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/nvfx/nvfx_state.c | 15 +++++++++++++++ 1 file changed, 15 insertions(+) (limited to 'src/gallium/drivers/nvfx/nvfx_state.c') diff --git a/src/gallium/drivers/nvfx/nvfx_state.c b/src/gallium/drivers/nvfx/nvfx_state.c index 30322d46d93..cd58e439d71 100644 --- a/src/gallium/drivers/nvfx/nvfx_state.c +++ b/src/gallium/drivers/nvfx/nvfx_state.c @@ -555,6 +555,20 @@ nvfx_set_vertex_buffers(struct pipe_context *pipe, unsigned count, nvfx->draw_dirty |= NVFX_NEW_ARRAYS; } +static void +nvfx_set_index_buffer(struct pipe_context *pipe, + const struct pipe_index_buffer *ib) +{ + struct nvfx_context *nvfx = nvfx_context(pipe); + + if (ib) + memcpy(&nvfx->idxbuf, ib, sizeof(nvfx->idxbuf)); + else + memset(&nvfx->idxbuf, 0, sizeof(nvfx->idxbuf)); + + /* TODO make this more like a state */ +} + static void * nvfx_vtxelts_state_create(struct pipe_context *pipe, unsigned num_elements, @@ -635,4 +649,5 @@ nvfx_init_state_functions(struct nvfx_context *nvfx) nvfx->pipe.bind_vertex_elements_state = nvfx_vtxelts_state_bind; nvfx->pipe.set_vertex_buffers = nvfx_set_vertex_buffers; + nvfx->pipe.set_index_buffer = nvfx_set_index_buffer; } -- cgit v1.2.3
