KeyError: u'MATRIX_REQUEST' about pmu-tools HOT 4 CLOSED

The row contains:

{u'MATRIX_REG': u'0,1', u'BitIndex': u'0', u'Type': u'1', u'BitsNotCombinedWith': u'Null', u'BitName': u'DEMAND_DATA_RD'}

from pmu-tools.

Looks like https://download.01.org/perfmon/HSW/Haswell_matrix_bit_definitions_V15.json contains a file in a format which is not expected by ocperf.py:

[
  {
    "BitName": "DEMAND_DATA_RD",
    "BitIndex": "0",
    "Type": "1",
    "MATRIX_REG": "0,1",
    "BitsNotCombinedWith": "Null"
  },
  {
    "BitName": "DEMAND_RFO",
    "BitIndex": "1",
    "Type": "1",
    "MATRIX_REG": "0,1",
    "BitsNotCombinedWith": "Null"
  },
...

from pmu-tools.

A workaround for this is to clear the offcore file so that it doesn't upset ocperf:

echo "{}" > ~/.cache/pmu-events/GenuineIntel-6-3C-offcore.json

from pmu-tools.

This was a bug in the mapfile.csv. Should be fixed now, but will take
some time to propagate to the mirror. For now your workaround should
suffice (except you won't see offcore events)

Thanks!
