Ido Schimmel says: ==================== selftests: mlxsw: Various updates This patchset contains various updates to mlxsw selftests. Patch #1 replaces open-coded compatibility checks with dedicated helpers. These helpers are used to skip tests when run on incompatible machines. Patch #2 avoids spurious failures in some tests by using permanent neighbours instead of reachable ones. Patch #3 reduces the run time of a test by not iterating over all the available trap policers. ==================== Signed-off-by: -

Instead of iterating over all the available trap policers, only perform the tests with three policers: The first, the last and the one in the middle of the range. On a Spectrum-3 system, this reduces the run time from almost an hour to a few minutes. Signed-off-by:

The nexthop objects tests configure dummy reachable neighbours so that the nexthops will have a MAC address and be programmed to the device. Since these are dummy reachable neighbours, they can be transitioned by the kernel to a failed state if they are around for too long. This can happen, for example, if the "TIMEOUT" variable is configured with a too high value. Make the tests more robust by configuring the neighbours as permanent, so that the tests do not depend on the configured timeout value. Signed-off-by:

A number of mlxsw-specific selftests currently detect whether they are run on a compatible machine, and bail out silently when not. These tests are however done in a somewhat impenetrable manner by directly comparing PCI IDs against a blacklist or a whitelist, and bailing out silently if the machine is not compatible. Instead, add a helper, mlxsw_only_on_spectrum(), which allows specifying the supported machines in a human-readable manner. If the current machine is incompatible, the helper emits a SKIP message and returns an error code, based on which the caller can gracefully bail out in a suitable way. This allows a more readable conditions such as: mlxsw_only_on_spectrum 2+ || return Convert all existing open-coded guards to the new helper. Also add two new guards to do_mark_test() and do_drop_test(), which are supported only on Spectrum-2+, but the corresponding check was not there. Signed-off-by:

Currently, the ethtool advertised link modes of FIBRE port is cleared to zero when autoneg is off, so user can not get the advertised link modes info directly from "ethtool <dev>" command.

The mac statistics add pause/pfc durations in device version V3, we can get total active cycle of pause/pfc from these durations. As driver gets register number from firmware to calculate desc number to query mac statistics, it needs to set mac statistics extended enable bit in firmware command 0x701A to tell firmware that driver supports extended mac statistics, otherwise firmware only returns register number of version V1. As pause/pfc durations are not supported by hardware of old version, they should not been shown in command "ethtool -S ethX" in this case, so add checking max register number of each mac statistic in their version. If the max register number of one mac statistic is greater than register number got from firmware, it means hardware does not support this mac statistic, so ignore this statistic when get string and data of mac statistic.

Currently, driver queries number of mac statistics before querying mac statistics. As the number of mac statistics is a fixed value in firmware, it is redundant to query this number everytime before querying mac statistics, it can just be queried once in initialization process and saved in device specifications. Signed-off-by:

Guangbin Huang authored
After querying mac statistics from firmware, driver copies data from descriptors to struct mac_stats of hdev, and the number of copied data is just according to the register number queried from firmware. There is a problem that if the register number queried from firmware is larger than data number of struct mac_stats, it will cause a copy overflow. So if the firmware adds more mac statistics in later version, it is not compatible with driver of old version. To fix this problem, the number of copied data needs to be used the minimum value between the register number queried from firmware and data number of struct mac_stats. The first descriptor has three data and there is one reserved, to optimize the copy process, add this reserverd data to struct mac_stats. Signed-off-by:

Since user may need to check the current configuration of the interrupt coalesce, so add debugfs support for query this info. Create a single file "coalesce_info" for it, and query it by "cat coalesce_info", return the result to userspace. For device whose version is above V3(include V3), the GL's register contains usecs and 1us unit configuration. When get the usecs configuration from this register, it will include the confusing unit configuration, so add a GL mask to get the correct value, and add a QL mask for the frames configuration as well. The display style is below: $ cat coalesce_info tx interrupt coalesce info: VEC_ID ALGO_STATE PROFILE_ID CQE_MODE TUNE_STATE STEPS_LEFT... 0 IN_PROG 4 EQE ON_TOP 0... 1 START 3 EQE LEFT 1... rx interrupt coalesce info: VEC_ID ALGO_STATE PROFILE_ID CQE_MODE TUNE_STATE STEPS_LEFT... 0 IN_PROG 3 EQE LEFT 1... 1 IN_PROG 0 EQE ON_TOP 0...

