Subject: iris: Support storage images that have matching typed formats for reads
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7cdde962c5f65165e28cae92da57d2d6e4d7a740;p=mesa.git

iris: Support storage images that have matching typed formats for reads

Even if we don't directly support typed reads on a format, we can often
translate them to a reasonable matching format.  Advertise those too.
