Interrupt in RTEMS

I guess you might look at how a particular CPU handles interrupts. The
CPU Supplemental manual provides some details:
http://rtems.org/onlinedocs/doc-current/share/rtems/html/cpu_supplement/cpu_supplement.html

RTEMS supports up to 256 interrupt priority levels, but CPUs might not
support so many.

Number of interrupts depends on how many interrupt sources the CPU supports.
