[rescue] dmesg (OpenBSD) from Tsparc 170

[Patrick Giagnocavo 717-201-3366]

Attached is the dmesg from a minty new OpenBSD 3.0 install on the
TurboSparc 170.

I have a few questions about the devices:

esp0 at dma0 offset 0x8800000 pri 4: ESP200, 40MHz, SCSI ID 7

Above is the SCSI controller, right?  What are the specs - I mean it's
not really a 40MHz SCSI bus, is it?

And what is a "slavioconfig"?

On boot, the machine reports 1024KB of L2 cache.  The dmesg doesn't
show this, I think. Unless there is something in the iommu line.

I think I understand the other stuff, or at least enough of it :-) .

Trivia note : SBUS clock speed was decreased on these systems as the
speed of the CPU increased.  On a Sparc 70-MHz, the clock speed for
SBUS is either 25 or 23.375 MHz (IIRC).

Cordially
