Our lab has recently acquired a 48-node IBM SP configuration based on
4-way "Winterhawk-II" Power3-2 wide nodes with 8 GB memory. I see on the
Linuxppc site (boxes) that Linux is known to work on 9076-SP nodes
(ours). How difficult is the port? IBM does not support Linux on the
9076 but does on the newer Power4 pSeries units.

I guess that, since these boxes are basically just rack-mounted chrp,
rs6k's, getting linux to run is easy. Getting the os on there may
require some creativity, since sp nodes don't come with a removable
media, so you'll have to net-boot&install, but iirc, these boxes
basically do tftp, but I guess you still need a working
control-workstation to be able to set the netboot. (I have never had
the oppertunity to play with an sp-node at this level)
as long as you don't need the sp switch (if you have one) all hardware
is supported, ge, fe and even the scsi are quite common hardware, just
with an IBM sticker&price-tag ;-)
(I wish I had a few spare wh-II's to play with :)

Hi,

We've booted linux on winterhawks in the past, there was one weird
problem where we allocated memory for RTAS too high but that should be
fixed.
As pointed out we have no support for the switch unfortunately.
One of our build machines here is a nighthawk (16 way 9076) and it works
nicely in case anyone has a cluster of these lying around :)

unfortunately, IBM wanted ours back when it was traded in for 6 32way
p690's.... we had 8 16cpu nodes ;-)

Hi, all,
when debugging kernel or driver, we need to read/write registers of CPU and devices. I wanna use /dev/mem to do, is it possible? if need to do others things? is it better to write a driver for read/write CPU/device's registers by myself?
Do you have any good advice?
Thanks in advance!
John
