Revised iteration after initial comments. Still just for ARMv7. I looked
at the ARMv8 code and yes it practically appears to reuse most of
fault handling in ARMv7, I wasn't aware so much code was in common.
But before then want to make sure it's reliable on real hardware.
This patch adds support for ARMv7 Live Migration, primarily dirty bit map
management is added. The patch follows the normal migration flow managed by
user space, first write protecting the entire address space and later
keeping track of dirty pages. In the process of initial write protection,
and first time faults huge pages are broken up into small pages to support
migration on loaded systems.
Mario Smarduch (5):
add ARMv7 HYP API to flush VM TLBs without address param
live migration support for initial write protect of VM to manage
dirty pages
live migration support for VM dirty log management
add 2nd stage page fault handling during live migration
add kvm_arch glogal live migration variable
