> Subject: [edk2-devel] [PATCH v2 3/3] UefiCpuPkg/MtrrLib: Remove
> unnecessary API MtrrSetFixedMtrr()
>
> MtrrSetFixedMtrr() sets all the fixed MTRR settings.
> But in fact MtrrSetAllMtrrs() is always used by callers to set all MTRR
> settings
> including the fixed and variable ones.
>
> The patch removes the necessary API MtrrSetFixedMtrr() to simplify the
> MtrrLib API.
>
> There is no code in edk2 and edk2-platforms repo that calls
> MtrrGetVariableMtrr().
