From: Derek Foreman <der...@osg.samsung.com> The Raspberry Pi boards can use one of two graphics stacks: The "userland" user-space driver or the VC4 drm/kms kernel driver. This patch documents how the user user can choose if the VC4 driver has to be used instead and set the right preferred providers for that case.
Signed-off-by: Derek Foreman <der...@osg.samsung.com> [javier: Extend commit msg and made conditional instead removing userland] Signed-off-by: Javier Martinez Canillas <jav...@osg.samsung.com> --- Changes in v2: - Don't add a feature and allow users to change the default provider manually aided by a comment.
