Merge tag 'net-next-6.15' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextPull networking updates from Jakub Kicinski: "Core & protocols: - Continue Netlink conversions to per-namespace RTNL lock (IPv4 routing, routing rules, routing next hops, ARP ioctls) - Continue extending the use of netdev instance locks. As a driver opt-in protect queue operations and (in due course) ethtool operations with the instance lock and not RTNL lock. - Support collecting TCP timestamps (data submitted, sent, acked) in BPF, allowing for transparent (to the application) and lower overhead tracking of TCP RPC performance. - Tweak existing networking Rx zero-copy infra to support zero-copy Rx via io_uring. - Optimize MPTCP performance in single subflow mode by 29%. - Enable GRO on packets which went thru XDP CPU redirect (were queued for processing on a different CPU). Improving TCP stream performance up to 2x. - Improve performance of contended connect() by 200% by searching for an available 4-tuple under RCU rather than a spin lock. Bring an additional 229% improvement by tweaking hash distribution. - Avoid unconditionally touching sk_tsflags on RX, improving performance under UDP flood by as much as 10%. - Avoid skb_clone() dance in ping_rcv() to improve performance under ping flood. - Avoid FIB lookup in netfilter if socket is available, 20% perf win. - Rework network device creation (in-kernel) API to more clearly identify network namespaces and their roles. There are up to 4 namespace roles but we used to have just 2 netns pointer arguments, interpreted differently based on context. - Use sysfs_break_active_protection() instead of trylock to avoid deadlocks between unregistering objects and sysfs access. - Add a new sysctl and sockopt for capping max retransmit timeout in TCP. - Support masking port and DSCP in routing rule matches. - Support dumping IPv4 multicast addresses with RTM_GETMULTICAST. - Support specifying at what time packet should be sent on AF_XDP sockets. - Expose TCP ULP diagnostic info (for TLS and MPTCP) to non-admin users. - Add Netlink YAML spec for WiFi (nl80211) and conntrack. - Introduce EXPORT_IPV6_MOD() and EXPORT_IPV6_MOD_GPL() for symbols which only need to be exported when IPv6 support is built as a module. - Age FDB entries based on Rx not Tx traffic in VxLAN, similar to normal bridging. - Allow users to specify source port range for GENEVE tunnels. - netconsole: allow attaching kernel release, CPU ID and task name to messages as metadata Driver API: - Continue rework / fixing of Energy Efficient Ethernet (EEE) across the SW layers. Delegate the responsibilities to phylink where possible. Improve its handling in phylib. - Support symmetric OR-XOR RSS hashing algorithm. - Support tracking and preserving IRQ affinity by NAPI itself. - Support loopback mode speed selection for interface selftests.

e1d27d29dbe5139cd6b9a5e06bfe6e18149d1bff - net: xilinx: axienet: Enable adaptive IRQ coalescing with DIM

Thu, 06 Feb 2025 21:10:36 +0100

net: xilinx: axienet: Enable adaptive IRQ coalescing with DIMThe default RX IRQ coalescing settings of one IRQ per packet can representa significant CPU load. However, increasing the coalescing unilaterallycan result in undesirable latency under low load. Adaptive IRQcoalescing with DIM offers a way to adjust the coalescing settings basedon load.This device only supports "CQE" mode [1], where each packet resets thetimer. Therefore, an interrupt is fired either when we receivecoalesce_count_rx packets or when the interface is idle forcoalesce_usec_rx. With this in mind, consider the following scenarios:Link saturated Here we want to set coalesce_count_rx to a large value, in order to coalesce more packets and reduce CPU load. coalesce_usec_rx should be set to at least the time for one packet. Otherwise the link will be "idle" and we will get an interrupt for each packet anyway.Bursts of packets Each burst should be coalesced into a single interrupt, although it may be prudent to reduce coalesce_count_rx for better latency. coalesce_usec_rx should be set to at least the time for one packet so bursts are coalesced. However, additional time beyond the packet time will just increase latency at the end of a burst.Sporadic packets Due to low load, we can set coalesce_count_rx to 1 in order to reduce latency to the minimum. coalesce_usec_rx does not matter in this case.Based on this analysis, I expected the CQE profiles to look somethinglike usec = 0, pkts = 1 // Low load usec = 16, pkts = 4 usec = 16, pkts = 16 usec = 16, pkts = 64 usec = 16, pkts = 256 // High loadWhere usec is set to 16 to be a few us greater than the 12.3 us packettime of a 1500 MTU packet at 1 GBit/s. However, the CQE profile isinstead usec = 2, pkts = 256 // Low load usec = 8, pkts = 128 usec = 16, pkts = 64 usec = 32, pkts = 64 usec = 64, pkts = 64 // High loadI found this very surprising. The number of coalesced packets*decreases* as load increases. But as load increases we have moreopportunities to coalesce packets without affecting latency as much.Additionally, the profile *increases* the usec as the load increases.But as load increases, the gaps between packets will tend to becomesmaller, making it possible to *decrease* usec for better latency at theend of a "burst".I consider the default CQE profile unsuitable for this NIC. Therefore,we use the first profile outlined in this commit instead.coalesce_usec_rx is set to 16 by default, but the user can customize it.This may be necessary if they are using jumbo frames. I think adjustingthe profile times based on the link speed/mtu would be good improvementfor generic DIM.In addition to the above profile problems, I noticed the followingadditional issues with DIM while testing:- DIM tends to "wander" when at low load, since the performance gradient is pretty flat. If you only have 10p/ms anyway then adjusting the coalescing settings will not affect throughput very much.- DIM takes a long time to adjust back to low indices when load is decreased following a period of high load. This is because it only re-evaluates its settings once every 64 interrupts. However, at low load 64 interrupts can be several seconds.Finally: performance. This patch increases receive throughput withiperf3 from 840 Mbits/sec to 938 Mbits/sec, decreases interrupts from69920/sec to 316/sec, and decreases CPU utilization (4x Cortex-A53) from43% to 9%.[1] Who names this stuff?Signed-off-by: Sean Anderson Reviewed by: Shannon Nelson Link: https://patch.msgid.link/20250206201036.1516800-5-sean.anderson@linux.devSigned-off-by: Jakub Kicinski List of files: /linux/drivers/net/ethernet/xilinx/Kconfig
