I have the impression that you are trying to describe a mix of the clock and latency frameworks. Could you elaborate on how your proposal is incompatible with enhancing the clock framework? It looks like you are proposing a brand new shiny thing that frankly I would be happy to leave alone, unless it is crystal clear that the clock fw cannot be improved. The clocfk fw is used for OMAP and other architectures (including SH, iirc) and so far it has provided very good support for our power management needs (Nokia 770 and N800). Currently we are working on DVFS for OMAP2 (see slides presented at the linux-pm summit for OLS 2007 http://tinyurl.com/28tact ) and even if the current prototype is not actively involving the clock fw, our final goal is to make it capable of supporting atomic transactions for changing the core parameters. OMAP3 will require suspend to ram implementation where the content of system memory is retained, while parts or all the SoC are switched off. The plan is still to have a clock fw based implementation (plus interaction with the power rails, of course). I think these are good examples of the non-ACPI systems you are mentioning. To make any proposal that has some chance of being accepted, you have to compare it against the existing solution, explaining: -what it is bringing in terms of new functionalities -how it is different -why the current implementation cannot simply be enhanced You can refer to the linux-pm archives for examples of failed attempts over the last year or so, just search for "framework" in the subject. -- Cheers, Igor Igor Stoppa <igor.stoppa@xxxxxxxxx> (Nokia Multimedia - CP - OSSO / Helsinki, Finland) _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
