X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=b49982de6a52fdb7d0360d608badb103d15c04f1;p=mesa.git i965: Fix intel_bufferobj_buffer range for blit drawpixels. If the stride wasn't width*cpp, we wouldn't track how much of the src is busy, and allow a subdata into the end to proceed unsynchronized.
