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!

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 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)

You can only flash this if:
-You have a Galaxy Tab 10.1 wifi (also know as GT-P7510 or p4wifi)
-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.

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

So the base is A1 Kernel. And AAccount oc'ed his kernel up to 400MHz. It hink its the same in this kernel. Stock is 333 or 300MHz. You can check it yourself, but i dont know the folders to look for right now.

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

Look at this commit:
https://github.com/kasperhettinga/p4...e1e3f7912a1521
and then this file:
arch/arm/mach-tegra/tegra2_clocks.c
line 2519/2681 show the increase in GPU clock from 300 to 400MHz
