[KERNEL][T210/T210R/T211] blackhawk kernel 2.1

First unofficial kernel for Galaxy Tab 3 Marvell PXA988, reported works on T210 and T210R variant (T210 version) and T211 (T211 version)
Kernel source: https://github.com/kumajaya/android_kernel_samsung_lt02
Kernel modules source: https://github.com/kumajaya/android_kernel_samsung_lt02_modules
Features:
Based on my kernel commits and modules commits:
Open source exFAT filesystem driver from Samsung OSRC
Configurable touchscreen orientation, so we can use this kernel as touch based recovery kernel
Override 1MB ramdisk size limitation + xz compressed ramdisk. CWM recovery need > 2MB ramdisk, no blackhawk = no CWM/CWM based recovery
Zram support. Update LZO compression library to upstream version, optimized for arm processor
Linaro gcc compiler. Update Marvell P4JB CPU init routines for linaro
Hardcoded ION carveout memory. Old version bootloader will boot this kernel without blank pop up bug!
Using the latest T210R MJ1 GPU, WiFi, bluetooth, and T211 MI3 telephony drivers. This kernel always bring the appropriate kernel modules inside /system/lib/modules to prevent kernel modules incompatibility issue
Single source for all T21x variants, different kernel config, different flashable zip for T211
Integrated self compiled busybox, fstrim applet included for a lag fix
Auto root, no need to flash any root solution
Init scripts support (/system/etc/init.d, /data/local/userinit.d, and /data/local/userinit.sh)
Kernel module loader template /system/etc/init.d/02modules
Post boot template /system/etc/init.post_boot.sh
Zram manager, over "adb shell" or Terminal Emulator:
Code:
su
setprop persist.service.zram 25
to set 25% memory size zram, persistent.
Code:
su
setprop persist.service.zram 0
to disable zram. Needs reboot.

Special Thanks:
@gr8nole, @hkjr, @klopeck
Note:
I don't own this tablet myself. This is the side result of my work and @gr8nole, making a working kernel for recovery. For better development support, please consider donating.
Both kernel and kernel modules source on my github account already, feel free to fork it. "Don't reinvent the wheel, unless you plan on learning more about wheels."
Flash at your own risk!

Flashed 1.2 and System Tuner reports that both cores are maxed out (1.2ghz) and do not scale back down. I gave it a few minutes after restart and they remained maxed out. (Wifi off, nothing syncing).
Flashed back to 1.1 and everything looks normal again.
Not sure how reliable System Tuner is.
EDIT: Nevermind...flashed 1.2 again (wiped cache and dalvik) and all is well. Both cores scaling properly now.

I'm seeing similar behavior.
does system tuner allow for adjusting settings? i'm using kernel tuner - http://forum.xda-developers.com/showthread.php?t=1719934
& it was showing the 'min' value for both cores was set to 1205Mhz, the same as the max.
i've backed it down to 312Mhz on both cores & all seems to be good.

I don't think System Tuner does a very good job reporting dual-core devices, but I haven't found a better app yet (still looking).

Trickster MOD much simpler.

running great. Thanks man..

Looks like the IR is not working. I'm going to flash back to stock to make sure it works correctly with that.
Edit: IR blaster works on stock but not on this kernel (v1.2).
Let me know if you need any files from me to get a possible fix.

Does this kernel have more cpu governor or/and I/O governor?
EDIT: Oh nevermind i checked your source.

Testing
Thanks for the kernel!! I'm testing it now and it feels good so far
m.

report
After rebooting the device the subscription to the Wi-Fi network get lost, means I have to reenter the password after every reboot. I don't know if it's the kernel like it is or because I changed the TCP congestion fromm cubic to highspeed. I don't have any experience with this feature. I could change back to cubic and check if the network subscription sticks... .

Anyway to flash back to Stock Kernel?

Would a boot.img backup in this case suffice? I haven't flashed the kernel yet but a boot image backup would contain the old kernel as well. The question is mostly if there are any other modifications that are being done.

If you don't have the zip file, I would say, you could restore the boot and system partition from your backup, this should bring back the backuped kernel.

