Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG What about shared interrupts? How are they going to be treated? With the spl leaving the arena it somehow looks feasible to run one interrupt source on two different threads if there are two pieces of hardware attached to the same interrupt line. From what I understood from dfr, when switching away from an interrupt handler it is converted into a full thread. When the second piece of hardware fires an interrupt it could then run at the same time.
