Hi fellows!
As some of you have seen in Humberto's P1000L/N Gingerbread thread, I'm building a Gingerbread kernel for these devices.
At the beginning, I thought that I'll just port the Overcome kernel to ours devices and I'll never touch on these files again.
But it turns out that it shouldn't be like that. So, to avoid mess with Humberto's thread, I decided to begin a new one.
Here are the current features of my Kernel, which was initially based on Overcome v3.3.1 kernel:
Main Features of latest stable version (20111029)
Kernel 2.6.35.14
Lagfree governor
Smoothass governor
SmartassV2 governor
BFQ IO scheduler version 2 (revision 1)
Conservative, Ondemand, Performance, Powersave, and Userspace governors from 3.1 kernel tree
Built with 2011.03 toolchain
TV SUPPORT (P1000L only)! (it is available if you flash the recently leaked P1000L gingerbread version: http://forum.xda-developers.com/showpost.php?p=17993125&postcount=355)
10-points multitouch driver
File Systems support: RFS/EXT{2,3,4}
Overclock (@1.6GHz) with these steps: 1.6ghz, 1.5ghz, 1.4ghz, 1.3ghz, 1.2ghz, 1ghz, 800mhz, 600mhz, 400mhz, 200mhz, 100mhz
Undervoltage
Touchscreen Undervolted (from 3.3V to 2.1V)
RAM Undervolted (1.8V to 1.7V)
ADC Unvervolted (3.3V to 3.0V)
Voodoo Sound v10
Built in CIFS/TUN/SlowWork support
Stochastic Fair Blue (SFB) Network Scheduler
V(R) Schedule, but SIO set as default.
Autogroup Scheduler
Asynchronous I/O Enabled (AIO)

