Power9100 accelerated frame buffer
pnozz0 at sbus? slot ? offset ?
The pnozz
is a color frame buffer with
graphics acceleration, embedded in the Tadpole SPARCbook 3GS, 3GX, 3TX, and
3XP laptops. It is based on the Weitek Power9100 video processor and an IBM
RGB525 RAMDAC.
If the
sparc/tctrl(4) device
is also configured, the pnozz
will be powered down
when the lid of the laptop is closed or the screen is blanked.
Support for the pnozz
first appeared in
NetBSD 1.6.
There is currently no way to switch back and forth from the onboard display to the external connector. It is not possible to change resolutions or color depth.
