From: Stéphane Marchesin Date: Sat, 25 Jun 2011 00:18:12 +0000 (-0700) Subject: i915g: add fake occlusion queries. X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=7b44830ef40b6d4644c3f55189ed2457e6822428;p=mesa.git i915g: add fake occlusion queries. Those always return 0, but at least we don't crash when exposing GL 2.0. --- diff --git a/src/gallium/drivers/i915/Makefile b/src/gallium/drivers/i915/Makefile index b3f387f9335..778124728bb 100644 --- a/src/gallium/drivers/i915/Makefile +++ b/src/gallium/drivers/i915/Makefile @@ -21,6 +21,7 @@ C_SOURCES = \ i915_screen.c \ i915_prim_emit.c \ i915_prim_vbuf.c \ + i915_query.c \ i915_resource.c \ i915_resource_texture.c \ i915_resource_buffer.c \ diff --git a/src/gallium/drivers/i915/SConscript b/src/gallium/drivers/i915/SConscript index 8f5deed64a9..98370601b7f 100644 --- a/src/gallium/drivers/i915/SConscript +++ b/src/gallium/drivers/i915/SConscript @@ -16,6 +16,7 @@ i915 = env.ConvenienceLibrary( 'i915_fpc_translate.c', 'i915_prim_emit.c', 'i915_prim_vbuf.c', + 'i915_query.c', 'i915_screen.c', 'i915_state.c', 'i915_state_derived.c', diff --git a/src/gallium/drivers/i915/i915_context.c b/src/gallium/drivers/i915/i915_context.c index ab4ea9a412e..6d2e10470cf 100644 --- a/src/gallium/drivers/i915/i915_context.c +++ b/src/gallium/drivers/i915/i915_context.c @@ -29,6 +29,7 @@ #include "i915_state.h" #include "i915_screen.h" #include "i915_surface.h" +#include "i915_query.h" #include "i915_batch.h" #include "i915_resource.h" @@ -172,6 +173,7 @@ i915_create_context(struct pipe_screen *screen, void *priv) i915_init_state_functions(i915);
