Re: Changes to systemtap transport


I tried the latest CVS and can't get any output from a "Hello World" script now. At first I thought I might have an old staprun installed, which I did. I removed it, but I'm still seeing the problem. What else should I check?

Thanks,
Mike M.

Now the real question. I think it would be best to have some basic
format that percpu data is stored in.  I propose having the transport
automatically put the following header on all data:

struct _stp_trace {
        uint32_t sequence;      /* event number */
        uint32_t pdu_len;       /* length of data after this trace */
};


I have checked in the rewrite of the transport code. I left the above as
the default for now.


"stap -b -DNO_PERCPU_HEADERS" will get the old behavior.
