From db91c6208244681fdcad4a4800ebdd3c05aaf3c0 Mon Sep 17 00:00:00 2001 From: lzeng14 Date: Thu, 16 May 2013 07:35:30 +0000 Subject: [PATCH] Separate memory allocation for FPDT S3 performance table and boot performance table, save S3 performance table pointer to LockBox in FirmwarePerformanceDxe. Then FirmwarePerformancePei can use the pointer in LockBox.
