* glsl/gs: Fix transform feedback of gl_ClipDistance.Paul Berry2013-10-243-1/+9
| | | | | | | | | | | | | | | | | | | | | | Since gl_ClipDistance is lowered from an array of floats to an array of vec4's during compilation, transform feedback has special logic to keep track of the pre-lowered array size so that attempting to perform transform feedback on gl_ClipDistance produces a result with the correct size. Previously, this special logic always consulted the vertex shader's size for gl_ClipDistance. This patch fixes it so that it uses the geometry shader's size for gl_ClipDistance when a geometry shader is in use. Fixes piglit test spec/glsl-1.50/transform-feedback-type-and-size. v2: Change the type of LastClipDistanceArraySize to "unsigned", and clarify the comment above it.

* i965: Fix gl_MaxCombinedTextureImageUnits.Paul Berry2013-10-241-1/+6
| | | | | | | | | | | | | | | | | | | We've always overriden ctx->Const.{Vertex,Fragment}Program.MaxTextureImageUnits to reflect the number of texture image units supported by the hardware (rather than using the default values assigned by Mesa core) so it seems sensible to do that for GeometryProgram.MaxTextureImageUnits too. We set it to 0 if geometry shaders aren't supported. Once that is done, we can just unconditionally add GeometryProgram.MaxTextureImageUnits to MaxCombinedTextureImageUnits. Fixes piglit test "spec/glsl-1.50/built-in constants/gl_MaxCombinedTextureImageUnits".

* freedreno/a3xx: fix const/rel/const-rel encodingRob Clark2013-10-244-88/+300
| | | | | | | | | | | | | | | | | | | | | | | | The encoding of constant, relative, and relative-const src registers is a bit more complex than originally thought, which gives an extra bit to encode const reg # at expense of taking a bit from relative offset. In most cases a3xx seems to actually use a scheme whereby it can encode an extra bit for const register. You have three possible encodings in thirteen bits: register: (11 bits for N.c) 00........... rN.c relative: (10 bits for N) 010.......... r<a0.x + N> 011.......... c<a0.x + N> const: (12 bits for N.c) 1............ cN.c Which means we can deal w/ more consts than previously thought.

* gallivm: implement fully accurate corner filtering for seamless cube mapsRoland Scheidegger2013-10-251-13/+151
| | | | | | | | | | | | | | | | | | | | | | d3d10 requires that cube corners are filtered with accurate weights (that is, the weight of the non-existing corner texel should be evenly distributed to the other 3 texels). OpenGL does not require this (but recommends it). This requires us to use different filtering code, since we need per-texel weights which our 2d lerp doesn't (and can't) do. And of course the (now per element) weights need to be adjusted too for it to work. Invoke the new filtering code whenever there's an edge to keep things simpler, as it will work for edges too not just corners but of course it's only needed with corners. More ugly code for not much gain but at least a hacked up cubemap demo shows very nice corners now... Not sure yet if and how this should be configurable... v2: incorporate feedback from Jose, only use special corner filtering code when there's a corner not when there's only an edge (as corner filtering code is slower, though a perf difference was only measureable when always forcing edge code). Plus some minor style fixes. Reviewed-by: Jose Fonseca <[email protected]>

* i915: Build the driver into the shared mesa_dri_drivers.so.Eric Anholt2013-10-247-21/+126
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i915 has symbols for formerly-shared code that conflict with i965, so we define them away using gen-symbol-redefs.py. Options considered: - This option. Downsides: The symbols in profiling and debugging don't match the source. The symbol list may change in the future and we won't notice without manually running the tool again. - Use objcopy --localize-hidden to automatically demote our symbols to locals. This didn't work on i965 due to c++ weak symbols (which can't be localized), but could work on i915. We could do it on i915 only, but it does produce libtool warnings at link time due to libtool not knowing if the resulting .o file is safe to link (stupid libtool). Plus you end up with different symbols of the same name, which is confusing for debugging too. On the other hand, no future symbol conflicts long term. - Write our own libelf tool that handles c++ weak symbols like we want and apply it to all drivers. All the downsides of above, but applies uniformly across drivers. - Edit the files to just rename all the i915 or i965 symbols that conflict. There are on the order of 100 that have a prefix we used to share, so it would take a bit of typing. Fewest downsides, but still can have conflicts long term. Ultimately, this is the least invasive change at the moment, and we can see if the "more symbol conflicts appear later" thing is a real concern or not. Note that the ability to compile a version of i915 without INTEL_DEBUG env support is dropped. It's too useful. v2: drop dridir now that it's unused. v3: Consistently put spaces around += in the updated Makefile.am block. v4: Set a global driverAPI variable so loaders don't have to update to createNewScreen2() (though they may want to for thread safety).

