Blechd0se, you have included some interesting new commits, any change in the phone behaviour as a consequence? :)

With 20/12 again no network with quarx 05/12 [Defy+], can someone confirm?

[Defy Android Development] super noob bros:
+1, the same thing happens with quarx's kernel with latest commits as well.
[Defy Android Development] ithakaner:
+1 same situation here ...retuned to 13/12 CFS

I had as well the problem with the 100% back-light for the menu buttons...

in general I had with all Blechd0se-Kernels a problem with the sound: outputs (!not music playing) are starting delayed and scattered the first seconds. Not too bad since they are played but kind of disturbing.

I don't know how you phone is behaving, but now with this kernel I get a quite good performance, Gov: Interactive and I/O: Sio

Sometime lags, might be due high app fluctuation sometimes up to 200 apps, anyone knows a good kernel config for that purpose?
[Defy Android Development] esok44:
Hey guys,, so im getting this right, 20/12 isnt Working properly. So in should stick with? 13/12 ;)
[Defy Android Development] Feche:
My phone has random freezes with this kernel.. (12/12)
[Defy Android Development] esok44:
In which rom? If you are in 5/12 try 13/12 With interactive Gouverneur. Works great for me
[Defy Android Development] Blechd0se:
I uploaded a new build (bfs-version will come, when the build is finished :) )

It mainly has fixes for the new nightly from quarx (22.12) but also some new features. I hope those reboots are now gone and can somebody please test performance with CFQ-scheduler? I backported it from 2.6.33, because of the new Block IO Controller. Oh and it contains a commit from quarx which gives you a little more ram (~3mb), thanks to him :)

Why is this build only working with 22.12?

Because Quarx disabled the trace support again (a bit frustrating for a kernel developer...). Long story short, 22.12 will work only with the nighltys from 22.12, however you could try a build from 5.12 it should also work with those new nightly from Quarx.

Can anyone test latest kernel with slimbean from Kayant? Not at home right now. Thanks.
[Defy Android Development] ldiomedi:
I'm using Kayant's PAC rom, and it's working fine (just 30 mins of use). The lastest kernels dosent wwork on this rom, i think because the trace support, but this one booted! since SB its from almost the same time of PAC, this lastest kernel should work too.

For the record, I notice my phone a little more responssive and a little faster. Savagezen gobernor and cfq I/O. Lets see how it goes in time.

Nice to see you don't give up, Blechd0se. Thanks!!
[Defy Android Development] sebx_g1:
On slimbean 3.1.2 (not want Kayant one), this kernel boots but there is no networks - no GSM network and WiFi.?
[Defy Android Development] Blechd0se:
If you have no network its because of this trace thing. if your rom dev didn't update the build and used another base (except the 22.12) you should try a older kernel.
[Defy Android Development] Alka-Seltzer PLUS:
@Blechd0se

Thanks in advance for your work.

I am unable to boot the ROM ( last Quarx's build at the time of writing, 20121222, clean install ), I flashed the " kernel_22.12-cfs.zip " and then I rebooted as I did ( with success ) on the MotoIceGun edition ( which booted but I got no networks at all ): did I dismiss anything to set in bootmenu after having flashed the kernel and before booting the ROM again ?

Have a nice day,

Alka
[Defy Android Development] Blechd0se:
The last kernel should work with the latest quarx build. Did you flashed the kernel directly after the installation of the rom?

You should boot your phone at least one time up with the default kernel and then flash jellyx...

About the MotoIceGun-Rom i don't know which base it uses. The only thing you have to set in bootmenu is 2nd-boot, but

it should do it automatically.
[Defy Android Development] Alka-Seltzer PLUS:
I did the steps as you mentioned, booting up. the phone once and setting it up a little bit and at first reboot flashing the kernel and rebooting again: bootloop.

So i cleaned cache and dalvik and flashed the ROM over and it booted again.

As soon as possibile i will provide some logs :)
[Defy Android Development] esok44:
Blechdose, you saved my christmas :D

Was going to have a long trip to Hamburg for christmas Holidays, and wanted to watch videos on my mobile...

