[KERNEL][Sony JB 4.3][26.04.15] Williams kernel v9.1

what about external speaker (in back, not in front)? Can FS increase sound of that speaker?
They are the only main speakers,and yes when you adjust the speaker gain you are setting the volume for the speakers in the back.
U mnie dopiero ze dwa razy wystąpił, a używam dopiero tydzień.
I had 2 random reboots in this week, but this is my first week with this kernel.
Bo to zależy od używania i ustawień. Mój się włącza, chwila mija, klikam aplikacje i reboot.
You can use this kernel with CM11 for LBL
But you need to unlock your BL to install this kernel.
OpenCL is something to use in an app, not in a kernel.
But be sure that if someday I create an app I'll parallelize it as good as I can
You should but you don't have to.
Msm_mpdecision just stops if it sees that something else (qcom mpdecision for example) is already managing the cpu.
Now disabling qcom mpdecision in trickster mod lets you use msm_mpdecision (from show-p) and this one has advantages like battery life.
Keeping the two of them might also make your phone "fade and reboot" because of some bug.
@pec0ra any news for implement of Dynamic dirty page writebacks in kernel ? (http://xdaforums.com/showpost.php?p=42354290&postcount=2)
(Very good work with v6 and v7 !)

Could someone please give me detailed installing instructions?

TBH this is the best kernel for xsp. thanks again to save up our age old device :highfive:
i am using v7 with stock 207 . but from performance control or fauxclock i can see minimum is 281 but in pool i can see it says :
Poll: Did the 270 MHz frequency step increase your battery life ?
so does it mean there is 270 Mhz also ?

What versions of recovery are included in this kernel? Is it CWM 6.0.47? And what's the version for TWRP?

There was a 270 Mhz step but it isn't there anymore. The poll is quite old now. I wanted to remove it but I don't think it's possible without admin help.

You can find it there
Q : Where does the name come from ?

New update : Williams kernel v8
Changelog :
- Set qcom mpdecision as default hotplug (No need to rename it anymore unless you want to use another hotplug )
- Remove msm_mpdecision
- Add fast hotplug
- Increase 1.8GHz step frequency for better stability
- Add FOTA recovery support (Volume down; needs testing)
From now on, you won't need anymore to deactivate mpdecision before flashing the kernel. It is now set as the default hotplug. You only need to deactivate it when you activate another hotplug (for example if you want to try fast hotplug) but if you use the app Pimp my Z1, it will do it for you !
About fast hotplug :
Fast hotplug is a hotplug I wrote myself. You can find more information there

New update : Williams kernel v9
Changelog :
- Fixed frequency table
- Add 1944 MHz frequency step
I have some good news ! I finally found what was causing the reboots with my kernel
All the frequencies were in fact 108 MHz higher than they appeared to be. The voltages were then not high enough for the real frequency and it was causing reboots.
Note that the 1944 MHz step might still be unstable on some phones and has the tendency to overheat your phone so be careful when playing with it ! Don't be surprised if your phone shuts down because of overheat if you are using it.

Minor update : Williams kernel v2.2
Changelog :
- Changed illumination at splash screen
- Fixes for compatibility with linaro GCC 4.9.1 toolchain

- Use xz compression
This build should be faster than the previous one due to the new toolchain used to compile it and some compilation optimization.
If you want to play with your leds, take a look at the script I created. It has some easy to use functions. You can find it here. Just run it from terminal or script manager with root permission and don't hesitate to edit it and reuse it.
