Add the drivers/virt directory, which houses drivers that support virtualization environments, and add the Freescale hypervisor management driver.It can't go in linux/virt or linux/virt/fsl instead? why drivers/ ? or maybe linux/virt should be drivers/virt ?See discussion for v2 of this patch. I suggested that drivers/firmware and virt/ as options, the counterarguments were that drivers/firmware is for passive firmware as opposed to firmware that acts as a hypervisor, and that virt/ is for the host side of hypervisors like kvm, not for guests.
OK, I read that thread. Didn't see a real consensus there. If you were not the drivers/misc/ maintainer, would you mind if this driver lived in drivers/misc/? I wouldn't. But it sounds like virt/ needs virt/host/ and virt/guest/ to me.
The driver in here most closely resembles the xen dom0 model, where a priviledged guest controls other guests, but unlike xen there is a single driver file, so there is no need to have drivers/fsl-hv directory just for this one file. We do have a number of other hypervisors that fit in the same category, so they can be added here later.
