Hi,
This is an experimental set that reworks the way the vhost
code handles changes in physical address space layout that
came from a discussion with Igor.
Instead of updating and trying to merge sections of address
space on each add/remove callback, we wait until the commit phase
and go through and rebuild a list by walking the Flatview of
memory and end up producing an ordered list.
We compare the list to the old list to trigger updates.
Note, only very lightly tested so far, I'm just trying to see if it's
the right shape.
Igor, is this what you were intending?
Dave
Dr. David Alan Gilbert (7):
memory: address_space_iterate
vhost: Move log_dirty check
vhost: New memory update functions
vhost: update_mem_cb implementation
vhost: Compare new and old memory lists
vhost: Copy updated region data into device state
vhost: Remove vhost_set_memory and children
