| | | | | | | | | | | In Vulkan, we'll compile the TCS and TES at the same time, so I can just pass the TCS output VUE map to brw_compile_tes as the TES input VUE map.

* i965/compiler: Use the new nir_opt_copy_prop_vars passJason Ekstrand2017-01-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We run this after nir_lower_vars_to_ssa so that as many load/store_var intrinsics as possible before copy_prop_vars executes. This is because the pass isn't particularly efficient (it does a lot of linear walks of a linked list) so we'd like as much of the work as possible to be done before copy_prop_vars runs.

On older hardware, the impact isn't as large because they don't advertise GL 4.5. Of the hurt programs, all but one are hurt by a single instruction and the one is hurt by 3 instructions. All of the helped programs, on the other hand, are helped by at least 3 instructions and one kerbal space program shader is helped by 44.59%. The real star of the show, however, is the Gl43CSDof synmark2 benchmark which has two shaders which are cut by 28% and 40% and the over-all runtime performance of the benchmark on my Sky Lake laptop is improved by around 25-30% (it's a bit hard to be exact due to thermal throttling).

* i965: Rework gl_TessLevel*[] handling to use NIR compact arrays.Kenneth Graunke2017-01-0610-364/+92
| | | | | | | | | | | | | | | | | | | | | | | | Treating everything as scalar arrays allows us to drop a bunch of special case input/output munging all throughout the backend. Instead, we just need to remap the TessLevel components to the appropriate patch URB header locations in remap_patch_urb_offsets(). We also switch to treating the TES input versions of these as ordinary shader inputs rather than system values, as remap_patch_urb_offsets() just makes everything work out without special handling. This regresses one Piglit test: arb_tessellation_shader-large-uniforms/GL_TESS_CONTROL_SHADER-array-at-limit The compiler starts promoting the constant arrays assigned to gl_TessLevel* to uniform arrays. Since the shader also has a uniform array that uses the maximum number of uniform components, this puts it over the uniform component limit enforced by the linker. This is arguably a bug in the constant array promotion code (it should avoid pushing us over limits), but is unlikely to penalize any real application.

However, when we move to treating them as inputs, this would cause a bug: with no TCS present, it would propagate TES reads of VARYING_SLOT_TESS_LEVEL into the VS output VUE map slots.

The GL 4.5 spec describes the algorithm of glGenerateMipmap as: The contents of the derived images are computed by repeated, filtered reduction of the level base image. [...] No particular filter algorithm is required, though a box filter is recommended as the default filter. Consider a texture for which all pixels are identical at level 0. From the spec's description above, one may reasonably assume that the "filtered reduction" of level 0 produces a new miplevel for which again all pixels are identical. For any 2x2 subspan of identical pixels, it is difficult to see how the "filtered reduction" of that subspan can produce a pixel that differs from the source pixels. Dithering during _mesa_meta_GenerateMipmap() violated that reasonable assumption.
