Decoder out of sync and not enough recorded data. about libipt

[loizos01]

I tried this on a different machine with the necessary configuration for it and still got:

In your ptxed command-line --pevent:vdso-x64 --event:tick is specifying --event:tick as vdso file. This is probably not what you want. Note that there is no need to run ptxed as root; just make sure that your files are readable by your normal user.

This pte_nosync error could be caused by failing to read a perf event record. Note that both DATA and AUX buffers may wrap around. The subsequent pte_nomap errors could be a consequence of that.

Hello,

Thank you for your reply, I also tried running without vdso-x64 and the tick config, I think those were there from running the script. I kept in mind that the buffers might wrap around so I made their size large enough. I think there is something else missing that I can't figure out.

Thank you,

Have you tried dumping the trace and sideband using ptdump --sb plus all the --pevent options you used for ptxed? If that doesn't help, you could try debugging into it to see where exactly it returns -pte_nosync.

I haven't, I will when I have access on a computer and let you know, later today. Thank you once again
