In ("ptp: ocp: Have FPGA fold in ns adjustment for adjtime."), the ns adjustment was written to the FPGA register, so the clock could accurately perform adjustments. However, the adjtime() call passes in a s64, while the clock adjustment registers use a s32. When trying to perform adjustments with a large value (37 sec), things fail. Examine the incoming delta, and if larger than 1 sec, use the original (coarse) adjustment method. If smaller than 1 sec, then allow the FPGA to fold in the changes over a 1 second window.

In tun, NAPI is supported and we can also use NAPI in the path of batched XDP buffs to accelerate packet processing. What is more, after we use NAPI, GRO is also supported. The iperf shows that the throughput of single stream could be improved from 4.5Gbps to 9.2Gbps. Additionally, 9.2 Gbps nearly reachs the line speed of the phy nic and there is still about 15% idle cpu core remaining on the vhost thread.

2022-03-01sfc: set affinity hints in local NUMA node onlyÍñigo Huguet1-2/+10
Affinity hints were being set to CPUs in local NUMA node first, and then in other CPUs. This was creating 2 unintended issues: 1. Channels created to be assigned each to a different physical core were assigned to hyperthreading siblings because of being in same NUMA node. Since the patch previous to this one, this did not longer happen with default rss_cpus modparam because less channels are created. 2. XDP channels could be assigned to CPUs in different NUMA nodes, decreasing performance too much (to less than half in some of my tests). This patch sets the affinity hints spreading the channels only in local NUMA node's CPUs. A fallback for the case that no CPU in local NUMA node is online has been added too. Example of CPUs being assigned in a non optimal way before this and the previous patch (note: in this system, xdp-8 to xdp-15 are created because num_possible_cpus == 64, but num_present_cpus == 32 so they're never used): $ lscpu | grep -i numa NUMA node(s): 2 NUMA node0 CPU(s): 0-7,16-23 NUMA node1 CPU(s): 8-15,24-31 $ grep -H . /proc/irq/*/0000:07:00.0*/../smp_affinity_list /proc/irq/141/0000:07:00.0-0/../smp_affinity_list:0 /proc/irq/142/0000:07:00.0-1/../smp_affinity_list:1 /proc/irq/143/0000:07:00.0-2/../smp_affinity_list:2 /proc/irq/144/0000:07:00.0-3/../smp_affinity_list:3 /proc/irq/145/0000:07:00.0-4/../smp_affinity_list:4 /proc/irq/146/0000:07:00.0-5/../smp_affinity_list:5 /proc/irq/147/0000:07:00.0-6/../smp_affinity_list:6 /proc/irq/148/0000:07:00.0-7/../smp_affinity_list:7 /proc/irq/149/0000:07:00.0-8/../smp_affinity_list:16 /proc/irq/150/0000:07:00.0-9/../smp_affinity_list:17 /proc/irq/151/0000:07:00.0-10/../smp_affinity_list:18 /proc/irq/152/0000:07:00.0-11/../smp_affinity_list:19 /proc/irq/153/0000:07:00.0-12/../smp_affinity_list:20 /proc/irq/154/0000:07:00.0-13/../smp_affinity_list:21 /proc/irq/155/0000:07:00.0-14/../smp_affinity_list:22 /proc/irq/156/0000:07:00.0-15/../smp_affinity_list:23 /proc/irq/157/0000:07:00.0-xdp-0/../smp_affinity_list:8 /proc/irq/158/0000:07:00.0-xdp-1/../smp_affinity_list:9 /proc/irq/159/0000:07:00.0-xdp-2/../smp_affinity_list:10 /proc/irq/160/0000:07:00.0-xdp-3/../smp_affinity_list:11 /proc/irq/161/0000:07:00.0-xdp-4/../smp_affinity_list:12 /proc/irq/162/0000:07:00.0-xdp-5/../smp_affinity_list:13 /proc/irq/163/0000:07:00.0-xdp-6/../smp_affinity_list:14 /proc/irq/164/0000:07:00.0-xdp-7/../smp_affinity_list:15 /proc/irq/165/0000:07:00.0-xdp-8/../smp_affinity_list:24 /proc/irq/166/0000:07:00.0-xdp-9/../smp_affinity_list:25 /proc/irq/167/0000:07:00.0-xdp-10/../smp_affinity_list:26 /proc/irq/168/0000:07:00.0-xdp-11/../smp_affinity_list:27 /proc/irq/169/0000:07:00.0-xdp-12/../smp_affinity_list:28 /proc/irq/170/0000:07:00.0-xdp-13/../smp_affinity_list:29 /proc/irq/171/0000:07:00.0-xdp-14/../smp_affinity_list:30 /proc/irq/172/0000:07:00.0-xdp-15/../smp_affinity_list:31 CPUs assignments after this and previous patch, so normal channels created only one per core in NUMA node and affinities set only to local NUMA node: $ grep -H . /proc/irq/*/0000:07:00.0*/../smp_affinity_list /proc/irq/116/0000:07:00.0-0/../smp_affinity_list:0 /proc/irq/117/0000:07:00.0-1/../smp_affinity_list:1 /proc/irq/118/0000:07:00.0-2/../smp_affinity_list:2 /proc/irq/119/0000:07:00.0-3/../smp_affinity_list:3 /proc/irq/120/0000:07:00.0-4/../smp_affinity_list:4 /proc/irq/121/0000:07:00.0-5/../smp_affinity_list:5 /proc/irq/122/0000:07:00.0-6/../smp_affinity_list:6 /proc/irq/123/0000:07:00.0-7/../smp_affinity_list:7 /proc/irq/124/0000:07:00.0-xdp-0/../smp_affinity_list:16 /proc/irq/125/0000:07:00.0-xdp-1/../smp_affinity_list:17 /proc/irq/126/0000:07:00.0-xdp-2/../smp_affinity_list:18 /proc/irq/127/0000:07:00.0-xdp-3/../smp_affinity_list:19 /proc/irq/128/0000:07:00.0-xdp-4/../smp_affinity_list:20 /proc/irq/129/0000:07:00.0-xdp-5/../smp_affinity_list:21 /proc/irq/130/0000:07:00.0-xdp-6/../smp_affinity_list:22 /proc/irq/131/0000:07:00.0-xdp-7/../smp_affinity_list:23 /proc/irq/132/0000:07:00.0-xdp-8/../smp_affinity_list:0 /proc/irq/133/0000:07:00.0-xdp-9/../smp_affinity_list:1 /proc/irq/134/0000:07:00.0-xdp-10/../smp_affinity_list:2 /proc/irq/135/0000:07:00.0-xdp-11/../smp_affinity_list:3 /proc/irq/136/0000:07:00.0-xdp-12/../smp_affinity_list:4 /proc/irq/137/0000:07:00.0-xdp-13/../smp_affinity_list:5 /proc/irq/138/0000:07:00.0-xdp-14/../smp_affinity_list:6 /proc/irq/139/0000:07:00.0-xdp-15/../smp_affinity_list:7 Signed-off-by: Íñigo Huguet <[email protected]> Acked-by: Martin Habets <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>