This is an UNSTABLE kernel, and we are expecting some functionality breakage! Again, some patches that I applied hasn't been tested in any other GT kernel yet...
Use tiny-shmem instead of full shmem implementation
Tiny shmem is an alternative implementation of shmem filesystem that uses RAMFS code instead TMPFS. It should be suitable for small system which doesn't have swap and doesn't need the advanced features that the full implementation has, e.g. the size limit control. By removing these unnecessary features, tiny-shmem should increase the performance.
For Galaxy TAB, swap isn't used and size limit isn't a necessary feature, so tiny-shmem should work well.
But it is just my guess! I really need help to test it...
Many performance tweaks in low killer memory
It should make memory manager better.
Enable CPU-supported unaligned access
Enable the option CONFIG_ALLOW_CPU_ALIGNMENT, since the Galaxy Tab P1000 has a Cortex-A8 based CPU.
Advanced ARM processors, such as the Cortex series and ARMv7-based CPUS are capable of performing unaligned accesses for many types of memory accesses. Typically, using a cpu-based alignment fixup is faster than doing such a fixup in software. For best performance on advanced CPUs.
20111029 STABLE (http://www.mediafire.com/?9ug8n71vgc5ik7u)
This version was made stable on 05-Nov-2011, since there weren't any bug reports.
md5sum zImage
0fce8943c0b950c05e0d5163cf662460 zImage
At this point, I decided to add more aggressive updates in my kernel.
I have searched the others gingerbread kernels for devices like GT to verify if there is anything that can be used here.
Conclusion: I found tons of things that can make our experience and overall stability better.
For this first time, I just added some of them and I'm willing you to test it and report anything weird that you find.
Update initramfs from Humberto's kernel
Update initramfs from Humberto's kernel. It now has:
- CwM recovery v5.1.2.6
- New su binary v3.0
Thanks to Humberos
Erase memory pages when they are freed
Should improve memory handle.
Thanks to renaudallard.
net: wireless: bcm4329: compile wifi driver with Os flag
Add -Os GCC optimization flag to compile wifi driver.
This approach was used in Galaxy S kernel, so it should be fine
in GT-P1000 also.
Thanks to zachariasmaladroit.
ashmem improvements
ashmem: fix deadlock when system is low on memory
ashmem: Add cache flush routines to ashmem (zachariasmaladroit)
cpuidle: menu: fixed wrapping timers at 4.294 seconds
If everything goes fine, I'm planning to add more and more patches at each update.
This way, it would be much easier to track possible regressions.
20111026 (http://www.mediafire.com/?7fv630kp5bu15ev)
Using 2011.03 toolchain again
It turns out that the problems regarding random reboots with 2011.03 toolchain is being caused by samsung modemctl driver. For some reason, it isn't compatible with the newer toolchain, so the solution was avoid the driver building and use a binary version that was built with 2009q03 toolchain.
After this, the new kernel built with 2011.03 toolchain doesn't appear to have the random reboots and problems of the old version.
Thanks to alterbridge86 and chib_cr!
20111025 (http://www.mediafire.com/?931h2ev795faztf)
Revert to 2009q3 toolchain
When the kernel was built with 2011.03 toolchain, some users are having random reboots, e.g. when the USB was plugged the TAB rebooted.
Thanks chib_cr!
20111024 (http://www.mediafire.com/?o8be3gs8dfb609u)
I want to thanks alterbridge86 and the Overcome project. Basically, every change was taken from his tree.
Tweak IO schedulers for flash based devices
Should bring some improvements.
ARM: dma-mapping: free allocated page if unable to map (Russell King)
Should kill some process getting stuck and holding the CPU from entering deep sleep, which result in battery drain.
Update smartass governor to version 2 (erasmux)
New version of smartass governor.
Tweak touchscreen sensitivity
Touchscreen sensitivity is improved.
Add compatibility for 2011.03 toolchain
This kernel is being built with 2011.03 toolchain, which should bring some improvements.
Update BFQ IO scheduler to version 2 (revision 1)
Thanks to koxudaxi
20111006 (http://www.mediafire.com/?ahqucc9h5vwgo8j)
Don't check module magic (by Koxudaxi)
This fix some boot loop issues after build the kernel under certain conditions.
Set Kernel version to 2.6.35.14
It turns out that Overcome kernel has already applied all kernel's patches up to 2.6.35.14, so the correct version was set in Makefile.
20111005 (http://www.mediafire.com/?zm5t2w82feqtjuy)
Change RAM voltage from 1.8V to 1.7V
Fix BLN
Although, it still has issues.
Change ADC voltage from 3.3V to 3.0V
Change LCD voltage from 3.3V to 2.1V
10-points multitouch driver
samsung_modemctl is being built now
Overcome kernel is using a pre-built samsung_modemctl driver, because it is avoiding kernel to be built correctly. Here, this issue doesn't happen, so this change was reverted.
20110923 (http://www.mediafire.com/?2e0565sc1sgqmqr)
Update governors set from 3.1 kernel tree
The following governors were updated using Linux 3.1 kernel
tree:
Conservative
Ondemand
Performance
Powersave
Userspace
20110916 (http://www.mediafire.com/?98y1xe2hhu1mrtr)

Tell me what do you think (remember it is a Gingerbread kernel for P1000L/N devices!).
I'm looking for feedback, specially about the new governors...
Works great!
Can't set clock to 1600 Mhz (freezes), but at 1500Mhz it scores 2505 on Quadrant!!
So far smoothass working well...
Tested for about 10 min, so can't tell you much...
BTW: I',m running stock 2.3.3

If you have a P1000L/N tab with Gingerbread, you just need to restart it in download mode, unzip the file, and flash with heimdall:
heimdall flash --kernel zImage
But BE CAREFUL, if you don't know what you are doing, you can brick your tab!
ok thanks.
Just for your information, I have just build a kernel with swap support.
To test it, I created a swap partition on my sdcard.
It is working. Although, I haven't seen any improvements...
When I open too many programs (like 8), android memory manager still force-kill the apps, while I'm expecting that the programs should be transfer to swap memory and, just when it is full, that a program should be force killed.
Well, if anyone wants, I can upload a kernel with swap support, but, at this time, I think it is useless...

