[RFC] KVM/arm64, take #3

[RFC] KVM/arm64, take #3

[Marc Zyngier]

Guys,

I've once more updated the branches for KVM/arm64

- kvm-arm/pre-arm64: kvm-arm-master as of today + the "cleanup" branch +
some basic perf support

- arm64/soc-armv8-model: Catalin Marinas' arm64 branch

- arm64/psci: Implementation of PSCI for the above

- arm64/perf: host/guest discrimination

- kvm-arm64/kvm-prereq: a bunch of random bits that KVM/arm requires to
compile on arm64.

- kvm-arm64/kvm-prereq-merged: all the above, plus Mark Rutland's timer
rework.

- kvm-arm64/kvm: KVM/arm64 itself, and the only branch you should use
unless you're completely hatstand.

All that is at:
git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git

You'll also need Will Deacon's KVM Tool port:
git://git.kernel.org/pub/scm/linux/kernel/git/will/kvmtool.git kvmtool/arm


A few random notes:
- If you're using the Foundation Model, use the provided DTS for your
host kernel (arch/arm64/boot/dts/foundation-v8.dts).
- The only supported models are the AEMv8 and the Foundation models. If
you're using something else and have any issue, first reproduce it with
one of the supported implementations.

What's new:
- Rebased on 3.8-rc4
- Resynced with kvm-arm-master
- More 32bit fixes (ThumbEE, check for lack of 32bit support in HW)
- Some basic perf support

Enjoy,

	M.

Hi Pranav,

Hmmm...

root@hot-poop:~# dmesg | head
Initializing cgroup subsys cpu
Linux version 3.8.0-rc4+ (maz@e102391-lin) (gcc version 4.7.1 (0.11.114) ) #761 SMP PREEMPT Wed Jan 23 11:43:41 GMT 2013
CPU: AArch64 Processor [410fd000] revision 0
Machine: Foundation-v8A
^^^^^^^^^^^^^^^^^^^^^^^

Seems to be booting well enough for me. Are you sure you used the supplied DT
(as mentioned in the below email)?

There is no need for a platforms directory any more. The vexpress support is
now just a configuration option.
