Strange:
[root@quaco pt]#
[root@quaco pt]# perf evlist -v
intel_pt//ku: type: 8, size: 112, config: 0x300e601, { sample_period, sample_freq }: 1, sample_type: IP|TID|TIME|CPU|IDENTIFIER, read_format: ID, disabled: 1, inherit: 1, exclude_hv: 1, sample_id_all: 1
dummy:u: type: 1, size: 112, config: 0x9, { sample_period, sample_freq }: 1, sample_type: IP|TID|TIME|CPU|IDENTIFIER, read_format: ID, inherit: 1, exclude_kernel: 1, exclude_hv: 1, mmap: 1, comm: 1, task: 1, sample_id_all: 1, mmap2: 1, comm_exec: 1, context_switch: 1, ksymbol: 1, bpf_event: 1
[root@quaco pt]#
Then:
[root@quaco pt]# perf script --show-bpf-events | head
0 PERF_RECORD_KSYMBOL addr ffffffffc029a6c3 len 229 type 1 flags 0x0 name bpf_prog_7be49e3934a125ba
0 PERF_RECORD_BPF_EVENT type 1, flags 0, id 47
0 PERF_RECORD_KSYMBOL addr ffffffffc029c1ae len 229 type 1 flags 0x0 name bpf_prog_2a142ef67aaad174
0 PERF_RECORD_BPF_EVENT type 1, flags 0, id 48
0 PERF_RECORD_KSYMBOL addr ffffffffc02ddd1c len 229 type 1 flags 0x0 name bpf_prog_7be49e3934a125ba
0 PERF_RECORD_BPF_EVENT type 1, flags 0, id 49
0 PERF_RECORD_KSYMBOL addr ffffffffc02dfc11 len 229 type 1 flags 0x0 name bpf_prog_2a142ef67aaad174
0 PERF_RECORD_BPF_EVENT type 1, flags 0, id 50
0 PERF_RECORD_KSYMBOL addr ffffffffc045da0a len 229 type 1 flags 0x0 name bpf_prog_7be49e3934a125ba
0 PERF_RECORD_BPF_EVENT type 1, flags 0, id 51
[root@quaco pt]#
But:
[root@quaco pt]# perf script --show-all-events | head
Intel Processor Trace requires ordered events
0x2a0 [0x60]: failed to process type: 1 [Invalid argument]
[root@quaco pt]#
So I have all patches but this last one, will test and push Ingo's way
so that we make progress, we can get this one later after we figure this
out.
