Hi, Glaze We’re discussing it in another thread. I have added you into that mail thread. Your comments is always welcomed. Min From: dionnaglaze via groups.io Sent: Wednesday, June 15, 2022 12:10 AM To: Xu, Min M ; devel@edk2.groups.io Subject: Re: [edk2-devel] [PATCH 07/14] OvmfPkg: Add PCD and DEFINEs for Lazy Accept page. Since there will be guest OSes that don't support unaccepted memory type (at least initially), and what will be run won't be known at firmware build time, can PcdLazyAcceptPartialMemorySize be initialized by a QemuFwCfg option instead of a FixedPcd? I started a different thread on this, but perhaps it was lost.
