This enables DRM (Direct Rendering Manager) support in the kernel for the RX51. This opens up the possibility of using the Weston DRM backend, which in turn allows for DPMS (I hope) and other cool tricks. n900:~# glxinfo|head name of display: :0 display: :0 screen: 0 direct rendering: Yes server glx vendor string: SGI server glx version string: 1.4 n900:~# glxgears 94 frames in 5.0 seconds = 18.772 FPS

# APKBUILD based on linux-vanilla aport. Changes:
|
|
# - disabled module installation
|
|
# - add !check !tracedeps
|
|
# - package: just install zimage and kernel.release, because the kernel config
|
|
# does not generate modules or dtb files
|
|
# - do not create -dev subpackage (makes no sense without module support)
|
|
#
|
|
# Kernel config based on: arch/arm/configs/lineageos_mako_defconfig
|
|
# Changes:
|
|
# - enable devtmpfs (needed for udev -> touch support in weston)