I tried to find out the different models and how they equate to one another but Google sends me to everything but which is which model. I have according to my devices "about" a GT-P1000. But, how do I know which model is the L or N? Just to give you more info, I am using the T-Mobile flavor with the modem swap program with Kratos currently flashed.
Hi fellow,
P1000L/N are latin model, if you are using Overcome Kratos with default kernel, you probably have a P1000 device and my kernel isn't compatible.
But you can check it under configurations / about ... (the last menu option), it should have as model number GT-P1000.
Thanks,
Ronan
Hi fellows!!

A leaked GB version for L/N or just L?
If it has TV support I think it is for the L version. But which is the GB version? 2.3.3, 2.3.4 or 2.3.5?
If ti is something better than 2.3.4 I'll try it on my P1000N.

This KERNEL from m-deejay will help u
how
hi again howe do i flash the kernel only ... just new in this my first flash so pleas help med
why
Included kernel details:
New kernel: 2.6.35.14 (under-volted & tweaked)
CPU up to 1.61 GHz (1.15 GHz by default) - controlled automatically by built it O/C Daemon. How to use O/C Daemon?
If you want to control CPU manually, you would need SetCPU from here: SetCPU
In SetCPU remember to check "Set on Boot", but using O/C Daemon gives much better performance and battery life
Many CPU governors (SmartAss, Ondemand, Performance, Conservative, UserSpace)
GPU+ patch (Improved 2D & 3D Graphics performance - Thanks to -snq)
V(R) I/O as default scheduler
SLQB Memory Management
CIFS, TUN & UTF8 support
LZMA compression
Wi-Fi module improved drivers
2-way recording patch ( why is this there ????????? is it not working )
Possibility to change VDD levels dynamically - check question 21 in FAQ
Code cleaned up with custom voltages, tweaks & many more!
You can find custom kernels here
Since your on stock, you need root access ti install 2wrec. Root it first with ace advance kit...
Then install custom rom with 2wrec kernel.
The question marks are there as the app that does the recording is suspected to cause battery drain. Also becareful once you get the app as in someplaces of the world if you so not tell them you are recording them not only can you be sued but could face stiffer penaltys

I don't do anything in particular to prevent it. I have the stock LK4 Samsung boot logo. Give it a try. Worse that happens is you lose the boot animation and have to go back to stock.

That's because custom boot animation support is part of the kernel but a few lines have to be added to init.rc and init.qcom.rc in the ramdisk in order to get custom animations to work. I've personally had a really difficult time trying to crack it in the JB kernel...the process is different and not as easy as it was in with ICS kernel releases.
Also I'm very interested in this kernel. I've been looking for something basic. Stock with undervolting and a nice governor like intellidemand to go with it. Thanks so much for this.

Sorry for the double post but what would cause setcpu and voltage control to not give you the option to set voltages, where system tuner let's you do it just fine?
I should also add that everything seems wonderful so far.

Update posted. You no longer need to rename system binaries. I just disable them in the ramdisk.

