[PATCH v5 0/5] add debugfs to migration driver
by Longfang Liu 04 Jan '23

04 Jan '23

Add a debugfs function to the migration driver in VFIO to provide a step-by-step test function for the migration driver. 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 v4 -> v5 Remove the newly added vfio_migration_ops and use seq_printf to optimize the implementation of debugfs. Changes v3 -> v4 Change the migration_debug_operate interface to debug_root file. Changes v2 -> v3 Extend the debugfs function from hisilicon device to vfio. Changes v1 -> v2 Change the registration method of root_debugfs to register with module initialization.
