Can anyone explain how this works in modern Android? Do the drivers for this specific hardware live in Treble? Can they "just" drop a new kernel in a point release, like linux 6.5 vanilla? Or linux 8.5 vanilla in the year 2030? I am not an Android user, but do have some interest in following what is happening. I do have interest in mobile Linux, currently I am using Sailfish OS with libhybris drivers and an old kernel.
