RPS\ndistributes the load of received packet processing across multiple CPUs.\n\nProblem statement: Protocol processing done in the NAPI context for received\npackets is serialized per device queue and becomes a bottleneck under high\npacket load. This substantially limits pps that can be achieved on a single\nqueue NIC and provides no scaling with multiple cores.\n\nThis solution queues packets early on in the receive path on the backlog queues\nof other CPUs. This allows protocol processing (e.g. IP and TCP) to be\nperformed on packets in parallel. For each device (or each receive queue in\na multi-queue device) a mask of CPUs is set to indicate the CPUs that can\nprocess packets. A CPU is selected on a per packet basis by hashing contents\nof the packet header (e.g. the TCP or UDP 4-tuple) and using the result to index\ninto the CPU mask. The IPI mechanism is used to raise networking receive\nsoftirqs between CPUs. This effectively emulates in software what a multi-queue\nNIC can provide, but is generic requiring no device support.\n\nMany devices now provide a hash over the 4-tuple on a per packet basis\n(e.g. the Toeplitz hash). This patch allow drivers to set the HW reported hash\nin an skb field, and that value in turn is used to index into the RPS maps.\nUsing the HW generated hash can avoid cache misses on the packet when\nsteering it to a remote CPU.\n\nThe CPU mask is set on a per device and per queue basis in the sysfs variable\n/sys/class/net/\u003cdevice\u003e/queues/rx-\u003cn\u003e/rps_cpus. This is a set of canonical\nbit maps for receive queues in the device (numbered by \u003cn\u003e). If a device\ndoes not support multi-queue, a single variable is used for the device (rx-0).\n\nGenerally, we have found this technique increases pps capabilities of a single\nqueue device with good CPU utilization. Optimal settings for the CPU mask\nseem to depend on architectures and cache hierarcy. Below are some results\nrunning 500 instances of netperf TCP_RR test with 1 byte req. and resp.\nResults show cumulative transaction rate and system CPU utilization.\n\ne1000e on 8 core Intel\n Without RPS: 108K tps at 33% CPU\n With RPS: 311K tps at 64% CPU\n\nforcedeth on 16 core AMD\n Without RPS: 156K tps at 15% CPU\n With RPS: 404K tps at 49% CPU\n\nbnx2x on 16 core AMD\n Without RPS 567K tps at 61% CPU (4 HW RX queues)\n Without RPS 738K tps at 96% CPU (8 HW RX queues)\n With RPS: 854K tps at 76% CPU (4 HW RX queues)\n\nCaveats:\n- The benefits of this patch are dependent on architecture and cache hierarchy.\nTuning the masks to get best performance is probably necessary.\n- This patch adds overhead in the path for processing a single packet. In\na lightly loaded server this overhead may eliminate the advantages of\nincreased parallelism, and possibly cause some relative performance degradation.\nWe have found that masks that are cache aware (share same caches with\nthe interrupting CPU) mitigate much of this.\n- The RPS masks can be changed dynamically, however whenever the mask is changed\nthis introduces the possibility of generating out of order packets. It\u0027s\nprobably best not change the masks too frequently.\n\nSigned-off-by: Tom Herbert \u003ctherbert@google.com\u003e\n\n include/linux/netdevice.h | 32 ++++-\n include/linux/skbuff.h | 3 +\n net/core/dev.c | 335 +++++++++++++++++++++++++++++++++++++--------\n net/core/net-sysfs.c | 225 ++++++++++++++++++++++++++++++-\n net/core/skbuff.c | 2 +\n 5 files changed, 538 insertions(+), 59 deletions(-)\nSigned-off-by: Eric Dumazet \u003ceric.dumazet@gmail.com\u003e\nSigned-off-by: David S.

AFter I completed that work it was\nrequested that this feature be generalized so that any datagram oriented socket\ncould make use of this option.

It also augments the AF_PACKET\nprotocol to take advantage of this new feature (as it previously did not touch\nsk-\u003esk_drops, which this patch uses to record the overflow count). Tested\nsuccessfully by me.\n\nNotes:\n\n1) Unlike my previous patch, this patch simply records the sk_drops value, which\nis not a number of drops between packets, but rather a total number of drops.\nDeltas must be computed in user space.\n\n2) While this patch currently works with datagram oriented protocols, it will\nalso be accepted by non-datagram oriented protocols. I\u0027m not sure if thats\nagreeable to everyone, but my argument in favor of doing so is that, for those\nprotocols which aren\u0027t applicable to this option, sk_drops will always be zero,\nand reporting no drops on a receive queue that isn\u0027t used for those\nnon-participating protocols seems reasonable to me.

Try to return back to pre-split\nstate already while more and more SACK info gets discovered by\ncombining newly discovered SACK areas with the previous skb if\nthat\u0027s SACKed as well.\n\nThis approach has a number of benefits:\n\n1) The processing overhead is spread more equally over the RTT\n2) Write queue has less skbs to process (affect everything\n which has to walk in the queue past the sacked areas)\n3) Write queue is consistent whole the time, so no other parts\n of TCP has to be aware of this (this was not the case with\n some other approach that was, well, quite intrusive all\n around).\n4) Clean_rtx_queue can release most of the pages using single\n put_page instead of previous PAGE_SIZE/mss+1 calls\n\nIn case a hole is fully filled by the new SACK block, we attempt\nto combine the next skb too which allows construction of skbs\nthat are even larger than what tso split them to and it handles\nhole per on every nth patterns that often occur during slow start\novershoot pretty nicely. Though this to be really useful also\na retransmission would have to get lost since cumulative ACKs\nadvance one hole at a time in the most typical case.\n\nTODO: handle upwards only merging. That should be rather easy\nwhen segment is fully sacked but I\u0027m leaving that as future\nwork item (it won\u0027t make very large difference anyway since\nthis current approach already covers quite a lot of normal\ncases).\n\nI was earlier thinking of some sophisticated way of tracking\ntimestamps of the first and the last segment but later on\nrealized that it won\u0027t be that necessary at all to store the\ntimestamp of the last segment. The cases that can occur are\nbasically either:\n 1) ambiguous \u003d\u003e no sensible measurement can be taken anyway\n 2) non-ambiguous is due to reordering \u003d\u003e having the timestamp\n of the last segment there is just skewing things more off\n than does some good since the ack got triggered by one of\n the holes (besides some substle issues that would make\n determining right hole/skb even harder problem). Anyway,\n it has nothing to do with this change then.\n\nI choose to route some abnormal looking cases with goto noop,\nsome could be handled differently (eg., by stopping the\nwalking at that skb but again). In general, they either\nshouldn\u0027t happen at all or are rare enough to make no difference\nin practice.\n\nIn theory this change (as whole) could cause some macroscale\nregression (global) because of cache misses that are taken over\nthe round-trip time but it gets very likely better because of much\nless (local) cache misses per other write queue walkers and the\nbig recovery clearing cumulative ack.\n\nWorth to note that these benefits would be very easy to get also\nwithout TSO/GSO being on as long as the data is in pages so that\nwe can merge them. Currently I won\u0027t let that happen because\nDSACK splitting at fragment that would mess up pcounts due to\nsk_can_gso in tcp_set_skb_tso_segs.
