Raspberry Pi KMS-Only, No-3D Driver Under Review

Just hours after writing about the Raspberry Pi firmware driver being under review for possible inclusion into Linux 4.3, Eric Anholt has posted some stripped down versions of his VC4 DRM driver for review.

This Raspberry Pi DRM/KMS driver makes use of the RPi firmware driver and why hours ago it looked like the new driver was on approach, and now it's panned out with the latest mailing list activity. However, for easing review, Eric posted just the basic VC4 DRM driver support that brings up frame-buffer console support over KMS and utilizes the xf86-video-modesetting driver on X.Org.

Changing video modes is unsupported right now as well as there being no 3D support with the patches, even though over in user-space Eric has been developing the VC4 Gallium3D driver and working to get a fully open 3D driver stack for these popular low-cost ARM development boards. Eric just didn't post the 3D support patches as part of this initial review series to make it easier for fellow open-source DRI developers to review the work.
