If there is still room on the agenda, I would like to get an agreement
on the best way to deal with the Hypervisor mode - (1) start the kernel
in Hyp mode or (2) have a standard HVC API in the board firmware to
allow Linux (KVM, Xen) to take control of the Hyp mode. This could fit
under the boot architecture discussion.
For (1), it could be problematic as the boot loader (e.g. U-Boot) needs
to be aware of the Hyp mode. The 2nd variant may be better but the API
needs to be kept very simple.
I know that neither KVM nor Xen for ARM are supported in the mainline
kernel but silicon vendors are already working on Cortex-A15 platforms
and it would be good if their firmware supports Linux virtualisation.
