82a355b3cd Kernel: Ensure objects are kept alive during ClientSession disconnection 
Fixes #2760

8a35f3634e Kernel: Add a dedicated SetHleHandler method to ServerPort/ServerSession 
This allows attaching a HLE handle to a ServerPort at any point after it
is created, allowing port/session creation to be generic between HLE and
regular services.

41a3feea66 HLE: Move SessionRequestHandler from Service:: to Kernel:: 
Most of the code that works with this is or will be in the kernel, so
it's a more appropriate place for it to be.

6f662625d3 Kernel: Move WaitObject to a separate file 
Now that HandleTable doesn't directly depend on WaitObject anymore, this
can be separated from the main kernel.h header.

ddbf9cec1b Kernel: Removed HandleTable::GetWaitObject 
This isn't necessary anymore since plain Get works correctly for
WaitObjects.

2668c26a68 Kernel: Map special regions according to ExHeader 
This replaces the hardcoded VRAM/DSP mappings with ones made based on
the ExHeader ARM11 Kernel caps list. While this has no visible effect
for most applications (since they use a standard set of mappings) it
does improve support for system modules and n3DS exclusives.

- Incorrect parameter referencing.
- Missing @param tags.
- Typos in @param tags.

and a few minor other issues.

6c6117868a 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.

d27ef4a5d3 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.

f8d98e241d 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.

a0ae8f7c26 Kernel: Add some asserts to enforce the invariants in the scheduler. 2017-01-05 09:40:18 -05:00

1ba3dd032e 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

3ce2c24665 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

bcad1d6f12 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.

4e6369d41d 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.

90570c153b Kernel: Object ShouldWait and Acquire calls now take a thread as a parameter. 
This will be useful when implementing mutex priority inheritance.

a1718862e3 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.
