stuck at X screen when flash kernel with 176 build(5.0.0.1 recovery).....clean the cache fix the problem
[Nexus One Android Development] evcz:
Thanks! Will give it a try :)
[Nexus One Android Development] sthoeft:
Seems to work great with the 800 mV AVS scaling and the max Voltage of 1225 mV. Now lets see wether it'll really save some battery. Hope so, would be great.
[Nexus One Android Development] acantril:
Really impressed with this kernel and about to donate. I wrote a little blog post highlighting my experiences feel free to read and I hope it helps.

http://www.adriancantrill.me/blog/2010/04/undervolting-the-nexus-one/

Trying the 825mV kernel currently, although its the one with MAX set to 1275 so i'll update tonight.
[Nexus One Android Development] christiankk:
You refer to intersectRavens work as a ROM - it is not, it is a *kernel*.
[Nexus One Android Development] intersectRaven:
I think I just turned red just seeing my alias mentioned on another person's blog. :p
[Nexus One Android Development] hah2110:
How does one download the kernel with max voltage? I don't see links for it anywhere.
[Nexus One Android Development] intersectRaven:
It's in my MediaFire folder (the link for which can be found on the first post). It's still experimental though which is why I haven't announced it. :)
[Nexus One Android Development] hah2110:
File name? I checked there and didn't see it. I'm hoping this one performs better then the diet kernel cause I want to stay loyal to you! Have you considered undervolting?
[Nexus One Android Development] intersectRaven:
Wait, just to make sure we're on the same page here, you're referring to the kernel with the max voltage set to the default stock of 1275 or the undervolted max voltage of 1225? :confused:
[Nexus One Android Development] hah2110:
Undervolted max voltage. Sorry if I confused you. How much power will it save and how much performance will it hurt? Is that all undervolting is? Setting the max voltage?
[Nexus One Android Development] jblazea50:
the new kernel with the undervolted max at 1225 is dated 20100415_1414.zip?

will try it if that's the undervolted max 1225

thanks
[Nexus One Android Development] intersectRaven:
It shouldn't hurt your performance since it is the same maximum voltage that the non-AVS kernel uses for its maximum CPU frequency. :)

See the following quote for the filename:

Yes, that is the undervolted max kernel. :)
[Nexus One Android Development] hah2110:
I'm confused. So why wouldn't you (just curious) have used max voltage AND AVS in the same kernel to start? Is this the definition of undervolting or is this something else?
[Nexus One Android Development] intersectRaven:
My first few versions of AVS was undervolted even at max to 1250. It's just that it could have been a cause for the instability which is why I decided to change it to stock. It's only now that we seem to have a more "stable" AVS that I deemed it ok to undervolt even at maximum frequency. :)

*By the way, I'm experimenting right now at merging both AVS and SVS (non-AVS) so that the maximum voltage for each frequency will be capped at the undervolted voltages specified by the SVS voltage table while still allowing dynamic undervolting below those voltages. This should truly result in maximum power savings. :D
[Nexus One Android Development] hah2110:
Ok so all of the undervolted kernels are UV to what? I noticed better standby time on the diet kernel.
[Nexus One Android Development] intersectRaven:
Well, right now, the latest AVS have a maximum voltage of 1225mV instead of 1275mV with the exception of the 1000mV AVS kernel which I left at stock as a sort of fallback AVS version. :)
[Nexus One Android Development] intersectRaven:
Preliminary tests of the hybrid AVS/SVS kernel seems to be a success! I'll be uploading soon for all those willing to test it. ;)
[Nexus One Android Development] die-hard:
I'm using your latest kernel @875mV and work very fine.

No one reboot no one freeze.

I cant install @850mV, system freeze on cyano ImageBoot.
[Nexus One Android Development] intersectRaven:
That's fine. That means your CPU can't handle anything lower than that. :)
[Nexus One Android Development] hah2110:
What is the difference in an AVS/SVS kernel & max voltage/AVS kernel?

