Title:
Backport the adaptive engine from v2.4.1 upstream
Status in thermald package in Ubuntu:
Confirmed
Status in thermald source package in Focal:
Fix Released
Status in thermald source package in Groovy:
Fix Released
Bug description:
Impact:
DPTM provides an adaptive power policy that allows for improved
integration between the platform and the OS. Firmware can provide a
set of complex conditions to the OS, and an OS agent (in this case
thermal_daemon) is responsible for evaluating them, potentially making
use of information that is easily available to the OS and not the
firmware. The agent evaluates each set of conditions in turn, and once
the first evaluates completely it triggers a set of actions.
Fix:
Backport the adaptive engine (and all its dependencies) from upstream
v.2.4.1
Regression potential:
Both Focal and Groovy backports are substantial (Focal in particular is
pretty large), so there's definitely a regression potential.
On the other hand, the entire patchset is a clean backport, taking no
shortcut or trying to adapt any patch, but rather picking up all the necessary
dependencies to make the entire stack apply cleanly.
