commit: https://git.buildroot.net/buildroot/commit/?id=c19e2f44cccf65f34c416ecda9a9ebd96608891f
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master
kmsro allow to support KMS displays with the renderonly layer used to
attach a GPU [1].
Quote from mesa3d meson.build: "kmsro driver requires one or more
renderonly drivers (vc4, etnaviv, freedreno)". But only vc4 support is
available by using the (deprecated) autotools build system [2].
This will also be used by mesa to support KMSRO with the upcomming
Panfrost and Lima Gallium drivers.
