Add --off-cpu option to enable the off-cpu profiling with BPF. It'd use a bpf_output event and rename it to "offcpu-time". Samples will be synthesized at the end of the record session using data from a BPF map which contains the aggregated off-cpu time at context switches. So it needs root privilege to get the off-cpu profiling. Each sample will have a separate user stacktrace so it will skip kernel threads. The sample ip will be set from the stacktrace and other sample data will be updated accordingly. Currently it only handles some basic sample types. The sample timestamp is set to a dummy value just not to bother with other events during the sorting. So it has a very big initial value and increase it on processing each samples. Good thing is that it can be used together with regular profiling like cpu cycles. If you don't want to that, you can use a dummy event to enable off-cpu profiling only. Example output: $ sudo perf record --off-cpu perf bench sched messaging -l 1000 $ sudo perf report --stdio --call-graph=no # Total Lost Samples: 0 # # Samples: 41K of event 'cycles' # Event count (approx.): 42137343851 ... # Samples: 1K of event 'offcpu-time' # Event count (approx.): 587990831640 # # Children Self Command Shared Object Symbol # ........ ........ ............... .................. ......................... # 81.66% 0.00% sched-messaging libc-2.33.so [.] __libc_start_main 81.66% 0.00% sched-messaging perf [.] cmd_bench 81.66% 0.00% sched-messaging perf [.] main 81.66% 0.00% sched-messaging perf [.] run_builtin 81.43% 0.00% sched-messaging perf [.] bench_sched_messaging 40.86% 40.86% sched-messaging libpthread-2.33.so [.] __read 37.66% 37.66% sched-messaging libpthread-2.33.so [.] __write 2.91% 2.91% sched-messaging libc-2.33.so [.] __poll ... As you can see it spent most of off-cpu time in read and write in bench_sched_messaging(). The --call-graph=no was added just to make the output concise here. It uses perf hooks facility to control BPF program during the record session rather than adding new BPF/off-cpu specific calls. Signed-off-by:Ian Rogers <irogers@google.com> Tested-by:

Currently evsel__new_idx() sets more sample_type bits when it finds a BPF-output event. But it should honor what's recorded in the perf data file rather than blindly sets the bits. Otherwise it could lead to a parse error when it recorded with a modified sample_type. Signed-off-by:

Counts expected fields for various commands. No testing added for summary mode since it is broken. An example of the summary output is: summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle ,,,,,1.37,stalled cycles per insn This should be: summary,263831,,instructions:u,1435072,100.0,0.46,insn per cycle summary,,,,,,1.37,stalled cycles per insn The output has 7 fields when it should have 8. Additionally, the newline spacing is wrong, so it was excluded from testing until a fix is made.

Adrian Hunter authored
Uncore events require a CPU i.e. it cannot be -1. The evsel system_wide flag is intended for events that should be on every CPU, which does not make sense for uncore events because uncore events do not map one-to-one with CPUs. These 2 requirements are not exactly the same, so introduce a new flag 'requires_cpu' for the uncore case. Signed-off-by:

To support collection of system-wide events with user requested CPUs, all_cpus must be a superset of user_requested_cpus. In order to support all_cpus to be a superset of user_requested_cpus, all_cpus must be used instead of user_requested_cpus when dealing with CPUs of all events instead of CPUs of requested events.

Adrian Hunter authored
Add mmap_needed to auxtrace_mmap_params. Currently an auxtrace mmap is always attempted even if the event is not an auxtrace event. That works because, when AUX area tracing, there is always an auxtrace event first for every mmap. Prepare for that not being the case, which it won't be when sideband tracking events are allowed on all CPUs even when auxtrace is limited to selected CPUs. Signed-off-by:

The btf__load_from_kernel_by_id() only takes one arg, not two. Committer notes: I tested it just with an older libbpf, one where btf__load_from_kernel_by_id() wasn't introduced yet. A test with a newer dynamic libbpf would fail because the btf__load_from_kernel_by_id() is there, but takes just one arg.

Pull xfs updates from Dave Chinner: "This is a big update with lots of new code. The summary below them all, so I'll just touch on teh higlights. The two main new features are Large Extent Counts and Logged Attribute Replay - these are two new foundational features that we are building more complex future features on top of. For upcoming functionality, we need to be able to store hundreds of millions of xattrs per inode. The Large Extent Count feature removes the limits that prevent this scale of xattr storage, and while we were modifying the on disk extent count format we also increased the number of data extents we support per inode from 2^32 to 2^47. We also need to be able to modify xattrs as part of larger atomic transactions rather than as standalone transactions. The Logged Attribute Replay feature introduces the infrastructure that allows us to use intents to record the attribute modifications in the journal before we start them, hence allowing other atomic transactions to log attribute modification intents and then defer the actual modification to later. If we then crash, log recovery then guarantees that the attribute is replayed in the context of the atomic transaction that logged the intent. A significant chunk of the commits in this merge are for the base attribute replay functionality along with fixes, improvements and cleanups related to this new functioanlity. Allison deserves a big round of thanks for her ongoing work to get this functionality into XFS. There are also many other smaller changes and improvements, so overall this is one of the bigger XFS merge requests in some time. I will be following up next week with another smaller pull request - we already have another round of fixes and improvements to the logged attribute replay functionality just about ready to go. They'll soak and test over the next week, and I'll send a pull request for them near the end of the merge window. Summary: - support for printk message indexing. - large extent counts to provide support for up to 2^47 data extents and 2^32 attribute extents, allowing us to scale beyond 4 billion data extents to billions of xattrs per inode. - conversion of various flags fields to be consistently declared as unsigned bit fields. - improvements to realtime extent accounting and converts them to per-cpu counters to match all the other block and inode accounting. - reworks core log formatting code to reduce iterations, have a shorter, cleaner fast path and generally be easier to understand and maintain. - improvements to rmap btree searches that reduce overhead by up to 30% resulting in xfs_scrub runtime reductions of 15%. - improvements to reflink that remove the size limitations in remapping operations and greatly reduce the size of transaction reservations. - reworks the minimum log size calculations to allow us to change transaction reservations without changing the minimum supported log size. - removal of quota warning support as it has never been used on Linux. - intent whiteouts to allow us to cancel intents that are completed entirely in memory rather than having use CPU and disk bandwidth formatting and writing them into the journal when it is not necessary. This makes rmap, reflink and extent freeing slightly more efficient, but provides massive improvements for.... - Logged Attribute Replay feature support. This is a fundamental change to the way we modify attributes, laying the foundation for future integration of attribute modifications as part of other atomic transactional operations the filesystem performs. - Lots of cleanups and fixes for the logged attribute replay functionality" * tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: (124 commits) xfs: can't use kmem_zalloc() for attribute buffers xfs: detect empty attr leaf blocks in xfs_attr3_leaf_verify xfs: ATTR_REPLACE algorithm with LARP enabled needs rework xfs: use XFS_DA_OP flags in deferred attr ops xfs: remove xfs_attri_remove_iter xfs: switch attr remove to xfs_attri_set_iter xfs: introduce attr remove initial states into xfs_attr_set_iter xfs: xfs_attr_set_iter() does not need to return EAGAIN xfs: clean up final attr removal in xfs_attr_set_iter xfs: remote xattr removal in xfs_attr_set_iter() is conditional xfs: XFS_DAS_LEAF_REPLACE state only needed if !LARP xfs: split remote attr setting out from replace path xfs: consolidate leaf/node states in xfs_attr_set_iter xfs: kill XFS_DAC_LEAF_ADDNAME_INIT xfs: separate out initial attr_set states xfs: don't set quota warning values xfs: remove warning counters from struct xfs_dquot_res xfs: remove quota warning limit from struct xfs_quota_limits xfs: rework deferred attribute operation setup xfs: make xattri_leaf_bp more useful ... -

Pull networking updates from Jakub Kicinski: "Core ---- - Support TCPv6 segmentation offload with super-segments larger than 64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP). - Generalize skb freeing deferral to per-cpu lists, instead of per-socket lists. - Add a netdev statistic for packets dropped due to L2 address mismatch (rx_otherhost_dropped). - Continue work annotating skb drop reasons. - Accept alternative netdev names (ALT_IFNAME) in more netlink requests. - Add VLAN support for AF_PACKET SOCK_RAW GSO. - Allow receiving skb mark from the socket as a cmsg. - Enable memcg accounting for veth queues, sysctl tables and IPv6. BPF --- - Add libbpf support for User Statically-Defined Tracing (USDTs). - Speed up symbol resolution for kprobes multi-link attachments. - Support storing typed pointers to referenced and unreferenced objects in BPF maps. - Add support for BPF link iterator. - Introduce access to remote CPU map elements in BPF per-cpu map. - Allow middle-of-the-road settings for the kernel.unprivileged_bpf_disabled sysctl. - Implement basic types of dynamic pointers e.g. to allow for dynamically sized ringbuf reservations without extra memory copies. Protocols --------- - Retire port only listening_hash table, add a second bind table hashed by port and address. Avoid linear list walk when binding to very popular ports (e.g. 443). - Add bridge FDB bulk flush filtering support allowing user space to remove all FDB entries matching a condition. - Introduce accept_unsolicited_na sysctl for IPv6 to implement router-side changes for RFC9131. - Support for MPTCP path manager in user space. - Add MPTCP support for fallback to regular TCP for connections that have never connected additional subflows or transmitted out-of-sequence data (partial support for RFC8684 fallback). - Avoid races in MPTCP-level window tracking, stabilize and improve throughput. - Support lockless operation of GRE tunnels with seq numbers enabled. - WiFi support for host based BSS color collision detection. - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets. - Support transmission w/o flow control in CAN ISOTP (ISO 15765-2). - Support zero-copy Tx with TLS 1.2 crypto offload (sendfile). - Allow matching on the number of VLAN tags via tc-flower. - Add tracepoint for tcp_set_ca_state(). Driver API ---------- - Improve error reporting from classifier and action offload. - Add support for listing line cards in switches (devlink). - Add helpers for reporting page pool statistics with ethtool -S. - Add support for reading clock cycles when using PTP virtual clocks, instead of having the driver convert to time before reporting. This makes it possible to report time from different vclocks. - Support configuring low-latency Tx descriptor push via ethtool. - Separate Clause 22 and Clause 45 MDIO accesses more explicitly. New hardware / drivers ---------------------- - Ethernet: - Marvell's Octeon NIC PCI Endpoint support (octeon_ep) - Sunplus SP7021 SoC (sp7021_emac) - Add support for Renesas RZ/V2M (in ravb) - Add support for MediaTek mt7986 switches (in mtk_eth_soc) - Ethernet PHYs: - ADIN1100 industrial PHYs (w/ 10BASE-T1L and SQI reporting) - TI DP83TD510 PHY - Microchip LAN8742/LAN88xx PHYs - WiFi: - Driver for pureLiFi X, XL, XC devices (plfxlc) - Driver for Silicon Labs devices (wfx) - Support for WCN6750 (in ath11k) - Support Realtek 8852ce devices (in rtw89) - Mobile: - MediaTek T700 modems (Intel 5G 5000 M.2 cards) - CAN: - ctucanfd: add support for CTU CAN FD open-source IP core from Czech Technical University in Prague Drivers ------- - Delete a number of old drivers still using virt_to_bus(). - Ethernet NICs: - intel: support TSO on tunnels MPLS - broadcom: support multi-buffer XDP - nfp: support VF rate limiting - sfc: use hardware tx timestamps for more than PTP - mlx5: multi-port eswitch support - hyper-v: add support for XDP_REDIRECT - atlantic: XDP support (including multi-buffer) - macb: improve real-time perf by deferring Tx processing to NAPI - High-speed Ethernet switches: - mlxsw: implement basic line card information querying - prestera: add support for traffic policing on ingress and egress - Embedded Ethernet switches: - lan966x: add support for packet DMA (FDMA) - lan966x: add support for PTP programmable pins - ti: cpsw_new: enable bc/mc storm prevention - Qualcomm 802.11ax WiFi (ath11k): - Wake-on-WLAN support for QCA6390 and WCN6855 - device recovery (firmware restart) support - support setting Specific Absorption Rate (SAR) for WCN6855 - read country code from SMBIOS for WCN6855/QCA6390 - enable keep-alive during WoWLAN suspend - implement remain-on-channel support - MediaTek WiFi (mt76): - support Wireless Ethernet Dispatch offloading packet movement between the Ethernet switch and WiFi interfaces - non-standard VHT MCS10-11 support - mt7921 AP mode support - mt7921 IPv6 NS offload support - Ethernet PHYs: - micrel: ksz9031/ksz9131: cabletest support - lan87xx: SQI support for T1 PHYs - lan937x: add interrupt support for link detection" * tag 'net-next-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1809 commits) ptp: ocp: Add firmware header checks ptp: ocp: fix PPS source selector debugfs reporting ptp: ocp: add .init function for sma_op vector ptp: ocp: vectorize the sma accessor functions ptp: ocp: constify selectors ptp: ocp: parameterize input/output sma selectors ptp: ocp: revise firmware display ptp: ocp: add Celestica timecard PCI ids ptp: ocp: Remove #ifdefs around PCI IDs ptp: ocp: 32-bit fixups for pci start address Revert "net/smc: fix listen processing for SMC-Rv2" ath6kl: Use cc-disable-warning to disable -Wdangling-pointer selftests/bpf: Dynptr tests bpf: Add dynptr data slices bpf: Add bpf_dynptr_read and bpf_dynptr_write bpf: Dynptr support for ring buffers bpf: Add bpf_dynptr_from_mem for local dynptrs bpf: Add verifier support for dynptrs bpf: Suppress 'passing zero to PTR_ERR' warning bpf: Introduce bpf_arch_text_invalidate for bpf_prog_pack ... -
