SVE Reviews
~~~~~~~~~~~

- started reviewing {RFC PATCH 00/16} KVM: arm64: Initial support for
SVE guests Message-Id:
<1529593060-542-1-git-send-email-***@arm.com>


QEMU ARMv8.3 Support ([VIRT-241])
=================================

- added remaining v8.1 stories to JIRA and re-organised under
- [ARMv8.1 Mandatory Features] and [ARMv8.1 optional features]
- pondering how much effort to do VHE
- it's mostly conditional re-direction of EL1/EL2 registers so
host kernel can pretend it's in EL1 when really in EL2
- some EL2 registers present slightly different formats when VHE
bit is set
