[RPi4] Switch to vc4 for display/sound (was rooted through efifb)
Last modified: 2022-01-21 14:18:15 UTC
With v5.10 vc4, the driver enabling RPi's display controller, now supports RPi4. Let's switch the board's kernel configuration and firmware config to use this instead of efifb, which is extremely limited (no sound, no resolution changes).
Among other things, some clocks have to be set-up as builtin, a fix is needed in u-boot so as to cater to DT changes involved in enabling vc4 and some overlays have to be selected in config.txt
I decided that, instead of setting clk-bcm2711-dvp as builtin which was needed as it didn't properly support being a module, to backport the fix, aimed at v5.11.
Petr (or someone else), what is the status of this? Since Nicolas not being at SUSE anymore...
This is fixed, according to the changes file , from 8th of March 2021:
- Enable VC4 by default on RPi4 (jsc#SLE-12151)
