From 6d28bf917fb1d741d90fd3f05c22769376021fca Mon Sep 17 00:00:00 2001 From: Chia-I Wu Date: Fri, 16 Jul 2010 04:35:58 +0800 Subject: gallium: Implement draw_vbo and set_index_buffer for all drivers. Some drivers define a generic function that is called by all drawing functions. To implement draw_vbo for such drivers, either draw_vbo calls the generic function or the prototype of the generic function is changed to match draw_vbo. Other drivers have no such generic function. draw_vbo is implemented by calling either draw_arrays and draw_elements. For most drivers, set_index_buffer does not mark the state dirty for tracking. Instead, the index buffer state is emitted whenever draw_vbo is called, just like the case with draw_elements. It surely can be improved. --- src/gallium/drivers/svga/svga_pipe_vertex.c | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) (limited to 'src/gallium/drivers/svga/svga_pipe_vertex.c') diff --git a/src/gallium/drivers/svga/svga_pipe_vertex.c b/src/gallium/drivers/svga/svga_pipe_vertex.c index 23808ad08e..86c79459f3 100644 --- a/src/gallium/drivers/svga/svga_pipe_vertex.c +++ b/src/gallium/drivers/svga/svga_pipe_vertex.c @@ -66,6 +66,24 @@ static void svga_set_vertex_buffers(struct pipe_context *pipe, } +static void svga_set_index_buffer(struct pipe_context *pipe, + const struct pipe_index_buffer *ib) +{ + struct svga_context *svga = svga_context(pipe); + + if (ib) { + pipe_resource_reference(&svga->curr.ib.buffer, ib->buffer); + memcpy(&svga->curr.ib, ib, sizeof(svga->curr.ib)); + } + else { + pipe_resource_reference(&svga->curr.ib.buffer, NULL); + memset(&svga->curr.ib, 0, sizeof(svga->curr.ib)); + } + + /* TODO make this more like a state */ +} + + static void * svga_create_vertex_elements_state(struct pipe_context *pipe, unsigned count, @@ -109,6 +127,7 @@ void svga_cleanup_vertex_state( struct svga_context *svga ) void svga_init_vertex_functions( struct svga_context *svga ) { svga->pipe.set_vertex_buffers = svga_set_vertex_buffers; + svga->pipe.set_index_buffer = svga_set_index_buffer; svga->pipe.create_vertex_elements_state = svga_create_vertex_elements_state; svga->pipe.bind_vertex_elements_state = svga_bind_vertex_elements_state; svga->pipe.delete_vertex_elements_state = svga_delete_vertex_elements_state; -- cgit v1.2.3
