Re: [tracecompass-dev] Custom page fault histogram

At the moment, not yet, but if you trace page faults as a context, they
will appear in the performance counter view, the difference being that
it will be a line chart instead of a bar chart.

look up

lttng add-context

The contexts of interest are:

perf:thread:page-fault
perf:thread:faults
perf:thread:major-faults
perf:thread:minor-faults

we have an example trace that already has them called "kernel-vm" where
you can see what the trace will look like.