I don't follow.
[Nexus One Android Development] jblazea50:
about to try out the hybrid and see how it goes
[Nexus One Android Development] erasmux:
Could it be that you forgot to update this to your github? I can't seem find the commits for this. If this is so, can you share this fix?

Thanks for your excellent work :)
[Nexus One Android Development] intersectRaven:
Sorry for that! I'll upload the personal-misc branch update soon. I can't upload the main branch since I have special theoretical patches merged in there which I'm not ready to divulge yet. :p
[Nexus One Android Development] schizophrenia:
super fast eh?

so you tested it and the battery consumption is ok?
[Nexus One Android Development] :
The new kernel is fine, although i had a reboot when i tried to USB tether. Wifi tethering works fine.
[Nexus One Android Development] intersectRaven:
Yeah. SmartAssV2 seems in-line with power consumption I've come to expect with SmartAss. :)
[Nexus One Android Development] momomok:
Though it seems more responsive :)
[Nexus One Android Development] erasmux:
Heres an "informal description" I posted for the hero:

The above frequencies are for the hero. Smartass1 was written and tailored for the hero, and never ported by me to any newer device and had some tweaking done which were indeed necessary but I can not guarantee their quality. smartassV2 was rewritten with newer devices in mind.

smartassV2 for the nexus one, uses a ideal frequency of 768Mhz (screen on) and 245Mhz for screen off.
[Nexus One Android Development] evcz:
Looks like rising all the MAX voltages by +25mv using vipermod fixed the random FCs I was having :)

Fingers crossed
[Nexus One Android Development] intersectRaven:
Odd...the max should be set to the accepted stable minimum voltages used by the SVS kernels. :confused:
[Nexus One Android Development] evcz:
well... even SVS kernels were giving troubles to my phone (same FC problems as with AVS) :(

increasing MAX values must have been a placebo: after 30 minutes of usage started getting again force closes on twitter :(

so reverted the MAX values to the kernel defaults and increased all the values (both min and max) by +25... that didn't help either... got an FC on google search while opening it.

now reverted everything back to default...

as for now I can say that the latest kernel is behaving way better (in term of force closes) compared to the kernels I tried last week.

Basically older kernels were always force closing adwex at boot a couple of times before showing the home screen... this last one instead is quite stable and as for now Force Closes are happening less often.

I really have no clue what's going on but it has been in this way since long time (and cm7 official kernel is rock solid)

at the moment I'm testing the latest kernel (2.6.38.8_AVS-CM7_CFS_20110904_0748.zip) with the defaults voltage values, interactive governor (to stress it more), 128 - 998... lets see how it goes in a couple of hours...

(last week kernels were giving troubles even at "on demand", 245-998: adwex/twitter/browser FCs all over)
[Nexus One Android Development] intersectRaven:
I see. If SVS is still giving you problems, it might be your CPU's "bad" for undervolting. Try going to stock voltages and undervolting from there. It'll be a slow process but at least you'll ensure stability on your N1. :(
[Nexus One Android Development] CAL7:
IR.... In the release notes for Wildmonk's version of your kernel, he has:

-msm: Add support for voice call recording​

Can you elaborate on what this is and what can be done with it? In essence, how do I get voice recording?

Update: I found this thread (http://xdaforums.com/showthread.php?t=993793) that explains it all. In short, it works for me on my N1, 5.12 radio, CM7 nightly, 2.6.38.8 kernel.

I am using WM's version, which leaves me with one question: Is the CallRecording mod something that is from CM, or did IR add it, or is it only in the WM version?​
[Nexus One Android Development] heinz gruber:
smartassv2 feels snappier but i can only undervolt by 50mv. when i used smartass 100mv was possible. i wonder what 50mv more meaning about battery life.
[Nexus One Android Development] intersectRaven:
It means one of the frequencies don't like less than 100mV. It only appears while using smartassv2 because it tends to use more of the frequency that has a problem while smartass doesn't. It may be because smartass tends to use the lower frequencies more while v2 is fairly balanced but scales up faster. This is why I prefer manually tuning each frequency and not going for the generic less everything. :p
[Nexus One Android Development] heinz gruber:
a, ok. do you think, battery life is much worser with smartassv2?

