Waiting for the Great release ... ( Y3 - P601 )

No problem man ... so I'll wait for then ... about stick mount , I don't think so cuz I found that the HDD is going to need an external power supply that's not a good idea so I gave up on it ( No problem I'll cook my own kernel soon ... now I need to study for University entrance Exam ) ... Thanks again ...

With Best Wishes

Y3 looks great at first try..... Need to test battery. Any other governors than the 3 already in stock?

Voltage control ok with overall -75mv

I see more interesting stuf to test.....

I am back to 4.4.2 with OI1 custom from september first. All is fast but keyboard, not sure why. Need to review the rom creation process as i am also missing samsung boot screen too. Nothing to do with kernel.

I report for more.

Thanks for the great job.

What app are you guys using to control the voltage and stuff?
[Galaxy Note 10.1 (2014 Edition) Original Android D] enotar:
Kernel auditor for me
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
Good luck with your exam!

Thanks for testing! No other governors atm, will look into adding others if you've got any you prefer.

I'm using kernel auditor and the trickstermod app for almost everything, some stuff like thermal control / sound control from the Y3 test will need to be done by hand either using scripts or in terminal :)
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
if anyone on the 601 is running a COI1 rom, could you do me a favour and upload the ramdisk somewhere so I can get cracking on a new kernel for you guys :)

Y5 test build for sm-p600

same as the Y3 test but built with ARM-EABI-5.2 with some optimisations. no colour or voltage control as they were causing reboots, hopfully fixed next build. lots of new CPUFREQ governors, Random backport from 3.16+ (thanks to valex kernel again!) and probably some other stuff I've forgotten :P

EDIT: forgot to mention this is based on the COI1 ramdisk and the DOC1 kernel sources... I don't see any reason why it wouldn't work with roms before COI1 but I haven't tested it and won't be responsible for any bricking or damage to your device!

Hello xluco, there is an issue with this kernel: vibration don't work
[Galaxy Note 10.1 (2014 Edition) Original Android D] Stevethegreat:
[MENTION=5529656]xluco[/MENTION]:

I'm not much of a kernel guy, I'm mostly/only compiles one to add or remove features (magnet off, VT config , etc).

Anyway up to your later kernels ( Y2) I was able to make a .config file with no issue, but with your latest sources I get this

Any idea why/what that is? Even when I'm using your defconfig (xluco_defconfig). I never had such an issue with any other of the kernel that I've compiled down the years ... It's some command line option that creates the issue, but I can't just remove as it may well be important.

Thanks for your work (and releasing the sources of it)...
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
Thanks :) I'll look into it

That feature requires you to be compiling with arm-eabi-4.9 or above :)

P.s. my new github is github.com/phugh
[Galaxy Note 10.1 (2014 Edition) Original Android D] Stevethegreat:
Thanks

Hmm, I'm using Linaro 4.9.4 toolchain ... (I used to use 4.7.4, maybe for some reason it still thinks that I'm on 4.7.4 despite the fact that I've already chosen the 4.9.4 as my cross-compiler... I'll look into it)
[Galaxy Note 10.1 (2014 Edition) Original Android D] murigny64:
hello xluco.

Is it possible to create a LL kernel and port ramdisk from P900 5.0.2 ?

Then, we can perhaps port LL from P900 to P600.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
I have a feeling this might be a very stupid question, but its been a long day :P, what does LL mean?

hmm, strange, its definitely a new feature in GCC 4.9, I think you have to disable the stack protector option in kernel features in the config too if you haven't. Other than that I have no idea haha
[Galaxy Note 10.1 (2014 Edition) Original Android D] Orion116:
LL is lollipop[emoji6]
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
I honestly have no idea. If it's possible its far beyond my knowledge, I'm going to guess no though seeing as nobody has done it yet :P
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
Just got a score of over 40000 for the first time ever I think :)

Y5 proper coming tomorrow, compiled with new GCC 5.2.1, crappy governors gone, YeAH TCP control (westwood default for power saving), and a big fix for the Random backport. Just testing some VM tweaks before I upload!
[Galaxy Note 10.1 (2014 Edition) Original Android D] abdozzahra:
hi xluco

when it will be available for p601?

thanx in advance :)
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
as soon as I can get hold of a new ramdisk for the 601 :) theres a few changes in COI1 based roms so seeing as I can't test the builds myself I'd rather be safe than sorry!

