Linux Kernel Driver For Hard-drive Temperatures
-
Reports the temperature of disk / solid state drives
-
If supported, uses ATC SCT Command Transport
-
Reads SMART attributes as fallback method.
If supported, tries to read out:
-
Historic Min / Max Temperature
-
Temperature Limit
-

Building will require upstream commit d188b0675b21
scsi: core: Add sysfs attributes for VPD pages 0h and 89h
and possibly other SCSI core changes.
The temp1_input attribute is always present,
others are only available if reported by the drive.
All temperatures are given in Milli ℃.
