hle: kernel: KPageTable: Migrate locks to KScopedLightLock.
2022-02-02general: Replace NonCopyable struct with equivalentsLioncash
2022-02-02general: Move deleted copy/move constructor/assignment operators to public ↵Lioncash
interface This allows for better compiler errors, where the compiler will state a copy or move couldn't occur due to the relevant function being deleted. Previously a compiler would warn about the relevant function not being accessible (which, while true, isn't as informative as it could be).
2022-02-01hle: kernel: KPageTable: Migrate locks to KScopedLightLock.bunnei
- More accurately reflects real kernel behavior by using guest locks.

that has migrated. - Previously, it was possible for a thread migration to occur from core A to core B. - Next, core B waits on a guest lock that must be released by a thread queued for core A. - Meanwhile, core A is still waiting on the core B's current thread lock - resulting in a deadlock. - Fix this by try-locking the thread lock. - Fixes softlocks in FF8 and Pokemon Legends Arceus.

This is already checked inside GetCoreBit()
2022-01-22hle: kernel: KThread: Improve Increment/Decrement RunningThreadCount.bunnei
- Previously implementation was incorrect, and would occasionally underflow.

2022-01-21hle: kernel: KThread: Ensure host (dummy) threads block on locking.bunnei
- But do not enter the priority queue, as otherwise they will be scheduled. - Allows dummy threads to use guest synchronization primitives.
2022-01-20hle: kernel: Remove redundant tracking of dummy threads.bunnei
- These are already tracked by kernel's registered_objects member.
2022-01-20hle: kernel: KThread: DummyThread can be waited, ensure wait_queue is not ↵bunnei
nullptr.
2022-01-20hle: kernel: KThread: Decrease DummyThread priority to ensure it is never ↵bunnei
scheduled.

thread exit.
2022-01-20hle: kernel: KServerSession: Remove hack for CompleteSyncRequest.bunnei
- This does not appear to be necessary anymore.
2022-01-20hle: kernel: KServerSession: Simplify CompleteSyncRequest EndWait.bunnei
- Considering is_thread_waiting is never set, so we can remove IsThreadWaiting. - KThread::EndWait will take the scheduler lock, so we can remove the redundant lock.
2022-01-20hle: kernel: KThread: Ensure dummy threads never call EndWait.bunnei
- These are only used by host threads for locking and will never have a wait_queue.
2022-01-20hle: kernel: KScheduler: Ensure dummy threads are never scheduled.bunnei
- These are only used by host threads for locking.
2022-01-20hle: kernel: KThread: Rename thread_type_for_debugging -> thread_type.bunnei
- This will be used to ensure that we do not schedule dummy threads.

Kernel Memory Updates (Part 3): Clear KMemoryManager pages & other fixes
2022-01-17Merge pull request #7712 from bunnei/fix-thread-exitbunnei
Accurately implement thread exit
2022-01-17hle: remove no-op codeValeri
Found by static analysis with PVS-Studio. Nobody seems to really know what was it doing there.
2022-01-14hle: kernel: k_memory_manager: Clear pages on allocation & free.bunnei
- Heap pages should be zero'd. - Also explicitly passed along heap allocation option.
2022-01-14core: hle: kernel: KThread: Integrate with KWorkerTask and implement ↵bunnei
DoWorkerTaskImpl. - This is used to terminate a thread asynchronously after it has been exited. - This fixes a crash that can occur in Pokemon Sword/Shield because a thread is incorrectly closed on svcExitThread, then, the thread is destroyed on svcCloseHandle while it is still scheduled. - Instead, we now wait for the thread to no longer be scheduled on all cores before destroying it from KWorkerTaskManager, which is accurate to HOS behavior.
2022-01-14core: hle: kernel: KProcess: Integrate with KWorkerTask and add ↵bunnei
unimplemented DoWorkerTaskImpl.
2022-01-14core: hle: kernel: KThread: Replace Suspend with UpdateState & various updates.bunnei
- This makes our implementations of these more closely match HOS.
2022-01-14core: hle: kernel: Instantiate a kernel instance of KWorkerTaskManager.bunnei
2022-01-14core: hle: kernel: Add KWorkerTask and KWorkerTaskManager.bunnei
- These primitives are used to dispatch asynchronous kernel tasks from KThread and KProcess.
2022-01-14hle: kernel: Fix service_threads access to be thread safe V2.bunnei
- PR #7699 attempted to fix CreateServiceThread and ReleaseServiceThread to be thread safe, but inadvertently introduced a possible dead-lock. - With this PR, we use a worker thread to manage the service thread list, allowing it only to be accessed by a single thread, and guaranteeing threads will not destroy themselves. - Fixes a rare crash in Pokemon Sword/Shield, I've now run this game for ~12 hours non-stop and am quite confident this is a good solution for this issue.

hle: kernel: Fix service_threads access to be thread safe.
2022-01-13hle: kernel: Fix service_threads access to be thread safe.bunnei
- CreateServiceThread and ReleaseServiceThread can be accessed by different threads, uses a lock to make this thread safe. - Fixes a rare crash in Pokemon Sword/Shield that can occur when a new service thread is being created while an old one is being destroyed.

2021-12-30core: hle: kernel: Implement thread pinning.bunnei
- We largely had the mechanics in place for thread pinning, this change hooks these up. - Validated with tests https://github.com/Atmosphere-NX/Atmosphere/blob/master/tests/TestSvc/source/test_thread_pinning.cpp.
2021-12-28core: hle: kernel: Updated implementation of svcSetHeapSize.bunnei
- Updates our svcSetHeapSize with latest HOS, furthermore allowing heap size to properly be extended/shrunk. - Validated with tests https://github.com/Atmosphere-NX/Atmosphere/blob/master/tests/TestSvc/source/test_set_heap_size.cpp.
