Subv 329bec6dbd Kernel: Implemented mutex priority inheritance.
Verified with a hwtest and implemented based on reverse engineering.

Thread A's priority will get bumped to the highest priority among all the threads that are waiting for a mutex that A holds.
Once A releases the mutex and ownership is transferred to B, A's priority will return to normal and B's priority will be bumped.

Subv f5a2b1920b Kernel: Remove unused ConditionVariable class. 2018-04-20 21:04:33 -05:00
Subv e499b48f97 Kernel: Remove old and unused Mutex code. 2018-04-20 21:04:32 -05:00
Subv 4e47dd5b59 Kernel: Corrected the implementation of svcArbitrateLock and svcArbitrateUnlock.
Switch mutexes are no longer kernel objects, they are managed in userland and only use the kernel to handle the contention case.
Mutex addresses store a special flag value (0x40000000) to notify the guest code that there are still some threads waiting for the mutex to be released. This flag is updated when a thread calls ArbitrateUnlock.

TODO:
* Fix svcWaitProcessWideKey
* Fix svcSignalProcessWideKey
* Remove the Mutex class.

Subv fbb0ef851c Kernel/IPC: Add a small delay after each SyncRequest to prevent thread starvation.
Ported from citra PR #3091

The delay specified here is from a Nintendo 3DS, and should be measured in a Nintendo Switch.

This change is enough to prevent Puyo Puyo Tetris's main thread starvation.

This is kinda crufty, but we need it for now to update guest state variables.

Kernel/Threads: When putting a thread to wait, specify a function to execute when it is awoken

Subv a0054d695e Kernel/Threads: When putting a thread to wait, specify a function to execute when it is awoken.
This change makes for a clearer (less confusing) path of execution in the scheduler, now the code to execute when a thread awakes is closer to the code that puts the thread to sleep (WaitSynch1, WaitSynchN). It also allows us to implement the special wake up behavior of ReplyAndReceive without hacking up WaitObject::WakeupAllWaitingThreads.

If savestates are desired in the future, we can change this implementation to one similar to the CoreTiming event system, where we first register the callback functions at startup and assign their identifiers to the Thread callback variable instead of directly assigning a lambda to the wake up callback variable.

Subv 2e78c05d91 Kernel/Thread: Allow specifying which process a thread belongs to when creating it.
Don't automatically assume that Thread::Create will only be called when the parent process is currently scheduled. This assumption will be broken when applets or system modules are loaded.

Subv 9200465e55 Kernel/Threads: Don't clear the CPU instruction cache when performing a context switch from an idle thread into a thread in the same process.
We were unnecessarily clearing the cache when going from Process A -> Idle -> Process A, this caused extreme performance regressions.

Subv 23ad87098d Kernel/Memory: Switch the current page table when a new process is scheduled. 2017-09-10 15:14:31 -05:00
Subv 733dfe220e Kernel/Threads: Don't immediately switch to the new main thread when loading a new process.
This is necessary for loading multiple processes at the same time.
The main thread will be automatically scheduled when necessary once the scheduler runs.
