From 174f4900b294f939c85cfa94f5d8401ce73e5522 Mon Sep 17 00:00:00 2001 From: Jason Ekstrand Date: Mon, 24 Oct 2016 14:27:32 -0700 Subject: [PATCH] i965/blit: Remove a bogus assertion This assertion, while valid for linear buffers, doesn't work properly for tiled memory. It used to work most of the time because the offset provided was always to the left-hand edge of the image. However, if you use a byte offset to get to the inside of the image, the height * stride calculation may actually end up being too large.
