Eric Anholt 66c9e3053f - Tie the DRM to a specific device: setunique no longer succeeds when given
a busid that doesn't correspond to the device the DRM is attached to.
    This is a breaking of backwards-compatibility only for the
    multiple-DRI-head case with X Servers that don't use interface 1.1.
- Move irq_busid to drm_irq.h and make it only return the IRQ for the
    current device. Retains compatibility with previous X Servers, cleans
    up unnecessary code. This means no irq_busid on !__HAVE_IRQ, but can be
    changed if necessary.
- Bump interface version to 1.2. This version when set signifies that the
    control ioctl should ignore the irq number passed in and enable the
    interrupt handler for the attached device. Otherwise it errors out when
    the passed-in irq is not equal to the device's.
- Store the highest version the interface has been set to in the device.
- Fix a recursion on DRM_LOCK in irq_uninstall on FreeBSD. This leaves
    irq_uninstall being done without the lock in some cases, but it was
    racey anyways.

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
