Exciting times mate :P

Looking forward for a V5f Battfix(yours) with these improvments!

Thanks for all your efforts!
[Desire Android Development] sibere:
Here is a V5e with the new revolutionary GROUP CPU scheduler. I just booted my phone with it and , at least, it's working. ;)

Let me know if you feel any improvement!

see my thread (http://xdaforums.com/showpost.php?p=9280769&postcount=58 ) for that. I don't want to mess-up with richard's thread :D

great stuff Richard. Will we have GPU tweak? Thank you for this great kernel.
[Desire Android Development] d3sm0nd:
Works fine for me on Auaxtsense 7.8.1... no idea why the some people have problems.

The only thing is that I don't have powersave and interactive mode in SetCPU anymore...

But so far my ROM works even better at stock frequency with this kernel... I just hope it will not drain battery faster than other kernels. :)

Thanks

i get around 1300-1400 with the default kernel of my rom...but i want to test this too but i have a question

i use the screenstate script to set my cpu governor when screen on and off...and cpu frequency too. can i make the same with the overclocked frequency 1113mhz ???

i don't like setcpu that's why

also are the modules in /system/lib/modules working with this version ????

YES!!! Thanks!

I'll post quadrant results :)

[Desire Android Development] sibere:
You shouldn't get extra CPU power with that. But you should feel more responsiveness from you Desire.
[Desire Android Development] Zeljko1234:
After your post, I flashed v5e and tested till now. I don't see any differences, everything is smooth.
[Desire Android Development] yukkio:
I've seen bechmark's results with this scheduled and people gets 200 extra points on quadrant :)

Edit: Got same result on quadrant. I think I need active the new scheduled. In linux: echo 1 > /proc.../sched_autogroup_enabled
[Desire Android Development] sibere:
WOW amazing! I don't see any difference so far. Can you post a link?
[Desire Android Development] yukkio:
Sure, here's: http://pastebin.com/hS8EScDV

Nevermind, that guy got more linpack score but my linpack's score it's the same too... How can we know if the scheduled is enabled?

Edit: A contact with a n1 with that hack get 250 extra points in quadrant that the same rom without the hack

nop! Sorry but my forked kernel is with undervolt and batt fix. If you just want the new cpu scheduler, ask richard. I'm pretty sure that he'll be very happy to patch his kernel with it :)
[Desire Android Development] dj-darkside:
Ok Thanks.
[Desire Android Development] yukkio:
I don't know if the module's name or location is the same, but that's module's name in the linux kernel.
[Desire Android Development] sibere:
dunno.

Maybe because I had to disable the "cpuset" option, it was causing compilation crash

but there's cgroups in /proc

[Desire Android Development] Johannn90:
hi,

i am new on this forum. so maybe my questions are sometimes quite strange!

My question is, what is exactly the audiomod??

I have just downloaden Froyo Kernel V5f 1113Mhz max and it works fine! (on my desire with PAYS rom and the newest radio).

Is the best CPUspeed 1113 MHz? Or is 998MHZ better for a longer battery standby?
[Desire Android Development] yukkio:
Ok, there're cgroups but Is there any way to confirm If we've that scheduled enabled like in linux (cat /proc/....)? "1" enabled "0" disabled.

Also, has your kernel gpu+?

BR.
[Desire Android Development] sibere:
See http://xdaforums.com/showpost.php?p=9242934&postcount=16 for all infos
[Desire Android Development] sibere:
really dunno. What options did you use to build your kernel?

If you didn't, could you give me /proc/config.gz ?
[Desire Android Development] yukkio:
I think there's a confusion, I'm installed your kernel not mine :P

Edit: we could ask for help on n1 forum to compile the kernel with the patch.
[Desire Android Development] sibere:
Yes there was a confusion :)

Where did you get the info for the /proc thing ? I would like to have a look :)

Have a look at the battfix thread. I think that there's one kernel there with gcs
[Desire Android Development] Anakha56:
I am going to ask a stupid question but hey its the only way a person learns :).

For someone who is new to the whole kernel flashing department which of those 4 should be the first to try? And whats the difference between the HAVS and non HAVS?
[Desire Android Development] CerB:
very very stupid allegation, if you wanna learn, then read the thread !!!!!!!!
[Desire Android Development] Anakha56:
Allegation? :confused: Dude I did not allege a thing just asking a question. Take some chill pills and go play with yourself in the corner you seem to be tense...

