From 4e6369d41d72fd4b57f136a6124dcf679ef44702 Mon Sep 17 00:00:00 2001 From: Subv Date: Sun, 1 Jan 2017 16:59:30 -0500 Subject: 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. --- src/core/hle/kernel/thread.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'src/core/hle/kernel/thread.cpp') diff --git a/src/core/hle/kernel/thread.cpp b/src/core/hle/kernel/thread.cpp index 7d03a2cf72..d44010824d 100644 --- a/src/core/hle/kernel/thread.cpp +++ b/src/core/hle/kernel/thread.cpp @@ -90,9 +90,6 @@ static bool CheckWait_AddressArbiter(const Thread* thread, VAddr wait_address) { } void Thread::Stop() { - // Release all the mutexes that this thread holds - ReleaseThreadMutexes(this); - // Cancel any outstanding wakeup events for this thread CoreTiming::UnscheduleEvent(ThreadWakeupEventType, callback_handle); wakeup_callback_handle_table.Close(callback_handle); @@ -108,6 +105,9 @@ void Thread::Stop() { WakeupAllWaitingThreads(); + // Release all the mutexes that this thread holds + ReleaseThreadMutexes(this); + // Clean up any dangling references in objects that this thread was waiting for for (auto& wait_object : wait_objects) { wait_object->RemoveWaitingThread(this); -- cgit v1.2.3
