2017-05-24Kernel: Centralize error definitions in errors.hYuri Kunde Schlesner
2017-01-11Threads: Check the process' resource limit for the max allowed priority when ↵Subv
creating a thread and remove the priority clamping code.
2017-01-11Thread: Added priority range checking to svcSetThreadPriority and removed ↵Subv
priority clamping code from Thread::SetPriority.

Don't yield execution in SleepThread(0) if there are no available threads to run
2017-01-06Merge pull request #2408 from Subv/priority_boostingbunnei
Kernel: Removed the priority boost code for starved threads.
2017-01-05Kernel: Don't attempt to yield execution in SleepThread(0) if there are no ↵Subv
available threads to run. With this we avoid an useless temporary deschedule of the current thread.
2017-01-05Kernel: Remove some unused functions.Subv
2017-01-05Kernel: Removed the priority boost code for starved threads.Subv
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.
2017-01-05Kernel: Add some asserts to enforce the invariants in the scheduler.Subv
2017-01-05Kernel: Remove Thread::wait_objects_index and use wait_objects to hold all ↵Subv
the objects that a thread is waiting on.
2017-01-04Kernel: Use different thread statuses when a thread calls ↵Subv
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.
2017-01-04Kernel/Mutex: Propagate thread priority changes to other threads inheriting ↵Subv
the priority via mutexes
2017-01-04Kernel/Mutex: Implemented priority inheritance.Subv
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.
2017-01-04Kernel: Object ShouldWait and Acquire calls now take a thread as a parameter.Subv
This will be useful when implementing mutex priority inheritance.

2016-12-17Thread: remove the thread from the thread list when exitingwwylele
2016-12-10Properly remove a thread from its wait_objects' waitlist when it is awoken ↵Subv
by a timeout.
2016-12-03Threading: Reworked the way our scheduler works.Subv
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.

This makes clang-format useful on those. Also add a bunch of forgotten transitive includes, which otherwise prevented compilation.

Kernel/Threads: Dynamically allocate the TLS region for threads.
2016-05-07Kernel/Threads: Dynamically allocate the TLS region for threads in the BASE ↵Subv
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.

This shouldn't be directly exposed if there's already a partial API that operates on it. We can just provide the rest of that API.

2015-07-17Ensure all kernel objects are released during shutdownYuri Kunde Schlesner
This commit fixes several kernel object leaks. The most severe of them was threads not being removed from the private handle table used for CoreTiming events. This resulted in Threads never being released, which in turn held references to Process, causing CodeSets to never be freed when loading other applications.
