For the incoming mapped-ram migration we need to read the ramblock headers, get the pages bitmap and send the host address of each non-zero page to the multifd channel thread for writing. Usage on HMP is: (qemu) migrate_set_capability multifd on (qemu) migrate_set_capability mapped-ram on (qemu) migrate_incoming file:migfile (the ram.h include needs to move because we've been previously relying on it being included from migration.c. Now file.h will start including multifd.h before migration.o is processed) Reviewed-by: Peter Xu <peterx@redhat.com> Signed-off-by: Fabiano Rosas <farosas@suse.de> Link: https://lore.kernel.org/r/20240229153017.2221-22-farosas@suse.de Signed-off-by: Peter Xu <peterx@redhat.com>
