[Mesa-dev] [PATCH 00/17] i965 ARB_get_program_binary support

[Jordan Justen]

git://people.freedesktop.org/~jljusten/mesa i965-get-program-binary-v1

This series adds i965 support for ARB_get_program_binary with greater
than 0 supported formats. Today we support this extension, but
advertise support for 0 formats. This series allows i965 to advertise
support for 1 format.

This series defines a common Mesa format for ARB_get_program_binary,
along with helper functions to read and write the format. We also
define an OpenGL Mesa spec to be used with this binary format. The
binary saved can only be reloaded on the exact same Mesa build using
the exact same hardware.

The i965 implementation saves out a serialize nir represenation of the
program. Later we can add support for saving the gen binary program as
well. (We will still need the nir program for state based recompiles.)

This implementation passes piglit, deqp and glcts functions. It also
works with Dota 2, which appears to make use of the extension.
