2020-08-26net: Take common prefetch code structure into a functionTariq Toukan11-72/+23
Many device drivers use the same prefetch code structure to deal with small L1 cacheline size. Take this code into a function and call it from the drivers.

2020-08-24octeontx2-af: Add support for Marvell PTP coprocessorAleksey Makarov6-4/+348
Precision Timestamping block found on Octeontx2 platform is an independent coprocessor and has internal PTP hardware clock. Once configured PTP runs independently and when a packet arrives CGX hardware block gets the current timestamp from PTP block and forwards the packet to NIX by prepending timestamp to the packet. This patch adds the pci driver for PTP block. The driver gets registered by AF driver and does initial configuration and exposes a mailbox function to read and adjust PTP hardware clock. The mailbox function is called by AF consumers like netdev drivers or userspace drivers. Since PTP being a single block in platform this driver helps in accessing PTP block by any AF consumer.

Four new mbox messages ids and handler are added in order to enable or disable timestamping procedure on tx and rx side. Additionally when PTP is enabled, the packet parser must skip over 8 bytes and start analyzing packet data there. To make NPC profiles work seemlesly PTR_ADVANCE of IKPU is set so that parsing can be done as before when all data pointers are shifted by 8 bytes automatically.

2020-08-24mlxsw: spectrum_ethtool: Remove internal speeds from PTYS registerDanielle Ratson3-68/+1
The PTYS register is used to report and configure the port type and speed. Currently, internal bits in the register are used the same way other bits are used. Using the internal bits can cause bad parameter firmware errors. For example, trying to write to internal bit 25 returns: EMAD reg access failed (tid=53e2bffa00004310,reg_id=5004(ptys),type=write,status=7(bad parameter)) Remove the internal bits from the PTYS register, so that it is no longer possible to pass them to firmware.

When memory is allocated in 'typhoon_download_firmware()', GFP_ATOMIC must be used because it can be called from a .ndo_tx_timeout function. So this function can be called with the 'netif_tx_lock' acquired. The call chain is: --> typhoon_tx_timeout (.ndo_tx_timeout function) --> typhoon_start_runtime --> typhoon_download_firmware While at is, update some comments accordingly. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ @@ - PCI_DMA_NONE + DMA_NONE @@ expression e1, e2, e3; @@ - pci_alloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3; @@ - pci_zalloc_consistent(e1, e2, e3) + dma_alloc_coherent(&e1->dev, e2, e3, GFP_) @@ expression e1, e2, e3, e4; @@ - pci_free_consistent(e1, e2, e3, e4) + dma_free_coherent(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4, e5; @@ - pci_map_page(e1, e2, e3, e4, e5) + dma_map_page(&e1->dev, e2, e3, e4, e5) @@ expression e1, e2, e3, e4; @@ - pci_unmap_page(e1, e2, e3, e4) + dma_unmap_page(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_cpu(e1, e2, e3, e4) + dma_sync_single_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_single_for_device(e1, e2, e3, e4) + dma_sync_single_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_cpu(e1, e2, e3, e4) + dma_sync_sg_for_cpu(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_dma_sync_sg_for_device(e1, e2, e3, e4) + dma_sync_sg_for_device(&e1->dev, e2, e3, e4) @@ expression e1, e2; @@ - pci_dma_mapping_error(e1, e2) + dma_mapping_error(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) @@ expression e1, e2; @@ - pci_set_consistent_dma_mask(e1, e2) + dma_set_coherent_mask(&e1->dev, e2) Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Reviewed-by: David Dillow <dave@thedillows.org> Signed-off-by: David S.

2020-08-20hv_netvsc: Fix the queue_mapping in netvsc_vf_xmit()Haiyang Zhang1-1/+1
netvsc_vf_xmit() / dev_queue_xmit() will call VF NIC’s ndo_select_queue or netdev_pick_tx() again. They will use skb_get_rx_queue() to get the queue number, so the “skb->queue_mapping - 1” will be used. This may cause the last queue of VF not been used. Use skb_record_rx_queue() here, so that the skb_get_rx_queue() called later will get the correct queue number, and VF will be able to use all queues.

2020-08-20hv_netvsc: Remove "unlikely" from netvsc_select_queueHaiyang Zhang1-1/+1
When using vf_ops->ndo_select_queue, the number of queues of VF is usually bigger than the synthetic NIC. This condition may happen often. Remove "unlikely" from the comparison of ndev->real_num_tx_queues.

2020-08-20nfp: flower: add support to offload QinQ matchLouis Peens4-16/+152
When both the driver and the firmware supports QinQ the flow key structure that is send to the firmware is updated as the old method of matching on VLAN did not allow for space to add another VLAN tag. VLAN flows can now also match on the tpid field, not constrained to just 0x8100 as before.
