the problem is that "perf list" doesn't show any UNC_xx events.
and I cannot profile UNC events, e.g.:

"perf stat --pfm-events UNC_DRAM_OPEN:CH0 /bin/ls"

gives me complains:

"unsupported event UNC_DRAM_OPEN:CH0"

So your processor is correctly detected by libpfm4. You have all the
uncore events
available. So what is exactly the problem you're running into and with
which command?
