The stock kernel is fast but I'd like to be able to O'C to 2ghz on CM7. Someone said it was easy, just edit some values in a table, idk what table and I don't have linux so I'm clueless
[Desire HD Android Development] nteeb:
Thanks, great news!Gonna try it right now...:D

It is cfs, isn't it? Just because bfs scheduler was mentioned in key kernel features.
[Desire HD Android Development] kamma:
for now, there is only CFS version...

BFS version is gonna be later...

[Desire HD Android Development] ArtaxXP:
could you maybe compile a kernel with support for non-sense roms like cm7 ?

just because of the possibility to overclock more than 1.53ghz...

would be awesome!

Tested this briefly and got "hit hard" by a youtube app bug...

On playing any youtube video (using v2.1.6) , I get a blank (black) screen with audio only.... no video.

Even after exiting the app, the sound continues and will only be stopped by a reboot.

Has anyone else experienced this ?

Do you have any idea why ext4 is not working? I' ve flashed android revolution and after boot it was ext4. Then I just flashed kernel 2.0 and ext4 had disappeared. Also there is no bfq io scheduler available. I think something is wrong.
[Desire HD Android Development] kusa:
Hi, version 2 is base on the new kernel source. Can i flash it on 1.32 Rom or do i have to get 1.72 Rom??

@kamma

which one is the battery saver here?

coz you dont have smartass on your kernel im confused on what to use O_O
[Desire HD Android Development] Try4Ce:
Currently I am running LeeDroids faboulus kernel. Really fast and stable so far.

But kammas kernel always has been a favorite of mine as well.

Just want to know how it performs (CFS) and what the battery usage is like.

BFS builds wont be flashed on my DHD. Those lags always annoy me like hell, even tho it causes great benchmarks. Benchmarks are not very important, as long as the phone itself doesnt run smooth. BFS always screws up for me.

And as far as I know, BFS is not very popular in the Desktop Linux World as well...
[Desire HD Android Development] kamma:
i completely agree. BFS is great for benchmarks, but CFS is much smoother.

Now i run CFS with idle consumption about 3-5mV, which is fabulous for me... :)

you have to install busybox...
[Desire HD Android Development] combat goofwing:
thank you so much you are right you have to replace the last line of point 6

"cp /data/local/bcm4329.ko /system/lib/modules/"

with

"busybox cp /data/local/bcm4329.ko /system/lib/modules/"

im going to go through the whole process i followed and write a newbie newbie for ultimate dummies guide if some one would like to check it when done and if its ok maybe it can be posted up

Now for my last questions about profiles

with this kernel what profiles are people using and why?

am i correct in saying that by default this kernal runs at 235min 1459 max and will run at that by default if the speed is selected in cpu

ive added a screen off profile set at 235 max and min interactive priority 50

any other profiles advice to get better battery usage and fast stable cpu with this kernal would be great also what is a safe temp for this to run at

thanks to all who help sort out my oc and wifi issues
[Desire HD Android Development] Andy:
I'm not sure whats wrong, but whenever I check "Set on Boot" within SetCPU, my DHD freezes. It doesn't matter what speed I select. Once I check it, it freezes. It works great otherwise. Would a logcat provide any insight into what's happening?
[Desire HD Android Development] low-dogg:
THX! one question though..

This really works great 2657 in quadrant:)

One question.. Can i use the build in system update with this kernel?

I mean if HTC sends out a new OTA update, can i update? And will i have to change the kernel again, root again and so fourth?

Or will the update fail like it did when i used custom roms on my desire?

Hope someone can answer it because i can't find any info on it when searching..

And hey! thx again, i love this device, i loved it before and now i love it even more!
[Desire HD Android Development] kamma:
Changelog v0.3

- updated kernel to version 2.6.32.25

- back to stable voltages (but still little lower than in v0.1)

With this kernel version you need to install new wifi module included in package (bcm4329.ko)
[Desire HD Android Development] low-dogg:
Why new kernel?

EDIT: Trying it now.. So far works great but can't see any changes from v0.1
[Desire HD Android Development] arielext:
updated to 0.3 and patched new wifi driver: works like a charm!

Thx for the new kernel!
[Desire HD Android Development] low-dogg:
Hmmm i can't seem to use setcpu anymore? when ever i change cpu speed nothing happens and it always runs at full speed? any suggestions?
[Desire HD Android Development] :
same here with setCPU not working with kernel to decrease OC
[Desire HD Android Development] kamma:
try this rebuilded version...

after flash and boot, open SetCPU and go through - Menu - Device Selection - Autodetect Speeds Recommended
[Desire HD Android Development] low-dogg:
Trying itw:) thx!

