Subject: Re: cpufreq support for the Beagleboard.
Hi,
thank you for your fast answer.
I've been testing the repository you pointed me and I found that only
300MHz and 600MHz can be selected in the Beagleboard xM.
Couldn't we work until 1000MHz?
1G is disabled by default in OPP table I suppose. Pls enable it (in
omap36xx_opp_def_list) if your board supports it.
My understanding was that the mainline kernel needed support for
SmartReflex 1.5 and Adaptive Body Biasing (ABB), as found in TI's
linux-omap-psp 2.6.32, before it was safe to enable the 1GHz OPP on the
DM3730 (for e.g., Beagleboard xM). Is this not the case? Can we really
just flip the bit in the OPP table?
Do you know what's left for those patches to enter mainline? Is
anybody working on it?
OMAP cpufreq is undergoing some architecture/design changes and this is
WIP.
Vishwa
Thanks,
Matt
