Subject: [PATCH net-next 0/2] mlx5: Expose NIC temperature via hwmon API
Date: Thu, 27 Jul 2023 11:59:20 -0700 [thread overview]
Message-ID: <20230727185922.72131-1-saeed@kernel.org> (raw)
From: Saeed Mahameed <saeedm@nvidia.com>
Expose NIC temperature by implementing hwmon kernel API, which turns
current thermal zone kernel API to redundant.
For each one of the supported and exposed thermal diode sensors, expose
the following attributes:
1) Input temperature.
2) Highest temperature.
3) Temperature label.
4) Temperature critical max value:
refers to the high threshold of Warning Event. Will be exposed as
`tempY_crit` hwmon attribute (RO attribute). For example for
ConnectX5 HCA's this temperature value will be 105 Celsius, 10
degrees lower than the HW shutdown temperature).
5) Temperature reset history: resets highest temperature.
