ibook radeonfb mirroring
I'm trying to make my ibook mirror its video output on the secondary
CRTC of the Radeon Mobility M7 LW (7500). I tried using the m7mirror.c
srcs found on the net, modified from m3mirroc.c on
This basically do ioctl(fd, FBIO_RADEON_SET_MIRROR, &value);
This does not work on my 2.6.3-rc2-ben1 kernel. After looking in the
sources (drivers/video/aty/radeon_base.c), I found the following (in
the ioctl function):
Is this normal ? As far as I understand this means that it is not
possible to set mirroring for mobility cards ? Why ?
I must say that I can clone display using a superposed xinerama layout,
but I lose 3D and mouse is only present on the flat panel.
