[Kernel]HTC GB[2.6.35.13](v0.0.9)OC~2.03GHz/UV/BFS/BFQ/SLQB/SmartAss/MinMax[Jul-13]

NOTICE: This is ONLY COMPATIBLE with New HTC Gingerbread Sense Leaks!!!!
(Including: Orange Glacier 2.0, Royal Panache, Evil Dee's MyTGB, Virtuous Fusion, Elite Sense, Uber Sense, Deck Sense, ALL of Rafy's GB Sense Ports )
Just a statement regarding kernel source: The Kernel Source is of course covered under GPL version 2. Free software does NOT mean no work or time was spent working on it. I have donated a large sum of my free time to hack this kernel. If you use my modified kernel source in its entirety, I kindly ask you to send me a github pull request or PM whenever you find bugs or think you can help improve my kernel hack further. This way the entire community will truly benefit from the spirit of open source. Thank you

All GB CM7/AOSP ROMs should use my GB CM7 / AOSP Kernel
All Froyo AOSP ROMs should use my Froyo AOSP Kernel
All Froyo Sense ROMs should use my Froyo Sense Kernel
Hi XDA members and fellow MT4G users:
This is my Fifth kernel hack. I want to thank Cyanogen, Zinx, Erasmux, and several others I cannot recall for inspiring me to venture into this unfamiliar territory for me.
What is a Kernel? The Kernel is the Foundation in which everything else builds upon in any software system.
[Car Analogy]: Kernel is like the Engine, Electrical system and the Transmission to a car. The Library, Framework and the Apps [AKA ROM] are the body frame and the rest of the Car.
​
THIS KERNEL is BASED ON HTC Source Code. So it is COMPATIBLE ONLY WITH HTC Gingerbread Sense Builds.
Please DO NOT use any task killers, they DO NOT improve performance nor battery life. They INTERFERE with your phone's stability (more crashes) and App compatibilities (Forced Close).
MinMax Governor (Battery Saver)
This governor will try to minimize the frequency jumps/changes which cause voltage spikes/changes which supposedly drains more battery life... Supposedly designed to work with SetCPU... so give it a whirl...
SmartAss Governor (Balanced)
This governor has a built-in "profile" similar to SetCPU, so screen off will use lower clock rate thus conserve more battery, but it also has a fast wake up feature so that user interaction will not see the lag when switching from Sleep to Wake state.... (So SetCPU Profiles are sorta redundant when using this governor, you can still use SetCPU to OC to higher than default Clock frequency).
Interactive Governor (Performance)
This governor is designed to put more priority to User Interface (UI aka Apps) tasks, therefore appears more responsive then the traditional OnDemand governor. So if you want the smoothest UI interaction, this governor is for you...
Brain F*ck Scheduler - (BFS)
This scheduler is designed to be simple and speedy tailor specifically for user interface type systems such as desktop/smart phone devices where user interaction is MORE important than serving 1 million web requests (CFS, the default scheduler) at the same time (think of nimble desktop workstations vs large corporate servers).
SLQB - (SLAB allocator with Queue)
This memory allocator is designed for small number of CPUs system (such as desktop or smart phone devices). This allocator is design to be simple and it is optimized for using order-0 pages as much as possible (order-0 pages are the simplest therefore quickest type of memory in a Linux system to allocate). Not all kernels are using SLQB including CM7 main line...
Fair Budget Queue (BFQ I/O scheduler)
This I/O scheduler is an improvement on top of Completely Fair Queue (CFQ). CFQ is fair in terms of time but not in terms of throughput / bandwidth, so BFQ make sure that both time and throughput / bandwidth are balanced across all requests.
Installation Instructions:
Here's a step by step instruction to install this kernel:
( NOTE: If you experienced BOOT LOOPS, Load the First Time Kernel Before Updating to newer kernels)
The File ==> First Time Kernel <==
[ CFS-Smartass ] (Mainline)
The File ==> HTC GB Sense Kernel 0.0.9 CFS Low Voltage <==
The File ==> HTC GB Sense Kernel 0.0.9 CFS Stock Voltage <==
[ BFS-Interactive ] (Enthusiast Edition)
The File ==> Not Available <==
The File ==> Not Available <==
Low Voltage - Under Volt the processor, therefore uses Less Battery, but NOT ALL CHIPS can handle Under Volt.. If you experience instability, try the Stock Voltage Version.
Stock Voltage - Uses the voltage values from ORIGINAL HTC Kernel Source.
There are NO PERFORMANCE DIFFERENCE between the 2 versions!
1. download the above file (via phone directly or to a PC)
2. copy the downloaded zip file to /sdcard/download/
3. Open ROM Manager and select "Reboot into Recovery" and select "OK"
4. Once in recovery, select "wipe cache partition", select "Yes", then select "advanced", then select "Wipe Dalvik Cache", then select "Yes" again. Once finished, click the back button to go back to the main recovery menu. On that menu, select "Install Zip From SDCad", then select "Choose zip from SDCard", then go to /sdcard/download and select the downloaded zip file and let it run its script.
5. Once the script is done, select "reboot system now"
Note: After FLASHING, the first reboot may take longer than usual, please be patient... After the first reboot, it may lag during initial load (let everything finish loading). Once everything is loaded and phone is ready for use, reboot the phone a 2nd time and the lag will be gone and everything should be silky smooth...
NEWS BULLETIN:
Version 0.0.9 is OUT!
1. Fixed MMS while on WiFi calling
2. Adjusted Frequency/Voltage table to allow upto 2.03 GHz
3. Volume Boost for Speakerphone, Handset and Bluetooth
BFS is not very compatible with Sense.... I am dropping BFS unless huge user demand for it..
Please don't hesitate to talk among yourselves and help each other out... The MT4G/XDA community is what inspired me to hack kernels for everyone since everyone here is nice and helpful to each other... Keep helping each other.... Famous proverb: It's better to give than to receive...

