Android's "Treble" interface

The Android Developers Blog carries anannouncement for an upcoming feature called "Treble", which looks likea separate, guaranteed stable interface for device drivers. "Thecore concept is to separate the vendor implementation - thedevice-specific, lower-level software written in large part by the siliconmanufacturers - from the Android OS Framework. This is achieved by theintroduction of a new vendor interface between the Android OS framework andthe vendor implementation." Details are scarce, and there is noinformation on how this might fit into the part of the "Android OSframework" that many of us think of as "the Linux kernel".
