perf data: Add perf data to CTF conversion support Adding 'perf data convert' to convert perf data file into different format. This patch adds support for CTF format conversion. To convert perf.data into CTF run: $ perf data convert --to-ctf=./ctf-data/ [ perf data convert: Converted 'perf.data' into CTF data './ctf-data/' ] [ perf data convert: Converted and wrote 11.268 MB (100230 samples) ] The command will create CTF metadata out of perf.data file (or one specified via -i option) and then convert all sample events into single CTF stream. Each sample_type bit is translated into separated CTF event field apart from following exceptions: PERF_SAMPLE_RAW - added in next patch PERF_SAMPLE_READ - TODO PERF_SAMPLE_CALLCHAIN - TODO PERF_SAMPLE_BRANCH_STACK - TODO PERF_SAMPLE_REGS_USER - TODO PERF_SAMPLE_STACK_USER - TODO $ perf --debug=data-convert=2 data convert ... The converted CTF data could be analyzed by CTF tools, like babletrace or tracecompass [1]. $ babeltrace ./ctf-data/ [03:19:13.962125533] (+?.?????????) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 1 } [03:19:13.962130001] (+0.000004468) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 1 } [03:19:13.962131936] (+0.000001935) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 8 } [03:19:13.962133732] (+0.000001796) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 114 } [03:19:13.962135557] (+0.000001825) cycles: { }, { ip = 0xFFFFFFFF8105443A, tid = 20714, pid = 20714, period = 2087 } [03:19:13.962137627] (+0.000002070) cycles: { }, { ip = 0xFFFFFFFF81361938, tid = 20714, pid = 20714, period = 37582 } [03:19:13.962161091] (+0.000023464) cycles: { }, { ip = 0xFFFFFFFF8124218F, tid = 20714, pid = 20714, period = 600246 } [03:19:13.962517569] (+0.000356478) cycles: { }, { ip = 0xFFFFFFFF811A75DB, tid = 20714, pid = 20714, period = 1325731 } [03:19:13.969518008] (+0.007000439) cycles: { }, { ip = 0x34080917B2, tid = 20714, pid = 20714, period = 1144298 } The following members to the ctf-environment were decided to be added to distinguish and specify perf CTF data: - domain It says "kernel" because it contains a kernel trace (not to be confused with a user space like lttng-ust does) - tracer_name It says perf. This can be used to distinguish between lttng and perf CTF based trace. - version The kernel version from stream.

perf tools: Handle PERF_RECORD_BPF_EVENT This patch adds basic handling of PERF_RECORD_BPF_EVENT. Tracking of PERF_RECORD_BPF_EVENT is OFF by default. Option --bpf-event is added to turn it on. Committer notes: Add dummy machine__process_bpf_event() variant that returns zero for systems without HAVE_LIBBPF_SUPPORT, such as Alpine Linux, unbreaking the build in such systems. Remove the needless include <machine.h> from bpf->event.h, provide just forward declarations for the structs and unions in the parameters, to reduce compilation time and needless rebuilds when machine.h gets changed. Committer testing: When running with: # perf record --bpf-event On an older kernel where PERF_RECORD_BPF_EVENT and PERF_RECORD_KSYMBOL is not present, we fallback to removing those two bits from perf_event_attr, making the tool to continue to work on older kernels: perf_event_attr: size 112 { sample_period, sample_freq } 4000 sample_type IP|TID|TIME|PERIOD read_format ID disabled 1 inherit 1 mmap 1 comm 1 freq 1 enable_on_exec 1 task 1 precise_ip 3 sample_id_all 1 exclude_guest 1 mmap2 1 comm_exec 1 ksymbol 1 bpf_event 1 ------------------------------------------------------------ sys_perf_event_open: pid 5779 cpu 0 group_fd -1 flags 0x8 sys_perf_event_open failed, error -22 switching off bpf_event ------------------------------------------------------------ perf_event_attr: size 112 { sample_period, sample_freq } 4000 sample_type IP|TID|TIME|PERIOD read_format ID disabled 1 inherit 1 mmap 1 comm 1 freq 1 enable_on_exec 1 task 1 precise_ip 3 sample_id_all 1 exclude_guest 1 mmap2 1 comm_exec 