From 83458e7c53cfc1f344280da6eb9a3b4e2dfdbc00 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Thu, 18 Jun 2015 13:49:22 -0700 Subject: i965/fs: Use exec_size instead of dst.width for computing component size There are a variety of places where we use dst.width / 8 to compute the size of a single logical channel. Instead, we should be using exec_size.
