DESCRIPTION
     The p5pb driver provides support for the PCI bus present on various
     devices equipped with the Phase5 PCI bridge.

     The P5PB_CONSOLE option activates the necessary support for the console
     on CyberVisionPPC and BlizzardVisionPPC, allowing the attachment of the
     genfb(4) driver.  3Dfx Voodoo 3 boards installed in G-REX are also sup-
     ported as console by this option in conjuction with the voodoofb(4)
     driver.

     Additional, excessive debugging output is enabled by the P5PB_DEBUG
     option.

           Phase5 BlizzardVisionPPC graphics card

           Phase5 CyberVisionPPC graphics card

           DCE Computer G-REX 1200

HISTORY
     The p5pb device first appeared in NetBSD 6.0.

AUTHORS
     The p5pb driver was written by Radoslaw Kujawa
     <radoslaw.kujawa@gmail.com>.

CAVEATS
     The NetBSD developers don't have access to G-REX hardware or documenta-
     tion.  Support for this device is based on best wishes.

     Support for genfb(4) framebuffer on CVPPC/BVPPC needs more testing.

BUGS
     DMA to host memory is not supported.  This is a driver limitation.