1 ksymbol 1 ------------------------------------------------------------ sys_perf_event_open: pid 5779 cpu 0 group_fd -1 flags 0x8 sys_perf_event_open failed, error -22 switching off ksymbol ------------------------------------------------------------ perf_event_attr: size 112 { sample_period, sample_freq } 4000 sample_type IP|TID|TIME|PERIOD read_format ID disabled 1 inherit 1 mmap 1 comm 1 freq 1 enable_on_exec 1 task 1 precise_ip 3 sample_id_all 1 exclude_guest 1 mmap2 1 comm_exec 1 ------------------------------------------------------------ And then proceeds to work without those two features. As passing --bpf-event is an explicit action performed by the user, perhaps we should emit a warning telling that the kernel has no such feature, but this can be done on top of this patch. Now with a kernel that supports these events, start the 'record --bpf-event -a' and then run 'perf trace sleep 10000' that will use the BPF augmented_raw_syscalls.o prebuilt (for another kernel version even) and thus should generate PERF_RECORD_BPF_EVENT events: [root@quaco ~]# perf record -e dummy -a --bpf-event ^C[ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.713 MB perf.data ] [root@quaco ~]# bpftool prog 13: cgroup_skb tag 7be49e3934a125ba gpl loaded_at 2019-01-19T09:09:43-0300 uid 0 xlated 296B jited 229B memlock 4096B map_ids 13,14 14: cgroup_skb tag 2a142ef67aaad174 gpl loaded_at 2019-01-19T09:09:43-0300 uid 0 xlated 296B jited 229B memlock 4096B map_ids 13,14 15: cgroup_skb tag 7be49e3934a125ba gpl loaded_at 2019-01-19T09:09:43-0300 uid 0 xlated 296B jited 229B memlock 4096B map_ids 15,16 16: cgroup_skb tag 2a142ef67aaad174 gpl loaded_at 2019-01-19T09:09:43-0300 uid 0 xlated 296B jited 229B memlock 4096B map_ids 15,16 17: cgroup_skb tag 7be49e3934a125ba gpl loaded_at 2019-01-19T09:09:44-0300 uid 0 xlated 296B jited 229B memlock 4096B map_ids 17,18 18: cgroup_skb tag 2a142ef67aaad174 gpl loaded_at 2019-01-19T09:09:44-0300 uid 0 xlated 296B jited 229B memlock 4096B map_ids 17,18 21: cgroup_skb tag 7be49e3934a125ba gpl loaded_at 2019-01-19T09:09:45-0300 uid 0 xlated 296B jited 229B memlock 4096B map_ids 21,22 22: cgroup_skb tag 2a142ef67aaad174 gpl loaded_at 2019-01-19T09:09:45-0300 uid 0 xlated 296B jited 229B memlock 4096B map_ids 21,22 31: tracepoint name sys_enter tag 12504ba9402f952f gpl loaded_at 2019-01-19T09:19:56-0300 uid 0 xlated 512B jited 374B memlock 4096B map_ids 30,29,28 32: tracepoint name sys_exit tag c1bd85c092d6e4aa gpl loaded_at 2019-01-19T09:19:56-0300 uid 0 xlated 256B jited 191B memlock 4096B map_ids 30,29 # perf report -D | grep PERF_RECORD_BPF_EVENT | nl 1 0 55834574849 0x4fc8 [0x18]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 13 2 0 60129542145 0x5118 [0x18]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 14 3 0 64424509441 0x5268 [0x18]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 15 4 0 68719476737 0x53b8 [0x18]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 16 5 0 73014444033 0x5508 [0x18]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 17 6 0 77309411329 0x5658 [0x18]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 18 7 0 90194313217 0x57a8 [0x18]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 21 8 0 94489280513 0x58f8 [0x18]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 22 9 7 620922484360 0xb6390 [0x30]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 29 10 7 620922486018 0xb6410 [0x30]: PERF_RECORD_BPF_EVENT bpf event with type 2, flags 0, id 29 11 7 620922579199 0xb6490 [0x30]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 30 12 7 620922580240 0xb6510 [0x30]: PERF_RECORD_BPF_EVENT bpf event with type 2, flags 0, id 30 13 7 620922765207 0xb6598 [0x30]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 31 14 7 620922874543 0xb6620 [0x30]: PERF_RECORD_BPF_EVENT bpf event with type 1, flags 0, id 32 # There, the 31 and 32 tracepoint BPF programs put in place by 'perf trace'.
