I have been making ROMs & kernel for the Galaxy S phone for quite some time.
I have started to port my kernel to the Galaxy Tab.

Changelog:

-See github for details
-On my tab, it gave a 20% boost in Quadrant score

-ROW scheduler (tweaked, default scheduler)
-many improvements to IO schedulers in general
-GPU overclock (based on A1 kernel)
-1200-1400-1600MHz OC steps (based on A1 kernel)
-150MHz underclock (based on A1 kernel)
-Voltage adjustment (based on A1 kernel)
-Improve memcopy/memmove
-Improve the performance of memcpy and memmove
-Kill task closest in size to memory needed to free
-LOAD_FREQ (4*HZ+61) avoids loadavg Moire
-Entropy tweaks: http://lwn.net/Articles/489734/
-arm/crypto: Add optimized AES and SHA1 routines
-build WWAN, NLS & NTFS modules
-CIFS included in kernel
-Removed MMC_CAP_ERASE (so safe for wiping)
-Improvements to RWSEM
-Improvements to binder algorithm
-Improvements to tmpfs
-Improvements to spinlock
-Added frandom

You can only flash this if:
-You have a Galaxy Tab 10.1 wifi (also know as GT-P7510 or p4wifi)
-Stock version: you run a ICS stock rom (so not an AOSP/AOKP/CM-based ROM) - an stock-based ROM such as Infamous is also fine!

I have no plans to port this to other ROMs/devices, as I want to test everything myself and I only own an P7510 running Infamous v2.2. Feel free to port yourself, source can be found through the link given above.

Hi,

Thanks for this!

Does this by any chance gets rid of YouTube HD lag/stutter?

I don't get stutter on YouTube HD...

There are some tweaks in Infamous Tab 2.2 to help with video streaming. Perhaps switch to that ROM if you're not using it now and flash this kernel over top of it to give that combination a try?

At least I am on Infamous, so I can't say whether the fact that YouTube HD works fine is due to infamous or due to the kernel :highfive:

Hmm. for real? I want to be at ICS but because of Youtube, I am downgraded to honeycomb. So I don't know what has been changed on Infamous, but I might give it a try! Hope it actually makes Youtube HD smooth, because everyone tests with different videos, some people always say that they don't have Youtube HD lag, but some people test with a video that they always had lag, and other custom roms have the same problem so they say they always have youtube hd problem.

Anyway, I'll test both Infamous and this kernel in the weekend.

Again, thanks both of you guys!

If you send me the link to a movie that had issues for you in they past, I would be happy to test it for you.

I just have to say I reverted to 2.2 from IOSP testing to run this kernel. It is a thing of beauty!! Really well done K.

Sure thanks for that!

Here is a video of a music concert that I always use to test: http://www.youtube.com/watch?v=QSb5ZSnn2qs

I also posted this for others to test on a Q&A section for Galaxy Tab YouTube Lab thread, and while a lot of people had the same problem and had the lag and stutter problem, it was very weird that some people did not have any issue. So I'm curious what you will say.

Thanks!

Same here..

Sent from my GT-P7510 using XDA Premium HD app

Its hit or miss with me...most of the time things are fine but sometimes I have a stutter or two. It has been reported on other stock ICS ROM threads that this was a miss on Samsung's part, we can only do so much to help the problem. There are tweaks in Infamous 2.2 as I mentioned, but they most likely won't compensate for a larger issue.

I have been making ROMs & kernel for the Galaxy S phone for quite some time. I have also worked on porting this (CM10.1-based) ROM to the Galaxy tab. I do think, however, that CM10.1 is not worth it (for me!), stock ICS is faster/smoother. And I like the floating apps in the status bar.

I have started to port my kernel to the Galaxy Tab.

Features:
-Based on Samsung ICS update 2 sources
-Voodoo sound
-Enable USB charging
-XZ compression of kernel
-SIO scheduler
-BFQv5 scheduler (with upstream improvements)
-ROW scheduler (tweaked, default scheduler)
-many improvements to IO schedulers in general
-GPU overclock (based on A1 kernel)
-1200-1400-1600MHz OC steps (based on A1 kernel)
-150MHz underclock (based on A1 kernel)
-Voltage adjustment (based on A1 kernel)
-Improve memcopy/memmove
-Improve the performance of memcpy and memmove
-Kill task closest in size to memory needed to free
-LOAD_FREQ (4*HZ+61) avoids loadavg Moire
-Entropy tweaks: http://lwn.net/Articles/489734/
-arm/crypto: Add optimized AES and SHA1 routines
-build WWAN, NLS & NTFS modules
-CIFS included in kernel
-Removed MMC_CAP_ERASE (so safe for wiping)

Cool , so you have started supporting another of my devices eh. But I have the P7500 3G model , any chance you will make a version for that ?

Also how do you control GPU OC, which app do we need.

You can compile it yourself, just get my code from github and compile it with an appropriate defconfig.

I only compile for devices I own or have direct access to, because I only want to upload things to xda I have personally tested...that is my philosophy :)

GPU OC is one fixed setting, nothing can be changed.

How much is the GPU stock clock and OC clock.

I will try to compile for P7500 next month then ...

BTW can I flash the P7510 version for testing atleast , maybe I would lose connectivity ?
I read that P7500 users could flash P7510 ROMs but modem would be unavailable

    I have recently spend quite some time making a kernel for Infamous AOKP. I have now ported all these code improvements to the stock kernel as well.

    Changelog 1.4:
    Updated stock kernel based on work I have done for infamous ROM:
    -Improvements to RWSEM
    -Improvements to binder algorithm
    -Improvements to tmpfs
    -Improvements to spinlock
    -Added frandom

    OC/UV is all taken 1:1 from AAccount.

    Look at this commit:
    https://github.com/kasperhettinga/p4wifi_stock/commit/29e8db7350bb605d7808f82dabe1e3f7912a1521
    and then this file:
    arch/arm/mach-tegra/tegra2_clocks.c
    line 2519/2681 show the increase in GPU clock from 300 to 400MHz

    Small update to 1.3

    Additions:
    -SmartAssV2 governor
    -Lulzactive governor
    -Wheatley governor
    -Lionheart governor
    -Aggresive governor

    BTW, I use NSTools to change kernel settings :)

    After a very long time, I gave stock ICS another try. I needed to Skype a lot this week, which is not possible with my Omni KK4.4 build. So I decided to go back to stock ICS for the time being. This also felt like the right moment to update the kernel (after more than 6 months of standstill).
