[Q] CM11 bootloop after enabling kernel module support? Help!

Hi guys,
I've been compiling CM 10.2 with loadable module support for some time already. The only change I had to make was to modify appropriate configuration parameter in cyanogen_mako_defconfig file (change to CONFIG_MODULES=y). Since CM11, kernel compiled with this change gives me bootloops. If I revert the change back, compiled kernel functions properly.
Any idea what would be (additionally) needed to build CM 11 kernel with loadable modules support?
Thanks!

Did you resolve this? I hit on the same problem. Once the modules are enabled it enters into boot-loop.

Unfortunately, no.
Had to give up cause I didn't have the time to try anymore.
I took the easier route and currently I'm on kernel from crDroid simple.

Thanks. I went the same way. Extracted the kernel from crDroid rom and flashed it.
But anyway interesting why cm team broke this option in the kernel. Will they fix it in future?...

I really don't know. Since CM team decided for their rom not to have module support anymore, seems that talking about that topic is kind of a taboo.
Anyway, since module support is not something CM is interested in at all, I doubt anything will change. At least not intentionally.
Having in mind that there are many kernels based on CM which have module support enabled, it is not impossible. It just requires some more understanding and work how to do it. I asked this on many different forums and got 0 answers.

LG uploaded V500 kitkat kernel source today!

https://www.lg.com/global/support/opensource/opensourceList?types=ALL&search=lgv500
Is where you can get it (start your downloading now...)
the strange thing is they appear to have two uploads for kitkat...

Yay! What does it mean for the simple user? Better roms?

All I really want is gamma correction and maybe overclocking and U/V.

This means that anyone interested in building a replacement kernel for the LG stock 4.4.2 release has a blueprint to start from. I know of two kernels that have been released for 4.2.2 stock, this release means that we may see updates of these projects to 4.4.2.
I may try and restart my own efforts in this area as well depending upon time and what kind of problems I find in the 4.4.2 US release.

The first and most obvious is the gamma set at 2.05 roughly. If you set it to 2.2 - 2.3, that would already be a big plus.

The source uploaded by LG didn't include the kernel source so I contacted their open source division and they've now uploaded a proper kernel source. I'm travelling for work now, but will take a look at it when I get back home next week and get something compiled.

Good to hear that someone else contacted them as well. I have been impressed with their open source group responding as quickly as they did. They definitely respond better than several other companies when facing these requests!

:good::good: I would pay anybody to incorporate or activate the OTG+Charging in this Kernel. :good::good: :fingers-crossed:

When if get the chance can you compare the 18a kernel to the 20b one? I like the settings the 18a kernel, the lower brightness levels are setup in a way that makes it great for night time. I have the 18a kernel running on the 20b build but after the screen is locked it and turned back on it changes to levels of the 20b kernel, but retains the gamma level. I could attach a flashable zip with the 18a kernel if you need it.

Hi, I am quite a newbie. Just wondering what is the use of the kernels? Can we just flash it on custom roms like the kitkats ones done by _infected. AOKP or the Cynogenmod for the GPAD? The AOKP and the Cynogen are smooth but few features like Autorotate doesn't work and there is no gamma correction i think

I compiled a kernel using the source provided by LG, but for some reason, it doesn't boot.
I keep getting this error:
Code:
Secure booting error
Cause: boot certification verify
I noticed that the resulting "boot.emmc.win" is a lot smaller than the original boot.emmc.win (~10 MB compared to 24MB)
Another interesting thing is that if I uncompress the original 24 MB boot.emmc.win using the command "unmkbootimg -i boot.emmc.win", I get two files: kernel (7.5 MB) and ramdisk.cpio.gz (2.6 MB). If I rebuild the boot.emmc.win using these exact two files, I get an 11MB boot.emmc.win, but this one DOES boot.
It probably has something to do with the locked bootloader and the loki exploit.
Can anyone help me get to the bottom of this? I really want to solve the gamma issue.

Well, as I suspected, it was because of the locked bootloader, but using the loki_tool, I was able to bypass the bootloader check.
So I now have a working, self-compiled 4.4.2 kernel (using the eabi-4.7) , based on LG's kernel source.
Unfortunatelly, gamma is still the same (about 2 - 2.1). Need to figure out how to modify it.
If someone can and wants to help, I'd greatly appreciate it.

Can you look at the 18 Rom kernel and see what has changed?

