* mesa: add an env var to force cache fallbackTimothy Arceri2017-05-203-1/+8
| | | | | | | | | | | | | | | | | For the gallium state tracker a tgsi binary may have been evicted from the cache to make space. In this case we would take the fallback path and recompile/link the shader. On i965 there are a number of reasons we can get to the program upload stage and have neither IR nor a valid cached binary. For example the binary may have been evicted from the cache or we need a variant that wasn't previously cached. This environment variable enables us to force the fallback path that would be taken in these cases and makes it easier to debug these otherwise hard to reproduce scenarios.

* st/mesa: improve shader cache debug infoTimothy Arceri2017-05-201-2/+4
| | | | | | | | | | | This will explicitly state that we are following the fallback path when we find invalid/corrupt cache items. It will also output the fallback message when the fallback path is forced via an environment variable, the following patches will allow this.

* i965/formats: Update the three-channel DXT1 mappingsNanley Chery2017-05-182-14/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The procedure for decompressing an opaque DXT1 OpenGL format is dependant on the comparison of two colors stored in the first 32 bits of the compressed block. Here's the specified OpenGL behavior for reference: The RGB color for a texel at location (x,y) in the block is given by: RGB0, if color0 > color1 and code(x,y) == 0 RGB1, if color0 > color1 and code(x,y) == 1 (2*RGB0+RGB1)/3, if color0 > color1 and code(x,y) == 2 (RGB0+2*RGB1)/3, if color0 > color1 and code(x,y) == 3 RGB0, if color0 <= color1 and code(x,y) == 0 RGB1, if color0 <= color1 and code(x,y) == 1 (RGB0+RGB1)/2, if color0 <= color1 and code(x,y) == 2 BLACK, if color0 <= color1 and code(x,y) == 3 The sampling operation performed on an opaque DXT1 Intel format essentially hard-codes the comparison result of the two colors as color0 > color1. This means that the behavior is incompatible with OpenGL. This is stated in the SKL PRM, Vol 5: Memory Views: Opaque Textures (DXT1_RGB) Texture format DXT1_RGB is identical to DXT1, with the exception that the One-bit Alpha encoding is removed. Color 0 and Color 1 are not compared, and the resulting texel color is derived strictly from the Opaque Color Encoding. The alpha channel defaults to 1.0. Programming Note Context: Opaque Textures (DXT1_RGB) The behavior of this format is not compliant with the OGL spec. The opaque and non-opaque DXT1 OpenGL formats are specified to be decoded in exactly the same way except the BLACK value must have a transparent alpha channel in the latter. Use the four-channel BC1 Intel formats with the alpha set to 1 to provide the behavior required by the spec. Note that the alpha is already set to 1 for RGB formats in brw_get_texture_swizzle(). v2: Provide a more detailed commit message (Kenneth Graunke). v3: Ensure the alpha channel is set to 1 for DXT1 formats.

* st/mesa: remove an incorrect assertionNicolai Hähnle2017-05-181-2/+0
| | | | | | | | | | | There is really no reason why the current DrawBuffer needs to be complete at this point. In particular, the assertion gets hit on the X server side in libglx when running .../piglit/bin/glx-get-current-display-ext -auto (which uses indirect GLX rendering).

| | | | | | | | | | | | | | | | | | | Commit 6facb0c0 ("android: fix libz dynamic library dependencies") unconditionally adds libz as a dependency to all shared libraries. That is unnecessary. Commit 85a9b1b5 introduced libz as a dependency to libmesa_util. So only the shared libraries that use libmesa_util need libz. Fix Android Lollipop build by adding the include path of zlib to libmesa_util explicitly instead of getting the path implicitly from zlib since it doesn't export the include path in Lollipop.
