My 2100 mah car charger is detected as usb so the device only charges with 900mah. Why don't you offer the option to customize the charging currents?
[Galaxy Note II Original Android Development] AndreiLux:
Instead of asking why something isn't in the kernel I'd prefer if people ask for me to include it into the kernel, the other way sounds kind of rude.

As why I didn't implement it yet it's because I had some other higher priority things on the list which affect more people and bring more to the kernel. And because I didn't want to implement the charging modifications of some other people because I believe they aren't optimal or working well. I need to check more on the behavior of the charger chip and the mfd code to actually understand what is going on there.

Version 28 was an I/O overhaul to bring some advanced schedulers into the kernel, and I spent a lot of time analysing and understanding the block driver model of Linux, and while I really regret that exFat had to die for it, it brings more benefits to the greater amount of people. I prefer to actually fully understand the changes I bring to the kernel.

I will look into charging in a later version as I planned other goals for v29.
[Galaxy Note II Original Android Development] quertiy:
I asked "why don't you add the option" as in: do you have a reason (like not being safe) or people just didn't ask for it or you plan to but didn't have time. But I see how it can be wrongly interpreted given that everyone asks for everything. And I agree it's on the bottom of the to do list. I'll just temporarily change the kernel for the 2 day car trip as copilot and full brightness need more than 900 for the phone to not discharge. Thanks.

Dear OP,

Can you please bring this kernel to the Verizon Galaxy Note 2 it is fully unlocked now :)
[Galaxy Note II Original Android Development] gundal:
I just updated my post on page 116 with 5 cwm flashable Profiles for the perseus kernel, for people who dont understand the concepts of OC/UV.

And another for governor tweaks if you feel the cpu is too aggressive at scaling up.

Hey Andrei,

I'm not sure wether I missed something, but I'm not able to activate the new fsync-feature in the STweaks application. After an application restart it is unchecked again - despite of checking and applying it before. I had a look into the sysfs and found out, that there is no /sys/kernel/dyn_fsync/ folder on my phone. Is it just me or is it a general problem?

Bushido
[Galaxy Note II Original Android Development] antt00:
Confirmed i do not have that folder as well and thus fsync selection does not stick.
[Galaxy Note II Original Android Development] Dnssuffix:
NO FSYNC folder nor the fsync enable
[Galaxy Note II Original Android Development] CekMTL:
Yep confirmed no fsync object in tree.

Thx Andrei for your legendary and edgy work on kernels!

[Galaxy Note II Original Android Development] questionmark:
ExtFat is a nice addition to me by Samsung and quite transparent... though it's proprietary. TWRP supports it and it's nice doing backup on it. I also use UMS mode to transfer flawlessly and fast > 4gb files.

So if exfat support will be out of the kernel what is the best ext4 or NTFS?

Considering the need of doing nand backup on external card, and the need to copy +4gb using ums mode from a win machine.

I guess ext4, TWRP probably supports it? as for transfer in UMS mode I guess doing from a linux box would do but not from a win machine.

Does ext4 mount automatically or need to use APP for this?

Thanks
[Galaxy Note II Original Android Development] mitchelln:
I can't get my N7105 to mount an ext4 formatted sdcard no matter what I try. The auto mounter seems to insist on using a virtualized fuse based method that doesn't recognise ext4. I can't even mount the card manually as there seems to be no accessible raw device to mount. It's all intercepted by the aforementioned mount code.

I've tried Paragon and a couple of other similar apps, but none of them can successfully mount an ext4 formatted card. The Samsung/Google proprietary crap getting in the way here and no one seems to have a solution unfortunately.

Any help here would be greatly appreciated. It really annoys me that Android has been made deliberately incapable of mounting ext4 sdcards when it uses the file system itself and everything is present in the kernel to support it.
[Galaxy Note II Original Android Development] Conan179:
Can you do something with the kernel, so that the Battery Widget https://play.google.com/store/apps/...r#?t=W251bGwsMSwxLDEwMiwiY2NjNzEuYm13LnBybyJd 10sec pro all of 3c. can read the consumption?
[Galaxy Note II Original Android Development] AndreiLux:
Ok I thought about it and changed my mind... There is a lot of users using the kernel and it's a fairly large amount of people who may use it.

I'll bring exFat back. I'll see what from the changes I can salvage so it'll take a bit. In the meantime stay with the previous version.
[Galaxy Note II Original Android Development] EdgaBimbam:
Maybe you could make two versions, one with exfat support other without. If it isnt so much work to do for two versions :)
[Galaxy Note II Original Android Development] AndreiLux:
It's too much work, there's about 3 pages of commits related to 3.3 and I don't want to bother having two different builds like that.
[Galaxy Note II Original Android Development] jauhari:
Does on stock kernel your charger display correctly and not 900 value?
[Galaxy Note II Original Android Development] nyarnon:
Really a pitty it can't support both extfat and ext4. I would favor a good ext4 implementation anytime especially if there would be a CWM that could support mounting it.

