Re: XF68_FBDev under MkLinux?

Geert--

Recent (non-official) MkLinux kernels support /dev/adbmouse (busmouse
emulation).  GPM works with it, so I suspect that XF68_FBdev would as
well.  Choice #2 does seem the least amount of work.

One question--would acceleration would still require framebuffer
devices?

To reduce development efforts, it may be better to start using XF68_FBdev under
MkLinux too. That way plain XFree86 will work on both MkLinux/PPC and
Linux/PPC.

I see two solutions:

  1. Add frame buffer devices to MkLinux. This requires many kernel changes to
     MkLinux and forces people to upgrade their kernel.

  2. Adopt XF68_FBdev so it can use the MkLinux video mode ioctl stuff. This
     requires no kernel changes. In XF68_FBDev, the video ioctl and mmap stuff
     has to be changed slightly.

I think the second solution is the least amount of work.

Another thing is keyboard and mouse (ADB) handling. Xpmac uses the plain
/dev/adb device, while XF68_FBDev takes the standard Linux keyboard input and
uses the adbmouse driver. I assume keyboard won't be a problem. But the mouse
requires the adbmouse driver.
