devlink: Introduce PCI VF port flavour and port attribute

2019-07-09T19:02:13+00:00

In an eswitch, PCI VF may have port which is normally represented using a representor netdevice. To have better visibility of eswitch port, its association with VF, and its representor netdevice, introduce a PCI VF port flavour. When devlink port flavour is PCI VF, fill up PCI VF attributes of the port. Extend port name creation using PCI PF and VF number scheme on best effort basis, so that vendor drivers can skip defining their own scheme. $ devlink port show pci/0000:05:00.0/0: type eth netdev eth0 flavour pcipf pfnum 0 pci/0000:05:00.0/1: type eth netdev eth1 flavour pcivf pfnum 0 vfnum 0 pci/0000:05:00.0/2: type eth netdev eth2 flavour pcivf pfnum 0 vfnum 1 Acked-by: Jiri Pirko Signed-off-by: Parav Pandit Signed-off-by: David S.

devlink: add flash update command

2019-02-17T23:27:38+00:00

Add devlink flash update command. Advanced NICs have firmware stored in flash and often cryptographically secured. Updating that flash is handled by management firmware. Ethtool has a flash update command which served us well, however, it has two shortcomings: - it takes rtnl_lock unnecessarily - really flash update has nothing to do with networking, so using a networking device as a handle is suboptimal, which leads us to the second one: - it requires a functioning netdev - in case device enters an error state and can't spawn a netdev (e.g. communication with the device fails) there is no netdev to use as a handle for flashing. Devlink already has the ability to report the firmware versions, now with the ability to update the firmware/flash we will be able to recover devices in bad state. To enable updates of sub-components of the FW allow passing component name. This name should correspond to one of the versions reported in devlink info. v1: - replace target id with component name (Jiri).

devlink: Add health dump {get,clear} commands

2019-02-07T18:34:29+00:00

Add devlink health dump commands, in order to run an dump operation over a specific reporter. The supported operations are dump_get in order to get last saved dump (if not exist, dump now) and dump_clear to clear last saved dump. It is expected from driver's callback for diagnose command to fill it via the devlink fmsg API. Devlink will parse it and convert it to netlink nla API in order to pass it to the user.
