New Kernel for SS [gen2] gets rid of angry birds lag

[Guest hecatae]

Ss rls5 it is with ahb bus overclocked.

so with rls4 and rsl4b this was working well, but with rls5 it does not. And this kernel does not support ahb overclock

I just had had ahb applied before I installed new kernel. I don't know if that was working. Is downgrading to rls4 without wiping data good idea?

you could there's only two differences between them

I've installed rls4 and applied patch but I can't really see much improvement with angry birds (the newest seasons/easter one). Maybe I'm expecting too much. Thanks anyway.

I had a look at it (kallsyms is a life saver!) and found a few references to adxl34x, which seems to be an accelerometer. Maybe adding a driver for it will fix the problems some users are having with newer models. Apparently, it was merged into mainline in 2.6.36, maybe we could backport it.

That would still leave the significant but not insurmountable problem of finding the I2C address and any GPIOs or interrupts, though. Random guess: could be the same as they used for the lis302dl on older models, seems worth a try. I can't test it though, since I don't have the hardware.

Edit: the main reason for poking around was the claimed performance improvement in Angry Birds. The only thing I found that might be related are changes in arch_idle, but I didn't look into it in too much detail. Then again, I didn't see any improvement in the first place. The level I tested with is 1-21, for which levels are you getting improvements?

It doesn't even work that well with 4/4B, seems fine on early Rio levels, then starts to judder like crazy on the second page of the first set of levels, with lots of lag.

eventually the levels will sort themselves, but it's far from perfect.

In fact, there's not much difference overall, compared to stock 4/4B and this IMO.