With QKernel playback was laggy as hell, but with JellyX everything is freaking great :D

Thanks a lot dude. It would love to donate to you, but i dont have paypal, maybe you could tell me in a PM, how i could do it on an other way.

Thanks a lot dude, you are awesome :D:D
[Defy Android Development] niksy+:
Flashed the yesterday's JellyX together with yesterday's CM10 (at the same time, without booting with Quarx's kernel) and it's working completely stable :)

Currently using savagedZen + deadline... Is cfq the recommended scheduler now, Blechd0se? Or are you just interested in its performance since you've updated it?
[Defy Android Development] no_means_no:
No signal with latest kernel over Kayant's latest SB. Went back to kernel from 12/13, signal is back!

Which Kernels to Flash on Quarks 22.12 CFS Or BFS

I know few peoples say that its silly question :p

Just want to know which kernel we should flash on Quarks latest 20121222 Build ???

Thanks in Advance,

Avi Tandel
[Defy Android Development] zakoo2:
oh my god... this is not a silly question, but a really stupid one...

this is a forum... do you know what a forum is? no, its not a hotline, people here are not for your help. this is something like a knowledge database, where you have to SEARCH before asking questions and posting... just read 1 freakin page back, where the OP and developer of this kernel stated that the new kernel is for quarxs 20121222 nightly...

i dont care if youre new to this forum or not, you shouldve read the terms of usage...

please, mods, clean up the mess around here!!!
[Defy Android Development] Aslolo:
Cool down mate, totally understand you, but noobs stay noobs, even if you shout at them...
[Defy Android Development] ldiomedi:
Have to said its not just for latest quarx build. I'm using PAC rom from 11/28 and the kernel its working very good. Couldn't measure the battery, but I'm having a very good life for it. I believe this kernel may not work on all the December's roms, but on previous it should. tested almost all the governors and the best for me is scary.

The thanks button doesn't bite. Try it!
[Defy Android Development] Alka-Seltzer PLUS:

[Defy Android Development] niksy+:
Try switching the governor to interactive. And try to turn off zRam. Any improvements in stability?

Don't have other ideas... Running perfectly fine here, no restarts after ~18 hours. I am on the yesterday's CM10, but looking at Quarx's commits... I see nothing that could have broken the compatibility :rolleyes:

i always change setting in bootmenu only ......

i diabled zram only ksm , and back to sio and interactive , ......1100@55 .......

rebooted

back to savagedZen governor + zen scheduler and zram 18% and default cpu settings , will test for day , and will report again on this if this is stable ,

and will be looking forward for a solution ......

thanks for kernel .....

[Defy Android Development] tronjojo:
Thanks to everyone for the great work on the Defy.

I'm on latest quarx cm10 (12/23) and want to try jelly x. I don't know the difference between cfs and bfs though. Which version should I use? Does it matter that I have green lens anymore?

Thx
[Defy Android Development] niksy+:
Custom kernels are universal for both green lens, red lens and DEFY+! ;)

Now, my today experience with 22/12 CM10 + 22/12 JellyX CFS... Rather different than the one yesterday, I've got reboots now, as well.

Okay, so the way everything happened...

1.Was completely stable and on with WiFi on for ~8h

2. WiFi off for the night and that's another ~8h uptime

3. This morning while on the buss to classes I turned mobile data on. Battery was at 45% at this moment. Opened google, searched, opened page > 5 secs later > reboot

4. Booted up and rebooted again as soon as I unlocked it (mobile data probably got connected).

5. Booted up and I turned mobile data off with the notifications widgets as soon as the lock-screen showed up.

Battery down to 30%!!

