i965/dri: Handle the linear fb modifier
At image creation create a path for dealing with the linear modifier. This works exactly like the old usage flags where __DRI_IMAGE_USE_LINEAR was specified. During development of this patch series, it was decided that a lack of modifier was an insufficient way to express the required modifiers. As a result, 0 was repurposed to mean a modifier for a LINEAR layout. NOTE: This patch was added for v3 of the patch series. v2: Rework the algorithm for modifier selection to go from a bitmask based selection to this priority value. v3: Make DRM_FORMAT_MOD_INVALID allowed at selection as a way of identifying no modifiers found (because 0 is LINEAR) (Jason) v4: Remove the logic to prune unknown modifiers (like those from other vendors) and simply handle is in select_best_modifier (Jason) Requested-by: Jason Ekstrand <[email protected]> Signed-off-by: Ben Widawsky <[email protected]> Reviewed-by: Jason Ekstrand <[email protected]>
