Subv 013778aa21 Qt: Update the WaitTree widget to show info about the current mutex of each thread. 2018-04-20 21:04:34 -05:00

Subv 5fdfbfe25a Kernel: Remove old and unused Mutex code. 2018-04-20 21:04:32 -05:00
Subv b18ccf9399 Kernel: Properly implemented svcWaitProcessWideKey and svcSignalProcessWideKey
They work in tandem with guest code to provide synchronization primitives along with svcArbitrateLock/Unlock
2018-04-20 21:04:27 -05:00
Subv e81a2080eb 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 8432749db7 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.

Yuri Kunde Schlesner 84c497292a Service: Add new ServiceFramework framework for writing HLE services
The old "Interface" class had a few problems such as using free
functions (Which didn't allow you to write the service handler as if it
were a regular class.) which weren't very extensible. (Only received one
parameter with a pointer to the Interface object.)

The new ServiceFramework aims to solve these problems by working with
member functions and passing a generic context struct as parameter. This
struct can be extended in the future without having to update all
existing service implementations.

Subv 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.
