From a56ccb90c6a374c86158ac2323f844a4003560fa Mon Sep 17 00:00:00 2001 From: Brian Paul Date: Wed, 6 Aug 2008 19:15:10 -0600 Subject: [PATCH] gallium: fix clipping/stride bugs in pipe_get_tile_raw(), pipe_put_tile_raw() We need to compute the default dst_stride and src_stride _before_ clipping. After clipping, the width value may have changed. This fixes visible tile glitches in some demos like progs/glsl/texdemo.c --- src/gallium/auxiliary/util/p_tile.c | 12 ++++++------ 1 file changed, 6 insertions(+), 6 deletions(-) diff --git a/src/gallium/auxiliary/util/p_tile.c b/src/gallium/auxiliary/util/p_tile.c index 2b6db43bee6..d65e603785c 100644 --- a/src/gallium/auxiliary/util/p_tile.c +++ b/src/gallium/auxiliary/util/p_tile.c @@ -51,12 +51,12 @@ pipe_get_tile_raw(struct pipe_surface *ps, { const void *src; - if (pipe_clip_tile(x, y, &w, &h, ps)) - return; - if (dst_stride == 0) dst_stride = pf_get_nblocksx(&ps->block, w) * ps->block.size; + if (pipe_clip_tile(x, y, &w, &h, ps)) + return; + src = pipe_surface_map(ps, PIPE_BUFFER_USAGE_CPU_READ); assert(src); if(!src) @@ -79,12 +79,12 @@ pipe_put_tile_raw(struct pipe_surface *ps, { void *dst; - if (pipe_clip_tile(x, y, &w, &h, ps)) - return; - if (src_stride == 0) src_stride = pf_get_nblocksx(&ps->block, w) * ps->block.size; + if (pipe_clip_tile(x, y, &w, &h, ps)) + return; + dst = pipe_surface_map(ps, PIPE_BUFFER_USAGE_CPU_WRITE); assert(dst); if(!dst) -- 2.30.2
