printf type functionality from kernel sdt probes
...ype functionality inside the kernel from dtrace probes. Basically I want to dump progress through flow in my device driver. Something like:
DTRACE_PRINTF("Inside chip reset, mailboxes %x %x %x %x %x %x %x %x", mb1, mb2, .....);
...
...
DTRACE_PRINTF("reset failed: reason %s", failure_reasons[err]);
I may have several such probes and they may change very frequently during the development. The dtrace script to enable these probes and dump values can be very simple and will just enable all the probes inside my device driver.
Thanks
Sumit
