false alarm!

the reason my n900 reboots/crashes while playing vgba is because i played with the configuratio settings! i enabled "14 bit eeprom chip" and "render sound well" so i suggest not to tweak with the config setting in vgba. after setting it to default, i re-enable "smooth imgages" in maemo settings in vgba and went normal even @1.1GHz and contnous playing for 45mins w/out crashing.

so probably the settings. though this reason wont give me an instance on getting back my 1.15GHz settings. sticking with 1GHz.

EDIT: im using the maemo33!

Can I suggest this diff for kernel-config so that the governor can be set from the configs? (I want to be able to use powersave,performance and conservative from configs I'm playing with)

other governors are already supported since power-settings 0.9

@Titan
Is there any chance a future update to settings will enable the changing of sample rate, up threshold, ignore nice load, and avoid freqs with the other govenors, or is there some reason they cant be configured with the other govenors active?
Ive been using the conservative setting for a couple of days now and i think its had a small but positive effect on my battery life, it would be really cool to be able to configure it further.
Thanks

Matt

v33: https://garage.maemo.org/forum/forum.php?forum_id=5683
incl. touchscreen calibration fix!

@matts76: I have asked Matan to extend his patch.

Just installed ver 32 and it is having the old problem when you make a phone call it defaults back to 600mhz after call. Anyone else getting this again?

...hello - v28-v32 did have more or less the same problems; titan wrote about v33 (seems to be stable again) and I just installed (via AppManager) v34.

Edit: using v34 - (using ideal settings) I can not reproduce your problem - jumping back to 600mhz after call; it remains on 850mhz max (actually my mom just called )

I cannot replicate this with v34 (has some minor fix to get touchscreen calibration really working again). there were no OC related changes since v27.

Just updated to V34 and loaded ideal settings. Same thing happens. As soon as I make a call it defaults back to default settings. Very strange if no-one else is having same issues. I have not even modified v34 and just went straight for ideal settings.
