That's what I did. For instance,

  strace m3mirror crt:1 lcd:1

shows

  ioctl(3, 0x40044001, 0x7ffff98c)

I don't know it that's fine.

Me neither; I'd have to work out what the _IOW macro expands to in that
case. What kernel headers version do you have installed (f.i. Debian ships
2.5.999 which won't match your 2.4.24 kernel too well)?

m3mirror + 2.4.24

[Jean-Jacques Levy]

I just upgraded from 2.4.20-pre7-ben0 to 2.4.24-ben1 on my Titanium
7410, 500MHz. Everything goes smoothly, except following:

   m3mirror crt:1 lcd:1

which no longer works properly. The command runs silently with no
error messages and no effect. However m3mirror crt:0 clear the
external video. In /usr/src/linux/.config, I do have

   CONFIG_PMAC_PBOOK=y

What's was wrong in my installation?

Best to all, -JJ-

The kernel ioctls for m3mirror might have changed; recompile m3mirror
against new kernel headers?

Right now, I think the headers are set by:

  /usr/include/linux -> /usr/src/linux/include/linux
  /usr/include/asm -> /usr/src/linux/include/asm
  /usr/src/linux/include/asm -> /usr/src/linux/include/asm-ppc

I hope it's correct.

And /usr/src/linux is the 2.4.24 tree? (check include/linux/version.h)

Can't find include/linux/version.h. Is it missing ?

The /usr/src/linux is indeed Linux 2.4.24-ben1.
