Hello,
We are looking at an application where we will need an FIQ to be able to
interrupt an IRQ and I have been looking at support for this. It seems
like there is no nested interrupt support for ARM and that FIQ support
is very limited, in that it effectively turns it into an IRQ to be
handled after current IRQ. Am I missing something here?
Has anyone done any work to support the FIQ properly on ARM? Anyone able
to comment on why it was done this way in the first place?
Thanks
Will
