My friends, let me congratulate this dev for his awesome work.

I got my tab today, rooted it, flashed this kernel with CWM and the gadget is running great . I am using SetCPU-

I also installed Nova Launcher.. running great

Im amazed we can do all this the first day with a $249 tab

BTW, somebody asked for storage support. I am using the media connection and transfer files this way. No big deal .. you can see both SD´s.

Cheers
[Galaxy Tab 2 7" Android Development] slopokdave:
Mine runs warm along the left side (holding in portrait) even with the stock kernel.... curious to feel this kernel after.

So I installed the kernel and my microsd is not mounted as /sdcard2. What am I missing?
[Galaxy Tab 2 7" Android Development] dsb9938:
What does it say for kernel version under About Device?

[Galaxy Tab 2 7" Android Development] slopokdave:
Nevermind! I see it now. Had to backup a couple directories, I was looking at the old mnt/extSdcard, it's still there.

So how does this help with using it for app storage? Or, does it? Thanks!!!!
[Galaxy Tab 2 7" Android Development] dsb9938:
Yes, I just did a link. I did not remove the old mount.

I just did it for convenience. I have no idea if it will help with app2sd at all.

[Galaxy Tab 2 7" Android Development] dsb9938:
Sorry, somehow I missed your question.

No, I can't put it there. I did create a symlink for it to /sdcard2/ though.

Removing the int-sdcard from that spot, or the ext from where it really is, is something I do not wanna get into. I do not know what effect this would have on things that expect them to be where they are.

can it be used in P3100?
[Galaxy Tab 2 7" Android Development] Nicene Nerd:
Thanks, anyway. I think I found a solution. If I run "mount -o bind /mnt/extSdCard /mnt/sdcard/External" on a terminal emulator before I use Alt Mounter, I can access the external SD card.
[Galaxy Tab 2 7" Android Development] dsb9938:

If you are going to try it, you should have something already in place if it fails.

Has anyone been able to connect to a smb share with CIFS support? I've tried mount -t smbfs etc.. at a terminal prompt and CIFSManager and I can't connect. I can ping the share IP.
[Galaxy Tab 2 7" Android Development] tonysohn:
Thanks for this great kernel. But when I flash this kernel to my stock GTab2, it boots normally and then after a few seconds, my tab reboots. I'm suspecting that one of the apps I installed is causing the boot loop, but can't find out which one it is. I'll probably have to do a data reset at some point.
[Galaxy Tab 2 7" Android Development] dsb9938:
I'm running it, haven't had any other complaints.

I've used cifs with other devices and it requires at least cifs.ko (and maybe tun.ko) and the insmod command should load it. When I run insmod /lib/modules/cifs.ko I get a failed error message ...file not found. The file cifs.ko is there but I'm suspecting a dependant ko is missing.

I've used SetCPU for a long long time.

Nice work on the kernel. Too bad I can't use it on AOSP/CM9.

Make sure you look at the bottom of the OP for how to enable ZRAM, it really does make things noticeably faster.

[Galaxy Tab 2 7" Android Development] lightofhonor:
Quick (maybe dumb) question. Running through benchmarks (namely antutu) I noticed the Galaxy Nexus gets almost double the frames on the 3d elements than the Tab even though the gpu is overclocked. Since I know the gpus are the same, is this something else that is different between the 4460 and the 4430? Bandwidth maybe? Just wondering if its something software.

Great kernel.
[Galaxy Tab 2 7" Android Development] dsb9938:
I honestly have no idea. Sorry.

D

.
[Galaxy Tab 2 7" Android Development] tonysohn:
Awesome! Thanks for the update. Do you have to run the zram enable command every time you reboot, or does it stick?

BTW, adb wireless (search from play store) works great for this device, so you don't really need a USB cable.
[Galaxy Tab 2 7" Android Development] DesDr0id:
I'm wondering the same thing. If anyone can confirm/deny this, it would be much appreciated. FAT32 has single-file size limit of 4GB -- NTFS microSD support would address this limitation.
[Galaxy Tab 2 7" Android Development] RMXO:
I tried it & didn't work for me but being able to OC my tab evens it out. Shame my tab can only go up to 1.2.
[Galaxy Tab 2 7" Android Development] dsb9938:
Once you turn it on it will stay on.

D

.
[Galaxy Tab 2 7" Android Development] tonysohn:
Okay, thanks.

I just found out that my tab can't even handle 1200Mhz -- reboots every time I apply 1200Mhz. :(

Are there any plans on adding a clock step between 1008 and 1200Mhz, like 1100Mhz?
[Galaxy Tab 2 7" Android Development] dsb9938:
No idea yet. But I can tell you, some of them can't handle anything over stock speed.

