[SPARC64/COMPAT]: Add some compat ioctl for ppdev
Browse files Browse the repository at this point in the history
The following patch adds some ioctls to include/linux/compat_ioctl.h
to allow using ppdev from the 32 bit user space on sparc64.

This patch also adds the PPDEV option in the sparc64 menu, near Parallel
printer support in the 'General machine setup' submenu.

All those ioctls seem to be compatible, since (correct me if I'm wrong)
they dont use the 'long' type. See include/linux/ppdev.h.

The application I used to test the new ioctls only used the following:
PPEXCL
PPCLAIM
PPNEGOT
PPGETMODES
PPRCONTROL
PPWCONTROL
PPDATADIR
PPWDATA
PPRDATA

But I beleive that the other ioctls will work fine.

If you have more than 8 printers, you need to increase the LP_NO
macro in lp.c and the PARPORT_MAX macro in parport.h.

---help---
Saying Y to this adds support for /dev/parport device nodes. This
is needed for programs that want portable access to the parallel
port, for instance deviceid (which displays Plug-and-Play device
IDs).

This is the parallel port equivalent of SCSI generic support (sg).
It is safe to say N to this -- it is not needed for normal printing
or parallel port CD-ROM/disk support.

To compile this driver as a module, choose M here: the
module will be called ppdev.

If unsure, say N.
