Subject: Re: [Patch v2 2/2] UefiCpuPkg/RegisterCpuFeaturesLib: avoid use dynamic PCD.
Date: Mon, 15 Jul 2019 10:03:10 +0000 [thread overview]
Message-ID: <0C09AFA07DD0434D9E2A0C6AEB04831040365A5F@shsmsx102.ccr.corp.intel.com> (raw)
In-Reply-To: <20190715070056.25916-3-eric.dong@intel.com>
IsBitMaskMatchCheck() is still using PcdGetSize (PcdCpuFeaturesSetting).
Compared to V1 patch, I guess the patch wants to
1. add BitMaskSize input parameter for IsCpuFeatureMatch().
2. use GetCpuFeaturesData () in IsBitMaskMatchCheck().
Right?
Thanks,
Star
