Subject: [patch 3/3] MdeModulePkg/PeiPerformancePpiLib: Add PeiPerformancePpiLib
Date: Mon, 30 Jul 2018 14:59:05 +0800 [thread overview]
Message-ID: <20180730065905.9152-4-dandan.bi@intel.com> (raw)
In-Reply-To: <20180730065905.9152-1-dandan.bi@intel.com>
Add a new "thin" PerformanceLib instance
PeiPerformancePpiLib which will locate a
Performance measurement Ppi to log performance data.
Platform can link the "thin" PeiPerformancePpiLib
to log the performance data for PEIMs.
It also can link the PeiPerformanceLib in PEI phase
to keep the compatibility.
