Wifi signal significantly weaker with intermittent drops 4.2 CFS CM7 Nightly #42

Reflashed 4.1 CFS with CM7 Nightly #42 to test if CM7 #42 was the issue, no drops and improved signal.
[Desire HD Android Development] marshy73:
Using CFS PUV. So far so good.
[Desire HD Android Development] justin0307:
Using 4.2 CFS UUV now no freezes or reboots.

Tried PUV, but stuck in the htc white screen. Wish it works on my phone :(
[Desire HD Android Development] Tantin:
I can't go below -25mV so yeah, you're actually quite lucky. ;)
[Desire HD Android Development] LorD ClockaN:
Yeah, I know that there isn't very big difference, but there are a lot of people here and I want to make it as stable as possible...

My next kernels will have default min freq at 230 for stability, but it can be possible to set at 122MHz

My next project will be to make 3*2 versions of kernel for 3 different I/O schedulers and than provide scripts for lowering voltages...

But don't know if I'll do it before Easter...

And if my wife lets me :eek:

edit:

@justin:

have you tried downloading PUV 230MHz version from few pages back?

Please do and report back...

@tantin:

maybe the problem for you is default of 122 MHz for min freq.. so wait for the next release.. will have 230 for MIN freq
[Desire HD Android Development] Tantin:
Well, for the UUV or -50mV Versions I can actually enter my PIN and the it freezes. So I guess it's the voltage not the clock speed. But I'll try anyways. ;)
[Desire HD Android Development] sms_chu:
HA HA HA!

4.2 CIF PUV, works for over 12 hours moderate use, no single issue! Seems that my DHD doesn't mind low voltage at all! :D

P.S. Still has 70% juice left!;)
[Desire HD Android Development] LorD ClockaN:
LOL

It's CFS, not CIF :)
[Desire HD Android Development] sms_chu:
Too happy;)

All games like the kernel too.
[Desire HD Android Development] LorD ClockaN:
OK guys..

uploaded new versionssss

nothing new except you get to experiment with different I/O schedulers..

Please give feedback which is the best..

and don't forget to use VDD scripts and modify them as you like!

Let the force be with you :)
[Desire HD Android Development] jerrylzy:
122 puv works fine! Thanks very much..

And is V(R)/IO got the best performance?
[Desire HD Android Development] LorD ClockaN:
Don't know..

I was last few days on VR and it lookd great!

Now I've flashed BFQhs and it also works great.. for now.. who knows what I0ll flash next. :)

Don't think there are any BIG differences..

But I like BFS more than CFS, but most of folks here don't like BFS, so I've uploaded all versions..

test and report so others will know
[Desire HD Android Development] jerrylzy:
Which place is your DHD made in? HT or SH?HT may have better quality..
[Desire HD Android Development] jerrylzy:
Yes,It seems that BFS has more issues than CFS..I always use your CFS edition. It works very fine..Great work...Thanks!:D
[Desire HD Android Development] arash64a:
Can any1 post a direct link for latest CFS kernel please, i cant download from multiupload.

Thanks

hi can u tell me a good kerne bec im noob at this kerne , im using cleanhd 1.20 , and want a fast really fast one. thx:confused:
[Desire HD Android Development] io53:
I LOVE that you have different versions of your kernel so that you can try them out and see what fits best :)

Thank you!
[Desire HD Android Development] jpinky:
4.3 is feeling good - running my usual custom vdd scripts and its solid so far.

nice one !
[Desire HD Android Development] Ratix0:
Thanks! I tried UUV today, somehow, it ran without any errors or anything, but performance wise suffers a noticable amounts of lag for some reason. I guess my DHD can't run UUV properly... I flashed the non UVed Kernel and everything is smooth as a flash! =D. Really great! Maybe I should experiment with the -25 and -50mv kernels.
[Desire HD Android Development] helushune:
Cheers for the fantastic kernel. Just flashed 4.3 BFQhs with the -25 undervolt and it runs smooth as butter.
[Desire HD Android Development] Ratix0:
Quick Question, in 4.3 right now, I gotta flash the first set of kernel after which I flash the -25/-50 or uuv scripts?

