Subject: [RFC PATCH 0/10] Support POWER8 in HV KVM
Date: Fri, 06 Sep 2013 03:48:20 +0000 [thread overview]
Message-ID: <20130906034820.GM29710@iris.ozlabs.ibm.com> (raw)
This series adds support for the POWER8 CPU in HV KVM. POWER8 adds
several new guest-accessible instructions, special-purpose registers,
and other features such as doorbell interrupts and hardware
transactional memory. It also adds new hypervisor-controlled features
such as relocation-on interrupts, and replaces the DABR/DABRX
registers with the new DAWR/DAWRX registers with expanded
capabilities. The POWER8 CPU has compatibility modes for architecture
2.06 (POWER7/POWER7+) and 2.05 (POWER6).
This series does not yet handle the checkpointed register state of
the guest.