All other partitions are simply not supported

Kernel works great so far. No issues and performance feels good.
What's the best way to switch between SELinux permissive and enforcing on this kernel should one want to experiment with that? Some solutions don't seem to like KNOX but it should be disabled on the kernel, too, right? I'm still struggling to get Magisk Hide working so I'm feeling experimentative.

I guess im first to comment here,what an honour.
Thanks for showing love to our tablets. Now what remains is some nice Rom to compliment the kernel...

Well done,will give it a try for sure.
Thanks for helping the community!

this kernel shows a boost in performance on the t700 compared to stock kernel....nice!

I noticed some minor issues with the wifi. It takes a lot more to recognize the signal in the switching from off to on. Also it forgets known connections. Did I do anything worng?

Thanks for great work !
When installing kernel on 705 there is message that 805 kernel was installed (I know its a typo).
Testing.
Geekbench scores:
Iron: 564/1593
Stock: 811/1993
This is strange, it seems that your kernel is slower, It might be something related to thermal throttling so im not sure...

Posted in the adoptable storage thread but thought it prudent to post here too. The adoptable storage patch with this kernel would result in saying the sd card is corrupt (3 different cards) by using the stock kernel, formatting the card as internal it worked. Flashed this kernel again and it is still working

That score can differe from each time to time depending on temperature of soc and outside

I WANT TO ASK YOU A QUESTION. I HAVE A SAMSUNG GALAXY M20. I TRIED TO INSTALL GOOD LOCK FEATURES MANUALLY. BUT THOSE APK's CAN'T BE INSTALLED. CAN YOU TRIED THAT WITH M20 AND CAN YOU TELL ME WHAT IS THE REALY REASON FOR THAT? AND IF SYSTEM HAS BLOCKING GOOD LOCK APK's, CAN YOU TELL ME ANOTHER WAY TO INSTALL GOOD LOCK APK's.

External wifi adapter
Does this kernal support external wifi adapter??

Hi harry,
After I install the Kernal, everytime I bootup the phone I'm greeted by your device has internal error or something like that.
Is there any fix for that?

Ignore those warnings, this warnings may be due to some missing apps in rom.

I tried comparing your kernel and stock. I see a completely different network. I mean, making phone calls through facebook or LINE app is very unstable. I tried comparing so I just told you so.

thannks:good:

I am STUCK with SeLinux FORCED to enforcing after upgrade to M205FDDU8CUI1 ( my phone is SM-M205FZBDINS) . I want to make it
temp permissive || change seLinux pOlicy to permit a mounting operation to happen || if possible correct my mounting approach.
On the 3rd op - I tried everything but NOTHING works. FYI - I want to bind mount WhatsApp folder to its own ext4 partition . Wtth permissive it was poss. NOT so with enforcing. Tried bindfs all options NOT working. since u see t o no el more kernel selinux I asked u & XDA here . Do you know how to get this done ?

will it work after upgrade to latest ROM M205FDDU8CUI1. Previous kernel caused boot loop. SeLinux ? 0 or 1 Magisk rooted Y / N ? Samnsung Crapware Detox ? Y / N ? Volte Y / N THANKS buddy for your effort

Hi, this kernel is for AOSP Custom Roms only that you can found on official lineage os download site. i will release for OneUI version soon!

stuck @ androidlogo x 10 times...once started --> internal error --> immediately reboo & then stuck again t. @gianonceu How do I compile from source. For this stock ROM if I have source should I just compile just boot ( after modifying ) or entire ROM ?

hi, i already did overclocking the kernel and did a gaming test with oc kernel. i wont do it again because of how hot and unstable the phone is when it throttles. because i will be the one who will blame if the phone is broken because of overclocking, i hope you understand.

It works thanks!.

Howdy PL also add ext4 on micro-sd card mounting via vold . ALL custom ROM - GSI Lineage etc support it. i.e. support ext4 FS for mounting . Then I can flip SeLinux 1 . I have to run it 0 cos of SeLinux Policy issues. Can you PL point me to some online guide of how to compile new SeLinux Policy rules ?
