thanks, so far i too, have no experience problems like stuttering as been reported.

i see you've managed to edit the units in pmconfig, i also been advised to do that, but since that i had a problem when i changed the units in pmconfig (performing SmartReflex) that a re-flash is needed for it to be fixed, I generally avoid settings that needs to touch pmconfig manually via xterm.

i am not saying that this problem will occur to you as well,

if dmesg gives any "warraning" does that mean that kernel/oc is not stable?

yikes!! if i always put my device's CPU to maximum or 100% @900mhz it would set the chip on fire for sure! (well not actually )

thanks,

your kernel gives me absolute results specially in battery life, of course at idle, it consumes less power @ 125mhz, but when i use the n900 at my multi-tasking and max activities @ 900mhz, gives me a downward, almost vertical slope in battery graph.

i activate SmartReflex monday last week, and that ****t up my n900 so i flash new fw and emmc.bin to fix that.

And just now i flash from this dude http://www.farahfa.com/n900-custom-kernels/ his 800mhz (800mhz Kernel Fiasco Image file 125/250/500/550/800)

and did a pmconfig mod: scaling_min_freq 125000 to scaling_min_freq 250000.

And mod
sr_vdd1_autocomp 0
sr_vdd2_autocomp 0

TO

sr_vdd1_autocomp 1
sr_vdd2_autocomp 1

(if i understanding corect SmartReflex= sr_vdd1_autocomp 1
sr_vdd2_autocomp 1)

And the N900 rocks on whid this so far...

Edit pmconfig file or..is other way?

Sorry, all this time i've used lehtos kernel, i just instaled this kernel a few minuts ago (yes, i read a lot os information and the wiki..please give a litle help )
Yes. Temporarily via X terminal or permanently by modifying pmconfig.

Very well nice one for you, in my case, the problems in my smartreflex are more abnormal. at the 3rd reboot, gave me a re-flash, so still quite away from giving etc/pmconfig.

- Implements a schedule (more clock when screen active, less during phone calls, whatever)
- Allows control over other power management functions (ie. ondemand governor)
- Profiles for long runtime or high performance
- "Safe mode" to disable OC'ing if the last reboot was < 5 minutes ago
- An autodiscovery mode that can run on bootup and optimize the various settings until it finds the best that a given phone can support
- (maybe) implement a panel that can control process priorities, renice'ing the camera/video recorder, mediaplayer, etc. to -20 while operating

If there's enough demand for it, I'll give it a shot; anyone interested?
Yeah.. this sounds really cool. Also maybe the benchmarking script could be implemented.

Hi, I am probably being stupid.. the thread is moving too quickly to be able to keep up with everything..

What is wget? cannot find in app manager
In my app manager, there is only the kernel maemo20, not maemo21..

I just dont understand the terminal at all....

can anyone please try to simplify the following:
Create and go to an empty directory first. > where and how??
Make sure wget is installed. > from where??
Thank youuu

edit: im trying to put titan's ideal kernel from http://wiki.maemo.org/Overclocking

im using lehto's kernel by these procedures.

according to what i read, that OC can be reverted back to stock,

so does this mean the OC is permanent until reverted? I also tried rebooting the device after the OC and still the freq shows 900mhz (i OC'd mine to that freq)
