Hi all.

A general question about Linux.

Is Linux a fully preemptive kernel?

Thanks

Not natively, for efficiency reasons.
But you can get several fully preemptive patches for the kernel, such as

Linux kernel 2.6.X is described as fully preemptive. The patches mentioned above were merged into 2.5.4.

Oops !
Right Mark ! I forgot to precise that I was talking about good old 2.4, the one on currents distribs !
Tested 2.6 too, really impressed...
