Thanks for the pointers. I gather that user level tools might be able to format the
msr trace output in a more convenient way (perhaps as generated by the custom driver trace)
There is still the other convenience of not having to look-up the
MSRs addresses corresponding to all the individual tests and setting the filter on them to
analyze IFS test activity (rather than enabling it via echo 1 > /sys/kernel/debug/tracing/events/intel_ifs/enable)
Agreed that for array test it is a single MSR. For other test, it is 2 separate MSRs ... there could be additional
tests in the future.
