fc2266130b Kernel: Don't attempt to yield execution in SleepThread(0) if there are no available threads to run. 
With this we avoid an useless temporary deschedule of the current thread.

933df2606a Kernel: Removed the priority boost code for starved threads. 
After hwtesting and reverse engineering the kernel, it was found that the CTROS scheduler performs no priority boosting for threads like this, although some other forms of scheduling priority-starved threads might take place.

For example, it was found that hardware interrupts might cause low-priority threads to run if the CPU is preempted in the middle of an SVC handler that deschedules the current (high priority) thread before scheduling it again.

4251eb26ec Kernel/Semaphore: Fixed a regression in semaphore waits. 
The regression was caused by a missing check in #2260.

The new behavior is consistent with the real kernel.

7f1dca8cd2 Kernel: Remove a thread from all of its waiting objects' waiting_threads list when it is awoken. 
This fixes a potential bug where threads would not get removed from said list if they awoke after waiting with WaitSynchronizationN with wait_all = false

fd95b6ee26 Kernel: Remove Thread::wait_objects_index and use wait_objects to hold all the objects that a thread is waiting on. 2017-01-05 09:40:14 -05:00

cef5f45de2 Kernel: Use different thread statuses when a thread calls WaitSynchronization1 and WaitSynchronizationN with wait_all = true. 
This commit removes the overly general THREADSTATUS_WAIT_SYNCH and replaces it with two more granular statuses:

THREADSTATUS_WAIT_SYNCH_ANY when a thread waits on objects via WaitSynchronization1 or WaitSynchronizationN with wait_all = false.

THREADSTATUS_WAIT_SYNCH_ALL when a thread waits on objects via WaitSynchronizationN with wait_all = true.

7abf185390 Kernel/Mutex: Implemented priority inheritance. 
The implementation is based on reverse engineering of the 3DS's kernel.

A mutex holder's priority will be temporarily boosted to the best priority among any threads that want to acquire any of its held mutexes.
When the holder releases the mutex, it's priority will be boosted to the best priority among the threads that want to acquire any of its remaining held mutexes.

e6a7723f2f Kernel: Object ShouldWait and Acquire calls now take a thread as a parameter. 
This will be useful when implementing mutex priority inheritance.

38a90882a4 Kernel/Synch: Do not attempt a reschedule on every syscall. 
Not all syscalls should cause reschedules, this commit attempts to remedy that, however, it still does not cover all cases.