Currently there are functions in iavf_virtchnl.c for polling specific virtchnl receive events. These are all assigning iavf_status values to int values. Fix this and explicitly assign int values if iavf_status is not IAVF_SUCCESS. Also, refactor a small amount of duplicated code that can be reused by all of the previously mentioned functions.

2022-03-01iavf: stop leaking iavf_status as "errno" valuesMateusz Palczewski3-39/+157
Several functions in the iAVF core files take status values of the enum iavf_status and convert them into integer values. This leads to confusion as functions return both Linux errno values and status codes intermixed. Reporting status codes as if they were "errno" values can lead to confusion when reviewing error logs. Additionally, it can lead to unexpected behavior if a return value is not interpreted properly. Fix this by introducing iavf_status_to_errno, a switch that explicitly converts from the status codes into an appropriate error value. Also introduce a virtchnl_status_to_errno function for the one case where we were returning both virtchnl status codes and iavf_status codes in the same function.

2022-03-01iavf: refactor processing of VLAN V2 capability messageMateusz Palczewski2-30/+95
In order to handle the capability exchange necessary for VIRTCHNL_VF_OFFLOAD_VLAN_V2, the driver must send a VIRTCHNL_OP_GET_OFFLOAD_VLAN_V2_CAPS message. This must occur prior to __IAVF_CONFIG_ADAPTER, and the driver must wait for the response from the PF. To handle this, the __IAVF_INIT_GET_OFFLOAD_VLAN_V2_CAPS state was introduced. This state is intended to process the response from the VLAN V2 caps message. This works ok, but is difficult to extend to adding more extended capability exchange. Existing (and future) AVF features are relying more and more on these sort of extended ops for processing additional capabilities. Just like VLAN V2, this exchange must happen prior to __IAVF_CONFIG_ADPATER. Since we only send one outstanding AQ message at a time during init, it is not clear where to place this state. Adding more capability specific states becomes a mess. Instead of having the "previous" state send a message and then transition into a capability-specific state, introduce __IAVF_EXTENDED_CAPS state. This state will use a list of extended_caps that determines what messages to send and receive. As long as there are extended_caps bits still set, the driver will remain in this state performing one send or one receive per state machine loop. Refactor the VLAN V2 negotiation to use this new state, and remove the capability-specific state. This makes it significantly easier to add a new similar capability exchange going forward. Extended capabilities are processed by having an associated SEND and RECV extended capability bit. During __IAVF_EXTENDED_CAPS, the driver checks these bits in order by feature, first the send bit for a feature, then the recv bit for a feature. Each send flag will call a function that sends the necessary response, while each receive flag will wait for the response from the PF. If a given feature can't be negotiated with the PF, the associated flags will be cleared in order to skip processing of that feature.

2022-03-01vxlan: vni filtering support on collect metadata deviceRoopa Prabhu5-30/+1121
This patch adds vnifiltering support to collect metadata device. Motivation: You can only use a single vxlan collect metadata device for a given vxlan udp port in the system today. The vxlan collect metadata device terminates all received vxlan packets. As shown in the below diagram, there are use-cases where you need to support multiple such vxlan devices in independent bridge domains. Each vxlan device must terminate the vni's it is configured for. Example usecase: In a service provider network a service provider typically supports multiple bridge domains with overlapping vlans. One bridge domain per customer. Vlans in each bridge domain are mapped to globally unique vxlan ranges assigned to each customer. vnifiltering support in collect metadata devices terminates only configured vnis. This is similar to vlan filtering in bridge driver. The vni filtering capability is provided by a new flag on collect metadata device. In the below pic: - customer1 is mapped to br1 bridge domain - customer2 is mapped to br2 bridge domain - customer1 vlan 10-11 is mapped to vni 1001-1002 - customer2 vlan 10-11 is mapped to vni 2001-2002 - br1 and br2 are vlan filtering bridges - vxlan1 and vxlan2 are collect metadata devices with vnifiltering enabled ┌──────────────────────────────────────────────────────────────────┐ │ switch │ │ │ │ ┌───────────┐ ┌───────────┐ │ │ │ │ │ │ │ │ │ br1 │ │ br2 │ │ │ └┬─────────┬┘ └──┬───────┬┘ │ │ vlans│ │ vlans │ │ │ │ 10,11│ │ 10,11│ │ │ │ │ vlanvnimap: │ vlanvnimap: │ │ │ 10-1001,11-1002 │ 10-2001,11-2002 │ │ │ │ │ │ │ │ ┌──────┴┐ ┌──┴─────────┐ ┌───┴────┐ │ │ │ │ swp1 │ │vxlan1 │ │ swp2 │ ┌┴─────────────┐ │ │ │ │ │ vnifilter:│ │ │ │vxlan2 │ │ │ └───┬───┘ │ 1001,1002│ └───┬────┘ │ vnifilter: │ │ │ │ └────────────┘ │ │ 2001,2002 │ │ │ │ │ └──────────────┘ │ │ │ │ │ └───────┼──────────────────────────────────┼───────────────────────┘ │ │ │ │ ┌─────┴───────┐ │ │ customer1 │ ┌─────┴──────┐ │ host/VM │ │customer2 │ └─────────────┘ │ host/VM │ └────────────┘ With this implementation, vxlan dst metadata device can be associated with range of vnis. struct vxlan_vni_node is introduced to represent a configured vni. We start with vni and its associated remote_ip in this structure. This structure can be extended to bring in other per vni attributes if there are usecases for it. A vni inherits an attribute from the base vxlan device if there is no per vni attributes defined. struct vxlan_dev gets a new rhashtable for vnis called vxlan_vni_group. vxlan_vnifilter.c implements the necessary netlink api, notifications and helper functions to process and manage lifecycle of vxlan_vni_node. This patch also adds new helper functions in vxlan_multicast.c to handle per vni remote_ip multicast groups which are part of vxlan_vni_group.
