From: Eric Anholt Date: Tue, 30 Apr 2013 18:15:05 +0000 (-0700) Subject: i965: Use brw_blorp_blit_miptrees() for CopyTexSubImage(). X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5b9609f59ac4e9079a6dea1212178070a45ab8e9;p=mesa.git i965: Use brw_blorp_blit_miptrees() for CopyTexSubImage(). Now that depth resolves are handled there, we don't need to make the temporary renderbuffer.
