* xlib: use _mesa_generate_mipmap() for mipmap generation, not metaBrian Paul2013-01-291-0/+3
| | | | | | | | | | | | | | | | | | The swrast fragment program interpreter has trouble computing the right texture LOD because it doesn't have easy access to input derivatives. This causes the GLSL-based meta generate mipmap code to fetch texels from the wrong mipmap level. One possible fix would be to set the GL_TEXTURE_MIN/MAX_LOD parameters to limit sampling from the right level. But let's just use the _mesa_generate_mipmap() fallback since it's a lot faster than using the fragment shader interpreter. Fixes http://bugs.freedesktop.org/show_bug.cgi?id=54240 Note: This is a candidate for the 9.0 branch. Reviewed-by: José Fonseca <[email protected]>
* st/mesa: set ctx->Const.MaxSamples = 0, not 1Brian Paul2013-01-291-0/+4
| | | | | | | | | | The gallium docs for pipe_screen::is_format_supported() says that samples==0 or samples==1 both mean that multisampling is not supported. Return GL_MAX_SAMPLES==0 instead of 1 for consistency with other drivers. Note: This is a candidate for the 9.0 branch. Reviewed-by: Marek Olšák <[email protected]>

* intel: Use a CPU map of the batch on LLC-sharing architectures.Eric Anholt2013-01-294-9/+24
| | | | | | | | | | | | | | | | Before, we were keeping a CPU-only buffer to accumulate the batchbuffer in, which was an improvement over mapping the batch through the GTT directly (since any readback or other failure to stream through write combining correctly would hurt). However, on LLC-sharing architectures we can do better by mapping the batch directly, which reduces the cache footprint of the application since we no longer have this extra copy of a batchbuffer around. Improves performance of GLBenchmark 2.1 offscreen on IVB by 3.5% +/- 0.4% (n=21). Improves Lightsmark performance by 1.1 +/- 0.1% (n=76). Improves cairo-gl performance by 1.9% +/- 1.4% (n=57). No statistically significant difference in GLB2.1 on SNB (n=37). Improves cairo-gl performance by 2.1% +/- 0.1% (n=278).

| | | | | | | | | | | | | | | | | | | | | Interfaces are structurally identical to structures from the compiler's point of view. They have some additional restrictions, and generally GPUs use different instructions to access them. Using a different base type should make this a bit easier. This commit also adds the glsl_type::interface_packing fields. For GLSL_TYPE_INTERFACE types, this will track the specified packing mode. It is analogous to gl_uniform_buffer::_Packing. v2: Add serveral missing GLSL_TYPE_INTERFACE cases in switch-statements. v3: Add information about glsl_type::interface_packing.

* i965: Use GL_RED for DEPTH_TEXTURE_MODE in ES 3.0 for unsized formats.Kenneth Graunke2013-01-254-7/+21
| | | | | | | | | | | | | | | | | | | | | Khronos has apparently decided that depth textures with sized formats (allowed with ARB_internalformat_query or ES 3.0) should be treated as GL_RED, while unsized formats (an existing feature) should be treated as GL_INTENSITY for compatibility with ES 2.0. Ian is proposing changes to ARB_internalformat_query which will make this actually legal and consistent. A similar problem exists with GL 4.2, but we're going to ignore that for the time being.
