Subject: clover: use pipe_image_view for images instead of set_compute_resources
X-Git-Tag: upstream/21.0.0~3526
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3aead7198bcbb5ed0b58b3c84119f1ce28793f70;p=platform%2Fupstream%2Fmesa.git

clover: use pipe_image_view for images instead of set_compute_resources

Long term we want to git rid of set_compute_resources, this is just one
piece. The other bit would be to use the proper const buffer interfaces,
but because that path is only hit with r600/radeonsi I won't touch it.
