The freeze-with-audio in Ratchet & Clank is the RSX thread dying in the allocator, and the heap growth log says why. The index buffer went 16M to 64M to 128M to 192M to 256M inside 290ms, on requests of 2K, 4K, 5K and 3K; the attrib buffer did the same and died growing to 192M. Kilobyte allocations cannot need a quarter gigabyte. The rings were never wrapping, they were only ever growing. frame_context_cleanup is what returns a frame's ring memory, and check_present_status is what calls it. I removed that call from flush_command_queue in 0.5 because the drain poked the oldest queued frame's fence and on Adreno vkGetFenceStatus blocks until signalled instead of answering -- 14.6ms a frame, second only to the FIFO decode loop. The reasoning was that the flip path retires frames anyway. It does, enough to keep presenting, but not often enough to keep the rings bounded, and nothing else reclaims them. Restoring it costs nothing now. poke() no longer asks with vkGetFenceStatus: it uses vkWaitForFences with a zero timeout, which is specified to return VK_TIMEOUT without waiting. The measurement that motivated the removal was of the old implementation, so the speedup stays and the reclaim comes back. Keeps the heap growth log that found this. The allocator reports only a size and a pool number, and pool 1 covers every data_heap, so three fixes were aimed at a target that could not be seen. One line naming the heap settled it.
ARMSX3
Uses the latest RPCS3 upstream code (the recent ARM64 improvements included).
Building
Only arm64-v8a is supported. You need the Android SDK with NDK r27 or newer, CMake 3.30 or newer, and a JDK 17. Android Studio ships all of these.
Clone with submodules, then fetch the two third party checkouts that are not submodules:
git clone --recursive https://github.com/ARMSX2/ARMSX3.git
cd ARMSX3
git clone https://github.com/SnowflakePowered/librashader 3rdparty/librashader
git clone https://github.com/bylaws/libadrenotools android/armsx3-ui/app/src/main/cpp/libadrenotools
Build the core. This is the long part and produces an unstripped library of around 1.3 GB:
export ANDROID_HOME=$HOME/Library/Android/sdk
cmake -B build-android -G Ninja \
-DCMAKE_TOOLCHAIN_FILE=$ANDROID_HOME/ndk/<version>/build/cmake/android.toolchain.cmake \
-DANDROID_ABI=arm64-v8a -DANDROID_PLATFORM=android-31 \
-DCMAKE_BUILD_TYPE=RelWithDebInfo
cmake --build build-android --target rpcsx-android -j8
Strip it and put it where the app expects it:
llvm-strip --strip-unneeded build-android/android/libarmsx3-core.so
cp build-android/android/libarmsx3-core.so \
android/armsx3-ui/app/src/main/jniLibs/arm64-v8a/
Then build the app:
cd android/armsx3-ui
export JAVA_HOME="/Applications/Android Studio.app/Contents/jbr/Contents/Home"
./gradlew :app:assembleRelease
The apk lands in app/build/outputs/apk/release/.
Note that the core library has to be rebuilt and copied again whenever anything under rpcs3/ or android/src/ changes. Gradle does not build it for you.
The Discord Social SDK is proprietary and is not redistributed here. Get it from Discord's developer portal and drop it in app/libs/ and app/src/main/cpp/discord_sdk/ if you want that feature. The build skips it otherwise.
Running it needs PS3 firmware, which is not included. License
