2021-10-29bnxt_en: implement firmware live patchingEdwin Peer3-2/+174
Live patches are activated by using the 'limit no_reset' option when performing a devlink dev reload fw_activate operation. These packages must first be installed on the device in the usual way. For example, via devlink dev flash or ethtool -f. The devlink device info has also been enhanced to render stored and running live patch versions.

2021-10-29bnxt_en: Update firmware interface to 1.10.2.63Michael Chan4-8/+156
The main changes are firmware live patch support and 2 additional FEC standard counters. Add the matching FEC counters to ethtool counter array. Firmware older than 220 does not return the proper size of the extended RX counters so we need to cap it at the smaller legacy size. Otherwise the new FEC counters may show up with garbage values.

2021-10-29bnxt_en: implement dump callback for fw health reporterEdwin Peer1-0/+42
Populate the dump with firmware 'live' coredump data. This includes the information stored in NVRAM by the firmware exception handler prior to recovery. Thus, the live dump includes the desired crash context. Firmware does not support HWRM calls after RESET_NOTIFY, so there is no supported way to capture a coredump during the auto dump phase. Detect this and abort when called from devlink_health_report(). Signed-off-by: Edwin Peer <edwin.peer@broadcom.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

Add firmware event counters as well as health state severity. In the unhealthy state, recommend a remedy and inform the user as to its impact. Readability of the devlink tool's output is negatively impacted by adding these fields to the diagnosis.

The reported parameter value should not take into account the state of remote drivers. Firmware will reject remote resets as appropriate, thus it is not strictly necessary to check HOT_RESET_ALLOWED before attempting to initiate a reset.

The RTNL lock must be held between down and up to prevent interleaving state changes, especially since external state changes might release and allocate different driver resource subsets that would otherwise need to be tracked and carefully handled. If the down function fails, then devlink will not call the corresponding up function, thus the lock is released in the down error paths. v2: Don't use devlink_reload_disable() and devlink_reload_enable().

2021-10-24net: bcmgenet: Add support for 7712 16nm internal EPHYFlorian Fainelli3-5/+17
The 16nm internal EPHY that is present in 7712 is actually a 16nm Gigabit PHY which has been forced to operate in 10/100 mode. Its controls are therefore via the EXT_GPHY_CTRL registers and not via the EXT_EPHY_CTRL which are used for all GENETv5 adapters. Add a match on the 7712 compatible string to allow that differentiation to happen. On previous GENETv4 chips the EXT_CFG_IDDQ_GLOBAL_PWR bit was cleared by default, but this is not the case with this chip, so we need to make sure we clear it to power on the EPHY.

This big patch sprinkles const on local variables and function arguments which may refer to netdev->dev_addr. Commit 406f42fa0d3c ("net-next: When a bond have a massive amount of VLANs...") introduced a rbtree for faster Ethernet address look up. To maintain netdev->dev_addr in this tree we need to make all the writes to it got through appropriate helpers. Some of the changes here are not strictly required - const is sometimes cast off but pointer is not used for writing. It seems like it's still better to add the const in case the code changes later or relevant -W flags get enabled for the build. No functional changes.

In preparation for FORTIFY_SOURCE performing compile-time and run-time field bounds checking for memcpy(), memmove(), and memset(), avoid intentionally writing across neighboring fields. Use struct_group() around members queue_id, min_bw, max_bw, tsa, pri_lvl, and bw_weight so they can be referenced together. This will allow memcpy() and sizeof() to more easily reason about sizes, improve readability, and avoid future warnings about writing beyond the end of queue_id.

2021-09-22devlink: Make devlink_register to be voidLeon Romanovsky1-9/+2
devlink_register() can't fail and always returns success, but all drivers are obligated to check returned status anyway. This adds a lot of boilerplate code to handle impossible flow. Make devlink_register() void and simplify the drivers that use that API call.
