After checked the event types, I think "other" samples would include
below raw event types:

  EV_EXCEPTION_GEN
  EV_RETIRED
  EV_NOT_TAKEN
  EV_ALIGNMENT
  EV_PARTIAL_PREDICATE
  EV_EMPTY_PREDICATE

I am just wander if we can use sample.transaction to store these event
types, otherwise, we cannot distinguish the event type for the samples.

I'm not familiar with the meaning of transactions in this context, but
I agree giving visibility of these remaining events is a good idea. I'm
just unsure where to place them from the available --itrace options.

Regarding the "all" events, we thought having quick access to a  global
histogram of all the spe events is useful, and from all the --itrace
options it seemed to fit best under --itrace=o.

Thanks,
German

And it's good fill more sample fields for complete info, like:

  sample.addr = record->virt_addr;
  sample.phys_addr = record->phys_addr;
  sample.data_src = data_src;

Thanks,
Leo
