Subject: [PATCH net-next 0/3] mlxsw: Thermal and hwmon extensions

From: Ido Schimmel <>

This patchset from Vadim includes various enhancements to thermal and
hwmon code in mlxsw.

Patch #1 adds a thermal zone for each inter-connect device (gearbox).
These devices are present in SN3800 systems and code to expose their
temperature via hwmon was added in commit 2e265a8b6c09 ("mlxsw: core:
Extend hwmon interface with inter-connect temperature attributes").

Currently, there are multiple thermal zones in mlxsw and only a few
cooling devices. Patch #2 detects the hottest thermal zone and the
cooling devices are switched to follow its trends. RFC was sent last
month [1].

Patch #3 allows to read and report negative temperature of the sensors
mlxsw exposes via hwmon and thermal subsystems.


Vadim Pasternak (3):
  mlxsw: core: Extend thermal core with per inter-connect device thermal
  mlxsw: core: Add the hottest thermal zone detection
  mlxsw: core: Add support for negative temperature readout
