Mark bsp_reset() as no-return. Use default BSP fatal handler in lm32 and m68k BSPs. Remove empty bsp_reset() implementation. Update #5067.
MVME147
MVME147 port for TNI - Telecom Bretagne by Dominique LE CAMPION (Dominique.LECAMPION@enst-bretagne.fr) May 1996
This bsp is essentially based on the mvme136 bsp.
Summary
-
include
- bsp.h Peripheral Channel Controller memory mapping Z8530 memory mapping
-
startup
- bspstart.c main () setup for VME roundrobin mode setup for the PCC interrupt vector base
- bspclean.c bsp_cleanup () disable timer 1 & 2 interruptions
- linkcmds set the RAM start (0x5000) and size (4Meg - 0x5000)
- setvec.c unchanged
- sbrk.c unchanged
-
console
- console.c taken from the dmv152 bsp (Zilog Z8530) with no modification
-
clock
- ckinit.c entirely rewritten for the PCC tick timer 2
-
timer
- timerisr.s and timer.c entirely rewritten for the PCC tick timer 1 now gives results un 6.25 us units (mininum timer delay, suprising big grain)
-
times
- updated results for the mvme147 (beware of the 6.25 us grain)
-
Makefiles
- compilation of shmsupp simply removed
To be done:
-
add VMEchip memory mapping to include/bsp.h
-
update the overheads in coverhead.h
-
add support for serila ports 2,3 and 4.
Other notes:
-
There is no MP support (no more shmsupp) because I have no experience of the VME bus. The mvme136 shared memory support does not seem applicable on the VMEchip of the mvme147, so I don't know where to start. Suggestions are welcome.
-
All the timing tests and sp tests have been run.
Future work
-
Add gdb serial remote support.
-
Shared memory support (I don't really need it, but I can do it if it's simple).
-
Message passing on VME bus, with Ada 95 annex E (distributed systems) in mind.
