[KERNEL][WIP][BOOTS] CAF Linux 3.10.40 kernel

This is a booting CAF 3.10 kernel for none other than our shiny OnePlus One. Personally, I'm satisfied with my phone as it is with a 3.4 kernel (and 3.10 is a lot of work without proper firmware), so I've given up on developing this 3.10 kernel. This thread is just a free-for-all for anyone who wants to have a crack at developing 3.10.
I threw this kernel together pretty sloppily 2 months ago, so I apologize for the lack of full git history from CAF and some messy code from me. The kernel is based off of the LA.BF.2.1_rb1.xx branch from CAF. The kernel should boot as-is on the official CM nightlies, and it is confirmed to boot on my CM12.1 builds. All it requires is updated WCNSS configuration binaries to boot (flashable zip available in the downloads tab of the thread). The kernel currently only supports JDI command-mode panels, and I compiled the kernel with Google's GCC 4.8 toolchain.
Source code: https://github.com/sultanxda/android_kernel_oneplus_bacon-3.10
What works:
It boots (woo)
Display
Touchscreen
Modem (no mobile data though)
WiFi
Charger (not from wall outlets though)
Battery percentage/health reporting
Volume keys
Sensors
USB
Assume everything else doesn't work. Here's a fun screenie: http://imgur.com/H1UERfr
Good luck with haxing 3.10!

Tons!
One I would love to mess with is Heterogeneous Multi-Processing. Also some of the other upstream scheduler commits. For one, they are what make the N6 a true quad core in that it doesn't use any hotplugging, just CPU C states while maintaining pretty decent battery life. It changes how threading works and how workloads are transferred to other cores. At least this is the main thing I would love to see and mess with. Almost makes me want to get an N6. I love my OPO though.

man, that would be cool but it would be a massive undertaking then you would need a road map for other rom Devs to use to even use the work you have done let alone to even be accepted officially from major Roms out there like CM. This is something I have thought about alot but the work needed to put in doesn't match anything near what I would get out of it. This doesn't mean money necessarily but time, time away from family, etc.
This is still something I will take a look at. I wouldn't mind any input from @DerRomtester at all.

[INDEX] OnePlus One Resources Compilation Roll-Up

First I was excited then I read that this is no longer in development and I'm sad now
P.S. I'd love to see a small group of kernel devs gather around and work on this, surely at first it would be buggy, having even less performance than any kernel for our 1+1 but in the end we'll have a sweet little kernel

Pretty sure that most devs would use this as a base if it had the proper driver support as it would provide quite the bump for security

Facts. We need way more collabs man. Unity gets a lot done. I personally know nothing about developing, but I'm a great tester. I'm willing to brick my phone.. Test, bootloop and brick it again lol. Everyone can play a part in the grand scheme of things.

@Sultanxda can you share your kernel with me?
I compiled it but i don't get it booting. You have made some ramdisk changes ? You added an dtb file ?

No ramdisk changes, no missing dtbs. Just ran a mrproper and compiled it exactly as it is on my GitHub, and it boots. Compiled with GCC 4.8 from Google using almost the exact same script I use to compile my 3.4 kernel, with the only change being that the dtb path for the dtbtool is arch/arm/boot/dts/, not arch/arm/boot/ (though you probably already figured that out).

If companies released the drivers we would have 3.10.x, 3.18.x and even 4.2.x kernels(someone would try to do it even if it turned out a failure)
Released drivers also would have better optimised roms and would make a 5 year old device to live forever (new android e.g. android 7? no problem)

I'm the worst kind of programmer, I mean I do own a degree but the programming language was my weakest link, so I can't help and kernel is one of the hardest parts it needs big ..knowledge to do it :silly:
Now lets not go off topic and wish for someone to work on 3.10.x I mean even if it's buggy and a bit unstable it will bring some new stuff and when it gets stable well then the fun will start

I wasn't exactly interested in 3.10 until i read yours comment. If this kernel can also make opo work like N6 i.e. running always on quad core mode and still maintain good battery lyf, man i would pray that either opo or cm releases 3.10 kernel.

This will never happen. From a business perspective, it costs too much for little benefit, and only introduces the potential for more bugs.
However, here is a hint: Bacon's TrustZone firmware does not check metadata when loading firmware images, so you can technically load firmware from any device (ex: you can use Venus firmware from a totally different device).
If you know what you're doing and you have 3 months of your life to burn on this, then it should be possible to get everything working with the LA.BF.2.1_rb1.xx kernel branch.

Robin Custom Kernels?

I only see an AOSP only Kernel but no others. Is it lack of Dev interest and a less people owning this excellent phone?

Build it yourself man

Franco tried to develop a kernel, but he said there were too many issues when trying. Nextbit sent him a Robin even. Maybe when nougat is released? It's unfortunate cause battery is pretty bad

I will get right on it after my paper in to theoretical physics is finished.

Building custom kernel for robin at the moment it's totally waste of time. I'm waiting the 7.0 Source for make custom kernel

Lineage for this device?

As the title states. Now that we have root and an unlocked bootloader do you think lineage is will make its way to this device?

Not a fan of lineage code.
We need a aosp rom like Purefusion.

We need Kernel source from Motorola first. They are dragging their feet like always. Without kernel source, we can't get a 100% working TWRP for custom roms to flash

Agreed. We need them to drop source code like they said they would.

