From: Marek Olšák Date: Fri, 6 Jul 2012 01:18:06 +0000 (+0200) Subject: r600g: do fine-grained vertex buffer updates X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=585baac652ffa172fb3fbbdd4c7559d03b7c27ef;p=mesa.git r600g: do fine-grained vertex buffer updates If only some buffers are changed, the other ones don't have to re-emitted. This uses bitmasks of enabled and dirty buffers just like emit_constant_buffers does. --- diff --git a/src/gallium/drivers/r600/evergreen_compute.c b/src/gallium/drivers/r600/evergreen_compute.c index 947a3283b0f..caaa752b77b 100644 --- a/src/gallium/drivers/r600/evergreen_compute.c +++ b/src/gallium/drivers/r600/evergreen_compute.c @@ -89,14 +89,15 @@ static void evergreen_cs_set_vertex_buffer( unsigned offset, struct pipe_resource * buffer) { - struct pipe_vertex_buffer *vb = &rctx->cs_vertex_buffer[vb_index];
