This patch series implements various improvements for the k10temp driver.
Patch 1/4 introduces the use of bit operations.
Patch 2/4 converts the driver to use the devm_hwmon_device_register_with_info
API. This not only simplifies the code and reduces its size, it also
makes the code easier to maintain and enhance.
Patch 3/4 adds support for reporting Core Complex Die (CCD) temperatures
on Ryzen 3 (Zen2) CPUs.
Patch 4/4 adds support for reporting core and SoC current and voltage
information on Ryzen CPUs.
With all patches in place, output on Ryzen 3900 CPUs looks as follows
(with the system under load).
k10temp-pci-00c3
Adapter: PCI adapter
Vcore: +1.36 V
Vsoc: +1.18 V
Tdie: +86.8°C (high = +70.0°C)
Tctl: +86.8°C
Tccd1: +80.0°C
Tccd2: +81.8°C
Icore: +44.14 A
Isoc: +13.83 A
The patch series has only been tested with Ryzen 3900 CPUs. Further test
coverage will be necessary before the changes can be applied to the Linux
kernel.
Hello everyone, I am the author of https://github.com/ocerman/zenpower/ .
It is nice to see this merged.
I just want to warn you that there have been reported issues with
Threadripper CPUs to zenpower issue tracker. Also I think that no-one
tested EPYC CPUs.
Most of the stuff I was able to figure out by trial-and-error approach
and unfortunately because I do not own any Threadripper CPU I was not
able to test and fix reported problems.
Ondrej.
