NAME

     mppb -- Prometheus PCI bridge driver


SYNOPSIS

     mppb* at zbus0
     pci* at mppb?


DESCRIPTION

     The mppb driver provides support for the PCI bus present on Prometheus
     Zorro III to PCI bridge card.


HARDWARE

     The mppb driver supports the following hardware:

           PROMETHEUS  Matay Prometheus. Manufacturer 44359, product 1.


SEE ALSO

     pci(4)


HISTORY

     The mppb device first appeared in NetBSD 6.0.


AUTHORS

     The mppb driver was written by Radoslaw Kujawa
     <radoslaw.kujawa@gmail.com>.


BUGS

     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.
