From 40e2a5c15d09e02a71711735564151c789f95032 Mon Sep 17 00:00:00 2001 From: Alex Deucher Date: Fri, 4 Jun 2010 18:41:42 -0400 Subject: [PATCH] drm/radeon/kms: fix CS alignment checking for tiling (v2) Covers depth, cb, and textures. Hopefully I got this right. v2: - fix bugs: https://bugs.freedesktop.org/show_bug.cgi?id=28327 https://bugs.freedesktop.org/show_bug.cgi?id=28381 - use ALIGNED(), IS_ALIGNED() macros Signed-off-by: Alex Deucher Signed-off-by: Dave Airlie --- drivers/gpu/drm/radeon/r600_cs.c | 175 ++++++++++++++++++++++++------- 1 file changed, 136 insertions(+), 39 deletions(-) diff --git a/drivers/gpu/drm/radeon/r600_cs.c b/drivers/gpu/drm/radeon/r600_cs.c index 5cab1b413b6c..39bac5c3bb2b 100644 --- a/drivers/gpu/drm/radeon/r600_cs.c +++ b/drivers/gpu/drm/radeon/r600_cs.c @@ -25,6 +25,7 @@ * Alex Deucher * Jerome Glisse */ +#include #include "drmP.h" #include "radeon.h" #include "r600d.h" @@ -166,7 +167,7 @@ static void r600_cs_track_init(struct r600_cs_track *track) static inline int r600_cs_track_validate_cb(struct radeon_cs_parser *p, int i) { struct r600_cs_track *track = p->track;