That's 15% gone in a minute, literally a minute! Some data was wiped, too, but I'm not sure which exactly (the widgets remained intact on the screens, while my google account was gone, with all that was connected to it (phonebook emptied))

6. Was stable and on for the next ~7h with WiFi and mobile data off.

7. Got home 10 minutes ago, turned on WiFi and it rebooted 10 seconds later. Battery was at 18%.

8. Booted up again, turned off WiFi instantly, battery down 1%!! In 20 seconds?

It's recharging now and I have to say I will flash to 23rd Dec CM10 and keep Quarx's kernel for the time being... I'm going away for an 8 days trip with my girl on Friday and I need my phone completely stable, so I can use it every day as my navigation...

Again, my setup was CM10 22/12 + JellyX 22/12 (savagedZen governor + zen i/o scheduler, clocked together with vsels that I've been using without problems for 7 months now).

I wish I could provide a log of some kind, but no way of getting one post reboot, ay? :/

Blechd0se, I hope I have thoroughly explained how the reboots happened for me... It's very strange to me that WiFi was working fine for the whole first day and now isn't anymore. One last thing, I think that during that minute of mobile data it has used up ~50MB. I'm not completely sure on this, though! But I think it did and there were no downloads of any kind going on... Very strange, all this :(
[Defy Android Development] ccav2000:
I have the same kernel but with the default "Interactive" scheduler and no reboots so far. Using any other scheduler makes the power HAL that Quarx has implemented not to work and it's been known to cause such reboots. Unless someone finds a way to disable it...
[Defy Android Development] niksy+:
Hmm. Could be just that. Although it's a tad weird, because the previous build was never stable on other governors, no matter if wifi was on/off or mobile data on/off... Switched to interactive and it's running fine on wifi ATM! Will report if problems reoccur!
[Defy Android Development] juan296:
Excellent job blechdose,but.. one question..

Why cfq ? And why not bfq scheduler?:)

Thanks for sharing..

Arch Linux User ..
[Defy Android Development] niksy+:
I'm getting very similar Quadrant scores with all scheduler's... All are between 1150 and 1300, so...nothing to be concluded at all out of the scores, as we know that results with the same setup can differ like that.

Any other tips on how to test which scheduler would be the best? :confused:
[Defy Android Development] Blechd0se:
Don't trust Quadrant, it's not really reliable..

If you want to test with a benchmark, use AnTuTu and let it run at least three times and calculate the median, however you can test it better with some actual live test for example try to transfer some files over bluetooth or try to copy files and measure time. With my kernel you should expect some bluetoot transfer-rates around 80kb/s, with quarx one around 50 (depends on the load of your phone).
[Defy Android Development] niksy+:
No matter which i/o scheduler is selected in the menu? Silly thing, then, a choice with no meaning :cowboy:
[Defy Android Development] oSandmaNo:
Differences are minor :)

Using the latest CFS kernel on 23 cm10 and only interactive doesnt reboot my phone :D
[Defy Android Development] Blechd0se:
You should test each scheduler to find the best one that fits you. There are some differences, however you can only see them mainly in benchmarks.

In other words; changing the scheduler won't make your phone a nexus 4.
[Defy Android Development] niksy+:
Even though I wish that were the case, I know that differences are actually very minor... :rolleyes:

Anyways, anyone did a test-run the BFS version? I remember the phone was a bit jerky when I tried it...but that was just the first or the second version...

Mind sharing your setup, Blechd0se? :) (cpu clocks, scheduler, ksm, zram, swap...)

Dude,Right now stick with the interactive governer..The reboot and the system freeze issue is faced by many of us while changing governer other than interactive even on the Quarx Custom Kernel http://xdaforums.com/showpost.php?p=35866679&postcount=14139
[Defy Android Development] zakoo2:
Not true, i experienced the freezes no matter which governor i was using (tried interactive too). Now I'm on 22.12 quarx + 22.12 jellyx with savagedzen governor, and the phone works as it should, without freezes. Although it might be because i did a full wipe, and haven't restored any backup, not even titanium.

Hey guys I'm using the 22nd Dec rom with the 22nd Dec kernal of jellyx, wanted to know what sio & other options you'll have set to make it quick... Also the current voltages & clocks you'll are currently using. Also is there need to use ksm and zram?

Thanks, your help would be greatly appreciated..

