Re: [PATCH v8 6/6] cpufreq: powernv: Add sysfs attributes to show throttle stats

Regarding the table-format, it breaks the sysfs's one-value-per-file
rule. So I would still prefer each throttle reason being a separate
file which gives the number of times the chip frequency was throttled
due to that reason. We can live without the per-frequency
throttle stats listed in the throttle_status.

So, would the following be sysfs group structure be acceptable?

$ls -1 /sys/devices/system/cpu/cpuX/cpufreq/throttle_stats/
unthrottle
powercap
overtemp
supply_fault
overcurrent
occ_reset
turbo_stat
sub_turbo_stat

That was suggested for your convenience only, feel free to keep it the
way you want it.

I forgot about the one-value-per-file thing really, but we are using
that for cpufreq-stats as well.

And now that you have mentioned that to me, why shouldn't this stats
directory be moved to debugfs ? :)

We are never going to perform a store here, isn't it ? And is just for
information, nothing more.
