Subject: [PATCH v4 0/4] add debugfs to hisilicon migration driver
Date: Tue, 2 Apr 2024 11:24:28 +0800	[thread overview]
Message-ID: <20240402032432.41004-1-liulongfang@huawei.com> (raw)

Add a debugfs function to the hisilicon migration driver in VFIO to
provide intermediate state values and data during device migration.

When the execution of live migration fails, the user can view the
status and data during the migration process separately from the
source and the destination, which is convenient for users to analyze
and locate problems.

Changes v3 -> v4
	Rebased on kernel6.9

Changes v2 -> v3
	Solve debugfs serialization problem.

Changes v1 -> v2
	Solve the racy problem of io_base.
