update: n8x0 idle power problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi, All,

Regarding the idle power problem I've mentioned in a mail last weekend:

http://marc.info/?l=linux-omap&m=125634121921583&w=2

I have spent more efforts on this problem. By comparing with PM debug
messages from Maemo kernel, it seems full-retention in linux-omap
2.6.28 has no problem on n810. Moreover, I've observed that l-o kernel
consumes more power in other power states (e.g. when USB is plugged
and the screen is dim but not off, Maemo kernel takes ~90mA@xxxx while
l-o kernel takes ~180mA@xxxx). As a result, I think the extra power
may not be consumed by OMAP processor core but by some device.

I try to disable some devices in kernel configuration (BT/MMC/USB),
but it does not work - l-o power consumption is still significantly
higher than Maemo kernel.

Would you please offer some suggestions? Thanks

Best Regards,
