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.
How about deal with the case without PSCI for upstreaming code first? If the this version of ACPI code is accepted, we can send another patch set for PSCI. In this way we can reduce the complexity for upstream.
If anything I can do for upstream, I would be happy for that :)
Thanks Hanjun
Basically we have a moderate to large chunk of work to do on the backend API for idling on arm/arm64.
Thanks

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!
