The CSV output is intended as an alternative to default output format to
facilitate easy importing into spreadsheet applications or further
processing with scripts.
The file contains one or more of the tables (C-state/P-state/wakeups). In
case of multiple tables, they are separated by empty lines.
For each table, the first line is the name of the table, i.e. one of
C-State Table
P-State Table
Wakeup Table
The second line is a header line that describes the names of fields in the
table., E.g.
cluster,core,cpu,C-state,min (us),max (us),avg (us),total (us),hits,over,under
The following lines are either topological names or data entries. The data
may relate to a cluster (package), a core (collection of hyperthreaded cpus)
or a cpu. A cpu belongs to a core (hyperthreading) or a cluster (no ht).
A core always belongs to a cluster.
Topology names:
Cluster names are in the first column and all other columns are missing.
Core names (if present) are in the second column and all subsequent
columns are missing. The first column is empty.
Cpu names (regardless of existence of core layer) are in the third column
and all subsequent columns are missing. The first and second columns
are empty.
Data lines:
Each data line begins with 3 empty columns (reserved for topological names)
and are followed by report-specific values. For meaning of the columns,
refer to the header line for the report.

(more cores and cpus follow)

The core 0 (belonging to cluster A) has been in C6-IVB for a total of
14.99 seconds during 1187 separate idle periods.
The cpu 0 (belonging to core 0) has been in 3 different idle states as
detailed.
The cpu 4 (belonging to core 0) has been in C6-IVB for a total of
15.01 seconds.
