commit can optimize the downtime. But we observed
that the dirty log stop cannot be executed if user inputs "quit" in qemu
monitor after migration completes. Have you considered such case before?
Any suggestion? Thanks!

Skip this notification but not coredump makes everything
work well.

Should directly read DMAR_RTADDR_REG but not using 's->root'.
Because 's->root' is modified in 'vtd_root_table_setup()' so
that the first 12 bits are omitted. This causes the guest
iommu debugfs cannot show pasid tables.

scenario to break migration? From latest
qemu integrated scalable mode patches to an old qemu without scalable
mode?
The changes look good to me. Thanks for the fix!

- revert unnecessary rename in 'vtd_ce_present".
- use 'ce_size' to judge if it is scalable mode in
ace_vtd_replay_ce_valid'.
Patch 2:
- do "(val & VTD_IQT_QT_256_RSV_BIT)" to be clear.
Patch 3:
- move 's->dma_drain' check from 'vtd_init' to 'vtd_decide_config'.

- rename "scalable-mode" to "x-scalable-mode".
- remove caching_mode check when scalable_mode is set.
- check dma_drain check when scalable_mode is set. This is requested
by spec.
- remove redundant macros.
