bunnei 5ffec69dc7 hle: kernel: KThread: Ensure dummy threads never call EndWait. 
- These are only used by host threads for locking and will never have a wait_queue.

bunnei 11a380c3da hle: kernel: KScheduler: Ensure dummy threads are never scheduled. 
- These are only used by host threads for locking.

bunnei f6cbb14dce hle: kernel: KThread: Rename thread_type_for_debugging -> thread_type. 
- This will be used to ensure that we do not schedule dummy threads.

hle: remove no-op code 
Found by static analysis with PVS-Studio. Nobody seems to really know what was it doing there.
 2022-01-17 13:51:12 +03:00
bunnei b54cbc985e hle: kernel: k_memory_manager: Clear pages on allocation & free. 
- Heap pages should be zero'd.
- Also explicitly passed along heap allocation option.
 2022-01-14 21:16:33 -08:00
bunnei f499c8177e core: hle: kernel: KThread: Integrate with KWorkerTask and implement 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.

bunnei 03884b7ea6 core: hle: kernel: KThread: Replace Suspend with UpdateState & various updates.

bunnei bf32fcc817 core: hle: kernel: Add KWorkerTask and KWorkerTaskManager. 
- These primitives are used to dispatch asynchronous kernel tasks from KThread and KProcess.

bunnei cc112f971e hle: kernel: Fix service_threads access to be thread safe V2. 
- 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.

 2022-01-14 00:46:16 -05:00
bunnei 2147240e47 hle: kernel: Fix service_threads access to be thread safe. 
- 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.

bunnei c73841500a core: hle: Remove global HLE lock. 
- This was added early on as a hack to protect against some concurrency issues.
- It's not clear that this serves any purpose anymore, and if it does, individual components should be fixed rather than using a global recursive mutex.

Wunkolo 4569f39c7c common: Replace common_sizes into user-literals 
Removes common_sizes.h in favor of having `_KiB`, `_MiB`, `_GiB`, etc

To keep the global namespace clean, users will have to use:

```
using namespace Common::Literals;
```

to access these literals.
