Steen Hegelund says: ==================== net: Add support for sorted VCAP rules in Sparx5 This provides support for adding Sparx5 VCAP rules in sorted order, VCAP rule counters and TC filter matching on ARP frames. It builds on top of the initial IS2 VCAP support found in these series: https://lore.kernel.org/all/20221020130904.1215072-1-steen.hegelund@microchip.com/ https://lore.kernel.org/all/20221109114116.3612477-1-steen.hegelund@microchip.com/ Functionality ============= When a new VCAP rule is added the driver will now ensure that the rule is inserted in sorted order, and when a rule is removed, the remaining rules will be moved to keep the sorted order and remove any gaps in the VCAP address space. A VCAP rule is ordered using these 3 values: - Rule size: the count of VCAP addresses used by the rule. The largest rule have highest priority - Rule User: The rules are ordered by the user enumeration - Priority: The priority provided in the flower filter. The lowest value has the highest priority. A VCAP instance may contain the counter as part of the VCAP cache area, and this counter may be one or more bits in width. This type of counter automatically increments its value when the rule is hit. Other VCAP instances have a dedicated counter area outside of the VCAP and in this case the rule must contain the counter id to be able to locate the counter value and cause the counter to be incremented. In this case there must also be a VCAP rule action that sets the counter id. The Sparx5 IS2 VCAP uses a dedicated counter area with 32bit counters. This series adds support for getting VCAP rule counters and provide these via the TC statistic interface. This only support packet counters, not byte counters. Finally the series adds support for the ARP frame dissector and configures the Sparx5 IS2 VCAP to generate the ARP keyset when ARP traffic is received. Delivery: ========= This is current plan for delivering the full VCAP feature set of Sparx5: - DebugFS support for inspecting rules - TC protocol all support - Sparx5 IS0 VCAP support - TC policer and drop action support (depends on the Sparx5 QoS support upstreamed separately) - Sparx5 ES0 VCAP support - TC flower template support - TC matchall filter support for mirroring and policing ports - TC flower filter mirror action support - Sparx5 ES2 VCAP support ==================== Signed-off-by:

This adds a sorting criteria to rule insertion and deletion. The criteria is (in the listed order): - Rule size (largest size first) - User (based on an enumerated user value) - Priority (highest priority first, aka lowest value) When a rule is deleted the other rules may need to be moved to fill the gap to use the available VCAP address space in the best possible way.

Update affinity hints on cpu hotplug events 3. Introduce transmit packet steering (XPS) NOTE: If irqbalance is running, you need to stop it from overriding our affinity hints. To do this you can do one of: - systemctl stop irqbalance - ban the ibmvnic module irqs - you must have the latest irqbalance v9.2, the banmod argument was broken before this - in /etc/sysconfig/irqbalance -> IRQBALANCE_ARGS="--banmod=ibmvnic" - systemctl restart irqbalance ==================== Signed-off-by:

Transmit Packet Steering (XPS) maps cpu numbers to transmit queues. By running the same connection on the same set of cpu's, contention for the queue and cache miss rate can be minimized. When assigning a cpu mask for a tranmit queues irq number, assign the same cpu mask as the set of cpu's that XPS should use for that queue. Signed-off-by:

When CPU's are added and removed, ibmvnic devices will reassign hint values. Introduce a new cpu hotplug state CPUHP_IBMVNIC_DEAD to signal to ibmvnic devices that the CPU has been removed and it is time to reset affinity hint assignments. On the other hand, when CPU's are being added, add a state instance to CPUHP_AP_ONLINE_DYN which will trigger a reassignment of affinity hints once the new CPU's are online. This implementation is based on the virtio_net driver. Signed-off-by:

Alex Elder says: ==================== dt-bindings: net: qcom,ipa: relax some restrictions The first patch in this series simply removes an unnecessary requirement in the IPA binding. Previously, if the modem was doing GSI firmware loading, the firmware name property was required to *not* be present. There is no harm in having the firmware name be specified, so this restriction isn't needed. The second patch restates a requirement on the "memory-region" property more accurately. These binding changes have no impact on existing code or DTS files. These aren't really bug fixes, so no need to back-port. ==================== Link: https://lore.kernel.org/r/20221110195619.1276302-1-elder@linaro.org Signed-off-by:

Either the AP or modem loads GSI firmware. If the modem-init property is present, the modem loads it. Otherwise, the AP loads it, and in that case the memory-region property must be defined. Currently this requirement is expressed as one or the other of the modem-init or the memory-region property being required. But it's harmless for the memory-region to be present if the modem is loading firmware (it'll just be ignored). Restate the requirement so that the memory-region property is required only if modem-init is not present. Signed-off-by:

Commit d8604b20 ("dt-bindings: net: qcom,ipa: add firmware-name property") added a requirement for a "firmware-name" property that is more restrictive than necessary. If the AP loads GSI firmware, the name of the firmware file to use may optionally be provided via a "firmware-name" property. If the *modem* loads GSI firmware, "firmware-name" doesn't need to be supplied--but it's harmless to do so (it will simply be ignored). Remove the unnecessary restriction, and allow "firware-name" to be supplied even if it's not needed. Signed-off-by:
