X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=a4c6d5d146157228bc03429cf7926d8a14072c84;p=thirdparty%2Fkernel%2Flinux.git

gpu: nova-core: enable GA100

GA100 is a compute-only variant of GA102 that boots GSP-RM like a
Turing, although it also has its own unique requirements.

Now that all the pieces are in place, we can enable GA100 support.
Although architecturally like an Ampere, GA100 uses the same GSP-RM
firmware files as Turing, and therefore must boot it like Turing does.
However, as a compute-only part, GA100 has no display engine.
