Subject: iris: Expose the disk cache to the state tracker as well.
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=fb1d08dcfd53cad8d933592c4515a9dc123376e3;p=mesa.git

iris: Expose the disk cache to the state tracker as well.

This lets st/nir cache the NIR for shaders, based on the shader source
string hash, allowing us to skip initial compiles altogether, and also
letting us start from there should we need to recompile for NOS.