Meaning they are no longer standalones?

Also

Any noob friendly description of the difference between BFQ, BFQ with HS, Simple I/O and VR I/O schedulers? Whats the main difference and what impact would an average user see with the different schedulers?
[Desire HD Android Development] LorD ClockaN:
Yes. Fash, boot, flash script

@iraqsniper:

If it's based on cyanogen cm7 than it will work.. backup before

Anyone who could run PUV kernel before without issues should be able to lower 230500 and 307200 to 750mv and 768000 to 875 and 844800 to 900. I running thes stable with stress test at each stepping no errors.

@Lord Clockan, Stepping 1152000 is set at 1020 which will revert to 1000.

Getting 1mv when screen off wifi and sync on, great work Lord Clockan!

Using cleanhd there are many many lags and freezes with this kernel (if you use under voltage edition).

Edit. this comment is based on my experience with cleanhd. Now i use cm7 nightly42 and there are no issue.
[Desire HD Android Development] henrybravo:
So you are saying the problem was with the ROM, not the kernel? Or are you now using the stock kernel on CM7 nightly 42?
[Desire HD Android Development] razor 116:
@Lord Cloackan

The mv setting for stepping 1152000 is set to 1020 in PUV script it will revert to 1000 when used.
[Desire HD Android Development] LorD ClockaN:
I've noticed some poor mobile signal with PUV script, so I've reuploaded puv script with modified firs 4 basic freq volateges and it seams so far so good

Maybe cleandhd isn't configured to use newest adreno 205 drivers that this kernel has
[Desire HD Android Development] LorD ClockaN:
sorry.. should be 1025...

I'll reupload it..

but if it can suffer 1000mv, that is 25mv lower than thats great news :)
[Desire HD Android Development] zerocool87:
now i'm using full rom cm nightly 42. I did not tried to install only the kernel.
[Desire HD Android Development] Neoman:
lordmodV4.3-BFS-BFQ gives the best performance, but wifi doesn't work with this kernel, please check. I'm using CM7 final.
[Desire HD Android Development] LorD ClockaN:
Have you tried to reboot after kernel flash??
[Desire HD Android Development] Neoman:
yes, i have rebooted my phone after flash, it still gave me an error. I also flashed all other kernels which have no problem with wifi.
[Desire HD Android Development] LorD ClockaN:
now you tell me :)

I just compiled and uploaded bfs bfq again...

Well than there must be some other thing in the game

try clearing cache, dalvik, fix permissions..

try to manualy copy bcm4329.ko from .zip files to /system/lib/modules and give it executable permissions.. all wit root explorer or adb
[Desire HD Android Development] Neoman:
The reuploaded version works fine, thank you. It seems something was wrong in the previous version.
[Desire HD Android Development] LorD ClockaN:
Maybe I included the wrong wlan module, but there were 30 downloads and no one reported bad wlan

great that it works for you!!!
[Desire HD Android Development] fidorulz:
Thanks for all the work but don't know which one to choose now lol
[Desire HD Android Development] LorD ClockaN:
no ****!?!? LOL

must collect them all!!
[Desire HD Android Development] vatranxxx:
+1 :)

But wifi works fine here.

Since i changed the ROM from cleandhd to cm nightly the kernel works perfect. Im on nightly #51 with bfs bfq uuv because i have random reboots with puv! ;)

Thx for the great kernel.
[Desire HD Android Development] Freakgs:
Same wifi problem

Screw my post, after the 100th wipe Wifi is working perfectly fine now.

Thanks for your great work!
[Desire HD Android Development] imptb:
Flash the kernel then flash the PUV?
[Desire HD Android Development] justin0307:
EDIT: Oh I'm sorry I think it's different for 4.3 now. I think you do need to flash either CFS or BFS, then flash the script. Correct me if I am wrong thanks!
[Desire HD Android Development] justin0307:
Thanks for the reply lord, I will give it a try after I fix my GPS. Somehow my GPS doesn't work anymore :(

volume tweak

Hi,

I'm running cm7 rc4 at the moment.

