Documenting devices with mainline Linux support - Help needed
 

Some of you have already seen my recent rants [1] [2] [3] on how the Xperia X and the Gemini PDA use Linux kernels that originate from AOSP. It's a source of frustration for me that I still can't pick up a mobile phone and install whatever Linux distro I like, as I can with a PC. Whilst I think libhybris is a wonderful achievement, I can't help but think a solution that is tailored towards Android hardware adaptation does not help us in the long term as it embraces Android blobs and encourages the use of old Linux kernels from AOSP. I want to evolve my DebiaN900 project into something bigger but it's just not possible to build a secure OS for mobile devices by using EOL/unsupported Linux kernels from AOSP on Android devices with planned obsolescence.

Let's forget about which devices are supported by CyanogenMod/LineageOS for a moment and think about which devices are actually supported by Linux. I decided to do a bit of investigation to find out what mobile devices have at least some mainline kernel support. I've started by looking at the device trees included in mainline Linux. I've made a list, which may not be complete but at least it's a start.

Only a few of these devices have comprehensive public documentation on what hardware works and what doesn't. I'd like to start documenting the other devices.

I want to hear from anyone who has tried running a mainline kernel on any of these devices where documentation it lacking, even if it's with Android with mainline Linux. I plan to create a wiki page with a table similar to what Mer have done for their libhybris adaptations to provide a simple comparison of what is supported on each device. I'm more interested in documenting mobile phones over tablets and other devices but if anyone fancies helping with those, I won't stop them. :P I don't know if I've found every single mobile device with a device tree in mainline. If you find one I've missed, please let me know.

It should also be noted that mainline Linux also includes support for many SoCs for other popular mobile phones (Samsung Exynos, etc). These have device trees for development boards but are missing device trees for phones. It may not require much effort to get some of these phones working.

Re: Documenting devices with mainline Linux support - Help needed
 

Does it make sense to include Intel-based tablets? Generally, if they came with Windows 8 or 10 (there can be locked bootloader in case of Android), they have normal UEFI firmware and can boot mainline desktop kernel, but the level of hardware support and quirks needed to get it working will vary. The situation is getting better though, for example GPD Win is mostly supported now.

Re: Documenting devices with mainline Linux support - Help needed
 

Yes, it does make sense. There are currently no x86 devices on my list as it was based on device trees found in the kernel and x86 does not use device trees. If anyone has tested a mainline kernel on x86 devices and can help document them, I'll add them to the list.

That's good news about the GPDWin. Hans de Goede has done a lot work on mainlining devices. His name can be found in the header of many of the device trees above.

Re: Documenting devices with mainline Linux support - Help needed
 

Quite an impressive list you have compiled there. I have two old, el-cheapo Wondermedia tablets that can both run Debian and I was wondering (pun intended) if anybody still remembers them but you have impressed me :)

I reached the character limit in the original post so I'm moving "Other" devices to this new post to make room for new entries until I get around to moving it all to a wiki page...

Re: Documenting devices with mainline Linux support - Help needed
 

Some information about the Kobo Clara HD:
Mainline misses several drivers, I am working on upstreaming things. The battery driver is accepted for v5.10.
For more information:
https://misc.andi.de1.cc/kobo
Patched mainline kernels:
https://github.com/akemnade/linux
branches kobo/merged-5.X (currently v5.8). There is a kobo_defconfig.

The Tolino Shine 3 is the same board as the Kobo Clara HD, just the SoC is different. Unfortunately, the EPDC is different enough so that it causes trouble with above-mentioned kernel. Graphics is not working well.
