[PATCH 00/29] Port of KVM to arm64

Marc Zyngier
2013-03-05T03:47:59Z

This series contains the implementation of KVM for arm64. It depends
on the "pre-arm64 rework" series I posted earlier, as well as on the
tiny perf patch sent just after.

The code is unsurprisingly extremely similar to the KVM/arm code, and
a lot of it is actually shared with the 32bit version. Some of the
include files are duplicated though (I'm definitely willing to fix
that).

In terms of features:
- Support for 4k and 64k pages
- Support for 32bit and 64bit guests
- PSCI support for SMP booting

As we do not have a 64bit QEMU port, it has been tested using kvmtool
(support has already been merged).
