* Removed wrong code in sys_spu_thread_group_terminate.
* SPU Thread ID is accurate, including 5th thread id "rule".
* Fixed possible use-after-free access of spu_thread::group member.
* RawSPU ID management simplified.
* allow sys_rsx_device_map to be called twice: in this case the DEVICE address retrived from the previous call returned
* Add ENOMEM checks for sys_rsx_memory_allocate and sys_rsx_context_allocate
* add EINVAL check for sys_rsx_context_allocate if memory handle is not found
* Separate sys_rsx_device_map allocation from sys_rsx_context_allocate's
* Implement sys_rsx_memory_free; used by cellGcmInit upon failure
* Added context_id checks
* Throw if sys_rsx_context_allocate was called twice.
* Use Linux timers for sleeps up to 1ms (v3)
The current sleep timer implementation basically offers two variants. Either
wait the specified time exactly with a condition variable (as host) or use a
combination of it with a thread yielding busy loop afterwards (usleep timer).
While the second one is very precise it consumes CPU loops for each wait call
below 50us. Games like Bomberman Ultra spam 30us waits and the emulator hogs
low power CPUs. Switching to host mode reduces CPU consumption but gives a
~50us penalty for each wait call. Thus extending all sleeps by a factor of
more than two.
The following bugfix tries to improve the system timer for Linux by using
Linux native timers for small wait calls below 1ms. This has two effects.
- Host wait setting has much less wait overhead
- usleep wait setting produces lower CPU overhead
* sys_cond fixes
sys_cond_wait is now signaled atomically (regression fix)
Fix a corner case with sys_cond_wait and sys_cond_destroy EBSUY check (waiter count was inaccurate if thread is not the owner of mutex)
Add not about EBUSY corner case (TODO)
* Fix inconcistency in sys_cond_destroy and ETIMEDOUT
.. event at sys_cond_wait regarding waiters count.
Now waiters count is properly connected to the mutex owner actions after ETIMEDOUT in sys_cond_wait.
Possibly fixes sys_fs_rmdir and other cases of directory removal.
Make sure the directory with deleted files always becomes empty.
For this purpose, temp files are moved to the root of the device.
