2022-02-21ravb: Use GFP_KERNEL instead of GFP_ATOMIC when possibleChristophe JAILLET
'max_rx_len' can be up to GBETH_RX_BUFF_MAX (i.e. 8192) (see 'gbeth_hw_info'). The default value of 'num_rx_ring' can be BE_RX_RING_SIZE (i.e. 1024). So this loop can allocate 8 Mo of memory. Previous memory allocations in this function already use GFP_KERNEL, so use __netdev_alloc_skb() and an explicit GFP_KERNEL instead of a implicit GFP_ATOMIC. This gives more opportunities of successful allocation.

2022-02-19dpaa2-eth: Update SINGLE_STEP register accessRadu Bulie
DPAA2 MAC supports 1588 one step timestamping. If this option is enabled then for each transmitted PTP event packet, the 1588 SINGLE_STEP register is accessed to modify the following fields: -offset of the correction field inside the PTP packet -UDP checksum update bit, in case the PTP event packet has UDP encapsulation These values can change any time, because there may be multiple PTP clients connected, that receive various 1588 frame types: - L2 only frame - UDP / Ipv4 - UDP / Ipv6 - other The current implementation uses dpni_set_single_step_cfg to update the SINLGE_STEP register. Using an MC command on the Tx datapath for each transmitted 1588 message introduces high delays, leading to low throughput and consequently to a small number of supported PTP clients. Besides these, the nanosecond correction field from the PTP packet will contain the high delay from the driver which together with the originTimestamp will render timestamp values that are unacceptable in a GM clock implementation. This patch updates the Tx datapath for 1588 messages when single step timestamp is enabled and provides direct access to SINGLE_STEP register, eliminating the overhead caused by the dpni_set_single_step_cfg MC command. MC version >= 10.32 implements this functionality. If the MC version does not have support for returning the single step register base address, the driver will use dpni_set_single_step_cfg command for updates operations. All the delay introduced by dpni_set_single_step_cfg function will be eliminated (if MC version has support for returning the base address of the single step register), improving the egress driver performance for PTP packets when single step timestamping is enabled. Before these changes the maximum throughput for 1588 messages with single step hardware timestamp enabled was around 2000pps. After the updates the throughput increased up to 32.82 Mbps / 46631.02 pps. Signed-off-by: Radu Bulie <radu-andrei.bulie@nxp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2022-02-19dpaa2-eth: Update dpni_get_single_step_cfg commandRadu Bulie
dpni_get_single_step_cfg is an MC firmware command used for retrieving the contents of SINGLE_STEP 1588 register available in a DPMAC. This patch adds a new version of this command that returns as an extra argument the physical base address of the aforementioned register. The address will be used to directly modify the contents of the SINGLE_STEP register instead of invoking the MC command dpni_set_single_step_cgf. The former approach introduced huge delays on the TX datapath when one step PTP events were transmitted. This led to low throughput and high latencies observed in the PTP correction field.

2022-02-18ionic: catch transition back to RUNNING with fw_generation 0Shannon Nelson
In some graceful updates that get initially triggered by the RESET event, especially with older firmware, the fw_generation bits don't change but the fw_status is seen to go to 0 then back to 1. However, the driver didn't perform the restart, remained waiting for fw_generation to change, and got left in limbo. This is because the clearing of idev->fw_status_ready to 0 didn't happen correctly as it was buried in the transition trigger: since the transition down was triggered not here but in the RESET event handler, the clear to 0 didn't happen, so the transition back to 1 wasn't detected. Fix this particular case by bringing the setting of idev->fw_status_ready back out to where it was before.

2022-02-17net: mscc: ocelot: annotate which traps need PTP timestampingVladimir Oltean
The ocelot switch library does not need this information, but the felix DSA driver does. As a reminder, the VSC9959 switch in LS1028A doesn't have an IRQ line for packet extraction, so to be notified that a PTP packet needs to be dequeued, it receives that packet also over Ethernet, by setting up a packet trap. The Felix driver needs to install special kinds of traps for packets in need of RX timestamps, such that the packets are replicated both over Ethernet and over the CPU port module. But the Ocelot switch library sets up more than one trap for PTP event messages; it also traps PTP general messages, MRP control messages etc. Those packets don't need PTP timestamps, so there's no reason for the Felix driver to send them to the CPU port module. By knowing which traps need PTP timestamps, the Felix driver can adjust the traps installed using ocelot_trap_add() such that only those will actually get delivered to the CPU port module.

2022-02-17net: mscc: ocelot: keep traps in a listVladimir Oltean
When using the ocelot-8021q tagging protocol, the CPU port isn't configured as an NPI port, but is a regular port. So a "trap to CPU" operation is actually a "redirect" operation. So DSA needs to set up the trapping action one way or another, depending on the tagging protocol in use. To ease DSA's work of modifying the action, keep all currently installed traps in a list, so that DSA can live-patch them when the tagging protocol changes.

We can save some space in the TCAM by using a single filter and adjusting the ingress port mask. Reuse the ocelot_trap_add() and ocelot_trap_del() functions for this purpose.

2022-02-16net/mlx5e: RX, Restrict bulk size for small Striding RQsTariq Toukan
In RQs of type multi-packet WQE (Striding RQ), each WQE is relatively large (typically 256KB) but their number is relatively small (8 in default). Re-mapping the descriptors' buffers before re-posting them is done via UMR (User-Mode Memory Registration) operations. On the one hand, posting UMR WQEs in bulks reduces communication overhead with the HW and better utilizes its processing units. On the other hand, delaying the WQE repost operations for a small RQ (say, of 4 WQEs) might drastically hit its performance, causing packet drops due to no receive buffer, for high or bursty incoming packets rate. Here we restrict the bulk size for too small RQs. Effectively, with the current constants, RQ of size 4 (minimum allowed) would have no bulking, while larger RQs will continue working with bulks of 2.

CQE compression is turned on by default on slow pci systems to help reduce the load on pci. In this case, Striding RQ was turned off as CQEs of packets that span several strides were not compressed, significantly reducing the compression effectiveness. This issue does not exist when using the newer mini_cqe format "stride_index". Hence, allow defaulting to Striding RQ in this case.

2022-02-16net: Fix an ignored error return from dm9051_get_regs()Yang Li
The return from the call to dm9051_get_regs() is int, it can be a negative error code, however this is being assigned to an unsigned int variable 'ret', so making 'ret' an int.
