[Mesa-dev] [PATCH v3 0/4] Android kms_swrast support

This series implements kms_swrast support for the Android
platform. And since having to debug a null pointer dereference,
simplify that process for the next guy.

As it stands now, any kernel must have the following ioctls flagged with
DRM_RENDER_ALLOW[1], which isn't the case in the mainline kernel.


I've started a seperate discussion on the kernel ML[1] to seeks some more answers
about what the upstream linux community views as the best solution
