[Crash-utility] Trace common and ARM aarch64

Hi folks at crash-utility, I’m just hoping that this address still reaches you who support the crash utility. I am having difficulty digging trace entries out of an ARM (aarch64) dump. I’m not sure whether the problem is in /sys/kernel/debug/trace or in the trace-cmd command. Just using trace-cmd extract, then this hangs: # ./trace-cmd report trace-cmd: No such file or directory [vmscan:mm_vmscan_writepage] function __builtin_constant_p not defined [scsi:scsi_dispatch_cmd_timeout] function scsi_trace_parse_cdb not defined [scsi:scsi_dispatch_cmd_start] function scsi_trace_parse_cdb not defined [scsi:scsi_dispatch_cmd_error] function scsi_trace_parse_cdb not defined [scsi:scsi_dispatch_cmd_done] function scsi_trace_parse_cdb not defined [ras:mc_event] function mc_event_error_type not defined ^Ctrace-cmd: Received SIGINT I have put debugging printf’s in trace-cmd and find it is hanging trying to parse entries in trace.dat. This works okay on an x86_64 system at the same level. The OS: # uname -a Linux panda-aarch 5.3.18-24.46_6.0.29… The trace-cmd is built from source, branch trace-cmd-stable-v2.6, which is the latest version I could successfully build. Do you have any report of a problem with trace and trace-cmd specifically on aarch64? Thanks. -Cliff Wickman