[Galaxy Tab 2 7" Android Development] tonyzoc:
Same for me. 1.35 causes me lockups and reboots.
[Galaxy Tab 2 7" Android Development] lightofhonor:
Just noticed that the fps never goes above 30 until it hits 60. Is there vsync locked in the kernel? Can this be fixed?
[Galaxy Tab 2 7" Android Development] nphil:
This is a good observation, I've noticed the same thing in numerous benchmark apps. It's either 30fps or 60, nothing in between. So I guess it's vsync.
[Galaxy Tab 2 7" Android Development] lightofhonor:
And nothing over 60. So while it may not be a major issue since 3d will be smooth, it does make for less than impressive OC results :/ lol The 60 fps limit was on my vibrant too so it may be a PowerVR issue, but modders were able to raise that some and there was no 30 fps lock.
[Galaxy Tab 2 7" Android Development] Metallice:
You all can probably run 1350mhz just fine. The issue is most likely SmartReflex. Since its using the same FUSE_OPP as the 1200mhz slot (as there is no 1350 fuse), its voltages will be calibrated as if it were 1200mhz and may therefore be too low for 1350mhz on your device. Smartreflex usually pretty conservative so for most devices the 1200mhz FUSE_OPP will be sufficient. So you might have something like 1000mV for 1008mhz, 1210mV for 1200mhz, and 1260mV for 1350mhz. For some, it won'tbe enough volts, and will reboot. You can disable SR through sysfs and run 1350mhz fine but it will kill your battery for all freqs.
[Galaxy Tab 2 7" Android Development] Metallice:
Samsung did the same BS with the CPU frequencies so im not surprised they did this with the FPS. As of right now dsb's kernel still has this behavior. The CPU will "lock" itself at certain frequencies for whatever reason and will boost itself whenever a finger is present. AKA a lag inducing/unresponsive-making tweak and a battery wasting tweak...
[Galaxy Tab 2 7" Android Development] tonyzoc:
Now I just need to Google SmartReflex anf sysfs and figure out how to do it. Thanks.
[Galaxy Tab 2 7" Android Development] Metallice:
Our CPUs use a technology called SmartReflex to automatically calibrate voltages for 300mhz, 600mhz, 800mhz, 1008mhz, and for 1200mhz (thanks to the GNex's 4460 originally having 1.5ghz). It does this based on your specific cpus tolerances, cpu temperature, and other factors. The GNex uses SR 1.5, which is software level calibrations. The 4430 we have uses hardware calibration which is much better. Essentially it dynamically chooses low, stable voltages for the most part elimination the need for custom undervolting (especially since we have v3).

Sysfs is all the debug stuff in the sys directory. Some of the "files" contain values which can be changed for whatever effect. For example, sysfs is how apps like setcpu change the governor, min/max, etc.

To disable SmartReflex (remember, will kill your battery), either type the commands below into "Terminal Emulator" app on your phone (will reset on a reboot), or you can put them in a file name ##filename in init.d to have them run at every boot. So for example you could make a file named "96sroff", copy these commands in and save, and then copy it into /system/etc/init.d/ and set its permissions to -r-xr-xr-x (i think?).

echo "0" > /sys/kernel/debug/smartreflex/sr_mpu/autocomp

echo "0" > /sys/kernel/debug/smartreflex/sr_core/autocomp

echo "0" > /sys/kernel/debug/smartreflex/sr_iva/autocomp

1 is on, and 0 is off.

MPU refers to what we typically think of as CPU frequencies

CORE refers the GPU

And IVA refers to the hardware media decoder.
[Galaxy Tab 2 7" Android Development] tonyzoc:
Thanks again....I might try it out but for a 5% improvement over 1200...I'll probably keep my battery life.
[Galaxy Tab 2 7" Android Development] marcosxd:
Thanks for your hard work

Is there any room for improvement in your kernel? Still working on it? Thanks!.. no flaws to report yet.

When OC to 1350mhz it has some hiccups.

Running at 1200mhz without any issues.

Using SetCPU for OC.

Thanks for all the hard work!!!

I need to find time to enable zram, how is the performance improvement with it enabled?
[Galaxy Tab 2 7" Android Development] tonysohn:
I really wish my tab can handle at least 1200 Mhz. The moment I apply it, my tab reboots :(

It's nice to have if you need to charge off a USB port, but annoying to turn on and off by hand.

I don't know if this is specifically a problem with this kernel, but I first noticed it after flashing update 4. The automatic brightness never works properly anymore. Unless I put the light sensor directly under very bright light, the brightness stays to a minimum.
[Galaxy Tab 2 7" Android Development] dsb9938:
Haven't messed with it, and I wouldn't notice because I don't use it. I do it manually.

But, like I said, haven't changed anything with brightness.

