Subject: [PATCH v2 00/30] Port of KVM to arm64
Date: Tue, 26 Mar 2013 17:00:55 +0000 [thread overview]
Message-ID: <1364317285-20937-1-git-send-email-marc.zyngier@arm.com> (raw)
This series contains the second version of KVM for arm64. It depends
on the "pre-arm64 rework" series I posted initially (already in RMK's
tree), the tiny perf patch sent just after (already in Christoffer's
tree), and yet another 32bit rework patch ("ARM: KVM: promote vfp_host
pointer to generic host cpu context").
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
Testing has been done on both AEMv8 and Foundation models, with
various 32 and 64bit guests running a variety of distributions (OE,
Ubuntu and openSUSE for 64bit, Debian and Ubuntu on 32bit).
The patches are also available on the following branch:
git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git kvm-arm64/kvm
As we do not have a 64bit QEMU port, it has been tested using
kvmtools. Note that some of the changes have broken the userspace
ABI, and you must update and rebuild your kvmtools (the previous
version won't work anymore):
git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms.git kvm-arm64/kvmtool
>From v1:
- Rework of the world-switch to use common structure between host and
guests (suggested by Christopher Covington)
- Some additional constants to make the EL1 fault injection clearer
(suggested by Christopher Covington)
- Use of __u64 instead of "unsigned long" in the userspace API
(suggested by Michael S. Tsirkin)
- Move the FP/SIMD registers into the "core" registers, dropping the
specific accessors.
- Generic MPIDR implementation (suggested by Christopher Covington)
- Cleaner handling of the various host implementation
