Subject: gpu: nova-core: add support for Turing/GA100 fwsignature
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=121ea04cd9f22ae8fb405d4929f6a7faefefe553;p=thirdparty%2Fkernel%2Flinux.git

gpu: nova-core: add support for Turing/GA100 fwsignature

Turing and GA100 share the same GSP-RM firmware binary, but the
signature ELF section is labeled either ".fwsignature_tu10x" or
".fwsignature_tu11x".
