From: Corbin Simpson Date: Mon, 16 Feb 2009 10:53:34 +0000 (-0800) Subject: r300-gallium: Add draw_arrays and friends. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=1b77138a1effe2e18a9ce9e16c43852ff855a7be;p=mesa.git r300-gallium: Add draw_arrays and friends. This is the last bit of Gallium-side plumbing for drawing things. From this point on, the only missing parts should be in r3xx-specific code areas... --- diff --git a/src/gallium/drivers/r300/r300_context.c b/src/gallium/drivers/r300/r300_context.c index 7b605ae87ac..37dc9e86d64 100644 --- a/src/gallium/drivers/r300/r300_context.c +++ b/src/gallium/drivers/r300/r300_context.c @@ -22,6 +22,76 @@ #include "r300_context.h" +static boolean r300_draw_range_elements(struct pipe_context* pipe, + struct pipe_buffer* indexBuffer, + unsigned indexSize, + unsigned minIndex, + unsigned maxIndex, + unsigned mode, + unsigned start, + unsigned count) +{ + struct r300_context* r300 = r300_context(pipe);
