr.
* Simplify savedata directory list selection.
* Allow '_' at filenames start and extension.
* Check if reading offset is valid, fix error code to CELL_SAVEDATA_ERROR_FAILURE.
* Don't create empty file on error of write ops.
* Don't allow "." and ".." filenames on funcFile, return CELL_SAVEDATA_ERROR_BROKEN.
Use -fno-exceptions in cmake.
On MSVC, enable _HAS_EXCEPTION=0.
Cleanup throw/catch from the source.
Create yaml.cpp enclave because it needs exception to work.
Disable thread_local optimizations in logs.cpp (TODO).
Implement cpu_counter for cpu_threads (moved globals).
- 'Auto' is not an actual aspect ratio, just a dont-care flag to set the
display to the best fit aspect ratio.
Decay this option into a proper ratio for cellVideoOutGetState to
return legal values.
- Avoids a situation where a game configures output correctly but gets back bogus information later when querying.
- Should fix games being broken at some resolutions but not others.
* Initial GHLtar emulation
* Add GHLtar to CMakeLists and VS project, zero the buffer and remove unused header values
* Fix coding style issues and include headers
* Remove redundant if, improve code formatting
* Remove needless includes

* Improve sys_timer_get_information
* sys_timer_disconnect_event_queue sets STATE_STOP regardless of port connection status.
* sys_timer_get_information sets 0 for period and next_expire if the timer is stopped.
* Fix two minor races in lv2_timer thread
* If the timer thread is about to fire an event of queue x, then another thread disconnects the queue, then restarts the timer and connects the event queue, then the timer thread sends an event - event data combination (source, data1, data2, next) may be inaccurate.
* If the timer thread is about to send an event (periodically), then another thread stops the timer and starts it again with sys_timer_start_periodic_absolute, timer.expire in info->timer_state in sys_timer_get_information may be inaccurate.
* sceNpDrmVerifyUpgradeLicense(2): copied string from content_id is 47 chars in length at max, is no null term was found it forces string termiation.
* sceNpDrmIsAvailable(2): Same with drm path just that it's 256 chars at max.
