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.

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.

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

38a90882a4 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.

17b29d8865 WaitSynch: Removed unused variables and reduced SharedPtr copies.

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.

ed210c32b3 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
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
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.

Removed the APT Shared Font hack as it is no longer needed.

18c1c39d5e SVC: Advance time when calling GetSystemTick to escape busy-wait loops
Cubic Ninja waited for the frame to end by spinning on a loop calling
GetSystemTick while doing nothing else. Since GetSystemTick doesn't
cause a reschedule (which advances time), this meant that very little
emulated time would pass inside that loop, causing the game to spend
most of the frame burning away CPU.
