Hello,
I've committed a generic framebuffer driver a couple days
ago, it
supports the usual wsdisplay stuff like virtual consoles and
might
serve as an intermediate solution until someone who has
access to the
hardware adds wsdisplay support to those sbus driver still
without.
genfb can attach to pci or sbus
When attaching to pci it needs framebuffer parameters passed
as
properties, so far only macppc supports this, adding it to -
say -
sparc64 is trivial though.
With SBus no such thing is necessary, it should use whatever
the
firmware set up.
The problem is that in the SBus case there is no generic way
to access
palette registers so in 8 bit things will be ugly. There's
none in the
PCI case either but on macppc we can use OpenFirmware to do
the
gruntwork.
What I'd like to see tested is:
- - genfb at sbus on sparc(64) with framebuffers we don't
have native
wsdisplay drivers for, like cg14, bwtwo etc.
- - genfb at pci on macppc, it works fine on my machines but
it needs to
be tested on things like /chaos/control
- - XFree86 using the wsfb driver. On macppc native PCI XF86
drivers
should work too but since genfb doesn't support the /dev/fb*
interface
XFree's SBus drivers won't work.
genfb at pci on anything else than macppc won't work because
of missing
MD code to pass framebuffer parameters.
have fun
Michael
