> Linux-compatible ABI

Does it mean it can re-use the drivers written for hardware to run with linux ?

No. There is no stable ABI nor API for in-kernel device drivers.

No. The drivers in Linux are kernel modules, most often in-tree - meaning that the source for the drivers is built along the rest of the kernel source code. Most hardware drivers depend on various common kernel structures that change often - when they do, the source for drivers is fixed practically in the same git branch. There is no driver ABI to speak of.

Do other mainstream kernels have a stable driver API?

I guess the NT kernel needs to. Does Darwin?
