- .Dt MACHFB 4 sparc64
- .Os
- .Sh NAME
- .Nm machfb
- .Nd "accelerated color frame buffer"
- .Sh SYNOPSIS
- .Cd "device machfb"
- .Sh DESCRIPTION
- The
- .Tn ATI Mach64
- family of chips are color frame buffers with graphics acceleration.
- The
- .Nm
- driver interfaces those frame buffers with the
- .Xr syscons 4
- console driver.
- .Pp
- .Tn ATI Mach64
- chips are very common as low-end graphics chips in
- .Tn PCI
- based
- .Tn UltraSPARC
- systems.
- They are found on-board in
- .Tn Sun Blade 100 ,
- .Tn Sun Blade 150 ,
- .Tn Sun Ultra 5
- and
- .Tn Sun Ultra 10
- as well as on
- .Tn Sun
- OEM mainboards like the
- .Tn Sun AXe .
- They are also used on add-on cards like the
- .Tn Sun PGX
- and
- .Tn Sun PGX64 .
- .Pp
- The
- .Nm
- driver requires the chip which it is supposed to drive to be also
- supported by the
- .Tn Open Firmware ,
- either by a built-in FCode driver package of the on-board firmware
- or by additional FCode on the add-on card.
- As a matter of course
- .Tn UltraSPARC
- systems with an on-board
- .Tn ATI Mach64 chip
- also have a built-in FCode driver package for this chip.
- There are also mainboards like the
- .Tn Sun AX1105
- and
- .Tn Sun AXi
- boards however,
- which have built-in FCode for certain
- .Tn ATI Mach64
- chips although they are not equipped with an on-board one.
- Mainboards with built-in FCode for certain
- .Tn ATI Mach64
- chips can be used with any add-on card which is based on one of those
- chips,
- including cards which are equipped with x86 firmware and intended for
- use in PCs.
- Otherwise an add-on card which comes with its own FCode like the
- .Tn Sun PGX
- or
- .Tn Sun PGX64
- has to be used.
- .Sh HARDWARE
- The
- .Nm
- driver provides support for the following chips:
