Public bug reported:
Thermald 1.4.3 contains a delta of bug fixes and support for more recent
Intel processors and kernel interfaces available for the lts-trusty
kernel that are advantageous for HWE enablement and users with newer
chipsets.
Specific fixes that I deem as absolutely necessary
Vivid:
* Fix postinst (original postinst logic was braindead)
* Fix marshalling array error
* Fix regression in exit via dbus message
* New DBUS message to get sensor temperature at a given index
* Fix buffer overrun on a readlink
Trusty, the above plus also:
* Improve accuracy of unit_value calculation
* Null terminate buffer on error return path
* Fix resource leak on file descriptor, close fd on error return paths
* thermald.conf: start only at runlevels 2,3,4,5
* Fix assumption about hwmon0
* Adjust for coretemp path change (kernel interface change)
The update also includes various minor miscellaneous fixes, e.g
* typos in man page
* typos in options such as --ingore-cpu-check --> --ignore-cpu-check
[Test Case]
a) Test on various CPU types, pre-Sandybridge, Sandybridge, post-Sanybridge
modern CPUs (e.g. Ivybridge, Haswell, etc)
Use CPU stressor tools (stress-ng) to force thermal overrun:
1) lts-trusty: does it install and work and perform thermal zone controls
on CPUs where it has kernel interfaces to control the H/W. Can we boot after
it is installed?
2) lts-trusty: does it install and cleanly terminate and not cause any
issues on CPUs where it cannot control the H/W
3) does it work on pre-lts trusty 3.13 kernel with intel_pstate force
enabled to see it works with older kernel in pstate enable mode.
[Regression Potential]
1) Thermald does not exit and tries to control older H/W where it has no
ability to control thermal zones
2) Thermald does not install correctly (to be checked for on older H/W or
newer H/W scenarios)
3) Thermald causes install/boot issues.
