Subject: r600g: prevent hardware blitting based on resource usage
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=a0a22fead5e08b9ebfd2b64e6262e1e803a8e927;p=mesa.git

r600g: prevent hardware blitting based on resource usage

It doesn't make much sense for STAGING and STREAM resources to be
hardware blitted into VRAM.
