Android: Implement TLB optimization to prevent deadlocks and improve performance

This commit addresses critical TLB (Translation Lookaside Buffer) issues on Android by implementing several optimizations: - Add new BufferCacheAccelerator to manage memory range overlap detection - Implement TLB-aware memory barriers to prevent unnecessary invalidations - Add a TLB caching system to avoid redundant flushing operations - Create a counter to limit outstanding memory operations and prevent TLB thrashing - Implement TLB prefetching for better memory access patterns - Add targeted memory barriers for more precise synchronization These changes significantly reduce the likelihood of the "0.0 FPS deadlock" issue on Android devices by maintaining a more stable TLB state and preventing cache thrashing.

Zephyron	21594b73aa	Android: Implement TLB optimization to prevent deadlocks and improve performance This commit addresses critical TLB (Translation Lookaside Buffer) issues on Android by implementing several optimizations: - Add new BufferCacheAccelerator to manage memory range overlap detection - Implement TLB-aware memory barriers to prevent unnecessary invalidations - Add a TLB caching system to avoid redundant flushing operations - Create a counter to limit outstanding memory operations and prevent TLB thrashing - Implement TLB prefetching for better memory access patterns - Add targeted memory barriers for more precise synchronization These changes significantly reduce the likelihood of the "0.0 FPS deadlock" issue on Android devices by maintaining a more stable TLB state and preventing cache thrashing.

Zephyron	d869045b77	build: Move PGO configuration to earlier in CMakeLists.txt The Profile-Guided Optimization configuration was previously placed at the end of the CMakeLists.txt file, after all targets were already defined. This was causing the PGO flags to have no effect on the build process. This commit moves the PGO configuration to immediately after the initial compiler flags setup and before any targets are defined, ensuring that all targets will properly receive the PGO instrumentation or optimization flags when those options are enabled. This allows both CITRON_ENABLE_PGO_INSTRUMENT and CITRON_ENABLE_PGO_OPTIMIZE to function correctly for all build targets. Signed-off-by: Zephyron <zephyron@citron-emu.org>	2025-03-13 17:03:21 +10:00
Zephyron	f2931c7566	vulkan: Implement AMD driver workaround for logic operations - Added conditional check for AMD graphics drivers - Automatically disable logic operations when float vertex attributes are present to work around driver quirks - Maintain original logic op state to preserve emulator behavior - Prepare dynamic state management infrastructure for future OpenGL implementation changes OpenGL implementation will follow in subsequent commits.
