Subject: [PATCH 0/3] Allow SMM access-out when static paging is OFF
Date: Sat, 27 Jul 2019 11:28:47 +0800 [thread overview]
Message-ID: <20190727032850.337840-1-ray.ni@intel.com> (raw)
The patch set refines the original CR2 save/restore logic by adding
a new internal function IsStaticPageTableEnabled() because now
there are two use cases that need to conditionally do something
based on whether static page table is enabled.
Based on the refine, the patch changes the policy to allow SMM access
out when static paging is OFF.
