Subject: i965: Fix the last valid address setting for the index buffer.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=f3be27c0cf8a4c47230f31d9d66bde7340ffb204;p=mesa.git

i965: Fix the last valid address setting for the index buffer.

Again, last valid address, not first invalid address.  Fixes regression
in 255e5be265133280293bbfd8b2f9b74b2dec50bb that the kernel now catches
and caused piglit draw_elements_base_vertex to fail.
