Flatview will make sure that we don't have to deal with overlapping slots. E.g. when a memory section is resized, we are first notified about the removal and then about the new memory section. So basically, we can directly always map one memory section to one kvm slot (if the fixed up size is > 0). RFC -> v1: - minor changes to avoid changing indentation, therefore making it easier to review David Hildenbrand (6): kvm: require JOIN_MEMORY_REGIONS_WORKS kvm: factor out alignment of memory section kvm: use start + size for memory ranges kvm: we never have overlapping slots in kvm_set_phys_mem() kvm: kvm_log_start/stop are only called with known sections kvm: kvm_log_sync() is only called with known memory sections accel/kvm/kvm-all.c | 235 +++++++++++++++------------------------------------- 1 file changed, 68 insertions(+), 167 deletions(-) -- 2.13.5
