aports: add kmscube for testing kernel modesetting
Created by: zhuowei
kmscube is a command line utility for testing KMS-capable GPU drivers, which may be useful for validating DRM rendering and OpenGL ES acceleration capabilities required by accelerated Weston/KWin on supported devices.
I don't have a KMS capable device to test, so I made sure this works by
- installing mesa-dri-intel in the chroot_native
- mounting my host /dev and /sys into chroot_native
- switching to a different VT on my (Intel Haswell integrated graphics) host
- running kmscube
which shows a spinning cube on screen.
