Unresponsive Sansa with Frequency Scaling

<< < (2/2)

saratoga:
That would work.  I discussed implementing it on IRC a week or two ago, and most people seemed to like the idea.  If you're interested in working on it, we'd accept a well implemented patch (IE one a little more sophisticated then just boosting when the backlight flips and unboosting when it flips off).

Llorean:
I really don't think the speed is problematic enough to warrant boosting while the backlight is on. Saratoga, have you tried a recent build?

Vortex: What theme are you using? When playback is running, about half the time it should be worse because it's unboosted and yet the CPU is in use so less is available.

I don't have a problem with it, which is why I dropped the idea.  And anyway, the idea was to boost when the controls are active, and then unboost immediately afterwards.   That way the power increase would be minimal.  

Llorean:
Minimal, but I still think it might be better to simply spend time optimizing UI code. The worst case situation is going to be during "Unboosted playback," which will go away when Dual Core happens. That leaves the worst case as "Unboosted, no playback" which for me at least is perfectly reasonably speeded right now (turning on and off boost doesn't seem to affect UI speed significantly on my Sansa.) It may be theme dependent, but if it's something that's down to that, it's very possible it can be optimized away.

cpchan:
Just tested it. Mine is still very responsive while playing music.
