X-Git-Tag: v6.18-rc1~82^2~39
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ebc68a3451ce419fe2e7a7d3f06df408fb36399e;p=thirdparty%2Flinux.git

platform/x86/amd/pmf: Extend custom BIOS inputs for more policies

The existing amd_pmf driver is limited to supporting just two custom BIOS
inputs. However, with the updates to the latest PMF TA, there's a
requirement to broaden this capacity to handle 10 inputs, aligning with
the TA firmware's capabilities.

The necessary logic should be implemented to facilitate this expansion of
functionality.