/So much for a friendly neighborhood I see XDA is starting to lose that quality...
[Desire Android Development] aslsthlm:
Want to know to ?
[Desire Android Development] Anakha56:
Well I have worked out so far that the last 2 are mainly for overclocks to get faster speeds. I dont think that would work to well in the area I live due to heat. What I am now trying to workout is:

The difference between these 2? Is it just a lower voltage? What would the benefit be to run the lower voltage one? Better battery life?

Thanks for the reply much more appreciated than a certain someone else...
[Desire Android Development] TheGhost1233:
Depends on what you want, if you want to over clock a lot use 1190Mhz(might not be stable)

If battery is imported use on of the undervolted kernels (start with 925mV min because 875mV might not be stable)

And if you absolutely have no clue use 1113Mhz.

The HAVS and non HAVS is easy to find (even in this thread) and the fact that you can't find/not willing to find it, is also an example of the lose of quality.

See almost same post with answers: http://xdaforums.com/showpost.php?p=9276410&postcount=960
[Desire Android Development] Anakha56:
Actually I am on page 59 post 581 made on the 281010 by tomurbanowicz ;). Hence the reason why I found out that the higher clocked ones for overclocking purposes. I did a Google search for HAVS and to my surprise I received a lot of hits for:

So yeah I did not search hard enough... :rolleyes:

But thank you so much for your response it is greatly appreciated.
[Desire Android Development] LuffyPSP:
which one is the closest to stock? and better in performance?
[Desire Android Development] WindBurner:
Big thanks!

Thanks for answering. Gonna try it out. :cool:
[Desire Android Development] Large Hadron:
For the 2 HAVS kernels I believe the difference is lower minimum voltage. As I recall HAVS will lower voltage according to temperature and cpu speed, while the others (SVS) just have a fixed voltage per clock speed.

If the lower voltage works for you then it should, as you say, give better battery life. However, due to manufacturing variations not all handsets will be stable with the lowest voltages.

If in doubt, try them all (or all that interest you - I've no need for 1190, for example) and see what works best for you.
[Desire Android Development] anko184:
Could someone please add the GCS patch to "Froyo Kernel V5f_HAVS@875mV min No Audiomod version".

[Desire Android Development] lept0n:
Hi Sibere

I have flashed your patched kernel with the gcfq patch, how to check if its activated and working. Thanks.
[Desire Android Development] sibere:
Honestly I dunno... I just patched the sources with the last Gcfq patch. The patching process terminated with no errors so I guess That the full patch is applied.

Then I selected the new groups scheduler and many other options before compiling the kernel. It's there by default now.

Before the patch , my phone was a bit laggy when it was at 128MHz and specially when coming out of sleep.

Now everything is smooth :)
[Desire Android Development] superfurryallan:
Hi Siebre,

if i use your 875mV or 925mV HAVS patched richardtrip kernels with the Bat Fix and GCS on my desire, i cannot successfully boot, However the SAVS kernel works perfectly........

Im a little confused as coutts 875mV Leedroid BFS kernel works fine on my desire.

Im running auraxtsense 8. I thought it was perhaps related to voltages on my desire, but the fact that couts 875mV HAVS works would suggest that perhaps this isnt the case.......

Im keen to use the GCS as I too have a much smoother experience than with BFS. But im also keen to prolong battery life, and i believe HAVS should be better at this.

Can you help?
[Desire Android Development] lept0n:
Hi Sibere,

Regarding the GCS user exp, i was following the thread by coutts99 and it mentions that this does not make any difference in performance. Please check it out and let me know you thoughts about it. thanks.
[Desire Android Development] superfurryallan:
I have to be honest. I am unsure of the fundamental differences between CFS, BFS and GCS. For the last 24 hours have been using Sibere's GCS kernel and it is very smooth at lower cpu frequencies.

Scrolling is very smooth, and the touch screen is very responsive. From what I see, i think other peoples reasons for not including GCS is that it does not give significant increase in quadrant scores.

Also coutts recently posted this in response to my post on his kernel regarding adding GCS.........

'No, I can't get the patch applied easily, not sure now sibere did it, all the patches I can find require backporting.

I also doubt it makes any difference so am stopping with Bfs.'
[Desire Android Development] sibere:
IMHO you won't get a CPU score boost with GCS. this patch is for interactivity, not CPU optimization.

I honestly don't remember how I did apply the patch and I'm getting suspicious about it. I'm starting to think that it applied partially. But still, I can feel a difference with CFS.

