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
It's Android kernel, so not upstream. It is perfectly fine to use downstream kernels, but with the issues you also go to downstream folks. I have no clue what Android did to Exynos.
Best regards, Krzysztof