EDIT:

Y5 is up on the first page :)

It has some network hardening tweaks applied so if anyone has any trouble with VPNs etc. let me know!
[Galaxy Note 10.1 (2014 Edition) Original Android D] Stevethegreat:
Hey xluco do you think on adding back undervolting? In embedded systems undervolting achieves the same results as over clocking on PCs as by preventing throttling it achieves better performance and as a bonus it also achieves less heat generated and gives better battery performance.

The LP/AOSP guys managed to add undervolting without causing instabilities. So I think we have hope.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:

[MENTION=5529656]xluco[/MENTION]: Once again your COl1-Y Kernel proves temperamental to compile. Are you sure it even compiles? I mean your COl1-X Kernel compiles with only a few warnings but the COl1-Y Kernel stops to its heels.

It brings me the following error

amongst others...

I have put "arm-cortex-linux-gnueabi-linaro_5.2" 's Bin folder in my cross-compiler path, and it pretty much compiles everything except your COl1-Y Kernel. Can you check it please? Maybe there's something missing on your sources?
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
Hey man, I wouldn't recommend compiling COI1-X thats just where I was trying to stage the 3.4.109 patches.. didn't work very well!

I'll check that everything is pushed properly to github but I'm pretty sure it is. I'm using this toolchain: https://bitbucket.org/UBERTC/arm-eabi-5.2 , if you try doing "make distclean && ccache -C && make xluco_defconfig" and then try building with the same toolchain does it give you the same warnings?

I won't be able to check anything till I get home later tonight, if you're desperate to have something compile you can just add -Wnoerror=maybe-uninitialized to your makefile to supress the warnings (most of the 'maybe-uninitialized' warnings appear after adding -O3 and other CFLAGS, so maybe try playing around with those too, especially if you're trying to use the linaro toolchain (edit: you can revert this patch to remove all the CFLAG tweaks - https://github.com/phugh/SMP_600_KERNEL/commit/e99e7c9be6da175650b3f742d8ff65523dda9c12) :D
[Galaxy Note 10.1 (2014 Edition) Original Android D] Stevethegreat:
OK, I'll try it and report back. If it's indeed to work it would be curious that it does not want compile using Linaro...

Thanks for the tip :)

edit: Yeah it worked. Apparently there's something to your latest patch that makes your kernel unable to compile using Linaro. Instead of reverting the patch I would prefer if I could find a way to work around it and let Linaro compile it. Hmm, I'll prolly look into it when I'd find more time.

Cheers man!
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
It's probably the graphite stuff, tbh I was going to revert the CFLAGS in the next build anyway, they don't seem to add anything other than making the kernel much bigger!

Y9 and Y9-VT are up on the front page!

Just bug fixes really, updated GCC compiler, dropped the CFLAGS, changed UKSM for regular KSM which should improve battery, fixed the tablet booting in performance mode which was causing me sleep of death problems. Enjoy!

I'm dropping support for the 601, I'm too busy / can't get hold of ramdisks / can't be arse spending hours downloading the 5.1.1 sources.

As always, if you're running the VT version, booting will take a lot longer.

Hey please don't forget to also compile a VT version so that I can update my Linux guide for Lollipop. I mean I can already "have" Linux on Lollipop by compiling from sources, but I would had much preferred to point users to your kernel (than merely have each and every one compile their own VT kernel).

Cheers BTW
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:

Got the unauthorized change message too and apply. No differences after reboot, not sure.Wifi password are lost after reboot. Messaje comming back. This is a security stuff.

