Add basic PCI support for amiga port.
Add missing bus_space(9) methods needed for MI PCI. Add p5pb(4) - Phase5 PCI bridge driver (and the man page). Add quirks table to zbus(4) - needed for p5pb. Change approved by phx.

.Cd "genfb* at pci?"
|
||||
.Sh DESCRIPTION
|
||||
The
|
||||
.Nm
|
||||
driver provides support for the PCI bus present on BlizzardVisionPPC and
|
||||
CyberVisionPPC graphics cards.
|
||||
.Sh HARDWARE
|
||||
The
|
||||
.Nm
|
||||
driver supports the following hardware:
|
||||
.Bl -tag -width "BLIZZARDVISIONPPC" -offset indent
|
||||
.It Em BLIZZARDVISIONPPC
|
||||
Phase5 BlizzardVisionPPC graphics card.
|
||||
.El
|
||||
.Bl -tag -width "BLIZZARDVISIONPPC" -offset indent
|
||||
.It Em CYBERVISIONPPC
|
||||
Phase5 CyberVisionPPC graphics card.
|
||||
.El
|
||||
.Sh SEE ALSO
|
||||
.Xr pm2fb 4 ,
|
||||
.Xr genfb 4 ,
|
||||
.Xr pci 4
|
||||
.Sh HISTORY
|
||||
The
|
||||
.Nm
|
||||
device first appeared in
|
||||
.Nx 6.0 .
|
||||
.Sh AUTHORS
|
||||
.An -nosplit
|
||||
The
|
||||
.Nm
|
||||
driver was written by
|
||||
.An Radoslaw Kujawa Aq radoslaw.kujawa@gmail.com .
|
||||
.Sh BUGS
|
||||
Current version of this driver depends on PCI bus setup and enumeration
|
||||
done by the firmware.
|
||||
.Pp
|
||||
The driver will not attach at all, if there is no AutoConfig entry
|
||||
for CVPPC/BVPPC card (Zorro product ID 110). Some firmware revisions
|
||||
are known not to create this entry.
|
||||
.Pp
|
||||
It is not (yet) possible to use the CVPPC/BVPPC as a console.
