Hi Andrea,
Currently the #ifdef are due to the completely missing API support on the arm/arm64 platform.
Even with PSCI support we will need to write the infrastructure for it then link it in with processor_idle. But arm said PSCI is not compulsary so we we also need to deal with the case without PSCI.
Basically we have a moderate to large chunk of work to do on the backend API for idling on arm/arm64.
Thanks
Graeme

Graeme,
are the #ifdef due to lack of PSCI support? so will be solved in the coming months? or are you referring to other #ifdef? could you clarify?
I remember we also had #ifdef as we were not supporting DMI and dmidecode at that time but now it is working.
I would suggest that you propose a sorting / priority list of #ifdef and related tech topics to look into, then we can take actions and plan accordingly.
thanks for your initiative!

Hi Guys,
Ok, a serious impediment to us upstreaming code is the state of CPU idle, currently we have large chunks of code #defined out for our build.
We need to come up with a plan to solve this!