Using the 22/12 BFS version, I notice that haptic feedback when I touch the home key is inconsistent. Many times there is no haptic feedback at all. The key works though, it's just a bit annoying, leaves you wondering if you actually touched the key.
[Defy Android Development] niksy+:
Haptic feedback malfunction is a know problem with the BFS version(s) :)

MrCurly, there's not much to set, really. You can change the i/o scheduler to deadline, for example. (I've been running some benchmarks, SIO gives by far the best SD write speeds, but deadline gets the best score overall).

zRAM, KSM... I don't know if these even make any difference... How can we check if zRAM is actually doing something? I've only left KSM ON and my phone's pretty fast anyway :)

You can lower vsels1 and 2, but the rest of the default settings that come with JellyX are pretty good. I set clk3 to 900 - vsel47 and clk4 to 1100 - vsel 55, you can give that a shot, if you wish so :cowboy:

Just a little report ;)

Am using the 22/12 build with my CNA 4.0 test build I compiled and am very happy the kernel is like it was before the reboot issues I have only had one random reboot due to stress testing the kernel after that changing the governor works perfectly ^_^ I even have it to auto switch after reboot. To make sure it was working i stress tested it by running a game while having some apps in the background including another game and it was stable :)

Thanks for the continued work Blechd0se :D

Currently running stable scary, deadline @1100 with heavy under volting on every clock speed

Edit - Just don't stress it out to much or it will reboot.

Edit 2- its back to being a bit unstable loooool :(

I tried to boot jellyx with cm7, but it failed. I dont know what i did wrong. I disabled the new gpu drivers, disabled TLS, disabled trace, but maybe i forgot something....

BFS or CFS? The choice is yours, some find bfs snappier and maybe it got a better multitasking, but really test both and decide for your own :)

i just love your little tweaks, and looking forward to testing the 5 freq steps, but i believe more builds are necessary.

as testing new build with delta in so many areas such as ext4 && 5_cpu_freq && mm, etc' might be very hard to test.

so having more builds in between would be great!

and of course, you're doing great work :good:

I see the update blog of Defy CM10 12.29, and I didn't find any package of ROM zip, when it will be uploaded?
[Defy Android Development] skeevydude:
Compiled your kernel with Quarx's CM10 last night (around midnight CST) and its working great on the Motorola Bravo -- though I haven't checked network or anything like that since my sim is in the Defy, but everything else seems to work just fine. Only 4 vsels showing in CPUSpy, but 5 vsels might not be fully done yet so I'm not giving a bug report or anything, just saying :p. On a very positive note, your kernel seems to make the Bravo run smoother than Quarx's kernel -- I have a lot less lag scrolling around the app drawer :).

[Defy Android Development] oSandmaNo:
Latest build uses the. 9 kernel. Maybe that could make a difference??
[Defy Android Development] Blechd0se:
It seems like not only my kernel is the reason for those issues with network, so be patient :)

Anyway i uploaded a new build today with many changes. Something i already talked about: ext3 filesystem will now be loaded with the ext4-driver.

If you have formated cache and data to ext3 (the default one) you are welcome to send me a dmesg-output :)

I also added the FSync control by Ezekeel. This let you decide if you want to enable Fsync

(slower performance, but maybe more stability for example after a reboot your widgets are not deleted)

or disable it (which is the default value and gives you some additional performance).

To control this simply type: echo 1 > /sys/class/misc/fsynccontrol/fsync_enabled

in the terminal. 1 = enabled, 0 = disabled (default). You can even put this in a init.d script for each boot.

If you have a reboot for some case, try in the terminal: cat /proc/last_kmsg

This was broken on the previous builds but should work now just fine.

I changed a lot of things, you can look at the changelog if you want to :)

If you have a black screen after installing, try to wipe data.

One last thing to mention: I already applied the commits from maniac103 GB branch to mine.

It simple doesn't work correct, however i didn't really spend much time on this.

I will try it again, this time directly without any of my changes. Maybe i can provide you JellyX kernel for cm7 too.
