Subv 43cf36a1d2 Threads: Check the process' resource limit for the max allowed priority when creating a thread and remove the priority clamping code. 2017-01-11 16:38:05 -05:00
Subv ca538e09f2 Thread: Added priority range checking to svcSetThreadPriority and removed priority clamping code from Thread::SetPriority. 2017-01-11 16:38:04 -05:00
Subv 6834c76aaf Y2R: Use the proper error code when GetStandardCoefficient receives an invalid value. 2017-01-11 16:38:03 -05:00
Subv 9340e46590 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.

Sebastian Valle 8d3dc51f5e Merge pull request #2409 from Subv/unused_funcs 
Kernel: Remove some unused functions.

Subv cbee82c371 Kernel: Remove some unused functions. 2017-01-05 13:17:06 -05:00
Subv 0af38a0ee3 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 2ff5768bc1 Kernel: Implemented Pulse event and timers. 
Closes #1904
 2017-01-05 13:06:17 -05:00
Subv 66020871a4 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.

Subv 8d62714c87 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
 2017-01-05 09:40:15 -05:00
Subv cd9ba6b5df 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 cdca3666da 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 b67ee215dc Kernel/Mutex: Update a mutex priority when a thread stops waiting on it. 2017-01-04 15:58:47 -05:00
Subv 896e278c28 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.
 2017-01-04 15:58:46 -05:00
Subv 10e7ec47e2 Kernel: Object ShouldWait and Acquire calls now take a thread as a parameter. 
This will be useful when implementing mutex priority inheritance.
 2017-01-04 15:58:45 -05:00
Subv cb21b68ddc 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.

Subv 7214f4986e Split SessionRequestHandler::HandleSyncRequest into HandleSyncRequest, TranslateRequest and HandleSyncRequestImpl.

Subv 7e5b90a04b Threading: Added some utility functions and const correctness. 2016-12-04 09:58:36 -05:00
Subv e3486361fd 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 a15e34040a Threads do not wait for the server endpoint to call AcceptSession before returning from a ConnectToPort or GetServiceHandle call. 2016-12-01 10:47:06 -05:00
Subv 694df935a6 Fixed the rebase mistakes. 2016-11-30 23:28:31 -05:00
Subv 20f90896af 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.
 2016-11-30 23:12:35 -05:00
Subv 856f8029d7 IPC/HLE: Associate the ClientSessions with their parent port's HLE interface if it exists. 
Pass the triggering ServerSession to the HLE command handler to differentiate which session caused the request.
 2016-11-30 23:04:00 -05:00
Subv 11daab060a 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.
 2016-11-30 23:03:59 -05:00
Subv d0093a8b40 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 0d2f2880b9 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.

Subv d9baef11f2 Kernel/Threads: Dynamically allocate the TLS region for threads in the BASE region of the linear heap. 
Each thread gets a 0x200-byte area from the 0x1000-sized page, when all 8 thread slots in a single page are used up, the kernel allocates a new page to hold another 8 entries.

This is consistent with what the real kernel does.
