Re: XF68_FBDev under MkLinux?

Perhaps I misunderstand.  What ioctls are you proposing to use?
MkLinux (Linux and Mach sides combined) supports ioctls like
VC_GETMODE, VC_SETMODE, VC_INQMODE, VC_SETCMAP, and VC_GETCMAP.

These ioctls.

However, I believe that the Mach drivers will currently only allow you
to use the one video mode (width, height, depth, etc.) in effect from
the MacOS side.  That one mode should be revealed by the video ioctls.

Would that restriction cause a problem?

No problem. That's very similar to `mode "default"' with XF68_FBDev.

  2. Adopt XF68_FBdev so it can use the MkLinux video mode ioctl stuff.

vmode ioctl stuff?  Since when does MkLinux support detecting or changing
video modes?  This is where we're going to run into trouble either way.

Doesn't the stuff in <asm/vc_ioctl.h> come from MkLinux?

Maybe.  I'm not saying the linux server part doesn't have the support,
just that the mach kernel drivers don't, AFAIK.  :-)