Looks like I may be getting this phone instead of the Note 8. Come on Motorola......release that source code.

They aren't going to acknowledge you here. Follow this link and sign up to let them know how you feel.

Kernel source was given by Motorola. There is my git with the edits for a regular machine running GCC 4.9 to build a kernel that boots and works.

How much less is less?
If you build it they will come.... ("Field of Dreams" movie line) Seriously, though, I do wonder if giving up stability and features is worth it for minimal gains in performance/benchmarks? Motorola's take on Android is already bare-bones compared to Samsung! With Lineage, it's slightly easier to theme, true, but Substratum suffices for many individuals on stock. I haven't tried Substratum yet, because I don't like dark themes. Don't get me wrong, I want Lineage to succeed! The more open-source options the better! But, is it worth it for the principle, or modest increase in speed (maybe)? Bugless and not losing any features, I would run Lineage; so, we'll see, because it will come in due time.

Totally correct. Our device is so close to stock it's ridiculous. We pretty much have a pixel phone with slower updates and mods. Which I'll take over the boringness of a pixel. Yes substratum would be pretty cool but I know things are coming we have a kernel being updated to the latest kernel version available. We're testing twrp right now and have it 95% working and now we have twrp and magisk and an updated kernel all going at once things are coming along slowly but I feel they will pick up soon

Yes, they were released. Kernel builds fine. For AOSP stuff we need vendor files. We are piecing things together. All builds have failed so we haven't even had a chance to see if it boots.
Why hasn't a kernel been fully released? (Besides the upstreamed one in the custom ROM section) because of encryption not working right in TWRP, you'd lose root when flashing as TWRP can't put the ramdisk back correctly hence no root.

Somebody should start Lineage. I would do it if I had enough experience but I don't yet. Huge tasks like LTE not working, etc., can arise depending upon the particular phone....
The attached screenshot illustrates the dynamics quite well. I was initially mildly surprised by the Lineage developer's response to someone, "When you start paying me." But, for some developers who devote lots of their time to Lineage, I suppose the questions can become tiresome. Every developer is different, of course, and it is a global scale endeavor.

Good, stable ROM

I'm looking for a nice stable ROM compatible with jolla-kernel or having blue_active as a CPU governor. I'm currently using Paranoid Android, I used to use Lineage OS but the bugs that occurred were very big deals

Pure Nexus. That's the one I use. Oreo is still under development, but the 7.1.2 PN worked great with Jolla.

Hey, I used many roms for the N5X and the only one that is still smooth and with good battery life is Pure Nexus as my colleague mentions above ^.
Anyways, tomorrow is @argraur releasing new version of his PixelROM which I hope will be great

I've also tested many ROMs before I settled on PN. I used RR, DU, PR, and more than a few kernels. PN + ElementalX is my favorite (I know I need to update my sig, oh well).

I got really in love with RR, it has so many features and its smooth also, althought DU is/are quite similar with poor performance. PN + ElementalX worked for me the best, however i'll try out the new GooglePixel ROM based on Pixel 2 features :victory: :victory:

Pure Nexus does look promising, but my problem is I have the bootloader for the August update. I guess I could have specified, but I would also like the ROM to be on the small side too so I have a lot of storage left. I'm a big tech person, so I'd also like to be able to root, and I'm worried about a lot of features. Stock Nougat had enough features for me

You can flash new bootloader but it's not necessary, it will work well even with older one . The PN rom is about 4gb as usual after installation and you can also root it afterwards... I don't understand your concerns probably

Kernel Auditor is one of the more popular ones, although I haven't used it in a long time since I switched to EXKM. Especially if you're using the Elementalx kernel, it's fantastic. Even if you're not, it still does a great job.
It's only one of the 3 apps I've ever bought, and I use it on all my phones/devices. I figured a $400 phone can justify a $4 app, amiright?

Just curious...what are you looking for specifically that is special/unique that doesn't exist in actual Stock Roms provided monthly by Google? Can't get more stock than actual Stock.

Usually that would be a developer that's based solely on stock that would keep the graphics drivers updated with speed tweaks Etc. But it looks like those days are gone.

Back in the OG Droid, Droid Razr Maxx days I used to fully invest time and energy to run custom Roms as I also wanted to take advantage of overclocking CPU to maximize the performance of my device (which typically were underclocked by the OEMs). But, I haven't had to go that route in some time. I find the Stock experience provided by Google to be pretty good from a performance standpoint and the Pixel XL experience as far as monthly updates has also been exceptional. If you still have your heart set on having control of CPU clock speed settings and additional custom tweaks not available in the Stock experience - you should look at some of the custom kernels (or Roms) available. I believe there are custom kernels that will run with the true Stock Rom that will provide you greater flexibility.
Good luck.

Funny, I am currently running an custom Kernel on top of stock Android. You're absolutely right about Google's stock builds and performance. You gave great information because that's in fact what I am doing to date. Custom ROMs today are becoming too bloated with issues and issues. Again, thanks, and have a great day.

ElementalX Kernel.
Well, I picked this one mostly because he's an OG of the kernel scene. I personally don't do anything extra as far as extra features. But I just keep the script on his preferred settings, and I click install. I'm not into the overclocking, but I'm not too shy to underclock. I usually install custom kernels because of security updates and performance updates that they add due to Google's monthly developer updates.
You're welcome, no worries.