I've tried with and without GCS patch. @128MHz when the phone is turned on and I unlock the screen, it's smooth with the patch and laggy without. And I'm not the only one who felt that. I can't give any explanation, it's just a fact.

ATM I've patched my (richardtrip) kernel with cyanogen backport but the compilation fails...
[Desire Android Development] superfurryallan:
I can certainly confirm the smoothness of the lock screen at 128MHz and smoothness of the scrolling.

My only problem is that I cant get any of sibere's HAVS kernels running on my phone :( I have to use the SVS one. Yet coutts BFS HAVS 875mV and 925mV both work fine on my phone.

Ideally i'd love to get a 875mV HAVS GCS kernel working on mine, for the responsiveness and increased battery life :)
[Desire Android Development] sibere:
Do you have app2SD? Did you try to download one of my builds with ext2/3/4 enabled? This could solve the boot issue.
[Desire Android Development] superfurryallan:
Yes I have app2SD.

I tried both

Kernel_Froyo_V5e_havs@925mV_BattFix_GCS.zip

and

Kernel_Froyo_V5e_HAVS@875_BattFix_GCS.zip

The first occasionally boots then freezes, and goes back to the nexus flash screen

The second always freezes on the nexus flash screen.

Kernel_Froyo_V5e_SVS_BattFix_GCS.zip works perfectly.

Are there different HAVS versions I should be trying?

Thanks for your help.

Allan
[Desire Android Development] sibere:
Maybe the voltages I use for intermediate freqs are too low for your phone.

Be aware that the SVS is undervolted also :)
[Desire Android Development] superfurryallan:
where would i find a list of the voltages you use for the 875mV and 925mV kernels?

Could I change them to the voltages in coutts leedroid kernel?

couttstech-2.6.32.26_LeeDroidv2.2f_HAVS@875mV_CMBattFix_BFS_BFQ

as this works fine also, but is laggy compared the the GCS kernel.

Appologies i'm new at the kernels :) Began to understand ROMS, then radios, and now kernels. just trying to squeeze the most out of my phone :)

I did also have problems with neophytes v20 kernel. Which despite numerous good review, would not allow my phone to boot at all :(
[Desire Android Development] superfurryallan:
Even stranger...... I have now installed, and successfully booted to your 850mV HAVS kernel with GCS.

I'll wait and see how stable this is for me.....
[Desire Android Development] coutts99:
Patch backport here if you are interested -:

http://mirror.couttstech.com/android/bravo/kernel/taskgroup-2.6.38-backport-2.6.32.patch

I'm just trying it now
[Desire Android Development] superfurryallan:
As I mentioned, I installed the 850mV kernel and it seems to be working perfectly for me. Still very smooth.

I ran the following at the request of coutts, and got the following

C:\android-sdk-windows\tools>adb shell

* daemon not running. starting it now *

* daemon started successfully *

# cat /proc/sys/kernel/sched_autogroup_enabled

cat /proc/sys/kernel/sched_autogroup_enabled

/proc/sys/kernel/sched_autogroup_enabled: No such file or directory

which coutts has said mean that autogroup is not enabled.

So im really not sure of the reasons behind the responsiveness of this kernel. But responsive it is.
[Desire Android Development] dinaroga:
got a bootloop trying this on teppics stock rom :(
[Desire Android Development] sibere:
I do confirm that autogroups is not enabled, just Cgroups. This why I really don't know what happened during the patching process 'coz I ended-up with a snappier kernel anyway.
[Desire Android Development] Scray:
hi,

have you implemented something like "volume long press" to skip music track, as you did in your cyanogenmod kernel? i would be very glad if someone could tell me whether there is a Sense or a MIUI kernel/ROM with this feature.

I have tried every sense kernel on the market. Nothing over 1113 works and the v5f kernel scores less on the quadrant but performed way better for all apps Inc high output games...

Scores 1450-1550

Others score 1600+ but lag alot. Guess quardrant is a load of bull.

:)
[Desire Android Development] yeahimdukenukem:
I have a noob question, too:

I rooted my Desire yesterday, but not installed any custom rom, only the ClockWork recovery.

May I use that custom kernel and do I have benefits or do I have to install a custom rom first?

Thanks alot for your answers
[Desire Android Development] iemand12:
You may use this kernel with your stock rom, just make sure you're running froyo, there are benefits, more performance and better battery life ;)
[Desire Android Development] yeahimdukenukem:
Ok, great, thanks for your answer. :)

Now I'm asking me, which of these packages I should use. I wanna have more battery life, but also performance when needed. So I think the best would be the

Froyo Kernel V5f_HAVS@925mV min

Is that right?
[Desire Android Development] sibere:
Good choice, maybe you should choose the noaudiomod though
[Desire Android Development] yeahimdukenukem:
Why that?

