Not necessarily. A common method would be:

Chris, I would like to ask where should I put rtems-boot hd image needed to
run pc386 on qemu. Should I create some directory under rtems-tools and put
image into it?

Fix context switch on SMP for ARM, PowerPC and SPARC.
Atomically test and set the is executing indicator of the heir context
to ensure that at most one processor uses the heir context. Break the
busy wait loop also due to heir updates.

I guess I should clarify further, set_vector usually just calls some
function that installs a "template" in the handler, which consists of
basically calling a function. You can see some examples in the
cpukit/score or the SPARC is at libbsp/sparc/shared/irq/

For a "simple vectored architecture", the usual approach in RTEMS is
to implement some "set_vector()" function that will install a function
pointer in the IRQ table. This function pointer will either be called
in "rtems" mode via trampoline code (ISR_Handler) that sets up a safe
C environment, or w
