Linux Linus Torvalds included patches into the mainline tree which implement a stable userspace driver API into the Linux kernel. The stable driver API was already announced a year ago by Greg Kroah-Hartman. Now the last patches were uploaded and the API was included in Linus' tree. The idea of the API is to make life easier for driver developers: "This interface allows the ability to write the majority of a driver in userspace with only a very small shell of a driver in the kernel itself. It uses a char device and sysfs to interact with a userspace process to process interrupts and control memory accesses."

Very interesting. Definitely something to keep an eye on.

The last few years Linux (the kernel) has seemed bloated, buggy and crufty to me, full of fun experiments in instability causing me much self-induced grief as I've played with it on various systems.

If this API becomes widely adopted by driver developers and proves to be as stable as I'd imagine it to be, I could almost see Linux being a system I'd run full time.

Not so much from the point of view of possibly getting binary only user-space drivers, but more due to getting the majority of free driver code out of the kernel, (hopefully) making the system more solid.
