Hi,
AFAIU pm branch on linux-omap tree contains required patches, but they are not yet ready for inclusion in upstream kernel.
How is linaro planning to provide pm support for TI omap[34] chips?
Ameya,
TBH, we haven't come to that bridge yet. We're trying to first create a single git tree with support for all partners SoCs.
Kevin's pm branch is definitely very interesting to me personally to enable product-quality PM support in mainline. But we've been too busy ramping up operations to spend any serious amount of time testing his branch with the Linaro kernel.
We are using 2.6.35 mainline as base for meego kernel and facing the same issues for enabling PM support for N900.
The only major feature left in the PM branch is DVFS (including SmartReflex, voltage scaling etc.)
Mainline has support for everything else. IOW, hitting full-chip retention and full-chip OFF in idle and suspend should now be working in mainline. If not, please submit bugs/patches and I will get them merged ASAP.
Is this something that will help Meego/Nokia use Linaro kernels as a baseline?
I guess so :)
I'll have someone look into the PM branch integration as soon as we have the release deadlines out of the way.
Great!
My $0.02...
I would recommend all but very brave souls stay away from the PM branch for any sort of product.
The SmartReflex + voltage + DVFS layers are being completely re-designed and rewritten, so the PM branch is going through lots of churn currently.
