[yocto] [meta-raspberrypi][PATCH 4/5] linux-raspberrypi: Add a 4.1 linux kernel with vc4 support
Javier Martinez Canillas
javier at osg.samsung.com
Thu Jul 30 01:34:10 PDT 2015
From: Derek Foreman <derekf at osg.samsung.com>
This adds Eric Anholt's WIP kernel with dri/kms/3d support for the GPU on
the rpi2. Adding a recipe that tracks this kernel, will make it easier to
test this setup.
This recipe should only used for testing purposes for now, so it will not
be set as the default.
The kernel will be choosen though if the "vc4-gfx" feature has been added
to the the DISTRO_FEATURES variable.

+===================
+The Raspberry Pi boards can use one of two graphics stacks: The userland
+user-space driver or the vc4 DRM/KMS kernel driver. By default userland
