2021-07-27ionic: monitor fw status generationShannon Nelson
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.

2021-04-02ionic: add hw timestamp structs to interfaceShannon Nelson
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.

2021-04-02ionic: add handling of larger descriptorsShannon Nelson
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.

2021-04-02ionic: add new queue features to interfaceShannon Nelson
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 <allenbh@pensando.io> Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S.

2020-05-12ionic: support longer tx sg listsShannon Nelson
The version 1 Tx queues can use longer SG lists than the original version 0 queues, but we need to check to see if the firmware supports the v1 Tx queues. This implements the queue type query for all queue types, and uses the information to set up for using the longer Tx SG lists. Because the Tx SG list can be longer, we need to limit the max ring length to be sure we stay inside the boundaries of a DMA allocation max size, so we lower the max Tx ring size. The driver sets its highest known version in the Q_IDENTITY command, and the FW returns the highest version that it knows, bounded by the driver's version. The negotiated version number is later used in the Q_INIT commands. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>

2020-02-20ionic: fix fw_status readShannon Nelson
The fw_status field is only 8 bits, so fix the read. Also, we only want to look at the one status bit, to allow for future use of the other bits, and watch for a bad PCI read.

Pull Documentation updates from Jonathan Corbet: "Here are the main documentation changes for 5.5: - Various kerneldoc script enhancements. - More RST conversions; those are slowing down as we run out of things to convert, but we're a ways from done still. - Dan's "maintainer profile entry" work landed at last. Now we just need to get maintainers to fill in the profiles... - A reworking of the parallel build setup to work better with a variety of systems (and to not take over huge systems entirely in particular). - The MAINTAINERS file is now converted to RST during the build. Hopefully nobody ever tries to print this thing, or they will need to load a lot of paper. - A script and documentation making it easy for maintainers to add Link: tags at commit time.
