[Mesa-dev] [v2 0/4] RFC: gl_shader cache v2

[Tapani Pälli]

Hi;

This is version 2 of the shader cache patches. I've fixed issues with
Lightsmark and Warsow that the first series had, I was not simply caching
enough information for reconstructing ir_variables correctly. Internal API
has some changes and data is now first written to memory and then dumped
as a whole to disk. I also added '--enable-shadercache' configure option
that needs to be used for getting the cache functionality. It might make
also sense to support environment variables that Nvidia driver has for
their cache (__GL_SHADER_DISK_CACHE and __GL_SHADER_DISK_CACHE_PATH) (?)

Currently I'm working on fixing remaining Piglit issues. When I get Piglit
fully passing I will start to work on OES_get_program_binary extension
implementation that utilizes this ir_cache.

If you want to test this, Mesa tree with patches on top is available here:
