going mainline

[khumarahn]

I still did not have time to try the mainline kernel... but I really miss it. For example, it should have a good implementation of f2fs.....

How is the mainlining going? Am I correct that the mainline-kernel debian image is usable except for the sound?

How is the mainlining going?

The mainlineing itself: Quite good. All of our work (or something equivalent by others) has been accepted by now except for a pwm DT node. So you will need a custom DT even with 4.17, to get a working backlight.

Also support of mainline u-boot is still missing, but that's other peoples work and their decision when to submit the patches ...

There is now a guide on the debian wiki with some extra details:

Am I correct that the mainline-kernel debian image is usable except for the sound?

usable: absolutely. I'm booting more often into the debien image then into preinstalled ubuntu these days.

missing: sound, HDMI (looks like this might come around soon), battery driver (might be easy, nobody looked into that yet), cpu frequency scaling.

Also currently there is no way to wake up the system from suspend - but nobody tried hard to get it working either, so might be something trivial.

HTH,

There are some patch around for battery driver:

But they are not yet in mainline kernel.