I thought, this would improve the audio output. Am I wrong?

What does it do exactly?
[Desire Android Development] sibere:
Many users reported issues and no audio improvement.

YMMV tho
[Desire Android Development] bg_man:
Same for me.

No audio improvement at all.

Sorry I don't know, but I would also like some clues on what to do next.
[Desire Android Development] st0kes:
Hi, by the way I got my kernel to build. I had some missing packages. Try getting these in case any are missing:

sudo apt-get install git-core gnupg flex bison gperf libsdl-dev libesd0-dev libwxgtk2.6-dev build-essential zip curl libncurses5-dev zlib1g-dev

I am using Ubuntu by the way.
[Desire Android Development] Azurael:
Dunno... I used to get around 14-1500 with this kernel under AuraxtSense... Now, under RCMixHD, I get 16-1700 with the same overclock, governor, etc... So kernel is not the only deciding factor... Plus, results seem to vary wildly from run to run. The only thing that seems genuinely consistent about Quadrant is that the second run always seems to be significantly (1-200 points) faster than the first. I'm now outbenching my gf's stock Desire Z in Quadrant despite the Desire's GPU fail vs. the Z & HD :rolleyes:
[Desire Android Development] Dragooon123:
Hey, uh, if you don't mind. Can you increase the clockspeed of s5k3e2fx to 83Mhz? I have noticed that it actually increases FPS(I was able to sustain ~23FPS while recording TV in bad light) in other kernels. That, or if you can tell me how to compile the kernel in Linux.

http://review.cyanogenmod.com/#change,35
[Desire Android Development] Dragooon123:
OK, I managed to compile the new kernel with the changes and I have really noticed a significant difference. It managed to record a video playing on my monitor on a totally black room with an average FPS of 19, whereas it used to be in the ranges of 10-11. I'll do some daylight testing but so far it has been good.
[Desire Android Development] Zeljko1234:
I don't understand, of what speed is increased to 83MHz? Could you share your kernel with us?
[Desire Android Development] anderl78:
For the s5k3e2fx, i think its this:

http://www.samsung.com/global/business/semiconductor/productInfo.do?fmly_id=220&partnum=S5K3E2F

Or am i wrong?
[Desire Android Development] Dragooon123:
Yes, its the camera chip which has a default clockspeed on Desire/N1 of 80Mhz, increasing it to 83Mhz gives a boost in FPS(The change might not be so prominent(Its only 3Mhz afterall) but it works wonders). I've attached the kernel I built, I do NOT recommend using this kernel because I built it :P. I'm very new to kernels and know hardly anything, I built this with the config of my Desire running the HAVS(113Mhz max) version, I'm not exactly sure what all is enabled/disabled in this version but I chose the default options.
[Desire Android Development] knights191:
Besides setting it on 83 mhz, is it possible to overclock this chip ? :P
[Desire Android Development] horst0815:
i was using the supervillain hd rom for 3-4 days now, and yesterday, i flashed Froyo Kernel V5f_HAVS@925mV min No Audiomod version this, and it works even better than the standard kernel from the hd rom. but now i encounter wifi breaks. i have to disable and enable wifi manually to get it working again. is this problem kernel related? i didn't change any of the option, or install some bogus app. just flashed the kernel.
[Desire Android Development] paolo.mactux:
wow!! :D

great man!
[Desire Android Development] IVS IVRIS:
Just flashed this kernel.. seems stable to be. Quadrant score just got around 300+ (almost 1500) higher. This on Sense stock rom, just rooted.
[Desire Android Development] melethron:
Don't know if this is already a known bug but HAVS can't set the 1300mV@1113mhz.

dmesg:

<3>[ 310.378173] AVS: Voltage can not get high enough!

Coutts99 uses the same code in his Kernel as RT and this issue is also present. Since his Kernel has 1190 max OC i set it to 1152 and after that HAVS could set 1300mV@1113 but the message still occured. So i think there is an issue setting highest mV for the highest clock speed.
[Desire Android Development] coutts99:
Clock speed were out by one, e.g setting OC to 1152 in setcpu was only overclocking to 1113

http://bit.ly/hTKBJ9

That diff fixes this issue.