2 questions about your first post :

- "Volume boost 10%". Exactly how do you do that? Is that a setting somewhere?

- "Battery drain fix included" : Any more info on this? Will it also be included upstream in cm7?

Thanks

Steven
[Desire HD Android Development] Iachimo:
The volume boost is a kernel thing. Not a setting you can change yourself (besides using the buildin dsp manager)

The battery drain fix is just mentioned for reassuring ppl that it is also included in this build. Its been in cm7 since build 29 i think. Also present in your rc4 ATM.
[Desire HD Android Development] htctouchelfin:
Great Kernel!! cyano rc4 1,92 no freeze

So would using this kernel with standard clock help save battery life with smartass gov? Not a fan of overclocking but smartass seemed to save battery life on sense roms in comparison to ondemand gov.
[Desire HD Android Development] LorD ClockaN:
CM7 has Interactive governor that works great.. Smartass is a little improved version of Interactive governor..

Ondemand governor isn't very battery loving.. It uses only min and max freq. interactive and smartass uses all the frequencies in between..

I'll add more frequencies to the new version of kernel soon, so the scaling will be more fluid
[Desire HD Android Development] da blitz:
:):):):) is possible?
[Desire HD Android Development] LorD ClockaN:
yes it's possible, but it seemd that there has been some issues with volume that high so every developer reduced to 10%.. maybe I can try and set it to 15% just for test...

DO you use DSP application that came with cm7 and boost volume via equalizer??
[Desire HD Android Development] tids2k:
very good and fast rom, you are heading in the right direction . :)
[Desire HD Android Development] da blitz:
yes i use it,but if you try a sense rom,volume is more higher than cm7

[Desire HD Android Development] EvoXOhio:
Unless I am missing it somewhere, can someone do a wirte up on all the different 4.3 kernel version and what they all mean? I read up on Cfs versus bfs for 4.2, and chose Cfs. But now with all the other new options I am utterly confused.

I would love to see some explanation of each kernel/option, as well as a reason why to pick one over the other (example: pick bfs for quadrant scores but there may be one UI lag, pick Cfs for less lag and improved multitasking, etc.)

Thanks

which scheduler you want?

https://dl.dropbox.com/s/1os9u9b3q10vnd4/lordmodV4.3-CFS-BFQhs.zip?dl=1
[Desire HD Android Development] justin0307:
hey lord,

It works when I use the PUV script from the first post. However, if I ever change the min from 230 to 122, my phone will freeze.
[Desire HD Android Development] tmt64:
4.3 BFQ CFS -25mV caused random freezes on CM7 stable on my inspire. After replacing the battery, i got stuck with a black screen right after lockscreen loads.
[Desire HD Android Development] LorD ClockaN:
Thats why I've set min freq by default to be 230 because of stability.. and some phones can take 122, some can't..

no worry, use 230 min

@tmt64:

looks like you phone can take only a little under voltage that comes with the normal version, but can't take any more :(
[Desire HD Android Development] LorD ClockaN:
Wll If I knew which one is better, I'll use only one..

Try all 4 of them and see which one is better.. report back and that's the way I can develop and upgrade only one or two versions that come up superior than others... this way I try to help people find the best suiting scheduler for their needs..

Someone posted few pages back a benchmark result link and VR scheduler was the fastest, but that doesn't mean that is faster in real life expirience..

I had all 3 of schedulers and now using BFQhs for a day because never tried that one... that doesn't mean I won't try another one...

BTW.. when you change kernels, you don't need to apply the voltage script again.. and it's not a ROM and will lose some data... Backup just in case and FLASH ON!
[Desire HD Android Development] justin0307:
Okay I will stick with PUV for some time and report back. :D
[Desire HD Android Development] tmt64:
I see.. I will stick with the default CM7 kernel and flash yours once you decide on which scheduler to stick with. :)
[Desire HD Android Development] LorD ClockaN:
LOL...

