devlink: Add support for region snapshot read command

2018-07-13T00:37:13Z

Add support for DEVLINK_CMD_REGION_READ_GET used for both reading and dumping region data. Read allows reading from a region specific address for given length. Dump allows reading the full region. If only snapshot ID is provided a snapshot dump will be done. If snapshot ID, Address and Length are provided a snapshot read will done. This is used for both snapshot access and will be used in the same way to access current data on the region. Signed-off-by: Alex Vesker Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

Extend the support for DEVLINK_CMD_REGION_GET command to also return the IDs of the snapshot currently present on the region. Each reply will include a nested snapshots attribute that can contain multiple snapshot attributes each with an ID. Signed-off-by: Alex Vesker Signed-off-by: Jiri Pirko Signed-off-by: David S.

devlink: Add support for region get command

2018-07-13T00:37:13Z

Add support for DEVLINK_CMD_REGION_GET command which is used for querying for the supported DEV/REGION values of devlink devices. The support is both for doit and dumpit. Reply includes: BUS_NAME, DEVICE_NAME, REGION_NAME, REGION_SIZE Signed-off-by: Alex Vesker Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

devlink: Add support for creating region snapshots

2018-07-13T00:37:13Z

Each device address region can store multiple snapshots, each snapshot is identified using a different numerical ID. This ID is used when deleting a snapshot or showing an address region specific snapshot. This patch exposes a callback to add a new snapshot to an address region. The snapshot will be deleted using the destructor function when destroying a region or when a snapshot delete command from devlink user tool.

devlink: Add callback to query for snapshot id before snapshot create

2018-07-13T00:37:12Z

To restrict the driver with the snapshot ID selection a new callback is introduced for the driver to get the snapshot ID before creating a new snapshot. This will also allow giving the same ID for multiple snapshots taken of different regions on the same time. Signed-off-by: Alex Vesker Signed-off-by: Jiri Pirko Signed-off-by: David S. Miller

devlink: Add support for creating and destroying regions

2018-07-13T00:37:12Z

This allows a device to register its supported address regions. Each address region can be accessed directly for example reading the snapshots taken of this address space. Drivers are not limited in the name selection for different regions. An example of a region-name can be: pci cr-space, register-space.
