Hello,
Below is output of "perf --debug verbose=10 report --stdio > perf_report_dbg.log"
It fails with type 0x70. Is this "ignore packet header "? It should workn because
Earlier I have seen this failing with "Reserved Packet" as h/w was ETM4.2 but it adds "Ignore Packet - 0x70". Now I changed the TRCIDR1 to read out as 0x4.3 (git diff in the end). Maybe I missed something.

Hi All,
Linux h/w trace decoding is working as expected but user-space trace
decoding not showing sybmols (dump raw trace shows h/w trace info) of user-space application/libraries.
Here is how I am using:
- Kernel trace
=> perf record -C 1 -e cs_etm/@tmc_etr1/k taskset 0x2 uname=> tar czf cs_example.tgz perf.data .debug
Transfer cs_example.tgz on x86 machine, untar, copy .debug in ~/ (home)
=> perf report --vmlinux=./vmlinux

=> perf record -C 1 -e cs_etm/@tmc_etr1/u taskset 0x2 unameI verified this command on DB410c, it can record and report well.
=> tar czf cs_example.tgz perf.data .debugTransfer cs_example.tgz on x86 machine, untar, copy .debug in ~/(home)
=> perf reportError:The perf.data data has no samples!# To display the perf.data header info, please use --header/--header-only options.
#But if dump raw trace then I can see ISYNC/ATOM packetsOne potential reason is perf cannot find the correct DSO file. Could
you use below command to output more verbose log?
# perf --debug verbose=10 report --stdio > perf_report_dbg.log
Maybe can find more hints for this failure.
