Graphics is an essential part of Halium. Halium uses libhybris to make Android’s bionic based hardware adaptations layer usable with glibc systems.
Here is some tests to test the graphics stack
Add tests using more heavy graphics applications using Wayland (mir)
If these tests fail but some others succeed (lights, vibrator, Wi-Fi), you may need software which is built for Code Aurora Forum’s Android for MSM (generally nicknamed “CAF” for short) rather than AOSP.
If this is the case, you’ll errors similar to the following in Logcat:
W Adreno-GSL: <gsl_ldd_control:475>: ioctl fd 8 code 0xc0140933 (IOCTL_KGSL_TIMESTAMP_EVENT) failed: errno 22 Invalid argument W Adreno-GSL: <ioctl_kgsl_syncobj_create:2984>: (9, 1, 62845) fail 22 Invalid argument W Adreno-EGLSUB: <SwapBuffers:1339>: gsl_device_3d_add_fence_event failed W Adreno-EGL: <qeglDrvAPI_eglSwapBuffers:3890>: EGL_BAD_SURFACE
On the reference rootfs, you can get this software from the Halium repository by running the following commands:
. /etc/environment echo "deb http://repo.halium.org/caf xenial main" >> /etc/apt/sources.list.d/halium-caf.list apt -get update apt-get dist-upgrade
Non-reference distributions will need to provide software which is compatible with CAF Android trees.