tuning each frequency? sound like hard work. i use vipdermod. how do test stability for each frequency? wait for freezes?
[Nexus One Android Development] :
looks like IR added it and WM grabbed it from IR.

strangely w/ IR i can barely heard my voice :0
[Nexus One Android Development] Timdor:
Do you have screenshots of the battery usage charts? If not, look at your battery usage and see if there's anything specific eating your battery
[Nexus One Android Development] intersectRaven:
Minor update to AVS Kernels released! :)

- switched from BFQ to Simple IO Scheduler for testing
[Nexus One Android Development] phewizzo:
Trying out now, thanks IR.
[Nexus One Android Development] schizophrenia:
I uploaded the screenshots

with the same proportions of usages, battery on wifi lasts a lot longer i think.

do you know whats the "green" color on the signal bar towards the end of the 7th hour?

i notice when i go out there are lots of "green" colors on the signal bar.

and for some reason i noticed the signal drops once in a while but it has nothing to do with my mobile carrier as my other phones on the same carrier never has the same problem
[Nexus One Android Development] phewizzo:
My phone has not been sleeping at all with your last 2 kernels, I dont know if its MIUI or the kernel.
[Nexus One Android Development] bassmadrigal:
Did you check spare parts to see what was keeping your phone awake? The last facebook update before today's kept my phone awake the whole time. It was a welcome relief when it went away today after I updated.
[Nexus One Android Development] intersectRaven:
Minor AVS updates! Just some things I've been working on... :p

EDIT: I use this in my N1's CM7

http://intersectraven.euroskank.com...7_11XX/2.6.38.8_AVS-CM7_CFS_20110917_1151.zip
[Nexus One Android Development] k3vink3vin:
Possibly a noob question,

Which kernel should I be using if I want to customise my CPU voltage with IncrediControl? Should it be AVS or CAVS?

I tried CAVS and they seem to work fine together, still testing each frequent steps individually for stability.
[Nexus One Android Development] intersectRaven:
You can use both. The only difference is that CAVS isn't undervolted by default so you will have to set the voltage limits or it will function like SVS. ;)
[Nexus One Android Development] Bohemus:
Anyone else having problems using the stock camera app with this kernel? Using latest 38.8 AVS with a stock rooted 2.3.6 ROM.
[Nexus One Android Development] crachel:
by problems, do you mean force closing? has happened to me before using modified kernels on stock ROMs.. re-flash your stock or move to custom ROM
[Nexus One Android Development] Bohemus:
Yes this is whats happening. Is there a workaround? I like using the stock rooted 2.3.6, can I install a different camera or can you suggest a kernel that has support for EXT4 that will work with stock roms?
[Nexus One Android Development] crachel:
Check your PMs
[Nexus One Android Development] momomok:
I thought this kernel for cm7 or miui only (at least it does not work well on my OxygeN1mod... camera doesn't work and a constant battery drain is observed...)
[Nexus One Android Development] ctfrommn:
Just because a kernel boots on a certain Rom doesn't necessarily mean it will work flawlessly. These kernels are not designed for AOSP and stock derived Roms. They will work but are not going to do a proper job like a dedicated stock built kernel will. Now these are amazing kernels for MIUI and CM base Roms. Instability and high power drain are definitely two of the more common results I have seen. Its hard to find a stock derived kernel as most Roms now are CM or MIUI based. Those that make AOSP Roms almost always include a custom built kernel for that reason.
[Nexus One Android Development] Vimglam:
Started to get problems with WiFi - WiFi does not turn - with latest kernels on Nightlys based on 2.3.6 and 2.3.7 (the last one with 2.3.5 base works perfect).

Anyone else?
[Nexus One Android Development] PlusOne3k:
Yes, got the same Problem. I tried the SZ Kernel from Cheeky which works fine (WIFI could be activated). Still got the Problem with some Call's : Hello can you hear me? Can you hear me? :)

Equal which Kernel i tried, no WIFI could be activated with the latest nightly build.

