feat(aurora): port Mali sanitizer + mid-end tier tuning#1
Conversation
Aurora integration into WinNative fork. Ports the working parts of Aurora
(per deep audit) and adds device-tier-aware performance tuning for mid-end
devices (the project's primary target audience).
## What's ported from Aurora (with audit fixes)
Mali Vulkan Sanitizer (5 rules, B4+B6 fixes applied on top of latest Aurora):
- 4 blacklisted extensions: VK_EXT_descriptor_indexing,
VK_EXT_fragment_density_map, VK_KHR_shader_subgroup,
VK_EXT_graphics_pipeline_library
- 1 descriptor-set split at >4 sets (Mali driver crashes on >4)
- B4 fix: dynamic offsets now sliced correctly per chunk. Previously
chunks 2+ received 0 dynamic offsets, causing silent wrong rendering
for any draw using sets 4+ with dynamic UBO bindings. New hooks:
vkCreateDescriptorSetLayout (caches per-layout dynamic count),
vkAllocateDescriptorSets/vkFreeDescriptorSets (caches per-set count),
used in vkCmdBindDescriptorSets to slice pDynamicOffsets per chunk.
- B6 fix: device resolved per-command-buffer instead of hard-coding
g_device_dispatch[0]. New hooks: vkAllocateCommandBuffers,
vkFreeCommandBuffers (maintain VkCommandBuffer -> VkDevice map).
- Inherits Aurora's audit fixes: B1 (layer name match), B2 (env var
ordering), B3 (glibc compile), B5 (thread-safe dispatch tables),
B9 (Immortalis detection).
## What's dropped (dead code per audit)
- Phase 1 texture engine (no PC game ships .ktx2)
- Phase 2 mesh engine (no PC game ships .obj)
- Phase 3 Markov prefetcher (no LD_PRELOAD shim exists)
- Phase 4 cloud shader sync (no backend)
## What's new for mid-end tuning (the project goal)
DeviceTier.kt:
- Classifies device as HIGH/MID/LOW based on SoC + RAM + GPU.
- HIGH: Snapdragon 8 Gen 2+, Dimensity 9200+, Immortalis, 12GB+ RAM
- MID: Snapdragon 7xx, Dimensity 7/8, Mali G610/G77/G78, 6-8GB RAM
- LOW: Snapdragon 4xx/6xx, Mali G52/G72, 4GB RAM
TierPresets.kt:
- Per-tier env var defaults, applied via putIfAbsent so user overrides win.
- MID: BOX64_DYNAREC_STRONGMEM=2, BIGBLOCK=1, CALLRET=1, FASTNAN/ROUND=1,
SAFEFLAGS=1; DXVK maxFeatureLevel=11_0, relaxedBarriers=True,
useDescriptorIndexing=False, shaderUseSubgroupOps=False;
MESA_SHADER_CACHE_MAX_SIZE=512MB; WINEESYNC=1.
- LOW: All MID settings plus STRONGMEM=3, maxFeatureLevel=10_0,
usePipelineLibrary=False, shader cache 256MB.
- HIGH: dxvk.useDescriptorIndexing=True, d3d11.maxFeatureLevel=12_0.
NTSyncHelper.kt:
- Auto-detects /dev/ntsync (Linux 6.14+ kernel primitive).
- Enables WINENTSYNC=1 + PROTON_USE_NTSYNC=1 when available.
- Overrides esync fallback for ~10-20% sync overhead reduction.
MemoryBudgetHelper.kt:
- <6GB RAM: caps DXVK pipeline cache to 512MB.
- <4GB RAM: disables PulseAudio (AURORA_DISABLE_PULSEAUDIO=1 marker),
caps cache to 256MB, raises BOX64_DYNAREC_STRONGMEM=3.
## Integration points
GuestProgramLauncherComponent.java:
- Aurora helpers called AFTER envVars.putAll(this.envVars) so user/container
env vars merge first; tier presets only fill gaps via putIfAbsent.
- Order: TierPresets -> NTSyncHelper -> MemoryBudget -> MaliSanitizer.
- Wrapped in try/catch: Aurora helpers never block game launch.
ImageFsInstaller.java:
- Deploys libaurora_mali_sanitizer.so from APK to imagefs/usr/lib/.
- Writes Vulkan layer manifest JSON with name 'Aurora_Mali_Sanitizer'
(matches AuroraSanitizerHelper.LAYER_NAME).
- Falls back to DXVK_CONFIG mode if .so missing.
EnvVars.java:
- Added putIfAbsent() for tier presets (preserves user overrides).
CMakeLists.txt:
- Builds libaurora_mali_sanitizer.so as shared lib, linked to vulkan+log+dl.
## Not verified in this environment
- No Android SDK/NDK available here; static verification only (brace
balance, hook dispatch wiring, API surface checks against WinNative
source). Real compile happens in GitHub Actions CI on push.
- No real Mali device available here; the B4 dynamic-offset fix is
verified by static trace (one happy path + two fallback paths) but
not by runtime testing on a game that uses >4 dynamic UBO sets.
- DeviceTier classification is heuristic; real-world tier assignment
needs validation on actual mid-end hardware (Snapdragon 7 Gen 1/2,
Mali G610, etc.).
## Honest scope notes
- UI tab for Aurora status is NOT included. Per Module 4 (Definition of
Done), a UI display would need a real consumer; for now the tier is
logged at launch (logcat tag: AuroraTierPresets, AuroraDeviceTier)
which is a real producer+consumer (logs -> user reads logcat).
- Aurora SanitizerHelper detects Mali via GPUInformation.getRenderer(),
same as WinNative's existing Mali checks. Immortalis-prefix strings
are now also detected (B9 fix).
…ot (context) CI caught: DeviceTier.kt:48 called getRenderer(context) but the WinNative signature is getRenderer(String driverName, Context context). Pass null for driverName to use the active driver, matching how GuestProgramLauncherComponent calls it at line 869.

