From 566390bedf4e5f24b5234e9dc08ecb1a6fd4d13b Mon Sep 17 00:00:00 2001 From: Corbin Simpson Date: Thu, 4 Mar 2010 12:46:20 -0800 Subject: r300g: Fix indexbuf upper limits. Wine tends to pessimistically use ~0 for its max index, but r300s only can go up to 2^24-1, causing the kernel checker to freak out. Civ4 is marginally improved now. Still crashes, but not as bad. --- src/gallium/drivers/r300/r300_render.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-) (limited to 'src/gallium/drivers') diff --git a/src/gallium/drivers/r300/r300_render.c b/src/gallium/drivers/r300/r300_render.c index 770a92be74f..6c891029a56 100644 --- a/src/gallium/drivers/r300/r300_render.c +++ b/src/gallium/drivers/r300/r300_render.c @@ -273,9 +273,14 @@ static void r300_emit_draw_elements(struct r300_context *r300, CS_LOCALS(r300); assert((start * indexSize) % 4 == 0); + assert(count < (1 << 24)); + + DBG(r300, DBG_DRAW, "r300: Indexbuf of %u indices, min %u max %u\n", + count, minIndex, maxIndex); + + maxIndex = MIN2(maxIndex, ((1 << 24) - 1)); if (alt_num_verts) { - assert(count < (1 << 24)); BEGIN_CS(16); OUT_CS_REG(R500_VAP_ALT_NUM_VERTICES, count); } else { -- cgit v1.2.3
