Flashed my DHD to this kernel, working pretty damn smooth - Thanks Kamma :D.

I'm interested in how overclocking affects battery life?

I want to get the best battery life possible (1Ghz minimum).

Is it better at 1.5, 1.1 or 1Ghz? Which scaling options do I use?

From what I've read I'm at 1.1 with interactive atm.

I use the SetCPU profiles for when the screen is off and battery is <30% (ondemand for screen off and interactive for <30% or is that bad...?) so I am only worried about the battery life when the device is in use, and if someone could outline what is better for me that would be great.

Thanks

[Desire HD Android Development] kill4l:
i flashed via CW but i got some lags so is there any way to go back to buzz from this kernel?

i'm using CW.

i get boot loop when flashing via cw buzz kernel or stock. thx in advance.
[Desire HD Android Development] jkoljo:
Use kernel update utility. Zero bootloops so far.
[Desire HD Android Development] iraqisniper:
?

Can u make uv on cwm?
[Desire HD Android Development] cubitusclaudius:
(it was post No. 84, long long time ago) Nobody answering? I'm interested. asked the same question and got no answer.

will OTA from HTC crash with stock ROM and new kernel?

If not, I suppose we'll have to re-flash the kamMa kernel?
[Desire HD Android Development] zantekk:
I'm not sure if OTA will work with custom kernel, but after ota update you have to root again.make a backup and try it ;)
[Desire HD Android Development] cubitusclaudius:
You mean the phone will be unrooted, Hboot s-on and CWM deleted?

Can someone else confirm?
[Desire HD Android Development] cubitusclaudius:
Original ROM 1.32.405.6 . I didn't note the original kernel. is there more than one possible? I can have it of course by recovering my older backup (before KamMa kernel) and the returning to my new backup. but if somebody knows...

is it dangerous to recover only kernel (older and then newer) ?
[Desire HD Android Development] MrYuiM:
This kernel is awesome. Thanks Kamma, average quadrant score of 3000 on interactive and battery is getting better :D
[Desire HD Android Development] cubitusclaudius:
which one ? UV or noUV?

what's your rom?
[Desire HD Android Development] K Dotty:
I can only get 2600 in quadrant :(

ROM; LeeDroid v1.2

kernel noUV.

Does the uv kernel run faster than the non-UV?
[Desire HD Android Development] MrYuiM:
Nouv, leedroid 1.2. I flashed it using the kernel.update utility but I had to extract it and select the kernel and zimage manually, but its all working :)
[Desire HD Android Development] kamma:
what governor ?
[Desire HD Android Development] cubitusclaudius:
for me same result.~ 2600. Interactive

^ this version doesn't come with undervolt at all? does kamma have any undervolted kernel? very interested to try one. i'm on cyanogen mod 6.

thanks :)
[Desire HD Android Development] kamma:
you can undervolt on your own - thats the added value of this version

this kernel is for Sense ROMs. its really probable that you have issues with CM ROM.
[Desire HD Android Development] supersomething:
thank you sir, i will try this when i'm going to flash some sense roms :)
[Desire HD Android Development] hamdir:
will this kernel work on version 1.72 and still have wifi?

also kamma since your kernel is for sense and has good UV policy is it possible for you to divide it into two versions, CFS and BFS? like ziggy does? :)

its the only issue stopping me from using your kernels

thx

caller can not hear me with this kernel

Testet the kernel on my selfmade rom, but i have a big problem.

If I make a phone call, the caller can not hear me, but I can hear him.

After flash the stock kernel back to phone, all is ok.

Ahh, my rom is a selfmade rooted stock 1.72.405.3 Froyo 2.2.1 rom without any over mods.

PS: I have the same problem with apache14 buzz kernel. :mad:
[Desire HD Android Development] kamma:
i notice it so...

try to find out, where is the problem...
[Desire HD Android Development] igor.tonky:
this kernel is so cool, allowing to play with OC/UV, thanks alot kamma!

reporting here that my phone can hold some nice UV! running just fine, with 3005 in quadrand 245-1.53 ondemand.

here's the script to put on your sd card, and use like this:

sh fs 245760 900

this will set your 245760 frequency to 900 mV.

run it without arguments and it will print current volatges table.

save this as "fs" file on your sdcard and run

chmod +x /sdcard/fs

#!/system/bin/sh
if [ -z "$1" ]
then
cat /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels
else
echo "$1 $2" > /sys/devices/system/cpu/cpu0/cpufreq/vdd_levels

thanx

but same problem here
[Desire HD Android Development] Isotopes:
I thought I am the only one with this problem. :)

I tested any different radio and think this is not a problem with the flashed radio version. i flashed 3 different radio version (26.04.02.17; 26.04.03.30; 26.05.02.15) and nothing work when the kernel is flashed. When i flashed back the stock kernel all is running fine.
[Desire HD Android Development] MrYuiM:
So about this custom voltages thing, what exactly do you have to do, I'm a tad bit confused bout it :/

Sent using my two thumbs.
[Desire HD Android Development] vuedesprit:
just a question about the UV feature, so after installing the kernel should we see any change in setcpu, like voltage settings, or should we add the voltage settings as a script file manually?

and say we didnt mess with the voltage settings, will we get the same effect as the older kernel revision with no UV
[Desire HD Android Development] vyruzj:
Setting voltage

Guys,

Now with 1.3 version of the kernel we can change the voltages on the fly. We can change the voltage by running the following:

What i am doing now is create a script to set the voltages during boot with a script. Contents of script should like this:

To run at boot, place the script in /etc/init.d

hmmmm..... i have no issues with the kernel. Running LeeDroid v1.2 with kamma's v1.3 kernel.

To overclock you need to install setcpu and set the range from their. The kernel just unlock the extra voltages to five you. Bigger range...

but It looks that voltage levels are too low with the frequencys, I think.

Continuing with newest 1.4 Kamma's kernel on my stock rom, i would like at first to thank the author for is good job.

Hey guys!

I Just flashed Kammas Kernel v1.4 over my Core Cell HD 1.5.

But after 10 Benchmarks i still stick on about 2500 Points. Anything I'm doing wrong?

Overclocked to 1497MHz Ondemand (SetCPU).

€: HTC Sync synced. When I stopped it, my Benchmark results were about 3000. :)

But one Question:

Do I HAVE to push the "New Wifi modules"?

Everything works fine without them. Will I have changes when i pushed them on?

€: Ok, I HAVE to push :D They don't work... :D

Well... I pushed the files now... But my menu is kind of violet now. -.-

After reboot wifi works now (and nothing's violet) but these steps don't work:
