Subject: [PATCH v9 0/4] debugfs to hisilicon migration driver
Date: Fri, 13 Sep 2024 17:54:58 +0800 [thread overview]
Message-ID: <20240913095502.22940-1-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 v8 -> v9
Added device enable mutex
Changes v7 -> v8
Delete unnecessary information
Changes v6 -> v7
Remove redundant kernel error log printing and
remove unrelated bugfix code
Changes v5 -> v6
Modify log output calling error
Changes v4 -> v5
Adjust the descriptioniptionbugfs file directory
Changes v3 -> v4
Rebased on kernel6.9
Changes 2 -> v3
Solve debugfs serialization problem.
Changes v1 -> v2
Solve the racy problem of io_base.