| | | | | | | | | | | | | | | | | | | | | | | | | | Previously, we've split things such that mesa core is in libdricore, exposing the whole Mesa core interface in the global namespace, and the i965_dri.so code all links against that. Along with polluting application namespace terribly, it requires extra PLT indirections and prevents LTO. Instead, we can build all of the driver contents into the same .so with just a few symbols exposed to be referenced from the actual driver .so file, allowing LTO and reducing our exposed symbol count massively. FPS improvement on GLB2.7 with INTEL_NO_HW=1: 2.61061% +/- 1.16957% (n=50) (without LTO, just the PLT reductions from this commit) Note that the X Server requires commit 7ecfab47eb221dbb996ea6c033348b8eceaeb893 to successfully load this driver! v2: Set a global driverAPI variable so loaders don't have to update to createNewScreen2() (though they may want to for thread safety). v3: Drop AM_CPPFLAGS addition (Emil pointed out I'd missed some cflags that would be necessary, though only if we actually relied on them). v4: Fix install with DESTDIR set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | In commit 800610f (i965/fs: Improve accuracy of dFdy() to match dFdx()) I unrolled the high-accuracy dFdy() computation from a single SIMD16 instruction to two SIMD8 instructions because of text I found in the i965 (gen4) PRM saying that instruction compression could not be used in align16 mode. I couldn't find similar text in later hardware docs, and I observed problems trying to use instruction compression on align16 mode on Ivy Bridge, so I assumed that the restriction still applied and the associated documentation had simply been lost. After consultation with the hardware engineers, it turns out this is not the case. In point of fact, the restriction was dropped in gen5, re-introduced in Ivy Bridge, and dropped again in Haswell. The reason I didn't notice this is that in the Ivy Bridge documentation, the restriction was in a different section, and described using different language. Now that we know that the restriction only applies to Gen4 and Ivy Bridge, we can limit the unrolling to those platforms. Tested on gen5, gen6, and gen7 (both Ivy Bridge and Haswell).

| | | | | | | | | | | | | | | | | | | | | | | | | | | The unit tests added in the previous commits prove some things about the state of some internal data structures. The most important of these is that all built-in input and output variables have explicit_location set. This means that link_invalidate_variable_locations doesn't need to know the range of non-generic shader inputs or outputs. It can simply reset location state depending on whether explicit_location is set. There are two additional assumptions that were already implicit in the code that comments now document. - ir_variable::is_unmatched_generic_inout is only used by the linker when connecting outputs from one shader stage to inputs of another shader stage. - Any varying that has explicit_location set must be a built-in. This will be true until GL_ARB_separate_shader_objects is supported. As a result, the input_base and output_base parameters to link_invalidate_variable_locations are no longer necessary, and the code for resetting locations and setting is_unmatched_generic_inout can be simplified.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | _mesa_glsl_initialize_variables Checks that the variables generated meet certain criteria. - Vertex shader inputs have an explicit location. - Vertex shader outputs have an explicit location. - Fragment shader-only varying locations are not used. - Vertex shader uniforms and system values don't have an explicit location. - Vertex shader constants don't have an explicit location and are read-only. - No other kinds of vertex variables exist. It does not verify that an specific variables exist. v2: Fix memory management mistakes in common_builtin::string_starts_with_prefix. Clean up error message reporting in common_builtin::no_invalid_variable_modes. Both suggested by Paul. Signed-off-by: Ian Romanick <[email protected]> Reviewed-by: Paul Berry <[email protected]>
