bugzilla: https://gitee.com/openeuler/kernel/issues/I9QBDS
CVE: NA
----------------------------------------------------------------------
Support using the HDBSS feature during live migration.
Hardware Dirty state tracking Structure(HDBSS) enhances tracking
translation table descriptors’ dirty state to reduce the cost of
surveying for dirtied granules.
The HDBSS enabling time and HDBSS buffer size are controlled by
QEMU.

From: eillon <yezhenyu2(a)huawei.com>
Support using the HDBSS feature during live migration.
Hardware Dirty state tracking Structure(HDBSS) enhances tracking
translation table descriptors’ dirty state to reduce the cost of
surveying for dirtied granules.
The HDBSS enabling time and HDBSS buffer size are controlled by
QEMU.