[ Android 2.3.4 ROM ]
If you experienced WiFi issue, it means the bcm4329.ko modules was NOT installed properly.
Extract the bcm4329.ko from the same zip file, then
[ with ADB ]
adb push bcm4329.ko /system/lib/modules
[ with Root Exploror ]
1. touch Mount R/W
2. copy bcm4329.ko to /system/lib/modules
3. long press on the bcm4329.ko and select Permissions then check read, write for owner, read for group and read for others, click ok
4. long press again on the bcm4329.ko and select Change Owner, then pick 0-root for owner and pick 0-root for group, click ok
I will investigate to see if I can fix the updater script so this would be done automatically with 2.3.4 ROMs

Are you gonna update your rom or no?? Because you know me miss you...lol

Omg, Jesus Christ you can totally tell the difference with this on CM7. Feels WAYY SMOOTHER and more fluid. FAST!

No wonder I'm having so many sluggishness/lag problems... I wasn't aware the kernel changed with nightly #91.
Apparently everything works with the old kernel, it just runs like poo and is draining the crap out of my battery.
Going to update this now.

Yesss....do your thing Faux!!

Thanks Faux. Much appreciated.

[05-Nov-2011][Kernel][GB][P1000L/N] Ronan's Gingerbread Kernel

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)
Backlight Notifications
Humberos' Initramfs 20111102
Features that needed to be test (I'll appreciate any help):
BLN has problems
I'll appreciate any help or feedback!!

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.​

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!!
I have just tested the recently leaked gingerbread version with my kernel and everything is working flawlessly, including TV!
I'll post more details...

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.

hi could you post de tv app?

Just the TV app won't work. You will need the entire ROM and P1000L model.

No, it is 2.3.3. Basically, it is P1000N version with TV support Nothing more...

Which voltage settings are you guys using ?

Tks, Ronis. Running your kernel for a few days now, all good. Using smoothass, smartass and lagfree, up to 1300 stable, -50mV on 1300 and -25 on the rest.
Cheers.

[Q] pleas help me with 2 way recording

hey would hear about some on who can help me with get 2 way recording to work.
I have flashed for Android 2.3.5 (Gingerbread) - official HTC 3.06.405.1 RUU with HTC Sense 3.0 for HTC Desire HD but can not get it to work please help:-D

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

- ExFAT support for USB OTG / Card readers with large drives
- CIFS network share mounting supported
- Voltage control support (no built in UV, but configurable via apps like SetCPU)
- Optimised kernel libraries
- MSM SoC + Kernel "always-on" logging and debugging disabled to save CPU cycles
- Simple GPU governor
- Ondemand governor tweaked for lower latency speed shift changes
- Internal kernel function fixes (ie, memory leaks, scheduler fixes)
- SIO scheduler (default, noop, cfq and ROW are available)
- high performance, low latency kernel
- compiled with Os flags and neon-vfpv4 FPU enabled
- Westwood+ TCP congestion control
- Built from official LG v10a kernel source
- Lokified during flash
Installation:
- Download .zip and copy to phone
- Reboot to recovery
- Recommended to take full system backup, including EFS partition
- Flash .zip
- Reboot
- 1st reboot may take a little longer than usual
Please do not:
Do not ask for other models to be supported, at this time is D802 only. Other models may follow in the future
Do not ask for extra features. This is to be a stock-compatible replacement kernel only. If LG didn't add it, I probably wont either.
Do not ask for support of other roms, such as CM / AOSP. Im a LG based rom user, if you want a kernel for another type of rom either use one of the available ones we already have or learn to compile your own.

Hi,
Weird, no issue here. You are the first
Maybe a bad download?
EDIT: you are on LG based rom, right?

Agreed. Flashed on Rayglobe 2.6 about 2 hours ago and have been running fine since.

Are you guys running any "set xxx parameter on reboot" type of apps ?
I've been flashing these kernels, as have my esters for nearly a week and have not had any issues with them. The only thing I can think is you have an app which is trying to do something on boot up....
My phone was stock fresh, full wiped, installed my rom, then all the test kernels and 0 issues

I just tested, no bootloop after reboot...
You have not flash something else (a tweak or a mod) or modifying something? Undervolt (too much and set on boot)?
I don't know, maybe wait g.lewarne...

im starting to wonder if there are some subtle phone hardware variations that we are not aware of... ? (and im not talking 16/32gb since kernel is the same according to LGs sources)
either that or its is some app installed trying to do something funky....

@ g.lewarne, exept the CPU binning, I don't know

IKR
I mean, in Wootevers kernel thread there have been similar reports of sporadic non-compatability and although our kernels are quite different, the basic hardware controlling bits are the same. Even if the SoC had different variations, why would the stock LG kernel work for everyone when one built from their own source wont ?
Its either an app, or the sources LG share are not the "real" ones they use, which I have some suspicions about for other reasons
