Subject: [PATCH v6 0/3] update live migration configuration region

On the new hardware platform, the configuration register space
of the live migration function is set on the PF, while on the

	Update VF device properties

Change v4 -> v5
	Remove BAR length alignment

Change v3 -> v4
	Rebase on kernel 6.15

Change v2 -> v3
	Put the changes of Pre_Copy into another bugfix patchset.

Change v1 -> v2
	Delete the vf_qm_state read operation in Pre_Copy

Longfang Liu (3):
  migration: update BAR space size
  migration: qm updates BAR configuration
  migration: adapt to new migration configuration
