* [nce] handles duplicate NCE interrupts (#4530)xbzk9 days1-2/+2
| | | | | | | | | | | | | | | | | | | - [x] I have read and followed the [Contribution Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/CONTRIBUTING.md#code-contributions). - [x] I have read and followed the [AI Policy](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/AI.md). - [x] I have read and followed the [Coding Guidelines](https://git.eden-emu.dev/eden-emu/eden/src/branch/master/docs/policies/Coding.md) to the best of my ability. ------------------- Another crash observed in Ender Magnolia: A deadlock caused between CPUCore_0/GPU/GPUFencingThread. CPUCore_0 waits for GPU work inside the NCE fault handler GPU waits for the syncpoint mutex GPUFencingThread holds that mutex while waiting for CPUCore_0 NCE interrupt lock The fix makes duplicate interrupts return before acquiring the lock, while the first request keeps its original behavior.

* [NCE] Fix cache invalidation and signal interrupt race condition (#3063)MrPurple6662025-12-041-6/+21
| | | | | | | | | | | | | | | | Inspired by PR #3047 This should theoretically fix 3 bugs in NCE: - **Bug 1**: `ClearInstructionCache()` now properly invalidates L1 instruction cache using IC IALLU instead of only using memory barriers - **Bug 2**: `InvalidateCacheRange()` implements proper range-based cache invalidation instead of always flushing entire L1 cache - **Bug 3**: `SignalInterrupt()` adds acquire fence to guarantee memory visibility of the `is_running` flag, preventing lost signals Reviewed-on: https://git.eden-emu.dev/eden-emu/eden/pulls/3063 Reviewed-by: CamilleLaVey <camillelavey99@gmail.com> Reviewed-by: Caio Oliveira <caiooliveirafarias0@gmail.com> Co-authored-by: MrPurple666 <antoniosacramento666usa@gmail.com> Co-committed-by: MrPurple666 <antoniosacramento666usa@gmail.com>

* [android] Legacy build flavor (#51)Bix2025-10-051-1/+1
| | | | | | | | | | | | | | This adds a "legacy" build flavor, similar to the genshinSpoof flavor. The legacy flavor uses a white icon bg, alongside building with `YUZU_LEGACY=ON`, which applies the previously-made SD865 patches iff that value is truthy.

| | | | | | | | | | | | | | | | | | revert [Texture_cache] Better memory handling for devices with lower memory allocations (#233) Means games like Minecraft Dungeons, Sea of Stars, Luigi Mansion 2, Astroneer, Alan Wake, etc are now playable. It also cleans up the recent abi.cpp and bindless texture commits a bit. Everything is in #ifdef ANDROID - The biggest change is CACHING_PAGEBITS = 12. Without that the way the buffercache grows and joins buffers can cause Android to run out of memory (as you end up with just one big buffer that needs to be copied every time it grows) Also patches up ffmpeg issues.
