May I ask why I can not download kernel 5.15 with the newest brunch unstable?

Thanks

Standard Kernel 5.15 was not working properly with android apps on recent ChromeOS releases due to a missing kernel feature but you can still use the "chromebook-5.15" kernel.

What is a difference between normal kernel 5.15 and chromebook-5.15?

I will test it anyway Thanks

The chomebook-5.15 kernel uses chromiumos kernel source whereas standard 5.15 kernel used mainline.

The chomebook-5.15 kernel uses chromiumos kernel source whereas standard 5.15 kernel used mainline.

That is not explain anything ;)

Are bigger differences like chromiumos 5.15 kernel has cut off drivers or something?

Thanks anyway.

It uses ChromeOS-Flex config. If you need a specific config and that it is missing you can post it here.

My device has a very specific es8336 driver ... Any official driver es8336 is not working.

I have a source of that driver only for kernel 5.12 but also working ok with 5.15 but is not compatible with higher kernels ( too many changes )

I tried integrate the driver with chromium 5.15 and is giving errors during building ... different members of structs or one function has too many arguments.

With vanilla 5.15 is can build that but with chromium 5.15 not ... 🫥

If you want I can provide you that driver ( very old driver for es8336 is called esxx8336)

What "missing kernel feature" ? Maybe I will backport it from chromium kernel 5.15 to vanilla kernel 5.15?

What do you say ?

[mirek190]

I just want inform you I fully ported driver to kernel 6.1 ;)
