Now I understand.

As the result of cuadrant, this is what you get. Galaxy Tab2 is so (not complex ;) )

Comparisons are only possible in one same device and see how the kernel can improve. Mine I assure you all that you can do (although I'm still working to try something else) and you'd have to compare with the official Codeworks. and before that with the official Samsung stock

The same I can say about the scroll. When it premiered (samsung stock) I was about to throw it away by continuous scroll jams.

At the time, I prepared my own kernel and found that ir improved, but not enough. I went to CM and the improvement was huge, so I keep well, and started working in the kernel. Later I got here, but that's another story.

Actually, my phone is much smoother in the scroll, thus keep trying to fix the problem, but right now, I am sure that no other kernel goes smoother. Simply, scroll does not depend on the kernel.

I hope my next version can be even better. :cool:
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] definator:
that would be cool, i am definitely sticking to your thread :)

right now kk seems to be smoother. but that really can belong to the rom i installed with it

the best kernel i have ever seen on xda is from anarkia [ http://xdaforums.com/showthread.php?t=1883298 ]

maybe u can get in contact with him. this guy is just awesome

he shares all of his work on github

if u could bring something in your kernel, this one will be flying away. believe me :)

and ps: sio is really much more snappier than the rest (except fiops, which is not yet present in tab2 kernels as i have seen)
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] tuxafgmur:
Well, if you think KK is smoother, I respect your opinion, but it has absolutely nothing that can make softer. Our differences are in areas that do not affect what you mention.

The rom using this kernel, if that may be different from CM in more than one point. I have not tested, but has very good references get, precisely because of its smooth running in various phone models.

However, I am reviewing the GPU drivers and libraries.

I have not tested thoroughly sio, but, what you claim is proven in galaxy tab?
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] definator:
maybe its really the same smoothness with your kernel in my current rom. i will maybe try

the thing with the schedulers in my opinion is, they work on all devices the same (nearly, if not modified)

and we really did huge testing of any parameter in AK kernel thread. depending schedular modifying / RAB / Fsync (dynamic) / zram / gpu oc and of cause governor tweaking

i will have a look what RAB is working the best with our tab2 read/write results

sio / fiops is what we really noticed the most smoothest schedular. its not always up to benchmark scores, but u can feel it. its all snappier and smoother

just find out yourself. row / cfq is **** against it

ps: if you wish i can try out some things you might be coding for the future kernel releases of yours
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] tuxafgmur:

I got the same thing, Power off system boot into recovery mode. Reinstall the CM rom without installing this kernel. Then download and put on the 6/28 version which works.

Getting it to booting into recovery mode is a real PITA. I had the best luck by powering it up with Power+VolUp and then rocking the volume up and down after the Samsung logo appears.

Dhollmen makes YouTube videos stutter

Hi,

I've tried the latest Dhollmen kernel and blobs with CM 11 on my P5110. Overall performance is perceptibly better than using the original CM11 Kernel, and there is no battery drain any more. But curiously, YouTube videos will stutter horribly using Dhollmen kernel. With the stock CM11 kernel, the same videos in the same wlan environment run very smoothly, so it must be a Dhollmen issue.

Any suggestions?

Thanks in andvance

Heiner
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] CSP III:
My suggestion would be to start reading back thru the thread, as this has been and will continue to be a common problem, for your answer or even better, just go back to original kernel and save yourself a lot of grief dealing with said issue. Some have it and others don't, including myself. Such issues, like the battery drain, are tab specific. It's not worth your time considering the age of there's tabs. Good luck
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] billysam:
This rom is unstable with cm12.1 rom on p5100, and omnirom 5.1 as well, flash it and it results in way more problems. I tested this on blispop v3.5 and it's working there as well no bootloop as of now.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] CSP III:
Known issues. These tabs are close to 4 years old. Lower the expectations and be happy with what we get. Nothing more stable than 11.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] billysam:
lowering expectations and be content? if someone hadn't been trying we would have stuck with ics my friend.