Default cm7 kernel has BFQ scheduler..

I give you the oportunity to try others.. If you don't like them, use BFQ
[Desire HD Android Development] justin0307:
Aww now I am getting freezes and need to pull out the battery to reboot every time. :( And once I reboot, it will freeze again. :( Maybe my phone cannot handle PUV...
[Desire HD Android Development] LorD ClockaN:
Maybe it needs just a little more voltage..

Use UUV script or just modify PUV script by rising all voltages to 1500 by 25

is this like 4.2 where u pick 1 and flash it or do u pick (BFQ - CFS - BFS reuploaded BFQhs - CFS SIO - CFS - BFS VIO - CFS - BFS) AND (-25mV zip

-50mV zip UUV zip)
[Desire HD Android Development] LorD ClockaN:
You pick if you want CFS or BFS, than which scheduler, than the script for voltage
[Desire HD Android Development] Mr_JMM:
I tried to flash 4.2 CFS via Kernel Manager App yesterday and had some strange issues.

The app said the kernel was installed but under About Phone it still showed Cyanogenmod standard kernel but I also lost wifi. Just got "error" under wifi option.

I didn't say anything until now as I wanted to find out problem first. Did a few resets and reboots but they didn't fix it. Did a NAND restore and all ok again. However it looks like you may have fixed the issue in 4.3 so will try again.

Has anyone else tried via the Kernel Manager App?

Thanks LorD C. Just as I read your reply I noticed an update for the KM app that does indeed correct flashing issues.

I will have another stab at 4.2 just out of curiosity to see if the Kernel Manager does work and if that goes ok will manually flash to 4.3.

[Desire HD Android Development] jpinky:
Just a quick note to all UV'ers on this thread, test your settings unplugged from charger (and USB)

It seems like some degree of extra stability can be 'faked' by the system when it's on charge, possibly it is supplied a more stable or slightly higher voltage while plugged.

Noob-ish q: how do you modify the scripts for voltage? Just use notepad to edit the 99voltage file, save it, and re-zip it, right?

Yep, but edit it while still in zip...

Or zip it with 7zip application and edit with notepad++ if you aren't in linux

What's a safe version of 4.3 to run if I'm on Inspire 4G with CM7? Do you guys run Neocore or Test CPU to see if a certain setting is stable before checking setboot? Thx
[Desire HD Android Development] jpinky:
I've used neocore before but I don't really like it for stress testing it's a bit too gfx centric. When I've had stability issues, it generally hasn't been in graphical use it's been in general stuff.

From what I understand the CPU over or under clock/volt affects the GPU as well on the snap/scorpion/adreno chipset

Generally I run up the stress test in setCPU for a while and then run the quadrant bench and as a final test for more of the generic use (non-gfx) I run up smartbench 2011.

99% of the time an unstable volt will crash immediately on hitting the frequency you're tuning.
[Desire HD Android Development] asphaltkiller:
it s maybe a dumb question as I have read all pages of this thread but I haven t found a way to edit voltages as an "user interface" than editing manually the 99voltages file in the zip??

Is there a way to do it in android??

EDIT: and how to check if correct voltage have been applied?

thks

Ok nevermind it's easier than I thought...thks

EDIT3: wtf no I haven't get it.... do i have to manually edit the vdd_levels file located in sys/.........cpu0/ ???? everytime I edit it and re-open it the values are the same....

or launch it as a script... i'm totally lost for the first time in 2 years of android tweaking ! nice!

[Desire HD Android Development] gordec:
Guys, I'm not a Linux expert, just wondering what's the whole reasoning behind OC/UV to achieve better performance? Ok it makes sense by increasing the CPU speed and lower the voltage to get better performance but improves battery, but why isn't stock ROMs like CM7 and others utilize that after finding the most stable OC/UV setting.

I'm really interested in trying out the CFS BFQhs kernels but have no idea if I should go with -50, -25 or UUV to go with it. I read through significant portions of the threads.
