Hmm, having unstable SR with "default" profile is really strange.

Also I need your /dev/mtd2.

Hmm, I don't think I have the stock kernel installed anymore. I will try to find out how to revert so I can get you those numbers. I should mention I believe I have one of the worst N900s ever produced - when I first overclocked it a couple of years ago I had to boost the voltages above all of the values in {ideal, lv, ulv, starving} by trial and error to achieve stability, and always without SR. I hoped that I might be able to use SR with frequency range 500-600 just to extend battery life, and then manually OC when I wanted to do something more CPU-intensive.

And the FM transmitter has never worked, no matter which version of fmtxd I tried! :(

I recently bought a 2nd N900 for a fraction of the price of my older one, and everything (including SR) works very well on it.

Do you use ramzswap by chance?

No, I don't use it anymore - I found it didn't provide any benefit. I reflashed this phone 1 week ago and have been fairly conservative with what I have installed since.

EDIT:

There is really something wrong here, SR VDD2 didn't change through KP versions.

Hmm, okay. In the past I only ever enabled VDD1 (VDD2 was super-unstable on my device), so that may not be relevant.

Re: [Announce] kernel-power stable v51 in Extras-Devel

Hmm, I can't seem to revert to the stock kernel using the instructions here:

Re: [Announce] kernel-power stable v51 in Extras-Devel

I've heard that someone in xda have ported the upstream ondemand governor code from latest linux kernel(and a lot else).
Is that possible for power-kernel? Will that bring us any improvement in daily use?

Re: [Announce] kernel-power stable v51 in Extras-Devel

Given that the N900 already jumps to OPP5 every time you use the device, I don't think much would change.

Re: [Announce] kernel-power stable v51 in Extras-Devel

Ah, freemangordon, I'm running CSSU-thumb, so I guess uninstalling the power kernel to get the info you want from /sys/power/efuse_vddN is not possible.

If I give you a copy of the device file /dev/mtd2 whilst running under power kernel is it any help?

Yeah, flashing stock is not a good idea :)

Anyway, I still want your efuse values along with your "kernel-config show" output when SR VDD1 is on and tho profile you use to OC and/or undervolt. I want to compare what SR thinks is OK for your device to what is OK in practice. And maybe it is time to do the same for VDD2 SR I did for VDD1 SR. You and your "very bad" device could help a lot for that.

Going back I think I made a general mistake with SR - I preferred slightly better battery life instead of 1-2% worse and a bit higher voltages. But fortunately this is easy to be fixed.

Okay, so with my currently installed KP51 using my own stable undervolting/overclocking profile:

Code:

ash-n900:~# cat /sys/power/efuse_vdd1

0078a384

0089939e

009a82a6

00aaed99

00aada8e

00abb6f2

00aba3db

00ab9ad1

00ab92c6

ash-n900:~# cat /sys/power/efuse_vdd2

0099c485

009a8ec3

00aac695

ash-n900:~# kernel-config show

current kernel configuration:

current frequency: 805

supported frequencies: 125 250 500 550 600 720 805 850 900 950 1000 1100 1150 

min. frequency: 250

max. frequency: 805

avoid frequencies: 125 

active frequencies: 250:38,180 500:34,360 550:38,400 600:42,430 720:50,520 805:54,600 850:60,600 900:60,600 950:60,600 1000:60,600 1100:72,600 1150:72,600 

SmartReflex VDD1=0, VDD2=0

governor ondemand: ignore nice load= 0, up threshold= 95, sampling rate= 300000, powersave bias= 0

And with my modified copy of the 'default' profile with SR VDD1 enabled:

Code:

ash-n900:~# cat /sys/power/sr_vdd1_autocomp 

1

ash-n900:~# cat /sys/power/sr_vdd1_dsp_boost 

125

ash-n900:~# cat /sys/power/sr_vdd1_voltage 

48

ash-n900:~# cat /sys/power/sr_vdd2_voltage 

44

ash-n900:~# cat /sys/power/sr_vdd2_autocomp 

0

ash-n900:~# kernel-config show

current kernel configuration:

current frequency: 500

supported frequencies: 125 250 500 550 600 720 805 850 900 950 1000 1100 1150 

min. frequency: 500

max. frequency: 600

avoid frequencies: 125 250 

active frequencies: 500:48,360 550:54,400 600:60,430 720:60,430 805:60,430 850:60,500 900:60,500 950:60,500 1000:60,500 1100:72,520 1150:72,520 

SmartReflex VDD1=1, VDD2=0

governor ondemand: ignore nice load= 0, up threshold= 95, sampling rate= 300000, powersave bias= 0

What should I do with the device file /dev/mtd2?

as root do "cat /dev/mtd2 > oops.log" without quotes, compress oops.log using whatever you like and upload it here.

Also I want kernel-config show output with SR VDD1 enabled when the device has run for a couple of minutes with it on, so SR had calculated the voltages.

does anyone know if the fcam drivers will be compatible to the power kernel (or the power kernel to the fcam drivers) again any time soon?

Cam on my N900 only works with standard drivers on pk51.

Would be cool if I could use blessn900 again :)
Thx!

Fcam-drivers from extras-testing (or devel I'm not sure) work with kp and kcssu. They are pretty safe to use, haven't got any issues with them nor I've heard anyone having problems)
