clocks on mips

I've been looking at arc.

It appears that all arc systems have a MIPS 3 clock and can handle clock
interrupts on CP0 counter.  I think this is probably also true of
hpcmips.  For pmax and company, it is probably true for _some_ models.

I'd like to recommend the following:

1) convert those models that can do it to common mips3 clock code in
mips/mips/mips3_clock.c, modulo the following comments

2) this means in the short term, loss of statclock.  i propose that the
statclock be handled by the external clocks (whatever are present) when
they exist.  i.e. I'm suggesting that the statclock timer be the
"optional" clock, and that the mips3_cp0_clock always be used. 
statclock/stathz, etc. should be set up by the MD code.

3) this probably means cleaning up mips3_clock.c somewhat -- the
statclock needs to move out of it, and the delay() needs to rename to
mips3_delay.

4) for systems that can just use mips3_delay as is, I would use a weak
symbol alias so that at link time delay() is resolved to mips3_delay.

5) I'd like to rename cpu_initclocks() to mips3_initclocks() and weak
alias it as well.

6) I'd like to move the resulting mips3_initclocks() and
mips3_clockintr() into a new file, mips3_hardclock.c or
mips3_clockintr.c, so that ports which for some reason can't use these
(ews4800mips?) don't have to carry the baggage, but can still use the
rest of the code in mips3_clock.c

Thoughts?

ISA bus-master DMA on arc

Has anyone tried any ISA bus-master DMA devices on arc machines?

AHA-1542 on my Express5800/240 EISA (NEC-J96A) hangs during
probing attached drives, so I wonder if I have to fix ISA DMA stuff
before I work on EISA stuff to support mlx(4) on EISA on my J96A.
(Note PIO devices like ep(4) works fine on it)

64-bit paddr_t and mmap()?

I'm trying to mmap a framebuffer device under evbmips, using a 64-bit
paddr_t.   (Alchemy PCI space is located in the upper portion of the
36-bit MIPS physical address space.)

Anyway, the mmap works fine.  I'm able to draw a picture on screen.

But when the application exits (and hence does an implicit munmap()), I
get a panic in pmap_remove_pv, called from pmap_remove, where it looks
like a NULL "pg" pointer is being passed.

I'm curious if anyone else has used 64-bit paddr_t's and mmap(), e.g. on
ARC.  I'm wondering if maybe I'm trying to do something new, or if there
is some known fault, or if it is known to work on other platforms.  Any
info that might help me restrict where I am looking would be useful to
me.

Hello!

I have a NEC RiscServer 4200 and a Deskstation Tyne Motherboard that  
I am willing to give to a developer who is interested.
