From 0ed5bf668db24fb56b5b359399099c89531e2a0a Mon Sep 17 00:00:00 2001 From: Fabian Bieler Date: Mon, 14 Feb 2011 22:44:42 +0100 Subject: [PATCH] r600g: Request DWORD aligned vertex buffers. The spec says that the offsets in the vertex-fetch instructions need to be byte-aligned and makes no specification with regard to the required alignment of the offset and stride in the vertex resource constant register. However, testing indicates that all three values need to be DWORD aligned. --- src/gallium/drivers/r600/r600_pipe.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/gallium/drivers/r600/r600_pipe.c b/src/gallium/drivers/r600/r600_pipe.c index 9d6c9bd5429..79b0d02252d 100644 --- a/src/gallium/drivers/r600/r600_pipe.c +++ b/src/gallium/drivers/r600/r600_pipe.c @@ -196,7 +196,7 @@ static struct pipe_context *r600_create_context(struct pipe_screen *screen, void PIPE_BIND_VERTEX_BUFFER | PIPE_BIND_INDEX_BUFFER | PIPE_BIND_CONSTANT_BUFFER, - U_VERTEX_FETCH_BYTE_ALIGNED); + U_VERTEX_FETCH_DWORD_ALIGNED); if (!rctx->vbuf_mgr) { r600_destroy_context(&rctx->context); return NULL; -- 2.30.2
