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/i915/i915_state.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) (limited to 'src/gallium/drivers/i915/i915_state.c') diff --git a/src/gallium/drivers/i915/i915_state.c b/src/gallium/drivers/i915/i915_state.c index e767aa9f8f..385c3b2d2d 100644 --- a/src/gallium/drivers/i915/i915_state.c +++ b/src/gallium/drivers/i915/i915_state.c @@ -812,6 +812,19 @@ i915_delete_vertex_elements_state(struct pipe_context *pipe, void *velems) FREE( velems ); } +static void i915_set_index_buffer(struct pipe_context *pipe, + const struct pipe_index_buffer *ib) +{ + struct i915_context *i915 = i915_context(pipe); + + if (ib) + memcpy(&i915->index_buffer, ib, sizeof(i915->index_buffer)); + else + memset(&i915->index_buffer, 0, sizeof(i915->index_buffer)); + + /* TODO make this more like a state */ +} + static void i915_set_sample_mask(struct pipe_context *pipe, unsigned sample_mask) @@ -860,4 +873,5 @@ i915_init_state_functions( struct i915_context *i915 ) i915->base.sampler_view_destroy = i915_sampler_view_destroy; i915->base.set_viewport_state = i915_set_viewport_state; i915->base.set_vertex_buffers = i915_set_vertex_buffers; + i915->base.set_index_buffer = i915_set_index_buffer; } -- cgit v1.2.3
