So I've picked up the "easy" patches that I have read somewhat often and also tested myself using the lima driver on some Rockchip socs (rk3036 + mali400 and rk3328 + mali450). I'll try to also look at the rest but no guarantees on timing as they look a lot more involved in real graphics-related stuff :-) Thanks Heiko _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
