Subject: i965: Fix the region's pitch condition to use blitter
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b3094d9927fe7aa5a84892262404aaad4d728724;p=mesa.git

i965: Fix the region's pitch condition to use blitter

intelEmitCopyBlit uses a signed 16-bit integer to represent
buffer pitch, so it can only handle buffer pitches < 32k.
