bunnei 46a620f9d7 hle: kernel: KThread: Decrease DummyThread priority to ensure it is never scheduled. 2022-01-20 17:08:00 -08:00
bunnei 11a380c3da hle: kernel: KScheduler: Ensure dummy threads are never scheduled. 
- These are only used by host threads for locking.

hle: remove no-op code 
Found by static analysis with PVS-Studio. Nobody seems to really know what was it doing there.

bunnei 3a89723d97 core: hle: kernel: Implement thread pinning. 
- 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.

Markus Wick 3d2e80daed core/arm_interface: Call SVC after end of dynarmic block. 
So we can modify all of dynarmic states within SVC without ExceptionalExit.

Especially as the ExceptionalExit hack is dropped on upstream dynarmic.

Lioncash 9a07ed53eb core: Make variable shadowing a compile-time error 
Now that we have most of core free of shadowing, we can enable the
warning as an error to catch anything that may be remaining and also
eliminate this class of logic bug entirely.

Lioncash 2f62bae9e3 kernel: Eliminate variable shadowing 
Now that the large kernel refactor is merged, we can eliminate the
remaining variable shadowing cases.

Revert "core: Switch to unique_ptr for usage of Common::Fiber." 2021-03-05 17:08:17 -08:00
bunnei 51fb0a6f96 core: Switch to unique_ptr for usage of Common::Fiber. 
- With using unique_ptr instead of shared_ptr, we have more explicit ownership of the context.
- Fixes a memory leak due to circular reference of the shared pointer.