The only actual user of qdio.no_input_queues is qeth_qdio_establish(), and there we already have full awareness of the current Input Queue configuration (1 RX queue, plus potentially 1 TX Completion queue). So avoid this state tracking, and the ambiguity it brings with it. Signed-off-by:

For none of the users we are under risk of running in HW IRQ context or or with IRQs disabled. Thus we always end up in consume_skb(). But the two occurences in the RX path should really report the dropped packet to dropmon, so have them use kfree_skb() instead. That's also consistent with what napi_free_frags() does internally.

qdio.ko no longer needs to care about how the QAOBs are allocated, from its perspective they are merely another parameter to do_QDIO(). So for a start, shift the cache into the only qdio driver that uses QAOBs (ie. qeth). Here there's further opportunity to optimize its usage in the future - eg. make it per-{device, TX queue}, or only compile it when the driver is built with CQ/QAOB support.

With commit 18787eee ("qeth: use ndo_siocdevprivate") this callback is now actually used to handle transport mode-specific _private_ ioctls. We only have such ioctls for L3 devices. So wire up a L3-specific .ndo_siocdevprivate() callback that handles those ioctls, and defers to the core qeth_siocdevprivate() for all other private ioctls. This takes the discipline one step closer to its original purpose of providing an internal extension for the qeth_core_ccwgroup_driver. Signed-off-by:

Vladimir Oltean says: ==================== Drop rtnl_lock from DSA .port_fdb_{add,del} As mentioned in the RFC posted 2 months ago: https://patchwork.kernel.org/project/netdevbpf/cover/20210824114049.3814660-1-vladimir.oltean@nxp.com/ DSA is transitioning to a driver API where the rtnl_lock is not held when calling ds->ops->port_fdb_add() and ds->ops->port_fdb_del(). Drivers cannot take that lock privately from those callbacks either. This change is required so that DSA can wait for switchdev FDB work items to finish before leaving the bridge. That change will be made in a future patch series. A small selftest is provided with the patch set in the hope that concurrency issues uncovered by this series, but not spotted by me by code inspection, will be caught. A status of the existing drivers: - mv88e6xxx_port_fdb_add() and mv88e6xxx_port_fdb_del() take mv88e6xxx_reg_lock() so they should be safe. - qca8k_fdb_add() and qca8k_fdb_del() take mutex_lock(&priv->reg_mutex) so they should be safe. - hellcreek_fdb_add() and hellcreek_fdb_add() take mutex_lock(&hellcreek->reg_lock) so they should be safe. - ksz9477_port_fdb_add() and ksz9477_port_fdb_del() take mutex_lock(&dev->alu_mutex) so they should be safe. - b53_fdb_add() and b53_fdb_del() did not have locking, so I've added a scheme based on my own judgement there (not tested). - felix_fdb_add() and felix_fdb_del() did not have locking, I've added and tested a locking scheme there. - mt7530_port_fdb_add() and mt7530_port_fdb_del() take mutex_lock(&priv->reg_mutex), so they should be safe. - gswip_port_fdb() did not have locking, so I've added a non-expert locking scheme based on my own judgement (not tested). - lan9303_alr_add_port() and lan9303_alr_del_port() take mutex_lock(&chip->alr_mutex) so they should be safe. - sja1105_fdb_add() and sja1105_fdb_del() did not have locking, I've added and tested a locking scheme. Changes in v3: Unlock arl_mutex only once in b53_fdb_dump(). Changes in v4: - Use __must_hold in ocelot and b53 - Add missing mutex_init in lantiq_gswip - Clean up the selftest a bit. Changes in v5: - Replace __must_hold with a comment. - Add a new patch (01/10). ==================== Signed-off-by:
