ZZ9K(4)

NAME
zz9k - MNT ZZ9000 graphics card driver

SYNOPSIS
zz9k* at zbus?
zzfb* at zz9k?
options ZZFB_CONSOLE
zz* at zz9k?
zzax* at zz9k?
zzusb* at zz9k?

DESCRIPTION
The zz9k driver provides support for the MNT ZZ9000 graphics card and ethernet interface. Each driver can be individually enabled or disabled. However, all ZZ9000 drivers depend on the zz9k* as the root to work.

The zzfb* wscons(4) driver implements blitter-accelerated support for the boot console. Support for an unaccelerated X11 framebuffer is also available via the wsfb(4) driver.

The zz* driver implements the ZZ9000 ethernet interface.

There is also provision for adding ZZ9000AX audio card support as zzax* and the USB port support as zzusb* at a later time. None of these are functional yet.

HISTORY
The zz9k device first appeared in NetBSD 10.0.

AUTHORS
-nosplit The zz9k driver was written by Alain Runa <alain74@gmx.net> and was inspired by the original ZZ9000 drivers for AmigaOS.

CAVEATS
For the ZZ9000 to assume the boot console, the user has to explicitly set the FBZZ_CONSOLE option in the kernel config file.

Currently, the video mode is hard-coded to 1280x720 at 8 bpp for the console emulation and 16 bpp for the framebuffer used by X11. Resolutions and color depths can be individually changed in the zz9k_fb.c source code. Please follow the source code comments.

The zz* ethernet driver is considered experimental. As the MAC address is not stored permanently in the card, it will use its default address. This should not impose any problem unless two ZZ9000 will be used in the same LAN. Please configure the desired link address for the zz0 interface in rc.conf or in the /etc/ifconfig.zz0 file, to avoid a MAC address collision.

The zzax* audio card driver is not functional yet. Only a basic skeleton source code is available for a possible later implementation.

The zzusb* USB driver is not functional yet. Only a basic skeleton source code is available for a possible later implementation.

BUGS
None known.
