From 34683150878e0af0859c94d0c1f0c4bf8395b042 Mon Sep 17 00:00:00 2001 From: Robert Ellison Date: Wed, 4 Mar 2009 16:48:51 -0700 Subject: i965: add software fallback for conformant 3D textures and GL_CLAMP The i965 hardware cannot do GL_CLAMP behavior on textures; an earlier commit forced a software fallback if strict conformance was required (i.e. the INTEL_STRICT_CONFORMANCE environment variable was set) and 2D textures were used, but it was somewhat flawed - it could trigger the software fallback even if 2D textures weren't enabled, as long as one texture unit was enabled. This fixes that, and adds software fallback for GL_CLAMP behavior with 1D and 3D textures. It also adds support for a particular setting of the INTEL_STRICT_CONFORMANCE environment variable, which forces software fallbacks to be taken *all* the time. This is helpful with debugging. The value is: export INTEL_STRICT_CONFORMANCE=2 --- src/gallium/drivers/i915simple/i915_state_sampler.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'src/gallium') diff --git a/src/gallium/drivers/i915simple/i915_state_sampler.c b/src/gallium/drivers/i915simple/i915_state_sampler.c index c09c10601b..3667ed1afa 100644 --- a/src/gallium/drivers/i915simple/i915_state_sampler.c +++ b/src/gallium/drivers/i915simple/i915_state_sampler.c @@ -116,7 +116,7 @@ static void update_sampler(struct i915_context *i915, ws == PIPE_TEX_WRAP_CLAMP_TO_BORDER || wt == PIPE_TEX_WRAP_CLAMP_TO_BORDER || wr == PIPE_TEX_WRAP_CLAMP_TO_BORDER)) { - if (i915->strict_conformance) { + if (i915->conformance_mode > 0) { assert(0); /* sampler->fallback = true; */ /* TODO */ -- cgit v1.2.3
