DESCRIPTION
The ffb is a UPA based color frame buffer, found in some Sun SBus and PCI systems. The ffb driver supports both the Creator/Creator3D, and the Elite3D frame buffers.

There are several versions of the ffb board. The Sun part numbers and board types are:

The ‘Creator’ cards have 5MB of on-board memory, support a maximum graphics resolution of 1280x1024, and are single-buffered.

The ‘Creator3D’ cards have 15MB of on-board memory support a maximum resolution of 1280x1024 double-buffered, and 1920x1360 single-buffered.

The ‘Elite3D’ cards have 15MB of on-board memory, support a maximum resolution of 1280x1024, and are always double-buffered. The ‘Elite3D-m3’ cards have one hardware geometry engine, whereas the ‘Elite3D-m6’ cards have two.

The ‘Series 3’ cards are considerably faster than the ‘Series 1’ and ‘Series 2’ cards.

The ffb driver supports reading EDID data from connected monitors on ‘Series 2’ and ‘Series 3’ cards, and will automatically set a resolution that is supported by both the card and the monitor if the EDID data can be read. This can be overridden for the console frame buffer, by setting the output-device openprom variable. For example, the following openprom command will set the console resolution to 1280x1024 @ 60Hz, which will not be altered by the ffb driver.

    setenv output-device screen:r1280x1024x60

BUGS
It is necessary to blank the video output when reading EDID data.

The ffb driver does not support 3D acceleration.

Not all 13W3 to VGA converters connect 13W3 pin 2 to VGA pin 9. This pin supplies +5V DC to power the monitor EEPROM, even when the monitor is powered off, and is necessary in order to obtain EDID data on some monitors.

Adapters that are known to connect these pins are:

530-2917
    13W3 cable
130-3034
    VGA cable

Adapters that are known not to connect these pins are:

530-2357
    13W3 cable
