Eldar probably has Einstein beat on intelligence by now then :D

Re: Overclocking the N9/N950
 

hey guys,
sorry for resurrecting the thread, just wanted to ask if there is any news of the overclocking front?

Re: Overclocking the N9/N950
 

I guess overclocking will be available only in aegis open mode .

Re: Overclocking the N9/N950
 

Regarding Aegis, sounds like this Inception might solve that problem.

Re: Overclocking the N9/N950
 

looks promising hope to see the results of this soon :D

Re: Overclocking the N9/N950
 

I just looked on wikipedia for OMAP 3630 specs and I noticed that the CPU can go to max 1.2GHz , I guess the N900 has underclocked CPU .

Re: Overclocking the N9/N950
 

There's etc/pmconfig in n9 just like the n900, but modifying it on my stock kernel doesn't seem to do the job alone, I did reboot after modifying, and upon booting the file was still modified, just freq didn't actually reflect the file, maybe in open mode? Would love for ya to try.....
I saw on kernel power 50's I think update list something about removing nokia code for locking(maybe that code blocks the change taking effect), but not sure if its related since kernel powers so choc full of add-ons..

Re: Overclocking the N9/N950
 

etc/pmconfig:
#Power management configuration file
disable_core_off 0
enable_off_mode 1
sleep_while_idle 1
sr_vdd1_autocomp 1
sr_vdd2_autocomp 1
clocks_off_while_idle 1
voltage_off_while_idle 1
scaling_governor ondemand
scaling_max_freq 1000000
scaling_min_freq 300000
sleep_ind 1

I still can't help but think there's more involved than changing the settings in this file, even with open mode. But it's a guess.
scaling_max_freq 1000000 obviously = 1ghz

Edit: ok I see one tiny, tiny piece of the puzzle as I now see.

Re: Overclocking the N9/N950
 

I just don't understand when they don't release something just because someone stupid might overclock their phone and chuck it in an oven while running a prime 95 test. That never happened to N900 (not afaik) and many many many Android phones all over the world are running happily overclocked. (but still can't multitask like N900/N9!)

If some unlucky sod gets their phone somehow damaged physically by overclocking, that's just unlucky. Nothing more. Most likely, it would have died even without overclocking anyways.

I'm just ranting about this post below:

Re: Overclocking the N9/N950
 

1.2 GHz is one of the factory supported frequencies. Stock range is 800-1200. It should be able to clock higher than 1.2GHz.

Re: Overclocking the N9/N950
 

same soc as one in n9 clocks up to 1.3-1.4GHz max in motorolas(that is for stable, some go a bit higher but most are unstable then) so that is probably the max you can expect

Re: Overclocking the N9/N950
 

mmm makes you wonder why people are into open source stuff like Linux when they're so opposed to sharing, not the first time he's taken that viewpoint, but he made a good point I guess, you don't want to be the guy held responsible for frying other peoples phones, thoroughly testing an over clock would be quite the time commitment. At the same time though, anyone capable of flashing their phone knows they have to take responsibility for the risk they take doing it, same should apply for over clocking.
Weird thing I found with rafael2k's idea, which is really appealing since it could be done on stock kernels, this /dev/kmem that we're missing and hence is stopping that route, well the reason /dev/kmem has been removed from most Linux distributions is because it's potentially a major security hole, for root kits specifically.
Trust google to have such shoddy security eh.
We really just need someone capable of doing custom kernels that actually believes in open source principles to release a kernel.

Re: Overclocking the N9/N950
 

Ok I need to bounce this off of someone that actually knows about this stuff, I looked deeper at the milestone over clock that rafael2k found, well it turns out the app they made supports any android phone using Omap3, so the source code for the module itself is actually a collection of modules for other Omap3 phones as well, the one I'm taking interest in is the Droid X one since it also uses the 3630, now besides adjusting it to be loadable in our kernel, I'm wondering if it's just a matter of changing the two physical memory address's or any other minor tweaks and boom, right?
I think I'm game to test it.....

Re: Overclocking the N9/N950
 

If regarding to overclock stuff for milestone, here is another link that might have more info about the project

http://android.doshaska.net/2.6.32oc

kabaldan (or nadlabak) is the well-known dev that makes our milestone's life extended for 2 years more (yes, my previous handset is milestone and it is still being used by me for some applications).

Hopefully the info from the link (and the links insides) could give more hints on how to overclock N9/N950 and improve the performance by overclocking the clock speed, undervolting voltage for saving more battery juice (too low voltage would cause bootloop though) and the governor stuff (seems the governor for N9 default as ondemand).

The overclock for milestone first appeared and installed as apps and then embedded into custom rom for flashing (stuff usually in /system/lib/modules and /system/etc/init.d).

Really looking forward to the overclock for N9/N950

Re: Overclocking the N9/N950
 

Hey so I decided to try this since nobody has released anything yet and with inception, aegisctl and PR1.2 sources available there is no reason to wait longer.
I won't release any binaries until it is confirmed working though, and it's not quite working yet. We have a stupid kernel version nobody else has so it's not quite as simple as just compiling some android module. I tried to start with the cleanest and most up-to-date one I could find at least.
To do this "my way" there is no reflashing, just install inception and the related tools, then you can insmod the two required kernel modules and use a sysfs interface to set the cpu speed.
If anyone knows c and wants to help, the source is here:
https://gitorious.org/opptimizer-n9/...9/opptimizer.c
If you compile and insmod it you can set the rate but it doesn't actually "stick" as far as i can tell because if I set it to 1.2ghz and read it right away it's saying 1.0ghz. I have no clue where to ask for help with this stuff, as usual the meego forum is dead.
It's based on this one:https://github.com/tekahuna/opptimiz...1/opptimizer.c
