ionic: new ionic device identity level and VF start control

2022-10-28T03:34:13Z

A new ionic dev_cmd is added to the interface in ionic_if.h, with a new capabilities field in the ionic device identity to signal its availability in the FW. The identity level code is incremented to '2' to show support for this new capabilities bitfield. If the driver has indicated with the new identity level that it has the VF_CTRL command, newer FW will wait for the start command before starting the VFs after a FW update or crash recovery. This patch updates the driver to make use of the new VF start control in fw_up path to be sure that the PF has set the user attributes on the VF before the FW allows the VFs to restart.

ionic: clean up comments and whitespace

2022-02-19T04:37:14Z

Fix up some checkpatch complaints that have crept in: doubled words words, mispellled words, doubled lines. Signed-off-by: Shannon Nelson Signed-off-by: Jakub Kicinski

ionic: monitor fw status generation

2021-07-27T19:15:21Z

The top 4 bits of the fw_status in dev_info_regs is reserved for the status generation. This generation number is an arbitrary value defined when firmware starts up. If the FW is killed/crashed/stopped and then restarted, it will create a different generation number. With this mechanism, the host driver can detect that the FW has crashed and restarted, and the driver can then take steps to re-initialize its connection.

ionic: add hw timestamp structs to interface

2021-04-02T21:18:32Z

The interface for hardware timestamping includes a new FW request, device identity fields, Tx and Rx queue feature bits, a new Rx filter type, the beginnings of Rx packet classifications, and hardware timestamp registers. If the IONIC_ETH_HW_TIMESTAMP bit is shown in the ionic_lif_config features bit string, then we have support for the hw clock registers. If the IONIC_RXQ_F_HWSTAMP and IONIC_TXQ_F_HWSTAMP features are shown in the ionic_q_identity features, then the queues can support HW timestamps on packets.

ionic: add handling of larger descriptors

2021-04-02T21:18:32Z

In preparating for hardware timestamping, we need to support large Tx and Rx completion descriptors. Here we add the new queue feature ids and handling for the completion descriptor sizes. We only are adding support for the Rx 2x sized completion descriptors in the general Rx queues for now as we will be using it for PTP Rx support, and we don't have an immediate use for the large descriptors in the general Tx queues yet; it will be used in a special Tx queues added in one of the next few patches.

ionic: add new queue features to interface

2021-04-02T21:18:32Z

Add queue feature extensions to prepare for features that can be queue specific, in addition to the general queue features already defined. While we're here, change the existing feature ids from #defines to enum. Signed-off-by: Allen Hubbe Signed-off-by: Shannon Nelson Signed-off-by: David S. Miller
