Subv f2f2572fed Thread: Added priority range checking to svcSetThreadPriority and removed priority clamping code from Thread::SetPriority. 2017-01-11 16:38:04 -05:00

Subv 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.

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.

Subv 4251eb26ec Kernel/Semaphore: Fixed a regression in semaphore waits.

Subv 7f1dca8cd2 Kernel: Remove a thread from all of its waiting objects' waiting_threads list when it is awoken.

Subv 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
Subv 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.

Subv b6a0355568 Kernel/Mutex: Update a mutex priority when a thread stops waiting on it. 2017-01-04 15:58:47 -05:00
Subv 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.

Subv e6a7723f2f Kernel: Object ShouldWait and Acquire calls now take a thread as a parameter.

Subv bdad00c73f Threading: Added some utility functions and const correctness. 2016-12-04 09:58:36 -05:00
Subv 8634b8cb83 Threading: Reworked the way our scheduler works.
Threads will now be awakened when the objects they're waiting on are signaled, instead of repeating the WaitSynchronization call every now and then.

The scheduler is now called once after every SVC call, and once after a thread is awakened from sleep by its timeout callback.

This new implementation is based off reverse-engineering of the real kernel.

See https://gist.github.com/Subv/02f29bd9f1e5deb7aceea1e8f019c8f4 for a more detailed description of how the real kernel handles rescheduling.

Subv 2eceee3a4c Fixed the rebase mistakes. 2016-11-30 23:28:31 -05:00
Subv 009b15b3aa A bit of a redesign.
Sessions and Ports are now detached from each other.
HLE services are handled by means of a SessionRequestHandler class, Interface now inherits from this class.
The File and Directory classes are no longer kernel objects, but SessionRequestHandlers instead, bound to a ServerSession when requested.
File::OpenLinkFile now creates a new session pair and binds the File instance to it.

Subv c5e7e0fa26 IPC/HLE: Associate the ClientSessions with their parent port's HLE interface if it exists.

Subv c19afd2118 Kernel/HLE: Service::Interface no longer inherits from any Kernel object, and is now its own standalone class.
Interface is now used by aggregation in ClientPort, to forward service commands to their HLE implementation if needed.

Subv 0a33d915f8 fixup! Kernel/IPC: Use Ports and Sessions as the fundamental building block of Inter Process Communication. 2016-11-30 23:02:06 -05:00
Subv 073653e858 Kernel/IPC: Use Ports and Sessions as the fundamental building block of Inter Process Communication.
All handles obtained via srv::GetServiceHandle or svcConnectToPort are references to ClientSessions.
Service modules will wait on the counterpart of those ClientSessions (Called ServerSessions) using svcReplyAndReceive or svcWaitSynchronization[1|N], and will be awoken when a SyncRequest is performed.

HLE Interfaces are now ClientPorts which override the HandleSyncRequest virtual member function to perform command handling immediately.