Also getting wifi amnesia.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
I knew I'd forgotten to add something to the ramdisk, will add the ro.securestorage tweak tonight :)

Its essentially all the patches from Y9 except the stuf to make it compile with GCC 5.2.1 :)

I get that every so often too, not sure what its about, I got it with the stock kernel that has chainfire's modified sepolicy too so it might be DM_VERITY or something, but who knows :P

Thanks everyone for testing :D

[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
Yeah I get the same when I try and undervolt, theres nothing wrong with the commit to enable voltage control, its just the Exynos chip seems particularly sensitive to voltage changes.

I'll see what I can do. The problem I have is that I can't find a consistent set of F2FS patches for the 3.4 kernel, so if anyone knows where I can get those it would be a big help :)

[MENTION=5529656]xluco[/MENTION]:

Hey xluco, I see that you took down your KitKat kernel which renders my Linux guide unworkable for a lot of people (for those who don't know how to compile a VT kernel).

Would it be too much to ask from you to continue hosting the KitKat kernel (at least the VT version of it), or if that's not possible to have your permission to host it myself?

The reason I'm asking is because my preliminary results with Linux on Lollipop are not very encouraging. There are some permission errors that I'm encountering but even when I fix them I get lower performance than in Kitkat (about 50% percent lower at times) so I'm thinking to recommend for people to whom working on Linux is important to stay on KitKat. Of course I'm going to update my guide for Lollipop too, but the results leave much to be desired. The total performance of Lollipop (at least up to this point) is quite less than that of KitKat in both Android and Linux... So -yeah- I would need a well-made KitKat kernel for that.

Thanks for your work anyhow.

Bye now.
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:

[MENTION=5529656]xluco[/MENTION] What toolchain are you using for LP? Im trying to backport f2fs but getting a lot of errors for other untouched things. Maybe [MENTION=4898097]arter97[/MENTION] can help us get f2fs backported? :)
[Galaxy Note 10.1 (2014 Edition) Original Android D] diabl0w:
using ndk 4.8, i was able to compile an error free zImage by doing the following:

https://github.com/unleashed/f2fs-backports

patching using the base files in order, then 3.5 patch in order, and then only files 001, 006, and 007 from the 3.2 patch in order. after building defconfig and menuconfig then navigate in menuconfig to filesystems > misc file systems > f2fs and enable it

i tried to make this into a boot.img but never did it before so i mightve messed something up... doing this, i got a bootloop. I am pretty sure we need to modify something in ramdisk (you probably know all this already but im just trying my best to get something moving) and also modify the updater script (maybe some leads can be found here: http://xdaforums.com/showthread.php?t=2694201)

there was also a kernel version 3.4 backport here: https://github.com/OPNay/android_kernel_samsung_jalte/releases

Z1 GPU OC

I was running on an old version of the kernel (V3?) before I upgraded to 5.1.1... The main reason I liked that kernel so much is because of the GPU OC.

I just flashed Z1, but it's not clear to me whether this version also allows GPU OC. Is this the case, and if so, how do I do it?

I remember I had changed some config files for the previous version, but that was more than a year ago :)

Thanks in advance :*

Great news on behalf of Xluco, he's having issue with his account, so he asked me to release this new test build with GPU Overclocked up to 800mhz but it doesn't yet allow to control anything related to it.

Damn, I'm using the same code from the kitkat kernel minus the voltage control / ability to control the OC.. it should just be set that the maximum freq. is 800mhz. What tools are people using to see the GPU freq? I can't seem to find one anywhere!
[Galaxy Note 10.1 (2014 Edition) Original Android D] xluco:
It's not something you can enable / disable, its just always turned on :) its not an actual scheduler, its just kinda like extra instructions for how the scheduler should handle multicore processors. You can, however, configure some extra power saving settings now that its enabled:

echo 2 > /sys/devices/system/cpu/sched_mc_power_savings;

(0 = off, 1 = moderate, 2 = aggressive (Z1 default))

Install this small app, run it, and then press the back button next to home button. Then you will see at the upper left corner of the screen the information that this app displays. I hope this will help to have a better kernel. Also I think that gpu scaling should be more aggressive. If there is a gpu governor it would be good to tweak it.[emoji4]