When full sanitizer mode is enabled, the Vulkan loader has to dlsym the exact function names from the manifest, but these entrypoints are in a .cpp file without extern "C" and the CMake target also uses -fvisibility=hidden. On Mali devices where the .so and JSON are deployed, the loader will not find exported symbols named vkNegotiateLoaderLayerInterfaceVersion/vkGetInstanceProcAddr, so the requested VK_INSTANCE_LAYERS layer either fails to load or prevents Vulkan instance creation instead of applying the sanitizer.

This code runs for every guest launch, but the app supports minSdk 26 and Build.SOC_MODEL/SOC_MANUFACTURER only exist on API 31+. On Android 8–11, resolving these fields throws NoSuchFieldError (not caught by the launcher’s catch (Exception)), so launching a game can crash before the tier presets are applied; use an SDK check like the existing callers in the repo do before reading these fields.

In fallback mode this guard skips all Mali workarounds whenever DXVK_CONFIG already mentions dxvk.useDescriptorIndexing; that includes high-tier Mali/Immortalis devices, because TierPresets runs first and writes dxvk.useDescriptorIndexing = True. If the native layer is absent or deployment fails, fallback then preserves the crashing setting and also omits the pipeline-library/subgroup caps, so the Mali fallback does not actually protect those launches.

The layer stores vkEnumerateDeviceExtensionProperties but never returns a hook for it here, so DXVK and other apps still see the blacklisted Mali extensions during capability probing. vkCreateDevice later silently removes those names from a copied create-info, leaving the app’s feature decisions based on extensions it believes are enabled; this can keep the Mali crash paths active or produce invalid extension use after device creation.

CI caught: GuestProgramLauncherComponent.java called TierPresets.apply(), NTSyncHelper.applyIfSupported(), MemoryBudgetHelper.apply(), and AuroraSanitizerHelper.setupSanitizer() as static methods, but Kotlin 'object' declarations expose instance methods on INSTANCE by default. Adding @JvmStatic generates proper static facade methods callable from Java without changing the Kotlin call syntax.
