+ * On IRIX, /dev/graphics is [10, 146]
+ * /dev/opengl is [10, 147]
+ *
+ * From a mail with Mark J. Kilgard, /dev/opengl and /dev/graphics are
+ * the same thing, the use of /dev/graphics seems deprecated though.
+ *
+ * The reason that the original SGI programmer had to use only one
+ * device for all the graphic cards on the system will remain a
+ * mistery for the rest of our lives. Why some ioctls take a board
+ * number and some others not? Mistery. Why do they map the hardware
+ * registers into the user address space with an ioctl instead of
+ * mmap? Mistery too. Why they did not use the standard way of
+ * making ioctl constants and instead sticked a random constant?
+ * Mistery too.
+ *
+ * We implement those misterious things, and tried not to think about
+ * the reasons behind them.

+ * shmiq.c: shared memory input queue driver
+ * written 1997 Miguel de Icaza (miguel@nuclecu.unam.mx)
+ *
+ * We implement /dev/shmiq, /dev/qcntlN here
+ * this is different from IRIX that has shmiq as a misc
+ * streams device and the and qcntl devices as a major device.
+ *
+ * minor number 0 implements /dev/shmiq,
+ * any other number implements /dev/qcntl${minor-1}
+ *
+ * /dev/shmiq is used by the X server for two things:
+ *
+ * 1. for I_LINK()ing trough ioctl the file handle of a
+ * STREAMS device.
+ *
+ * 2. To send STREAMS-commands to the devices with the
+ * QIO ioctl interface.
+ *
+ * I have not yet figured how to make multiple X servers share
+ * /dev/shmiq for having different servers running. So, for now
+ * I keep a kernel-global array of inodes that are pushed into
+ * /dev/shmiq.
+ *
+ * /dev/qcntlN is used by the X server for two things:
+ *
+ * 1. Issuing the QIOCATTACH for mapping the shared input
+ * queue into the address space of the X server (yeah, yeah,
+ * I did not invent this interface).
+ *
+ * 2. used by select. I bet it is used for checking for events on
+ * the queue.
+ *
+ * Now the problem is that there does not seem anything that
+ * establishes a connection between /dev/shmiq and the qcntlN file. I
+ * need an strace from an X server that runs on a machine with more
+ * than one keyboard. And this is a problem since the file handles
+ * are pushed in /dev/shmiq, while the events should be dispatched to
+ * the /dev/qcntlN device.
+ *
+ * Until then, I just allow for 1 qcntl device.

+ *
+ * This file contains the implementation of /dev/usemaclone,

+ *
+ * /dev/usemaclone is used to create a new semaphore device, and then
+ * the semaphore is manipulated via ioctls.
+ *
+ * At least for the zero-contention case, lock set and unset as well
+ * as semaphore P and V are done in userland, which makes things a
+ * little bit better. I suspect that the ioctls are used to register
+ * the process as blocking, etc.
+ *
+ * Much inspiration and structure stolen from Miguel's shmiq work.
