Subject: [PATCH 0/2] Remaining work for PKS Implementation
Date: Fri, 5 Feb 2021 16:33:23 +0800 [thread overview]
Message-ID: <20210205083325.13880-1-chenyi.qiang@intel.com> (raw)
Protection Keys for Supervisor Pages (PKS) is a feature that extends the
Protection Keys architecture to support thread-specific permission
restrictions on superviosr pages, which works similar to an existing
feature named PKU (protecting user-mode pages).
Thanks Paolo to send out the PKS QEMU implemention at:
https://lore.kernel.org/qemu-devel/20210127093540.472624-1-pbonzini@redhat.com/
This patch series is just to add the remaining part, i.e. the support
for save/load PKRS and expose the vmx entry/exit load controls to guest.
