Subject: [Patch V5 14/22] UefiCpuPkg/CpuPageTableLib: Add OUTPUT IsModified parameter.
Date: Fri, 24 Mar 2023 14:00:12 +0800 [thread overview]
Message-ID: <20230324060020.940-15-dun.tan@intel.com> (raw)
In-Reply-To: <20230324060020.940-1-dun.tan@intel.com>
Add OUTPUT IsModified parameter in PageTableMap() to indicate
if page table has been modified. With this parameter, caller
can know if need to call FlushTlb when the page table is in CR3.
