From a82da7fa263c7fb6b902285994136890e6dc3278 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Sun, 11 Oct 2009 11:04:09 -0700 Subject: i965: Fix the bounds emitted in the vertex buffer packets. It's the address of the last valid byte, not the address of the first invalid byte. This should also fix problems with rendering with the new sanity checks in the kernel. --- src/mesa/drivers/dri/i965/brw_draw_upload.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/mesa') diff --git a/src/mesa/drivers/dri/i965/brw_draw_upload.c b/src/mesa/drivers/dri/i965/brw_draw_upload.c index 4aa17fa02d7..5c332467498 100644 --- a/src/mesa/drivers/dri/i965/brw_draw_upload.c +++ b/src/mesa/drivers/dri/i965/brw_draw_upload.c @@ -539,12 +539,12 @@ static void brw_emit_vertices(struct brw_context *brw) if (input->stride) { OUT_RELOC(input->bo, I915_GEM_DOMAIN_VERTEX, 0, - input->offset + input->stride * input->count); + input->offset + input->stride * input->count - 1); } else { assert(input->count == 1); OUT_RELOC(input->bo, I915_GEM_DOMAIN_VERTEX, 0, - input->offset + input->element_size); + input->offset + input->element_size - 1); } } else OUT_BATCH(input->stride ? input->count : 0); -- cgit v1.2.3 From f3be27c0cf8a4c47230f31d9d66bde7340ffb204 Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Sun, 11 Oct 2009 11:16:03 -0700 Subject: i965: Fix the last valid address setting for the index buffer.