Panel is very close to correct gamma when using default linear qlut, instead of MSM_MIPI_LGIT_VIDEO_WUXGA_PT_PANEL qlut.

I would definitely take a look at the 50018A kernel if someone can provide the source. I wasn't able to find it.

The kernel is what drives the Rom. Without the kernel sources improvements to a device are hard to make. It's AOSP ( Android Open Source Project) not AOKP.

Hello ruxandy,
Can you explain in few words how did you manage to push the kernel to your v500?
Here is my story:
I downloaded the V500 Lollipop kernel because I wanted to compile .ko loadable modules and drivers to support RTL2832U DVB USB dongle. I successfully compiled those modules, rooted the tabled and tried to insmod them. But it failed because the modules did not find some kernel APIs.
Then I decided to build the kernel with built-in those drivers and I did it successfully, the problem now is what to do with zImage. I read there are two roads the one building own KDZ file seems very complicated and not sure if really possible. The other seems to be to extract the boot.emmc.win file using TWRP. So I downgraded the V500 bootloader from LT to KK and installed TWRT using this http://forum.xda-developers.com/lg-g-pad-83/help/v500-how-to-install-twrp-stock-lp-t3165846 but after reboot got the secure boot error you did.
So again - how to use self built zImage and is this possible for KitKat only, since installing TWRP with Lollipop does not seem possible so far?

Lollipop Kernel

Hi people,
With the recent announcement of @pedestre (creator of apolo kernel) that the development of apolo kernel comes to an end and Gustavo kernel does not be updated since a long time, we have no costum kernel for the many 5.1.1 roms that are coming to our phones....
Many people uses bln, cpu and gpu voltages control etc.
I want to ask someone with skils who can compile latest cm kernel, witch i think that will be compatible with all newest 5.1.1 roms, with basiclly feautures like bln and others... and if its possible, keep it update with lates cm realises....
Thanks, i hope some dev can help us

Yes, we need kernel developers

Always been considering to build a kernel, especially porting dorimanx to lollipop. Having trouble on ubuntu with dorimanx's instructions, so I will try bbqlinux instead and see how it goes.

I can develop if @pedestre can give me the permissions to let me continue Apolo. Although, I'll do that and all the other ROMs' building stuff after 6th of June.

I'm sure he would give you persmission to do that.

Right now I'm cloning my repo of dorimanx kernel. Have made a few changes like chhapil (except no uber tc yet). I'll see if I can release something next week (however will be very busy with exams). I'm still very new at building kernels so expect a few quirks with the kernel.

Should be alright since android kernel is open source.

Developers please come forward we beg you!

@warrior1208 Instead of continuing a Kernel, why not make and develop one yourself and name the kernel yourself as well? It would be nice if there's a new kernel name in our device. Just suggesting here...

Let's see. I'll try. But first, I have to update all the three ROMs and then a custom kernel. Although, as I stated, I'll be able to do that after 6th of June.

I vote for gustavo's kernel since last version of it was just everything i needed. Miss it's colour control very much

I would love to see a TWRP kernel, as I use the file manager to delete unwanted system files on rom updates.
I do think it has a more friendly UI too.

We need 2 type of kernel. One like gustavo_s' and other is like apolo.
One for full control
And other is daily usage and more stable

Or maybe one based on apolo with CPU and GPU OC

I'm pretty sure there not much work needed to get Gustavo's kernel working on newer lollipop builds. Right now, I've made changes to io schedulers, TCP algorithm, supersu. Still have no clue how to get build started, at least there's progress. Change of mind. Will be busy with exams.

Actually no, everything can be done through terminal. That is, indeex, how apolo configurator/stweaks or any other such app works. Just executing commands.

It finally boots with working WiFi! That was the biggest breakthrough the past day. So far, the expanded feature set isn't too large, but it will only grow now that the basic functionality is confirmed. There isn't an immediate increase in performance or features compared to Stock Kernel so far as I can tell, but you can adjust settings with EX Kernel Manager. Kernel Audiutor is more limited.

Be careful using this Kernel (Thunderstorm kernel from Revanth).
It has some bugs like battery drains with no solutions.
In the other hand, the developer manages a telegram group where he and its admins insult users. Very bad support.
I think it's so dangerous to install a kernel come from annoying people and a bad developer wjo doesn't know all the bugs his kernel brings.
Try Code-x kernel for ROSY.
