Sorry about the late reply, we just kind of remembered we have a NNTP/forum assigned to the project... I subscribed to the RSS feed, the turnaround on future replies should be faster
Interesting bug you are pointing out, we have recently moved to a new paradigm to define event columns (among other things) called "event aspects". Without going into all the details, it's a generic interface for defining the contents of trace events, so that we can display/filter etc. them no matter their origin.
It used to be that one could only search/filter on the "base" columns, like timestamp, event type, or contents. The "CPU" column you are looking at is specific to the LTTng trace type, so would not offer filtering and such. By moving to event aspects, this limitation was removed.
If you use a recent version of Trace Compass, I believe this problem should be fixed, and the CPU column, or any other column for that matter, should be searchable and filterable. If it is not the case, please let us know.
