mppb — Prometheus
PCI bridge driver
mppb* at zbus0
pci* at mppb?
The mppb driver provides support for the
PCI bus present on Prometheus Zorro III to PCI bridge card.
The mppb driver supports the following
hardware:
The mppb device first appeared in
NetBSD 6.0.
The mppb driver was written by
Radoslaw Kujawa
<radoslaw.kujawa@gmail.com>.
The hardware does not support DMA to host memory.
The Prometheus does not support repeating of PCI transactions,
instead if the PCI card demands a retry of transaction, it returns value
0xFFFFFFFF. This is currently not handled by the
mppb driver and will confuse some PCI card
drivers.
