From 0a01f59e3316eff9e5d71ee7ac4989622dadb2d9 Mon Sep 17 00:00:00 2001 From: Vadim Pasternak Date: Thu, 24 Aug 2023 15:43:10 +0200 Subject: [PATCH] mlxsw: core_hwmon: Adjust module label names based on MTCAP sensor counter MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ Upstream commit 3fc134a07438055fc93ce1bbacf2702ddd09500c ] Transceiver module temperature sensors are indexed after ASIC and platform sensors. The current label printing method does not take this into account and simply prints the index of the transceiver module sensor. On new systems that have platform sensors this results in incorrect (shifted) transceiver module labels being printed: $ sensors [...] front panel 002: +37.0°C (crit = +70.0°C, emerg = +75.0°C) front panel 003: +47.0°C (crit = +70.0°C, emerg = +75.0°C) [...] Fix by taking the sensor count into account. After the fix: $ sensors [...] front panel 001: +37.0°C (crit = +70.0°C, emerg = +75.0°C) front panel 002: +47.0°C (crit = +70.0°C, emerg = +75.0°C) [...] Fixes: a53779de6a0e ("mlxsw: core: Add QSFP module temperature label attribute to hwmon") Signed-off-by: Vadim Pasternak Reviewed-by: Ido Schimmel Signed-off-by: Petr Machata Signed-off-by: David S.
