Hello,
I'm trying to get Android 12 up and running on my Galaxy Note 10.1 which is based on Exynos 4412 with a Mali GPU. For Android 11, I had no issues with graphics but after upgrading and building Android 12, I'm getting a vblank wait timeout shortly after starting the device setup, which in turn leads to my display turning black and SurfaceFlinger hanging. This can be reliably reproduced after every reboot, so much so that it's basically always on the exact same step of the setup.
I'm using the following setup:
* 5.10.101 Android Common Kernel with some patches to get the Note 10.1 up and running * Exynos FIMD + Lima GPU driver * android-12.1.0_r5 branch * drm-hwcomposer main branch * mesa main branch * minigbm from the GloDroid project
I tried several older versions of hwc, mesa and minigbm with no success, same problem on all of them. What I found is that, if I disable overlay planes and only the primary plane is used, it works without any issues. Adding the second plane is fine as well, but the third one triggers the problem. For some reason, this didn't happen on Android 11 though and nothing changed on the kernel side, I was using the same kernel for it.
Unfortunately, there is not a lot going on in the logging. In logcat I can see the following messages:
E hwc-drm-atomic-state-manager:sync_wait(fd=33) returned: -1 (errno: 62) E hwc-drm-atomic-state-manager: Failed to commit pset ret=-16 E hwc-drm-atomic-state-manager: Composite failed for pipeline VGA-1 E Fence: waitForever: Throttling EGL Production: fence 431 didn't signal in 3000 ms W OpenGLRenderer: dequeueBuffer failed,error = -110;
Here is the dmesg output of it:
