Merge branch 'perf-core-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tipPull perf updates from Ingo Molnar: "Kernel side changes: - Intel Knights Landing support. (Harish Chegondi) - Intel Broadwell-EP uncore PMU support. (Kan Liang) - Core code improvements. (Peter Zijlstra.) - Event filter, LBR and PEBS fixes. (Stephane Eranian) - Enable cycles:pp on Intel Atom. (Stephane Eranian) - Add cycles:ppp support for Skylake. (Andi Kleen) - Various x86 NMI overhead optimizations. (Andi Kleen) - Intel PT enhancements. (Takao Indoh) - AMD cache events fix. (Vince Weaver) Tons of tooling changes: - Show random perf tool tips in the 'perf report' bottom line (Namhyung Kim) - perf report now defaults to --group if the perf.data file has grouped events, try it with: # perf record -e '{cycles,instructions}' -a sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 1.093 MB perf.data (1247 samples) ] # perf report # Samples: 1K of event 'anon group { cycles, instructions }' # Event count (approx.): 1955219195 # # Overhead Command Shared Object Symbol 2.86% 0.22% swapper [kernel.kallsyms] [k] intel_idle 1.05% 0.33% firefox libxul.so [.] js::SetObjectElement 1.05% 0.00% kworker/0:3 [kernel.kallsyms] [k] gen6_ring_get_seqno 0.88% 0.17% chrome chrome [.] 0x0000000000ee27ab 0.65% 0.86% firefox libxul.so [.] js::ValueToId<(js::AllowGC)1> 0.64% 0.23% JS Helper libxul.so [.] js::SplayTree::splay 0.62% 1.27% firefox libxul.so [.] js::GetIterator 0.61% 1.74% firefox libxul.so [.] js::NativeSetProperty 0.61% 0.31% firefox libxul.so [.] js::SetPropertyByDefining - Introduce the 'perf stat record/report' workflow: Generate perf.data files from 'perf stat', to tap into the scripting capabilities perf has instead of defining a 'perf stat' specific scripting support to calculate event ratios, etc. Simple example: $ perf stat record -e cycles usleep 1 Performance counter stats for 'usleep 1': 1,134,996 cycles 0.000670644 seconds time elapsed $ perf stat report Performance counter stats for '/home/acme/bin/perf stat record -e cycles usleep 1': 1,134,996 cycles 0.000670644 seconds time elapsed $ It generates PERF_RECORD_ userspace records to store the details: $ perf report -D | grep PERF_RECORD 0xf0 [0x28]: PERF_RECORD_THREAD_MAP nr: 1 thread: 27637 0x118 [0x12]: PERF_RECORD_CPU_MAP nr: 1 cpu: 65535 0x12a [0x40]: PERF_RECORD_STAT_CONFIG 0x16a [0x30]: PERF_RECORD_STAT -1 -1 0x19a [0x40]: PERF_RECORD_MMAP -1/0: [0xffffffff81000000(0x1f000000) @ 0xffffffff81000000]: x [kernel.kallsyms]_text 0x1da [0x18]: PERF_RECORD_STAT_ROUND [acme@ssdandy linux]$ An effort was made to make perf.data files generated like this to not generate cryptic messages when processed by older tools. The 'perf script' bits need rebasing, will go up later. - Make command line options always available, even when they depend on some feature being enabled, warning the user about use of such options (Wang Nan) - Support hw breakpoint events (mem:0xAddress) in the default output mode in 'perf script' (Wang Nan) - Fixes and improvements for supporting annotating ARM binaries, support ARM call and jump instructions, more work needed to have arch specific stuff separated into tools/perf/arch/*/annotate/ (Russell King) - Add initial 'perf config' command, for now just with a --list command to the contents of the configuration file in use and a basic man page describing its format, commands for doing edits and detailed documentation are being reviewed and proof-read. (Taeung Song) - Allows BPF scriptlets specify arguments to be fetched using DWARF info, using a prologue generated at compile/build time (He Kuang, Wang Nan) - Allow attaching BPF scriptlets to module symbols (Wang Nan) - Allow attaching BPF scriptlets to userspace code using uprobe (Wang Nan) - BPF programs now can specify 'perf probe' tunables via its section name, separating key=val values using semicolons (Wang Nan) Testing some of these new BPF features: Use case: get callchains when receiving SSL packets, filter then in the kernel, at arbitrary place. # cat ssl.bpf.c #define SEC(NAME) __attribute__((section(NAME), used)) struct pt_regs; SEC("func=__inet_lookup_established hnum") int func(struct pt_regs *ctx, int err, unsigned short port) { return err == 0 && port == 443; } char _license[] SEC("license") = "GPL"; int _version SEC("version") = LINUX_VERSION_CODE; # # perf record -a -g -e ssl.bpf.c ^C[ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.787 MB perf.data (3 samples) ] # perf script | head -30 swapper 0 [000] 58783.268118: perf_bpf_probe:func: (ffffffff816a0f60) hnum=0x1bb 8a0f61 __inet_lookup_established (/lib/modules/4.3.0+/build/vmlinux) 896def ip_rcv_finish (/lib/modules/4.3.0+/build/vmlinux) 8976c2 ip_rcv (/lib/modules/4.3.0+/build/vmlinux) 855eba __netif_receive_skb_core (/lib/modules/4.3.0+/build/vmlinux) 8565d8 __netif_receive_skb (/lib/modules/4.3.0+/build/vmlinux) 8572a8 process_backlog (/lib/modules/4.3.0+/build/vmlinux) 856b11 net_rx_action (/lib/modules/4.3.0+/build/vmlinux) 2a284b __do_softirq (/lib/modules/4.3.0+/build/vmlinux) 2a2ba3 irq_exit (/lib/modules/4.3.0+/build/vmlinux) 96b7a4 do_IRQ (/lib/modules/4.3.0+/build/vmlinux) 969807 ret_from_intr (/lib/modules/4.3.0+/build/vmlinux) 2dede5 cpu_startup_entry (/lib/modules/4.3.0+/build/vmlinux) 95d5bc rest_init (/lib/modules/4.3.0+/build/vmlinux) 1163ffa start_kernel ([kernel.vmlinux].init.text) 11634d7 x86_64_start_reservations ([kernel.vmlinux].init.text) 1163623 x86_64_start_kernel ([kernel.vmlinux].init.text) qemu-system-x86 9178 [003] 58785.792417: perf_bpf_probe:func: (ffffffff816a0f60) hnum=0x1bb 8a0f61 __inet_lookup_established (/lib/modules/4.3.0+/build/vmlinux) 896def ip_rcv_finish (/lib/modules/4.3.0+/build/vmlinux) 8976c2 ip_rcv (/lib/modules/4.3.0+/build/vmlinux) 855eba __netif_receive_skb_core (/lib/modules/4.3.0+/build/vmlinux) 8565d8 __netif_receive_skb (/lib/modules/4.3.0+/build/vmlinux) 856660 netif_receive_skb_internal (/lib/modules/4.3.0+/build/vmlinux) 8566ec netif_receive_skb_sk (/lib/modules/4.3.0+/build/vmlinux) 430a br_handle_frame_finish ([bridge]) 48bc br_handle_frame ([bridge]) 855f44 __netif_receive_skb_core (/lib/modules/4.3.0+/build/vmlinux) 8565d8 __netif_receive_skb (/lib/modules/4.3.0+/build/vmlinux) # - Use 'perf probe' various options to list functions, see what variables can be collected at any given point, experiment first collecting without a filter, then filter, use it together with 'perf trace', 'perf top', with or without callchains, if it explodes, please tell us!
