Hi all,
Background of this version:
This is the v8 of the patch set and is has smaller scope. I had to split
the series into two: EM changes and thermal changes due to devfreq
dependencies. The patches from v7 9-14 which change devfreq cooling are
going to be sent in separate patch series, just after this set get merged
into mainline. These patches related to EM got acks and hopefully can go
through linux-pm tree. The later thermal patches will go through thermal
tree.
The idea and purpose of the Energy Model framework changes:
This patch set introduces support for devices in the Energy Model (EM)
framework. It will unify the power model for thermal subsystem. It will
make simpler to add support for new devices willing to use more
advanced features (like Intelligent Power Allocation). Now it should
require less knowledge and effort for driver developer to add e.g.
GPU driver with simple energy model. A more sophisticated energy model
in the thermal framework is also possible, driver needs to provide
a dedicated callback function. More information can be found in the
updated documentation file.
First 7 patches are refactoring Energy Model framework to add support
of other devices that CPUs. They change:
- naming convention from 'capacity' to 'performance' state,
- API arguments adding device pointer and not rely only on cpumask,
- change naming when 'cpu' was used, now it's a 'device'
- internal structure to maintain registered devices
- update users to the new API
Patch 8 updates OPP framework helper function to be more generic, not
CPU specific.
The patch set is based on linux-pm branch linux-next 813946019dfd.
Could you take the patch set via your linux-pm?
I can do that, but I didn't realize that it was targeted at me, so I
need some more time to review the patches.
Thanks!
Gentle ping.
I've resend the patch 4/8 [1] which addresses your comments and
a comment regarding static analyzes conducted by Dan [2].
Do you need more time for this patch set? Maybe you would like
me to help you with rebasing this series? Then please point me
to the desired branch, I am happy to do this.
Regards,
Lukasz
