2018-11-17cxgb4: Remove SGE_HOST_PAGE_SIZE dependency on page sizeArjun Vynipadath
The SGE Host Page Size has nothing to do with the actual Host Page Size. It's the SGE's BAR2 Doorbell/GTS Page Size for interpreting the SGE Ingress/Egress Queue per Page values. Firmware reads all of these things and makes all the subsequent changes necessary. The Host Driver uses the SGE Host Page Size in order to properly calculate BAR2 Offsets.

2018-11-16dpaa2-eth: Don't use multiple queues per channelIoana Ciocoi Radulescu
The DPNI object on which we build a network interface has a certain number of {Rx, Tx, Tx confirmation} frame queues as resources. The default hardware setup offers one queue of each type, as well as one DPCON channel, for each core available in the system. There are however cases where the number of queues is greater than the number of cores or channels. Until now, we configured and used all the frame queues associated with a DPNI, even if it meant assigning multiple queues of one type to the same channel. Update the driver to only use a number of queues equal to the number of channels, ensuring each channel will contain exactly one Rx and one Tx confirmation queue. >From the user viewpoint, this change is completely transparent. Performance wise there is no impact in most scenarios. In case the number of queues is larger than and not a multiple of the number of channels, Rx hash distribution offers now better load balancing between cores, which can have a positive impact on overall system performance.

Lance Roy updates i40e to use lockdep_assert_held() instead of spin_is_locked(), since it is better suited to check locking requirements. Jan improves the code readability in XDP by adding the use of a local variable. Provides protection on methods that create/modify/destroy VF's via locking mechanism to prevent unstable behaviour and potential kernel panics. Krzysztof adds a hardware capability flag to indicate whether firmware supports stopping the LLDP agent. Patryk replaces the use of strncpy() with strlcpy() to ensure the buffer is NULL terminated. Mitch fixes the issue of trying to start nway on devices that do not support auto-negotiation, by checking the autoneg state before attempting to restart nway. Alice updates virtchnl to keep the checks all together for ease of readability and consistency. Also fixed a "off by one" error in the number of traffic classes being calculated. Richard fixed VF port VLANs, where the priority bits were incorrectly set because the incorrect shift and mask bits were being used. Alan adds a bit to set and check if a timeout recovery is already pending to prevent overlapping transmit timeout recovery. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Brett cleans up debug print messages by removing useless or duplicate messages, and make sure we assign the hardware head pointer to head instead of the software head pointer. Resolved an issue when disabling SRIOV we were trying to stop queues multiple times, so make sure we disable SRIOV before stopping transmit and receive queues for VF. Tony fixes a potential NULL pointer dereference during a VF reset. Anirudh resolves an issue where we were releasing the VSI before removing the VSI scheduler node, which was resulting in an error "Failed to set LAN Tx queue context, error: -1". Also fixed the guaranteed number of VSIs available and used by discovering the device capabilities to determine the 'guar_num_vsi' per function, rather than always using the theoretical max number of VSIs every time. Dave avoids a deadlock by nesting RTNL locking, so added a boolean to determine if the RTNL lock is already held. Lev fixes bad mask values which would break compilation. Piotr increases the receive queue disable timeout since it can take additional time to finish all pending queue requests. Usha resolves an issue of VLAN priority tagged traffic not appearing on all traffic classes, which was causing ETS bandwidth shaping to not work as expected.

2018-11-14i40e: prevent overlapping tx_timeout recoverAlan Brady
If a TX hang occurs, we attempt to recover by incrementally resetting. If we're starved for CPU time, it's possible the reset doesn't actually complete (or even fire) before another tx_timeout fires causing us to fly through the different resets without actually doing them. This adds a bit to set and check if a timeout recovery is already pending and, if so, bail out of tx_timeout. The bit will get cleared at the end of i40e_rebuild when reset is complete.

This isn't the fault of the poor VF driver - the PF driver itself is making the request. To fix this, skip the privilege check if the request is to disable all promiscuous activity.

Each slave has it's own receive timestamp filter. But cpts rx/tx timestamp enable flags are used to allow ts retrieve only for one user. This limitation causes data path redundancy and setting overlap if cpsw module is in dual-mac mode for instance. If rx ts is enabled only for one port - the second interface must expect every incoming packet to be PTP packet w/o absolutely any reason, and if it's PTP - do unneeded stuff, as rx filter for second port is not set and cpts fifo is not supposed to contain appropriate ts event. That's not correct. So, to fix control overlap and avoid redundant CPU cycles, the patch splits rx/tx ts enable flags between network devices. After the patch, PTP timestamping still should be used for only one port (or PTP id counter has to be different for both ports as cpts IP is common).

The overflow event is running with 1 jiffy in case if txq is not empty, but it can be emptied completely only if next tx event consumes skb or deletes staled skb from the txq. In case of staled skb, that can happen for some unpredictable reason (the ts event was lost or timed out), the overflow event can be generated quite long time consuming CPU w/o reason before next tx event happens. To avoid it, purge txq before increasing overflow event rate. Signed-off-by: Ivan Khoronzhuk <ivan.khoronzhuk@linaro.org> Signed-off-by: David S. Miller <davem@davemloft.net>
