Who cares about PReP?

Who cares about PReP?

[Paul Mackerras]

I started looking at moving the PReP code over to arch/powerpc.  I am
struck by how many ifdefs there are in there to set things up for
particular individual PReP implementations.  We can do better than
that, I'm sure, but the issue becomes one of testing.  The only PReP I
have here is an RS/6000 43p-140.

Who else has a PReP system and would be willing to do some testing and
debugging?  If so, what sort of PReP is it?

Paul.

I have that also on my list. I have an MTX+, a 43p 130, 43p 140 and a Powerstack.

Hi,

I have motorolla vme boards that seems to me are PreP.
The boards are mvme5100 and mvme5500.

I've still got a Motorola Powerstack (Series E) around.

QEMU PPC implements a PReP system too.

Probably a good place to test without needing a real system.

However it's the kind of thing you'd want to throw a CHRP
ROM onto in the end, and forget PReP for emulation (after
all, nobody makes 'em anymore).

We are using 20+ MVME boards here so I am interested, 
MVME2400/2600/2700 to be precise. 

Right now I can test patches and not much more, I'm really 
short of time and fighting other issues. Among them my PB 
G4 from last December just completely failed (and Apple 
told me to bring it to a shop in this city that is closed 
for holidays until ... September 4th).


	Regards,

If you (and anyone else who is interested) could send me the contents
of /proc/residual, /proc/iomem, /proc/ioports and /proc/interrupts
from your systems (one of each different type) that could be helpful.

Thanks,
Paul.

And /proc/cpuinfo would be interesting too.

I've got a MVME2604 that I've been itching to fire up with Linux.

I have a 7248 43p-133 available for testing.
