From: Marek Olšák Date: Fri, 30 Mar 2012 21:39:55 +0000 (+0200) Subject: r600g: kill off the fallback for crazy src_offset values X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=5c03d1fa0fbe130153a2e4c937f684c680ca20b2;p=mesa.git r600g: kill off the fallback for crazy src_offset values st/mesa doesn't allow src_offset to be greater than stride and the maximum stride r600 supports is 2047.
