| | | | | | | | | | Not used since ages, and it wouldn't work at all with explicit derivatives now (not that it did before as it ignored them but now the code would just use the derivs pre-projected which would be quite random numbers). v2: also get rid of 3 helper functions no longer used.

* gallivm: handle explicit derivatives for cubemapsRoland Scheidegger2013-10-103-56/+235
| | | | | | | | | | | | | | | | | | | | They need some special handling. Quite complicated. Additionally, use the same code for implicit derivatives too if no_rho_approx and no_quad_lod is set, because it seems while generally it should be ok to use per quad lod for implicit derivatives there's at least some test which insists that in case of cubemaps the shared lod value MUST come from a pixel inside the primitive (due to the derivatives becoming different if a different larger major axis is chosen). v2: based on Brian's feedback, clean up code a bit. And use sign bit of major axis instead of pre-select s/t/r sign for coord mirroring (which should be the same in the end, saves 2 ands). Also fix two bugs with select/mirror of derivatives, the minor axes need to use major axis sign as well (instead of major derivative axis sign), and don't mistakenly use absolute values of major derivative and inverse major values.

* gallivm: ignore rho approximation for cube mapsRoland Scheidegger2013-10-101-30/+20
| | | | | | | | | | | | | | There's two reasons for this: 1) even when ignoring rho approximation for cube maps, the result is still not correct, but it's better as the max error at edges is now sqrt(2) instead of 2 (which was a full mip level), same as it is for ordinary 2d maps when doing rho approximations (so the error actually goes from factor 2 at edges and sqrt(2) completely inside a face to sqrt(2) at edges and 0 inside a face). 2) I want to repurpose rho_no_approx for cubemaps for fully correct cubemap derivatives (so don't need yet another debug var).

* glsl: Modify array_sizing_visitor to handle unnamed interface blocks.Paul Berry2013-10-092-2/+88
| | | | | | | | | | | | | | | | | | | We were already setting the array size of unsized arrays that appeared inside unnamed interface blocks, but we weren't updating ir_variable::interface_type to reflect the new array size, causing bogus link errors. This patch causes array_sizing_visitor to keep track of all the unnamed interface types it sees, and the ir_variables corresponding to each one. After the visitor runs, a new function, fixup_unnamed_interface_types(), adjusts each unnamed interface type to correctly correspond with the array sizes in the ir_variables.

* i965/blorp: Allow format conversions for CopyTexSubImage.Kenneth Graunke2013-10-091-1/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | BLORP performs blits by drawing a rectangle with a shader that samples from the source texture, and writes color data to the destination. The sampler always returns 32-bit RGBA float data, regardless of the source format's component ordering or data type. Likewise, the render target write message takes 32-bit RGBA float data, and converts it appropriately. So the bulk of the work is already taken care of for us. This greatly accelerates a lot of CopyTexSubImage calls, and makes Legends of Aethereus playable on Ivybridge. At the default settings, LOA continually blits between SRGBA8888 (the window format) and RGBA16_FLOAT. Since neither BLORP nor our BLT paths supported this, it fell back to meta, spending 33% of the CPU in floorf() converting between floats and half-floats. v2: Use != instead of ^ (suggested by Ian). Note that only CopyTexSubImage is affected by this patch (caught by Eric).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous code for sRGB overrides assumes that the source and destination formats are equal, other than the color space. This won't be feasible when we add support for format conversions. Here are a few cases, and how the old code handled them: 1. RGB8 -> SRGB8, MSAA ==> SRGB8 -> SRGB8 2. RGB8 -> SRGB8, single ==> RGB8 -> RGB8 3. SRGB8 -> RGB8, MSAA ==> RGB8 -> RGB8 4. SRGB8 -> RGB8, single ==> SRGB8 -> SRGB8 Apparently, preserving the behavior of #1 is important. When doing a multisample to single-sample resolve, blending the samples together in an sRGB correct fashion results in a noticably higher quality image. It also is necessary to pass Piglit's EXT_framebuffer_multisample accuracy color tests. Paul, Eric, Anuj, and I talked about this, and aren't sure that it matters in the other cases. This patch preserves the behavior of #1, but otherwise reverts to doing everything in linear space, changing the behavior of case #4.

* i965/blorp: Add support for non-render-target formats.Kenneth Graunke2013-10-091-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Once blorp gains the ability to do format conversions, it's conceivable that the source format may be texturable but not supported as a render target. This would break Paul's code, which assumes that it can use the render_target_format array even for the source format. There are three ways to convert MESA_FORMAT enums to BRW_SURFACEFORMAT enums: 1. brw_format_for_mesa_format() This translates the Mesa format to the most equivalent BRW format. 2. brw->render_target_format[] This is used for renderbuffers, and handles the subset of formats that are renderable. However, it's not always equivalent, since it overrides a few non-renderable formats. For example, it converts B8G8R8X8_UNORM to B8G8R8A8_UNORM so it can be rendered to. 3. translate_tex_format() This is used for textures. It wraps brw_format_for_mesa_format(), but overrides depth textures, and one sRGB case on Gen4. BLORP has a fourth function, which uses brw->render_target_format[] and overrides depth formats (differently than translate_tex_format). This patch makes the BLORP function to use brw_format_for_mesa_format() for textures/source data, since not everything will be a render target. It continues using brw->render_target_format[] for render targets, since it needs the format overrides that provides. We don't use translate_tex_format() since the additional overrides are not useful or simply redundant.

* i965/gs: Fixup gl_PointSize on entry to geometry shaders.Paul Berry2013-10-081-0/+17
| | | | | | | | | | | | | | | | gl_PointSize is stored in the w component of VARYING_SLOT_PSIZ, but the geometry shader infrastructure assumes that it should look for all geometry shader inputs of type float in the x component. So when compiling a geomtery shader that uses a gl_PointSize input, fix it up during the shader prolog by moving the w component to the x component. This is similar to how we emit fixups and workarounds for vertex shader attributes. Fixes piglit test spec/glsl-1.50/execution/geometry/core-inputs.
