Hello, This page https://www.freebsd.org/doc/en_US.ISO8859-1/books/arch-handbook/smp-design.= html says that "These interrupt handlers are currently misnamed =E2=80=9Cfast=E2=80=9D int= errupt handlers since the INTR_FAST flag used in earlier versions of the kernel is used to mark these handlers. The only interrupts which currently use these types of interrupt handlers are clock interrupts and serial I/O device interrupts." I want to use INTR_FAST for my spi controller, but i find that it is not defined on freebsd stable11. Is INTR_EXCL related in any way to INTR_FAST? if not, how do I setup a fast interrupt handler? thanks -kamal
