Subject: [PATCH 0/5] expire the use of PcdSetNxForStack
Date: Tue, 11 Sep 2018 13:16:31 +0800 [thread overview]
Message-ID: <20180911051636.4888-1-jian.j.wang@intel.com> (raw)
BZ#: https://bugzilla.tianocore.org/show_bug.cgi?id=1116
Since the stack memory is allocated as EfiBootServicesData, its NX protection
can be covered by BIT4 of PcdDxeNxMemoryProtectionPolicy. To avoid confusing
in setting related PCDs, PcdSetNxForStack will be expired. Instead, If BIT4
of PcdDxeNxMemoryProtectionPolicy is set, the DxeIpl will set NX bit in page
table entries mapping the stack memory.