I've tested all the kernel available on marsmallow (D855) and neither satisfy me ....
If someone can create kernel just with some future as:
- fasthotplug (William kernel, Xperia SP, by pec0ra) or show1984 msm_mpdecision.
- UV control.
- OC GPU and CPU.
- Lionheart, SmartassV2 or SmartassH3 governor.
If someone success to create a kernel with all this future and stably it should be really great !
Sorry for my poor english ^^
Don't ask for gsi ROMs working or fully working twrp unless someone develops a custom kernel for mi 8 se só lets help each other and make a custom kernel for mi 8 se
asking someone to build something "As Soon As Possible" ???
Xiaomi just released kernel for Android P:
https://github.com/MiCode/Xiaomi_Kernel_OpenSource/tree/grus-p-oss/
I've tried to compile that source and everything working good now (unlike previous Android O kernel which 2nd camera not working in Portrait mode and sound is broken when turn off display). Here is my compile kernel with a lot tweaks now can be change in EX Kernel Manager (KCAL, fsync, iosched, block wakelocks...) to gain more battery and performance, I've only tested with MiuiPro 9.3.1 and EU 9.3.1 but this kernel should work with all MIUI roms based on Android 9.0.
Kernel features:
Compiled with GCC 8.2.1, mtune=cortex-a75.cortex-a55 (best for Kyro 385 arch.)
KCAL Advanced Color Control
KLAPSE
Min Backlight Control
Fsync Control
Vibration Control
CRC Check Disabled
Reduced latency 6ms to 5ms
Disabled Gentle Fair Sleepers
Power Efficient Workqueues
LZ4 Compression Algorithm (default)
Westwood TCP Algorithm (default)
Boeffla wakelock blocker
More I/O scheduler: fiops, sio, mapple, zen, tripndroid, anxiety (default).
kgsl: Removed POPP / Wake GPU upon receiving an ioctl rather than upon touch input.
Added devfreq boost driver and cpu input boost driver.
Added more buffer to enhance EIS.
CONFIG_HZ=300
Workqueue powersaving.
Enable deepest state for CPU cluster.
Boost to the max for 1s whenever the top app changes (improves app launch speeds).
Zipped up with AnyKernel2.
Download link v1.15 (last update 04/03/2019):

Thanks for Your effort keep updating the kernel everything works in 9.3.7 you can add features to kernel
Sorry for asking , this kernel is for Mi 8 se or Mi 9 se?

For Mi8 SE. Xiaomi use same source for both Mi8 SE and Mi9 SE but this kernel use Mi8 SE config to build source.

Thanks for your awesome work for our device.
I tried it on Xiaomi.eu 10.2.2 stable version, it didn't boot. After restoring boot partition phone boots but your kernel is gone.
Tried with magisk 18.2 installed, after that I uninstalled magisk and tried again but no luck

You can try with MiuiPro 9.3.1 in this link (it's based on Miui China developer version with a lot tweak, enhancement... more than Xiaomi.eu, also it's paid version).

I'm using MiuiPro as my daily driver atm so I can't switch to other rom to test my kernel.
Tried with miui eu 9.3.1 booted fine
You can add performance tweaks like overclock CPU and GPU update to 4.9.161 or later battery tweaks and make it compatible with aosp ROMs thanks
Installed on masik 2.6 (9.2.28) didn't try any tweaks on ex kernel. Kcal is not working with savoca.apk but phone is working smoothly so far

I've tried overclock GPU from 504Mhz to 610Mhz but phone insta freeze after boot completed, I think overclock not available for SDM710 (maybe they use efuse lock to prevent clock going higher than default, as SDM710 actually a downclock version of SDM845). For kernel upstream, 95% changes will not affect any performance or bring new feature for Qualcomm ARM64 cpu.

savoca is too old (last update from 2015), you must use EX kernel manager to change KCAL (in Graphics -> Advanced color control).
Will this work on gsi treble img thanks
You should do a group on telegram where anyone can contribute with ideas to the kernel and show updates on the group

I just let you know. Last time when i tried miui pro 9.3.1, wifi didn't work on my device. Does it work with your kernel?
Thanks

Maybe you downloaded a corrupt zip file of MiuiPro 9.3.1 rom (which cause Error 7 when flashing rom in TWRP), that will make wifi doesn't work. I got that corrupt file too and I've fixed that corrupt file and reuploaded again to GDrive in above link.
I downloaded from your link.
It works like a charm, thanks :good:
good ！ When is the complete AOSP package?
does it works for pe？
Updated new kernel date 03/13 with KLAPSE live display module added, you can use EX Kernel Manager 4.08 to control KLAPSE settings,