Was running 200@700 just to be clear, then ok ossom...will try to go lower on 200...maybe it can take 675 xD but I am impressed and happy with exynos :)

Unfortunately I've gotta go up by +25mv on most of the voltages for it to be stable on my phone :(

What are you using to test the stability? I'd like to see which of the speeds/voltages was giving me trouble.
[Galaxy Note II Original Android Development] CekMTL:
Search in market for stabilityTest.

Lock each step of cpu frequency that you want to test, in setcpu and switch over to stabilitytest and run first test.

Example : say I want to test stability for 800 mhz, I'd go to first tab of setcpu, and limit the higher speed to 800, then switch over to stabilitytest and test it.

Always have a backup handy just in case!

Good luck ;)

Btw: 200@675mV has been running stable all this time... maybe tomorrow I will be able to publish my N2 definitive UV map :)

So far so good.

I am using this list;

1.800 Mhz @ 1.250 Vcc.

1.704 Mhz @ 1.175 Vcc.

1.600 Mhz @ 1.125 Vcc.

1.500 Mhz @ 1.075 Vcc.

..

Are these voltages higher than stock? Till 1600mzh that is? Guess they are way lower but phone getting bit warmer then with stock kernel.

Encountering one issue till now wich i got after installing the kernel

I am using TW launcher and have made some folders on the homescreen with shortcuts in it, one of them is play store

When i open the map and then go to playstore nothing is wrong. Browse some apps and then use back button till i get back to homescreen and then the opened map is stuck and then i get forced close TW launcher.

I only have this with this kernel installed. kinda weird

Anyone having this?

[Galaxy Note II Original Android Development] dachness:
http://xdaforums.com/showpost.php?p=32683267&postcount=81
[Galaxy Note II Original Android Development] AndreiLux:
I think I'll keep the default kernel only up to 1800, the voltage jump to 1900 is too big for it to be used as a daily driver, and nobody reported 2000MHz working. I'm sure the physical silicon would be able to handle these speeds, but the're running into limitations of the SoC design itself, I cannot reduce some clock dividers for some auxiliary CPU clock blocks any further because the dividers are already at their maximum from 1800 on.

Also, I would like if some people knowledgable with "dock-OTG-charging" would read this post. I got a request for it but the person isn't answering.
[Galaxy Note II Original Android Development] CekMTL:
Interesting, but for now can't test it as I don't have any kind of dock for my N2.

Thank you!
[Galaxy Note II Original Android Development] radjeshsitaram:
Getting slow after idle for me.

After restarting my note its working very good but when i leave my phone for like an hour and then use it again it has bad performance.

No problem with the clockspeeds or temp, cpu is just performing with half number results in every bench program

After a reboot its good again till i leave the phone for some time

[Galaxy Note II Original Android Development] EdgaBimbam:
you wont find...

Use the cf kernel, its stock only with root.
[Galaxy Note II Original Android Development] AndreiLux:
And why not? ...

Anyway here you go. I also uploaded it to the 2nd post.

CF-Root is not a kernel, it's a recovery. Kernels are no longer related to root on these devices.

1800 @ 1239 mV (Yes... can't seem to make it accept 1237,5 how?)

So there you go, now time to test them for a few days and see if something weird happens, but TBH, if it din't fail StabilityTest with 4 cores @ 100%, while testing memory at the same time, when the power juice is in highest demand... donno...

Where can we download older versions? I want 27 because 28 sounds like a bit of hassle.

Great work, love the kernel and is undoubtedly the best available for the Note 2.
[Galaxy Note II Original Android Development] AndreiLux:
I reverted the 3.3 changes. FIOPS had to die for now. exFat works again. ROW still prevails. Fixed the Fsync not working. Added the NFS changes from Bushido.
[Galaxy Note II Original Android Development] questionmark:
+1000 for people that can change there mind! Some other kernel does not support it and for me it's a blocker and perseus would have lost IMO an important functionality.

[Galaxy Note II Original Android Development] mitchelln:
Thanks for putting exFat back. Best solution for now I guess for us people with 64GB sdcards and HD content.
[Galaxy Note II Original Android Development] quertiy:
I don't understand why is it so hard for people to accept ext4 considering the amount of kernel upgrades in performance and whatnot. From what I read the only setback is the fact you have to mount the sdcard with a special program in Windows. It just can't be that much trouble. Can it?!

Correctly on stock means 450. On perseus it's 900, on neak 1700. Keep in mind that I'm talking about the usb charging method. It's not a fault of perseus's kernel, it's just not upgraded enough.

Same here ext4 would be okay though I did not try as it seems there are issues. The exfat is just working and was working and it's native 64 gb sdcard format... Not having it would mean less feature and more hassle. Yet still ext4 would be also greate... Hate not being able to make symlinks...

