[PATCH 00/15] Support POWER8 and little-endian guests in HV KVM

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch series adds basic POWER8 support and support for
little-endian guests to HV KVM.  The last patch implements support for
the H_SET_XDABR hcall for POWER7 guests.  The series is against the
'next' branch of the kvm tree as of a couple of days ago, plus the two
bug-fix patches I posted recently ("Fix physical address calculations"
and "Refine barriers in guest entry/exit").

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 include the support for saving and restoring the
transactional checkpointed state of the guest.  For that, I need Ben's
for-kvm branch to be merged to bring in the "powerpc: Put FP/VSX and
VR state into structures" patch.

Paul.
