2017-01-05Kernel: Remove a thread from all of its waiting objects' waiting_threads ↵Subv
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
2017-01-05Kernel: 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: Update a mutex priority when a thread stops waiting on it.Subv
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.
2017-01-04Kernel/Synch: Do not attempt a reschedule on every syscall.Subv
Not all syscalls should cause reschedules, this commit attempts to remedy that, however, it still does not cover all cases.

Threading: Reworked the way our scheduler works.

2016-12-10Properly remove a thread from its wait_objects' waitlist when it is awoken ↵Subv
by a timeout.
2016-12-09Moved the HLE command buffer translation task to ServerSession instead of ↵Subv
the HLE handler superclass.
2016-12-09WaitSynch: Removed unused variables and reduced SharedPtr copies.Subv
Define a variable with the value of the sync timeout error code. Use a boost::flat_map instead of an unordered_map to hold the equivalence of objects and wait indices in a WaitSynchN call.
2016-12-08Added a framework for partially handling Session disconnections.Subv
Further implementation will happen in a future commit. Fixes a regression.
2016-12-08Use std::move where appropriate.Subv

2016-12-06Improved the algorithm for GetHighestPriorityReadyThread.Subv
2016-12-05Return an error code when connecting to a saturated port.Subv
The error code was taken from the 3DS kernel.
2016-12-05Split SessionRequestHandler::HandleSyncRequest into HandleSyncRequest, ↵Subv
TranslateRequest and HandleSyncRequestImpl. HandleSyncRequest now takes care of calling the command buffer translate function before actually invoking the command handler for HLE services.
2016-12-05Kernel: Remove the Redirection handle type.Subv
2016-12-05KServerPorts now have an HLE handler "template", which is inherited by all ↵Subv
ServerSessions created from it.
2016-12-04Threading: Added some utility functions and const correctness.Subv
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.
2016-12-02Declare empty ServerSession and ClientSession constructors as default.Subv
2016-11-30Fixed the rebase mistakes.Subv
2016-11-30A bit of a redesign.Subv
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.
2016-11-30IPC/HLE: Associate the ClientSessions with their parent port's HLE interface ↵Subv
if it exists. Pass the triggering ServerSession to the HLE command handler to differentiate which session caused the request.
2016-11-30Kernel/HLE: Service::Interface no longer inherits from any Kernel object, ↵Subv
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.
2016-11-30fixup! Kernel/IPC: Use Ports and Sessions as the fundamental building block ↵Subv
of Inter Process Communication.
2016-11-30 Kernel/IPC: Use Ports and Sessions as the fundamental building block of ↵Subv
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.

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