[KERNEL][3.0.30] Matt's kernel v0.8 - 29/04/2012

GuestK00248 · Apr 29, 2012

Hi!

This is my first kernel for Nexus S. It is based on _thalamus 3.0.29_r1 kernel.
Matt's kernel don't have OC, LiveOC or similar features.

Original changelog/features from _thalamus:
*Second stable release based on AOSP 3.0.8 source, merged up to 3.0.29 from mainline kernel.org
*PM Fast for wifi
*Deadline I/O scheduler tweaked for flash for lowest I/O latencies
*Ondemand governor tweaked to sample less at higher frequencies to reduce overhead
*Config: CFS CPU scheduler, Deadline I/O scheduler, Ondemand CPU governor, SLUB allocator, Tiny Preempt RCU, Tun/Tap, IP advanced routing and CIFS built in
*Various compiler warnings and section mismatches fixed
*Disabled a stack of debug options resulting in a slightly faster kernel.
*Built with latest Linaro toolchain (GCC 4.6-2012.03)

* Changelog/features for v0.8 (29/04/2012):

Stock Display Freq
Added BLD & BLN
block: limit default readahead size for small devices
BLD Enabled (3000ms)
BLN Enabled (I need test)
KSM tweaked
Added modified liblights for BLN

Changelog/features for v0.6 (29/04/2012):

Optimized compiler flags
Increased HZ to 1000
Added optimized CRC32 algorithm
Increased default readahead value to 1024KB

Changelog/features for v0.5 (29/04/2012):

Gzip
Enabled KSM for page merging
Disabled "Debug Filesystem"
Disabled "Kernel debugging"
Patched from 3.0.29 to 3.0.30
65FPs panel
Little tweak for Deadline
Added ARM RWSEM algorithm
Added SLQB memory allocator
Build with 4.6-2012.04 Linaro

I have high performance but I don't know yet about battery drain.
Remember to wipe Dalvik cache.

only thing i'm missing is bln, i'd really love to give this a try if you could incorporate this

GuestK00248 · Apr 29, 2012

I'll implement soon BLN, I need it.

For another things, I don't know. For now I need tests for this kernel.

Hope!

Welcome to the Nexus S community.

I`ve used your kernel for a couple of hours now. Like the other folks, I miss also BLN, and also Voodoo sound/colors.

Besides, the only downside till now has was the laggy 3D performance in games. I thought that it was only the game, but tested 3d in Quadrant Advance, and it was still the case.

Overall, your Kernel is snappy and stable-no random reboots till now. I`ll be waiting impatiently for your next release

GuestK00248 · Apr 29, 2012

v0.8 released.
Changelog in first post.

using root explorer, go to /system/lib/egl/ and delete the libGLES_android.so file. reboot, then try quadrant again. any difference?
