GRFCL(4)             NetBSD/amiga Kernel Interfaces Manual            GRFCL(4)


NAME

     grfcl -- 8/16/24/32-bit color graphics driver


SYNOPSIS

     grfcl* at zbus0
     grf3 at grfcl?
     ite3 at grf3


DESCRIPTION

     The grfcl device driver supports graphics boards with the Cirrus Logic
     chipset.  It supports the minimal ioctl's needed to run X11.


HARDWARE

     The grfcl interface supports the following ZorroII/III expansion cards:

           Picasso II/II+  A Zorro II only card with the Cirrus Logic 5426,
                           5428 or 5429 chipset. From Village Tronic, manufac-
                           turer 2167, product 11 for the memory base and 12
                           for the register base (if your board has a product
                           of 13, it is in segmented mode which is not sup-
                           ported by NetBSD).  This board supports 8/15/16/24
                           bit graphics modes.

           Picasso IV      A Zorro II/III card with the Cirrus Logic 5446
                           chipset. From Village Tronic, manufacturer 2167, in
                           Zorro II mode with the product 21 for the memory
                           base1, 22 for the memory base2 and 23 for the reg-
                           ister base, in Zorro III mode with the product 24
                           for the entire board.  This board supports
                           8/15/16/24 bit graphics modes.

           Piccolo         A Zorro II/III card with the Cirrus Logic 5426
                           chipset. From IBH, manufacturer 2195, product 5 for
                           the memory base and 6 for the register base.  This
                           board supports 8/15/16/24 bit graphics modes.

           Piccolo SD64    A Zorro II/III card with the Cirrus Logic 5434
                           chipset. From IBH, manufacturer 2195, product 10
                           for the memory base and 11 for the register base.
                           This board supports 8/15/16/24/32 bit graphics
                           modes.

           Spectrum        A Zorro II/III card with the Cirrus Logic 5426
                           chipset. From GVP, manufacturer 2193, product 1 for
                           the memory base and 2 for the register base.  This
                           board supports 8/15/16/24 bit graphics modes.

BUGS

     grfcl will not work with Zorro II cards in the segmented mode and it does
     not support the sync-on-green flag from amiga/grfconfig(8).
