Hi, 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 http://penguinppc.org/~benh/.
This basically do ioctl(fd, FBIO_RADEON_SET_MIRROR, &value); on /dev/fb0. 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): case FBIO_RADEON_SET_MIRROR: if (!rinfo->is_mobility) return -EINVAL; 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. THX -- Cedric "[Of course] I'm French!
