|\ | | | | | | | | * commit 'db1597a98958b78dc0d8eced19ae1406382b70d6': Fix shutdown sequence to avoid SIGSEGV when running am command
| * Fix shutdown sequence to avoid SIGSEGV when running am commandJohannes Carlsson2012-06-251-2/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the app_process is shutting down the main thread will close the binder fd while pool threads are executing an ioctl (in IPCThreadState::stopProcess called by AppRuntime::onStarted in app_main.c). The binder driver will then return all pending calls in ioctl without any error and with a command. One of the threads gets a BR_SPAWN_LOOPER which will create a new thread (the other thread gets a BR_NOOP). This new thread then calls vm->AttachCurrentThread. Usually this results in a log entry with "AndroidRuntime: NOTE: attach of thread 'Binder Thread #3' failed", but sometimes it also causes a SIGSEGV. This depends on the timing between the new thread an the main thread that calls DestroyJavaVM (in AndroidRuntime::start). If IPCThreadState.cpp is compiled with "#define LOG_NDEBUG 0" the pool thread will loop and hit the ALOG_ASSERT(mProcess->mDriverFD >= 0) in IPCThreadState::talkWithDriver. Crashes like this has been seen when running the am command and other commands that use the app_process. This fix makes sure that any command that is received when the driver fd is closed are ignored and IPCThreadState::talkWithDriver instead returns an error which will cause the pool thread to exit and detach itself from the vm. A check to avoid calling ioctl to a fd with -1 was also added in IPCThreadState::threadDestructor. Another solution might be to change the binder driver so that it returns an error when the fd is closed (or atleast not a BR_SPAWN_LOOPER command). It might also be possible to call exit(0) which is done when System.exit(0) is called from java. Change-Id: I3d1f0ff64896c44be2a5994b3a90f7a06d27f429
* | Pass fences from BufferQueue to SurfaceTextureClientJesse Hall2012-06-213-18/+28
| | | | | | | | | | | | | | | | | | | | ISurfaceTexture::dequeueBuffer now returns the buffer's fence for the client to wait on. For BufferQueue, this means passing it through Binder so it can be returned to the SurfaceTextureClient. Now SurfaceTextureClient is responsible for waiting on the fence in dequeueBuffer instead of BufferQueue: one step closer to the goal. Change-Id: I677ae758bcd23acee2d784b8cec11b32cccc196d
* | Transfer HWC release fences to BufferQueueJesse Hall2012-06-215-15/+59
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After a HWC set, each SurfaceFlinger Layer retrieves the release fence HWC returned and gives it to the layer's SurfaceTexture. The SurfaceTexture accumulates the fences into a merged fence until the next updateTexImage, then passes the merged fence to the BufferQueue in releaseBuffer. In a follow-on change, BufferQueue will return the fence along with the buffer slot in dequeueBuffer. For now, dequeueBuffer waits for the fence to signal before returning. The releaseFence default value for BufferQueue::releaseBuffer() is temporary to avoid transient build breaks with a multi-project checkin. It'll disappear in the next change.
