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
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.
