Subject: [Patch 1/7] UefiCpuPkg/CpuDxe: Fix duplicated status code report
Date: Fri, 9 Sep 2016 15:59:27 +0800 [thread overview]
Message-ID: <20160909075933.14320-2-jeff.fan@intel.com> (raw)
In-Reply-To: <20160909075933.14320-1-jeff.fan@intel.com>
If CPU Bist data is not zero, we will report Status code. But there is one bug
that will report each processor's status code duplicated with NumberOfData
times. This fix is to exchange the loop order on NumberOfData and
mNumberOfProcessors. It could make sure the report status code only once for
each processor.