I don't know if you meant to do this, but I'm now getting max 33 and 67 fps in benchmarks instead of 30-60. Purposely done? Does this mean you can increase/remove it?

So after installing the newest kernel, my battery life seems to suck pretty bad now, even when its not overclocked. When I use cpuspy to checkout the frequencies, it spending the majority of the time at 300MHz instead of deep sleep.

Is it suppposed to be like that?
[Galaxy Tab 2 7" Android Development] dsb9938:
First, your battery life will never suck on this tab. Go try a Thunderbolt.

Second, I would say you have an app doing something, or you have selected a governor that does not sleep.

My tab spent the last 4 hours in sleep mode.

D

[Galaxy Tab 2 7" Android Development] xreflection:
16hrs to go from 100% to 45%..that's pretty suck if you ask me. I had like 2 apps in the background and didn't really use the tablet at all during this time (I actually misplaced it for most of the day). Anyway, what governor should I use?

[Galaxy Tab 2 7" Android Development] mazuka:
dsb9938, thank you very much for the kernel - immediate improvement about 30% per antutu benchmark compared to stock, and no issues so far.

The only question - how to mount an NTFS-formatted sdcard? It still does not seem to recognize NTFS; do I have to enable something via command line, similar to how zram is enabled?

And again - great work, and do not let unappreciative comments get you down.
[Galaxy Tab 2 7" Android Development] dsb9938:
I honestly have no idea how these things work. I have never used them. Sorry.

D

.
[Galaxy Tab 2 7" Android Development] mazuka:
I see... but you did mention you enabled NTFS support in the kernel, so you did something, probably some flag in the kernel? I am just trying to figure if I shall continue trying to mount given it supports NTFS indeed.

Thank you
[Galaxy Tab 2 7" Android Development] dsb9938:
I did enable it, it did produce the modules. I found something to test CIFS, but not NTFS, so I dunno what to tell you.

Even having been able to test CIFS, I have never actually used it.

You can try the AOKP version, the only difference is that the modules are not only built into the kernel, they are installed on the device as well.

If I'm not mistaken the kernel is for AOSP and CM9 build ROMs which means it is not compatible with the STOCK ROM . At least that is what I read somewhere, you can't run CM9 compatible kernel on stock n vice versa.

[Galaxy Tab 2 7" Android Development] mazuka:
boot loop on P3113 stock 4.0.4

I enjoyed this kernel very much while on stock 4.0.3 but after updating to stock 4.0.4 an attempt to CWM the custom kernel resulted in a boot loop. I will continue trying though.

For anyone trying the kernel with 4.0.4 I strongly suggest to do CWM (nandroid) backup first.
[Galaxy Tab 2 7" Android Development] ricardowec:
Why would you do so?.. you risk bricking your tab. More so, the Kernel does not have support nor updates as the dev sold his tab.

Just forget about it. I am running Stock 404 (rooted) with stock Kernel and my tab flyes.

It wasn't that great as I had freezes and reboots at 1300 + so I had to top it at 1200 which does not make much difference with the new 404 Kernel.

[Galaxy Tab 2 7" Android Development] mazuka:
You probably right, but I came from g tablet that had (and have) tens of custom ROMs and a number of great kernels with OC up to 1.6 GHz, so for me an android tablet must have a few OC kernels, even if just for the sake of it, it is like a symbol of popularity and wide acceptance.

Besides, mine had no issues with 1.3 GHz; and Antutu test results show - 6312 at 4.0.3 with the OC kernel, and now 4952 with 4.0.4 and stock kernel.

So you see, this partially subjective but partially objective.

[Galaxy Tab 2 7" Android Development] slimzim:
I would just like to reiterate what's already been posted that this kernel is for 4.0.3 - it will lead to bootloops on 4.0.4.

It appears that the devs have mostly moved on from this device, but with Samsung's student edition of this tab just being released ($250 for the 8gb Wi-Fi model w/ keyboard dock) a lot more new owners of this device can be expected to be looking to use this kernel (myself included). Because of the Samsung keyboard dock, most of us are probably going to want to use the stock ROM - the dock doesn't work with CM9/AOKP, so this kernel very desirable! I'd be willing to donate if anyone can update the kernel to work with 4.0.4.

I did try to run my 3113 with 4.0.3 but after rooting it (used this method http://xdaforums.com/showthread.php?t=1788625) the device ran so slow that it was basically unusable - it would take almost 10 seconds to switch from portrait to landscape, changing launcher screens took 3 seconds, etc. Has anyone else experienced this? Using dsb9938's kernel didn't help, even with overclocking (though the kernel did actually work).

Thanks to dsb9938 for the development and also for responding so quickly both on IRC and on these forums with the goo.im link was down.
