From: Qicheng Christopher Li Date: Thu, 6 May 2010 17:45:42 +0000 (-0600) Subject: llvmpipe: implement occlusion query X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=86afe8250edaa2e6129c937a62a695f616c48d70;p=mesa.git llvmpipe: implement occlusion query OpenGL occlusion queries work now. The Mesa demos, glean test and piglit tests all pass. A few enhancements are possible in the future. -Brian Signed-off-by: Brian Paul --- diff --git a/src/gallium/drivers/llvmpipe/lp_bld_depth.c b/src/gallium/drivers/llvmpipe/lp_bld_depth.c index 1b59a13c946..e05bbe5011a 100644 --- a/src/gallium/drivers/llvmpipe/lp_bld_depth.c +++ b/src/gallium/drivers/llvmpipe/lp_bld_depth.c @@ -72,6 +72,7 @@ #include "gallivm/lp_bld_const.h" #include "gallivm/lp_bld_logic.h" #include "gallivm/lp_bld_flow.h" +#include "gallivm/lp_bld_intr.h" #include "gallivm/lp_bld_debug.h" #include "gallivm/lp_bld_swizzle.h" @@ -445,6 +446,42 @@ get_s_shift_and_mask(const struct util_format_description *format_desc, } +/** + * Perform the occlusion test and increase the counter. + * Test the depth mask.