The reason we come here is because there are some people who still haven't given up and will keep on testing and removing bugs and updating, yes these tabs are old, but there are many possibilites. I never expected this tab to have even cm11, but my expection has grown over all these years. I am not giving up. this kernel and blob is working good with blispop v3.5, I have good battery backup now, no bootloops, its pretty much stable. no video and audio problems, no fc, even tested a 3d game, it wasn't that great but its ok considering the hardware limitation but you have swap support here and oc. right? don't be a noob. keep trying.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] CSP III:
OK Billy... A noob, really. Take a look, been around here for more than a minute. That being said, I'm just keeping it real. There are serious limitations with these tabs when pushing up thru 12. Take some time and read thru the threads. All the issues are there. Particularly been noted in Marko CM12 thread. Nice of you to show up to the party with your thoughts though. A tad late but but welcome. Before your next response, let's keep in mind the rules around here. The biggest one being No Trolls or Trolling. My post was not a personal attack Billy, so let's chill. If it's working for you and you're happy, great. There are many more who have found that 12 has just too many limitations running thru the Tab 2. Thats all I'm saying
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] billysam:
Sorry, If you feel offended by it, I know you've your share of experiences and knowledge, I am not here challenging that, but I don't like the idea of being stopped just because some people are feeling cm11 is the only thing that is stable and I do spend a lot of my time studying and experimenting myself in the background and I know you have been too.

It wasn't meant for trolling, it was for encouraging people to not be afraid of trying just because it has it's share of issues, but then our developers and testers here have worked so much to bring our tabs to this stage, it wouldn't do justice to all their hard work if people just stop at cm11. who knows who might pick up this project again, and work to make cm12 stable as well? thats all I'am Saying.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] fariez:
Second that. I've been a ROM-hopper for the past two years on this P5100, and just returned to OmniKat and Dhollmen kernel just to get a truly stable and fast enough experience, following a series of freezes and reboots induced by insufficient RAM on any available LP ROMs and kernels.

But I do hope Marshmallow might give this tab a new lease on life, should it be ported/compiled here by our finest developers. Fingers crossed, [MENTION=6063941]billysam[/MENTION]!

I'm sooo sorry for my epic stupidity, it didn't seem to be posted so I keep pressing back and submit on my browser.
[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] CSP III:
No offence taken. My last thoughts on this are as follows: many, many moons hundreds of thread pages ago it was determined that all these tab2 units are different from within. They all look the same, but each seems to have varying characteristics. (best example I have would be the infamous battery drain issue) meaning, what worked for some, didn't work for others. Many had the drain and many did not. What I'm saying is that while some may have had decent or even pretty good results with 12 and up, many others have not. If you are one of the fortunate ones, kudos to you but I say what's the point. I tired out on random reboots, freezes, crashes etc long ago, and being my tabs are 4 yrs old, I'm just happy they still even work at all. I'm not pushing my luck here

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] Shepguessed:
As said many times before, these tabs are all very different and a lot of experimentation is needed to find the right set up for yours. I have noticed that my tab runs best with dhollmen kernel when running 1460 MHz with 1410 or 1415 MV and 1420 MHz at 1395 MV. These tabs are very sensitive, my tab will reboot if I try to over clock 1460 MHz at 1420 or 1405 MV. It is a very small window. You need to find your tabs sweet spot.

[Galaxy Tab 2 (Unified 7" + 10.1") Android Developm] tuxafgmur:
As usual, the kernel is fully compatible with all AOSP roms.

Regarding the init scripts (inside of boot.img), could be some difference between each rom.

I've tried just on CM.

If there is issues into another rom you can upload the official boot.image and not problem to fix it.

Specifically, it is possible that the variable BOOTCLASSPATH is different in Init process, as had with LP kernel.

This was my mistake, this value must be for SDcard :o
