Thanks a bunch to Chris, Ken, and Daniel for all the good review comments!
1-7, and 12-15 have Reviewed-by tags. I've dropped 16 pending a
WC-aware linear-to-tiled function.
8, 9, and 10 are missing reviews. I think we're good to leave their
contents as is, with an addition to 10's commit message.
I've sent four patches to replace 11 as suggested by Ken, which I
think yields the exact same result.
Thanks!
Additional TODO items picked up from review comments:
Handle cache_coherent flag for dma_buf imports
Handle
GL_MAP_INVALIDATE_RANGE_BIT
GL_MAP_INVALIDATE_BUFFER_BIT
GL_MAP_FLUSH_EXPLICIT_BIT
Move bufmgr->lock into the bo.
Remove map_count
Test for WC mappings only once in the screen
Do clflushing in userspace
Make a WC-aware linear-to-tiled function and use it in
intel_texsubimage_tiled_memcpy()
