51 * DOC: getunique and setversion story
52 *
53 * BEWARE THE DRAGONS! MIND THE TRAPDOORS!
54 *
55 * In an attempt to warn anyone else who's trying to figure out what's going
56 * on here, I'll try to summarize the story. First things first, let's clear up
57 * the names, because the kernel internals, libdrm and the ioctls are all named
58 * differently:
59 *
60 * - GET_UNIQUE ioctl, implemented by drm_getunique is wrapped up in libdrm
61 * through the drmGetBusid function.
62 * - The libdrm drmSetBusid function is backed by the SET_UNIQUE ioctl. All
63 * that code is nerved in the kernel with drm_invalid_op().
64 * - The internal set_busid kernel functions and driver callbacks are
65 * exclusively use by the SET_VERSION ioctl, because only drm 1.0 (which is
66 * nerved) allowed userspace to set the busid through the above ioctl.
67 * - Other ioctls and functions involved are named consistently.
68 *
69 * For anyone wondering what's the difference between drm 1.1 and 1.4: Correctly
70 * handling pci domains in the busid on ppc. Doing this correctly was only
71 * implemented in libdrm in 2010, hence can't be nerved yet. No one knows what's
72 * special with drm 1.2 and 1.3.
73 *
74 * Now the actual horror story of how device lookup in drm works. At large,
75 * there's 2 different ways, either by busid, or by device driver name.
76 *
77 * Opening by busid is fairly simple:
78 *
79 * 1. First call SET_VERSION to make sure pci domains are handled properly. As a
80 * side-effect this fills out the unique name in the master structure.
81 * 2. Call GET_UNIQUE to read out the unique name from the master structure,
82 * which matches the busid thanks to step 1. If it doesn't, proceed to try
83 * the next device node.
84 *
85 * Opening by name is slightly different:
86 *
87 * 1. Directly call VERSION to get the version and to match against the driver
88 * name returned by that ioctl. Note that SET_VERSION is not called, which
89 * means the the unique name for the master node just opening is _not_ filled
90 * out. This despite that with current drm device nodes are always bound to
91 * one device, and can't be runtime assigned like with drm 1.0.
92 * 2. Match driver name. If it mismatches, proceed to the next device node.
93 * 3. Call GET_UNIQUE, and check whether the unique name has length zero (by
94 * checking that the first byte in the string is 0). If that's not the case
95 * libdrm skips and proceeds to the next device node. Probably this is just
96 * copypasta from drm 1.0 times where a set unique name meant that the driver
97 * was in use already, but that's just conjecture.
98 *
99 * Long story short: To keep the open by name logic working, GET_UNIQUE must
100 * _not_ return a unique string when SET_VERSION hasn't been called yet,
101 * otherwise libdrm breaks. Even when that unique string can't ever change, and
102 * is totally irrelevant for actually opening the device because runtime
103 * assignable device instances were only support in drm 1.0, which is long dead.
104 * But the libdrm code in drmOpenByName somehow survived, hence this can't be
105 * broken.

792 * DOC: driver specific ioctls
793 *
794 * First things first, driver private IOCTLs should only be needed for drivers
795 * supporting rendering. Kernel modesetting is all standardized, and extended
796 * through properties. There are a few exceptions in some existing drivers,
797 * which define IOCTL for use by the display DRM master, but they all predate
798 * properties.
799 *
800 * Now if you do have a render driver you always have to support it through
801 * driver private properties. There's a few steps needed to wire all the things
802 * up.
803 *
804 * First you need to define the structure for your IOCTL in your driver private
805 * UAPI header in ``include/uapi/drm/my_driver_drm.h``::
806 *
807 * struct my_driver_operation {
808 * u32 some_thing;
809 * u32 another_thing;
810 * };
811 *
812 * Please make sure that you follow all the best practices from
813 * ``Documentation/process/botching-up-ioctls.rst``. Note that drm_ioctl()
814 * automatically zero-extends structures, hence make sure you can add more stuff
815 * at the end, i.e. don't put a variable sized array there.
816 *
817 * Then you need to define your IOCTL number, using one of DRM_IO(), DRM_IOR(),
818 * DRM_IOW() or DRM_IOWR(). It must start with the DRM_IOCTL\_ prefix::
819 *
820 * ##define DRM_IOCTL_MY_DRIVER_OPERATION \
821 * DRM_IOW(DRM_COMMAND_BASE, struct my_driver_operation)
822 *
823 * DRM driver private IOCTL must be in the range from DRM_COMMAND_BASE to
824 * DRM_COMMAND_END. Finally you need an array of &struct drm_ioctl_desc to wire
825 * up the handlers and set the access rights::
826 *
827 * static const struct drm_ioctl_desc my_driver_ioctls[] = {
828 * DRM_IOCTL_DEF_DRV(MY_DRIVER_OPERATION, my_driver_operation,
829 * DRM_AUTH|DRM_RENDER_ALLOW),
830 * };
831 *