Can't get 28.2 working on 7105

Tried flashing over top with CWM zip via TWRP. Reboot - screen flickers, then fades to black and only comes back on with 10 sec power cycle.

So then I did full wipe, reformat etc and installed clean rom with 28.2 and same boot screen, but flickering yellow screen then same cycle above, fade to black.... and yes checked, rechecked, re-downloaded to make sure I had the 7105 marked kernel

Stumped as all other flashes of your kernel have had no problems.
[Galaxy Note II Original Android Development] AndreiLux:

[Galaxy Note II Original Android Development] fishingfon:
Hi,

Is the source code available for the note 2 version of the ramfs?,

As I want to compare the partition layout in it to a dual boot kernel I am compiling, but i can only find the ramfs source code from the S3 (which has a different partition layout)

Thanks

[Galaxy Note II Original Android Development] AndreiLux:
Just extract it from the kernel itself, I stopped bothering with keeping repositories for the ramfs. I change almost nothing outside of the res and sbin folders.

AndreiLux,

Thank you very much for bringing this over to the verizon note 2. Do you have any plans on making a CM10 compatible verison of your kernel?
[Galaxy Note II Original Android Development] :
Im also having the bootloop issue. After flashing the kernel it would be stuck in a reboot loop for about 5 or 6 times, then finally rebooting successfully into touchwiz. No reboot issues after that.

I thought something went wrong during cwm flashing so i reflashed it again just to be sure, and sure enough reboot loops for a few times then no issues after that.
[Galaxy Note II Original Android Development] Cyclonut:
Flashed through trwp and booted just fine (Sprint variant). Then went back in and flashed gundal's profile 5G and it seems to be running super smooth since last night. Seems to have made my unlock pin screen lag go away also.

With this setup would it be wise to run power saving mode or is it not needed? TIA!
[Galaxy Note II Original Android Development] AndreiLux:
No CM10 plans in the near future.
[Galaxy Note II Original Android Development] jamexman:
I too have the sprint one. I flashed 5G and it's running amazingly. Ill report battery life in a couple of days. You do the same if you can. I'll do it in tbe sprints kernel thread not to clutter here.
[Galaxy Note II Original Android Development] quepaso:
I did a quick search, but did not come up with anything conclusive. As im sure you know, the Note 2 display runs at 58.002FPS instead of the 60.0 standard most other devices run. Is there anything possible to fix this back to 60 or is it not possible via kernel? Thanks.
[Galaxy Note II Original Android Development] AndreiLux:
The display is defined at that frequency:

static struct s3cfb_lcd s6evr02 = {
.name = "s6evr02",
.height = 1280,
.width = 720,
.p_width = 69,
.p_height = 123,
.bpp = 24,
[COLOR="Red"][B]	.freq = 58,
.freq_limit = 41,[/B][/COLOR]

/* minumun value is 0 except for wr_act time. */
.cpu_timing = {
.cs_setup = 0,
.wr_setup = 0,
.wr_act = 1,
.wr_hold = 0,
},

.timing = {
.h_fp = 70,
.h_bp = 40,
.h_sw = 3,
.v_fp = 13,
.v_fpe = 1,
.v_bp = 1,
.v_bpe = 1,
.v_sw = 2,
.cmd_allow_len = 7,	/* v_fp=stable_vfp + cmd_allow_len + mask_len*/
.stable_vfp = 2,
},

.polarity = {
.rise_vclk = 1,
.inv_hsync = 0,
.inv_vsync = 0,
.inv_vden = 0,
},
};

I already dwelled into the lcd frequency on the S3:

The last time I tried to change the frequency even by a few Hz the display driver crashed and the screen went black for a bit before restarting with some default values. Since I don't even have a Note 2 I cannot go that far into trying those things out. The problem is that I don't really understand the meaning and uses behind the timings and what they represent in reality. Maybe somebody can look over the User Manual and see if they get smarter from it.

I had concluded that the Note 2 had 58Hz because the base clock from the MPLL is 880MHz and not 800MHz as the others and the dividers couldn't be set up to provide the exact clock the display controller needs.
[Galaxy Note II Original Android Development] gundal:
Yes, it still works. the override.profile is now part of kernel and will always be unless andrei decides otherwise.

it was only present in 28.0 which broke exFat filesystem for sd cards

so the changes had to be reverted to restore exFat compatibility

hence 28.1 and 28.2, ps this is all right in the original post ;)

Thank you for the detailed reply. I am beta testing a new Emulator for android called Retroarch which has no frameskip, so it always goes for 59.95fps. On the note 2, everything stuttered like mad. Its when we discovered that the display runs at 58 and now the app looks at the refresh rate first, then caps it there fps wise. Would have been nice to have gotten 60fps but not too big of a deal.
