From b9789948e0b5c5fad7952ea5b731c675d50a4f58 Mon Sep 17 00:00:00 2001 From: Roland Scheidegger Date: Sat, 15 Aug 2009 03:44:02 +0200 Subject: [PATCH] i965: disable bounds checking on arrays with stride 0 if stride is 0 we cannot use count as max index for bounds checking, since the hardware will simply return 0 as data for indices failing bounds check. If stride is 0 any index should be valid hence simply disable bounds checking in this case. This fixes bugs introduced with e643bc5fc7afb563028f5a089ca5e38172af41a8. --- src/mesa/drivers/dri/i965/brw_draw_upload.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/mesa/drivers/dri/i965/brw_draw_upload.c b/src/mesa/drivers/dri/i965/brw_draw_upload.c index ab6b62812f1..d49fb0fd951 100644 --- a/src/mesa/drivers/dri/i965/brw_draw_upload.c +++ b/src/mesa/drivers/dri/i965/brw_draw_upload.c @@ -547,7 +547,7 @@ static void brw_emit_vertices(struct brw_context *brw) input->offset + input->element_size); } } else - OUT_BATCH(input->count); + OUT_BATCH(input->stride ? input->count : 0); OUT_BATCH(0); /* Instance data step rate */ } ADVANCE_BATCH(); -- 2.30.2
