Subject: [PATCH 0/6] RFC: hwmon: few improvements to amd_energy driver
Date: Sat, 5 Sep 2020 20:02:24 +0530 [thread overview]
Message-ID: <20200905143230.195049-1-nchatrad@amd.com> (raw)
Hi Guenter,
Would like to know your feedback on the following features
for the amd_energy driver.
1) Sysfs entry for dumping energy counters of all the cores
- On latest CPUs there can be as many as 128 cores.
An ABI for dumping all 128 counters using seq_printf()
to a debugfs/sysfs file would save a lot of cycles.
2) Enable/Disable the accumulation, Disabled by default
- The accumulator thread may introduce some noise.
Providing a knob to enable/disable (start/stop) the
accumulation in software.
3) Accumulator Interval change based on reported resolution
- Frequency of the accumulator thread can be set during
the probe based on fine grain (1.625 micro J) or course
grain (0.125 milli J) resolutions.
