Hello,
This patch series adds support for ARMv7 processors (Cortex-A15) to kvm
tool. The majority of the series consists of small changes in
preparation for ARM support, which is added by the final patch. I can
try to split this up further, but given that there is no current support
for ARM, the sub-patches wouldn't be especially meaningful.
To boot a guest, you will need:
- A Cortex-A15 platform with a kvm-capable bootloader
- The latest kvm-arm patches:
git://github.com/virtualopensystems/linux-kvm-arm.git kvm-arm-master
- A guest kernel configured for our virtual target:
git://git.kernel.org/pub/scm/linux/kernel/git/will/kvmtool.git kvm/mach-virt
I'm also working on an ARMv8 (AArch64) port which fits neatly into the
code presented here.
All feedback welcome,
Will
