From 2d8ce8c9d4b25b88eb4aa6bc52492eb7e0ae1dab Mon Sep 17 00:00:00 2001 From: Sreekanth Reddy Date: Mon, 12 Jan 2015 11:38:56 +0530 Subject: mpt2sas, mpt3sas: log exceeded temperature thresholds This patch will log a message when driver receives "Temperature Threshold exceeded" event from any temperature sensor. The message will look similar to like: mpt3sas0: Temperature Threshold flags a b c d exceeded for Sensor: x !!! mpt3sas0: Current Temp In Celsius: y where a b c d are threshold flags 0 1 2 3 Change_set: 1. Get the number of sensor count of this IOC by reading IO Unit page 8 at driver initialization time. 2. Also unmask the Temperature Threshold Event at driver initialization time 3. Whenever a MPI2_EVENT_TEMP_THRESHOLD event is received from the firmware, then print the sensor number, the maximum threshold number it has exceed and the current temperature of this sensor.