[Desire HD Android Development] low-dogg:
Touchscreen issues?

Hmmm i don't know if this has something to do with the new kernel or my settings, but when i wake up my phone it sometimes takes a while to be able to use the touchscreen.. It's only a couple of seconds but a little bit annoiyng..

My setup is that whenever the screen is off setcpu can max use 368mhz

And when the screen is on it's full speed ondemand.
[Desire HD Android Development] RD1945:
Maybe it has something to do with the ondemand governor?

Try setting it on interactive.

Second, maybe the screen off speed is too low. Try setting a higher value.

I don't have this problem so don't know of anything else for you to do about it.
[Desire HD Android Development] RD1945:
I 2nd that.

I had the same problem. All seems fine now.
[Desire HD Android Development] low-dogg:
Hmm yup will try that.

However:).. New problem.. It seems that now my proximity sensor does not work?? when i answer a call the screen stays on and the sensor does not work at all?!?

Any ideas? i have heard that many people had this problem, but it was fixed with the OTA. But i have updated to the newest OTA.

Could it have something to do with the kernel?

EDIT: Tried to roll back to 0.1 but i have the same problem now?!?!?? i have never had this problem before, any suggestions?
[Desire HD Android Development] kamma:
i dont have this issue with proximity sensor. even with new or old kernel version.
[Desire HD Android Development] bariz143:
hi .

just did the s-off guide and it worked fine.

i tried your 1.49kernel and it worked fine to, but now i only get fc all the time and my wifi is gone. tried to push the wifi but now it says it doesnt find any device.

what should i do plz help.
[Desire HD Android Development] kamma:
you have to push the latest module. (from v0.3 zip file)
[Desire HD Android Development] bariz143:
yes thats the one im using

how do i flash to the original kernel that came with my desire hd???
[Desire HD Android Development] low-dogg:
Hmm wierd installed 0,3 again, now it works but it needs pretty strong light to work.. Guess it has nothing to do with the kernel..

EDIT:

Okay i don't want to spam but here is some info:)

When i set my setcpu to interactive/245/245 when screen off, i have the proximity problem.. If i change all my profiles and the main profile to ondemand it works like a charm! I'm thinking that maybe it's running to slow or don't get enough juice when in off screen mode, for the proximity sensor to work right.

Just a heads up if anybody else is experiencing wierd problems:)

THX for the kernel keep the updates coming!! :)

[Desire HD Android Development] boarne71:
Thank you so much for this kernel v04 that i just installed, seams to work fine and i hope it's a stable one, it seams to be stable so far and im testing it hard.

One thing, i cant set my set cpu at 1490 it seams to ignore that and bumps to max all the time, i use ondemand and it wont listen to me anymore :( i havent checked if my offscreen 245mhz settings will work or be ignored to.

Any ideas on how to make this listen to my set cpu setting in main setting on set cpu ?

And i saw just now that yet another even faster kernel is made, my good this is starting to get a littlebit to much now isnt it ? my good 3030 in quad, please this is just a phone.. a nice one at that but these speeds are getting a littlebit over the edge isnt it ;)

All i want is to get my cpu really fast, but most of all it has to be stable and reliable and not to consume to much battery, is my v04 a good choice for me then ?
[Desire HD Android Development] kamma:
1st of all, when you install new kernel, always do this:

"open SetCPU and go through - Menu - Device Selection - Autodetect Speeds Recommended"

2) if you prefer less battery consumption, do not use max speed

3) the best performance you get with Interactive governor (i use only this one)

here are my SetCPU profiles:
[Desire HD Android Development] brolee93:
thanks good kernel .

And with interactive profile in advanced i put what number by debault is :80000 it is correct ?

I will use those settings you showed me, and see how it goes. My god this is fast and seams to be very stable. I have really made it work hard without any hickups at all, me so happy now :)
[Desire HD Android Development] bratfink:
There seems to be an issue with your kernel ignoring the limitations set by SetCPU. I have used the kernel and it works great but even if i set my max clock speed to 1Ghz it will go up to 1.53Ghz regardless. Can you please address this bug, thank you
[Desire HD Android Development] RD1945:
Disable perflock and see what happens. Worked for me (tried it 2 seconds ago).
[Desire HD Android Development] bratfink:
Yup previously overclocked my SGS so never had the need to use this feature, thanks alot for pointing it out. Maybe OP should list this in the 1st post so people know.

Feel so stupid forgetting this setting in set cpu :( now when i disable perflock i can set my cpu to exactly what i want, now its perfect ;)
