From 78068a5fbfc21fb52b289a81142b4211628f845c Mon Sep 17 00:00:00 2001 From: Marek Olšák Date: Tue, 7 Dec 2010 06:24:06 +0100 Subject: r300g: cache packet dwords of 3D_LOAD_VBPNTR in a command buffer if possible It's not always possible to preprocess the content of 3D_LOAD_VBPNTR in a command buffer, because the offset to all vertex buffers (which the packet depends on) is derived from the "start" parameter of draw_arrays and the "indexBias" parameter of draw_elements, but we can at least lazily make a command buffer for the case when offset == 0, which should occur most of the time. --- src/gallium/drivers/r300/r300_emit.c | 73 +++++++++++++++++++++++++++++------- 1 file changed, 59 insertions(+), 14 deletions(-) (limited to 'src/gallium/drivers/r300/r300_emit.c') diff --git a/src/gallium/drivers/r300/r300_emit.c b/src/gallium/drivers/r300/r300_emit.c index 45814f7493..82391e11a9 100644 --- a/src/gallium/drivers/r300/r300_emit.c +++ b/src/gallium/drivers/r300/r300_emit.c @@ -29,6 +29,7 @@ #include "util/u_simple_list.h" #include "r300_context.h" +#include "r300_cb.h" #include "r300_cs.h" #include "r300_emit.h" #include "r300_fs.h" @@ -806,39 +807,83 @@ void r300_emit_textures_state(struct r300_context *r300, END_CS; } -void r300_emit_aos(struct r300_context* r300, int offset, boolean indexed) +static void r300_update_aos_cb(struct r300_context *r300, unsigned packet_size) { struct pipe_vertex_buffer *vb1, *vb2, *vbuf = r300->vertex_buffer; struct pipe_vertex_element *velem = r300->velems->velem; - struct r300_buffer *buf; - int i; unsigned *hw_format_size = r300->velems->hw_format_size; unsigned size1, size2, aos_count = r300->velems->count; - unsigned packet_size = (aos_count * 3 + 1) / 2; - CS_LOCALS(r300); - - BEGIN_CS(2 + packet_size + aos_count * 2); - OUT_CS_PKT3(R300_PACKET3_3D_LOAD_VBPNTR, packet_size); - OUT_CS(aos_count | (!indexed ?
