Hi!

Following up on Felix's mail on this issue:

Is it a correct understanding that for a 32-bit userspace app to work with
an AMD64 64bit drm, the following needs to be fulfilled:

* IOCTL args must have the same size and layout in 64- and 32 bit models,
in particular pointers to user space areas need to be 64-bit padded.

* private parts of the SAREA needs to have the same size and layout in 64-
and 32-bit models.

Any enlightment here would be greatly appreciated.

/Thomas
