X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=2822c8a0780ed57f8174389184740251dc5b0eda;p=mesa.git i965: Make the CopyImage BLT path bail for stencil images. The BLT can't handle S8 because it's W-tiled (at least without additional funny business, and I'm not sure we care). Disallow it so it falls back to the CPU path, which works.
