Subject: Energy counters for PMBUS
Date: Fri, 2 Apr 2021 15:19:40 +0200	[thread overview]
Message-ID: <ea24de03-1ef8-fdb8-f4cb-9e06a0090dcf@linux.intel.com> (raw)

Hi,


I am OpenBMC FW developer. We have a use cases which require PSU devices 
energy counters reading. Looks like hwmon:pmbus does not support that 
right now.

Hwmon sysfs 
(https://www.kernel.org/doc/Documentation/hwmon/sysfs-interface) already 
supports energy counter (energy[1-*]_input).

PMBus standard (revision 1.3.1) provides API for getting energy - 
READ_EIN/READ_EOUT commands.

So I am wondering whether we could just add this implementation to the 
hwmon/pmbus/pmbus_core.c? Or maybe there are some constraints?


Thanks

Zbigniew