** Edit : Tried the latest WM Kernel, works fine.
[Nexus One Android Development] scalp42:
I had the same problem but I actually didn't have enough space on my system partition strangely.

The wifi driver was just not installed. Deleted some stuff with the latest nightly and adb pushed it ;)
[Nexus One Android Development] Vimglam:
This is not my case. Have enough space and the driver is there. Just can not turn wifi on using IR's kernel with latest nightlys while it works well with the stock nightly's kernel...
[Nexus One Android Development] PlusOne3k:
Yes, same Problem.
[Nexus One Android Development] ch33kybutt:
Afaik, IR's kernel has a lower wifi voltage compared to CM kernel. Guess those with problems using wifi have hardware that are not able to handle the reduced voltage. But this is mere conjecture, since those complaining have not bothered to provide logcats or dmesgs.
[Nexus One Android Development] Vimglam:
Don't think this is a hardware problem.

I always used IR's kernels before and all went well. Even with the latest kernels. The problem started to appear when upgraded from 2.3.5 based nightlys to 2.3.6 and 2.3.7 based (with 2.3.5. based nightlys all went well).

Will try to provide logcat or whatever (never did before, sorry) when flash nightly again.
[Nexus One Android Development] :
never had wifi trouble.

using two tomato'd routers here in wds setup (wrt54gl and whrhpg54)

and i'm on nightly #208 (2.3.7)
[Nexus One Android Development] PlusOne3k:
WIFI | Kernel | Logcat.

I am using Build 212 actually, got no problems with Wildmonk Kernel.

If i tried to flash the iR Kernel, WIFI could not be activated.

When i try to activate WIFI via Settings, i get the message "failure".

Logcat :

10-07 14:37:29.694: ERROR/WifiService(703): Failed to load Wi-Fi driver.

I tried to push the bcm driver, with this result :

C:\Users\ar> adb remount

remount succeeded

C:\Users\ar>cd \

C:\>adb push bcm4329.ko /system/lib/modules

failed to copy 'bcm4329.ko' to '/system/lib/modules/bcm4329.ko': No space left on device

I deleted some useless stuff and pushed again the driver, WIFI is working like excepted. So its no iRKernel fault - you have to delete some useless stuff on your system partition (system/app - dont know which stuff is essential for you or not - i deleted "rommanger" and "filemanager oi".)

[Nexus One Android Development] intersectRaven:
You should just test the AVS versions if you're new. Once you've read up on AVS, then you can try customizing your voltages. :)

[Nexus One Android Development] wenchien:
Hi @IR,

Do you have a non-zero /sys/kernel/mm/cleancache/succ_gets ?

It seems that mine is always zero... guest this means cleancache/zcache does not work as expected?

Would you consider making a version for AOSP-ROM? :P
[Nexus One Android Development] uoY_redruM:
I echo that one.
[Nexus One Android Development] intersectRaven:
I'll have to rollback trying to enable cleancache in YAFFS. It's too convoluted to modify. :p Anyways, I'll retain it for EXT3 and 4 since they're the ones who have them enabled in the mainline anyways. :)

SD card Read/Write Speed

Hi IR,

not sure if this has been addressed before, but i did use the "search" before i post lol

If I use CM7.1 kernel, my class 10 sd card speed is good; 10Mb/s and 32Mb/s;

however, after installing IR kernel, it drops to half, like 5Mb/s and 5Mb/s or so...

just wiped everything starting from scratch to test... i am very positive the only difference is the kernel when i did the test

used free app "SD Tools" to test

it is a great deal to me because i use S2E and have dalvik cache and other things on SD, greatly affect I/O performance when the Write rate drops!

On the other hand, I love your kernel, so...

Please help! Thanks in advance!
[Nexus One Android Development] DaXmax:
Have u tried sd booster?
[Nexus One Android Development] kaiser_tytnii:
