* docs: Document shader capturing environment variables.Kenneth Graunke2017-09-121-0/+15

* docs: removed the '--with-sha1' requirement from shading.htmlEleni Maria Stea2017-08-071-3/+3
| | | | | | | | | | | | The configuration option --with-sha1 is no longer required for the MESA_SHADER_READ_PATH, MESA_SHADER_DUMP_PATH environment variables to take effect. 1- removed the "--with-sha1" sentence from docs/shading.html 2- added an extra note: that the corresponding dumped and replacement shaders must have the same filenames for the feature to take effect.

* mesa: add an env var to force cache fallbackTimothy Arceri2017-05-201-0/+2
| | | | | | | | | | | | | | | | | 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.

* mesa: remove MESA_GLSL=no_opts env optionTimothy Arceri2017-03-311-1/+0
| | | | | | | | | | | | This is confusing because is only applys to GL_ARB_vertex/fragment_program, and because of that its also not very useful. If someone requires this for debugging they can just make an ad-hoc code change.

| | | | | | | | | Most of them already redirected to https anyway, so we might as well avoid the redirection and the security implications by linking directly to the right protocol. Signed-off-by: Eric Engestrom <[email protected]> Reviewed-by: Brian Paul <[email protected]>

* docs: Fix GLSL compiler linkElie TOURNIER2017-01-181-4/+8
| | | | | | | | | | | | | | The doc wasn't update since we moved the glsl compiler to src/compiler/glsl. I also updated the description of the standalone compiler. v2: - Mention that just-log argument removes headers/separators. - Mention that version argument is mandatory. Since version argument is mandatory, add --version to the command line example. Signed-off-by: Elie Tournier <[email protected]> Reviewed-by: Alejandro Piñeiro <[email protected]>

* mesa: change 'SHADER_SUBST' facility to work with env variablesTapani Pälli2015-09-041-0/+14
| | | | | | | | | | | | | | | | | | | Patch modifies existing shader source and replace functionality to work with environment variables rather than enable dumping on compile time. Also instead of _mesa_str_checksum, _mesa_sha1_compute is used to avoid collisions. Functionality is controlled via two environment variables: MESA_SHADER_DUMP_PATH - path where shader sources are dumped MESA_SHADER_READ_PATH - path where replacement shaders are read v2: cleanups, add strerror if fopen fails, put all functionality inside HAVE_SHA1 since sha1 is required Signed-off-by: Tapani Pälli <[email protected]> Suggested-by: Eero Tamminen <[email protected]> Reviewed-by: Brian Paul <[email protected]>
