Frequently asked questions
1.1 Q: I am having an issue, can you help me?
1.1 A: I am not a superstar kernel developer but I will certainly try my best. First, start by reading the release posts, as I may make note of a particular issue. Also search the thread to see if I have discussed it before. If you see nothing, please provide me with a dmesg/last_kmsg and logcat, your ROM/kernel version, and a detailed description of the issue. With that, I'll do my best to assist you.
Code:
adb logcat -d > logcat.txt
adb shell dmesg > dmesg.txt
1.2 Q: Can you add xyz feature?
1.2 A: If you link me the commits or tell me what kernel you had the feature in, I can take a look at them. I will not go digging super hard for commits and I will ignore requests that don't include this information. I won't promise that I will merge every request but I will always take it into consideration.
1.3 Q: How do I control the kernel?
1.3 A: I'd recommend using either @flar2's EX Kernel Manager or @Yoinx's Kernel Adiutor-Mod; both are extremely solid and have given me no issues.
1.4 Q: I am having Wi-Fi disconnects on a 5GHz network, what's up?
1.4 A: Try increasing the wakelock divider on the following sys paths in a terminal emulator (can also be done in EXKM in the Miscellaneous section):
Code:
echo 8 > /sys/module/bcmdhd/parameters/wlrx_divide
echo 8 > /sys/module/bcmdhd/parameters/wlctrl_divide
Thank you to @Buckmarble for pointing this out!
Thanks to:
@REV3NT3CH for showing me what a good developer and kernel looks like
The various developers for their patches (@ak, @Buckmarble, @flar2, @franciscofranco, @frap129, @imoseyon, and @Yank555 to name a few)
@osm0sis for AnyKernel2
@DespairFactor for helping me with some kernel compilation issues and the Linaro source of the toolchains I use
@kantjer for pointing me to Linaro in the first place and being a beta tester along the way!
@malybru for my nifty new signature and thread banner!
All of you guys for viewing the thread
A note about donations
Quite a few people have asked to donate to me in the past and I have turned them down. I am not in this for the money, this is my hobby, something I truly enjoy. If you truly want to donate to something (it is not expected in the slightest), I recommend an entity like the Open Source Initiative, XDA, or any one of the people I have thanked in the OP. Additionally, you are free to copy any and all of my work; the only thing I request is that you not ask for donations as well (though I can't really enforce this lol). Thank you.

Hi,
Thank you Nathan!
I know MultiRom isn't working very good with N yet but still:
Does you kernel have the kexec patch inside please?

Looking at the source, I do believe kexec is present in Flash Kernel. Multirom manager also reflects that is built in.

@The Flash
running great with PN 7.0 here.
although kernel manager doesn't show all hotplugs...kernel-aduiter shows only 2 i think and elementalX-manager doesn't show 1.....sorry forgot specifics coz i removed both and have no managers install now.
anyway, quick question:
u have better knowledge in this area than I do...whats the diff between interactive from this kernel and interactive from lean kernel...I have heard great things abt leankernel but never got the chance to run it coz by the time i bought nexus 5 he already moved to nexus 6...by the time i bought nexus 6 he already moved to nexus 6P...lol

LeanKernel uses InteractiveX - Imoseyon's own version of Interactive with a screen off max freq. Interactive is a stock governor. This thread is GREAT for learning about all the awesome governors in this and other kernels - I personally use Darkness. http://forum.xda-developers.com/general/general/ref-to-date-guide-cpu-governors-o-t3048957 Hope this helps bud!

@The Flash
Your kernel runs really great with Tesla! It seems like a rocking solid beast!

@The Flash Looks great, will it improve battery? And what kernel settings do you recommend for a 4 hrs sot?

It should, I've added a lot of optimization packages. The default settings should be getting you more than 4 hours of SOT but you may try tweaking the governor and hotplug settings.

Running & sleeping well on the 10/10 build of Uberstock. Thanks for sharing your work!
