From: Daniele Ceraolo Spurio Date: Tue, 21 Jun 2022 23:30:05 +0000 (-0700) Subject: drm/i915/guc: ADL-N should use the same GuC FW as ADL-S X-Git-Tag: v6.1-rc5~870^2~9 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=1391b9cfd35bb8f10785a17cb4bb5ea8d10faaae;p=platform%2Fkernel%2Flinux-starfive.git drm/i915/guc: ADL-N should use the same GuC FW as ADL-S The only difference between the ADL S and P GuC FWs is the HWConfig support. ADL-N does not support HWConfig, so we should use the same binary as ADL-S, otherwise the GuC might attempt to fetch a config table that does not exist. ADL-N is internally identified as an ADL-P, so we need to special-case it in the FW selection code.
