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.

Eric Anholt 06cb132e86 - Introduce a new ioctl, DRM_IOCTL_SET_VERSION. This ioctl allows the
server or client to notify the DRM that it expects a certain version of
    the device dependent or device independent interface. If the major
    doesn't match or minor is too large, EINVAL is returned. A major of -1
    means that the requestor doesn't care about that portion of the
    interface. The ioctl returns the actual versions in the same struct.
- Introduce DRM DI interface version 1.1. If the server requests version
    1.1, then the DRM sets the unique itself according to the busid of the
    device it probed, which may then be accessed as normal using getunique.
- Request version 1.1 in libdrm's drmOpenByBusID, allowing the X Server to
    request based on a BusID. Introduce a wrapper for DRM_IOCTL_SET_VERSION
    and bump libdrm minor version.
- Pass the busid in DRIScreenInit if libdrm can handle both a busid and
    name. This allows drmOpenByBusID to be used to find the DRM instead of
    just the driver name, which allows us in the future to tie a DRM more
    strongly to the device it probed to. Introduce a function
    DRICreatePCIBusID which creates a busid in the form pci:oooo:bb:dd.f
    similar to linux's pci_name() function. This matches the format used by
    the DRM in version 1.1. libdrm knows how to match both this format and
    the old PCI🅱️d:f format.
- Use the new DRICreatePCIBusID function in the *_dri.c to request the new,
    more exact busid format.

Eric Anholt 929536172c Stylistic preparation for SMPng locking work: DRM_LOCK/DRM_UNLOCK have side
effects, so make them look like functions (add parenthesis).

Eric Anholt a6b84f73e1 Mostly whitespace cleanups and style(9) fixes focused on "if(" -> "if ("
Change some nearby memset()s to bzero()s or to calloc allocations to
    take advantage of M_ZERO). Reverse some error tests to reduce high
    levels of indentation. Move the sg_cleanup() call out of the maplist
    loop in DRM(takedown)-- I can't see any need for it to be inside.

Eric Anholt ad78a613a4 - Remove $FreeBSD$ tags as they weren't too useful and merges are now being
done through perforce.
- Add copyright headers to drm_os_*bsd.h, still need to research the other
    copyright-less files better.

Eric Anholt a147df879b Remove more gamma DMA infrastructure. Most of this code was copied straight
from linux, so it could be added back if some driver needed it in the
    future.

Eric Anholt 01178567eb Remove more gamma DMA code. This isn't all of it, but it's a major portion. 2003-04-24 06:19:54 +00:00
Eric Anholt bcd527ee71 Remove a bunch of dead code and fix spelling of a couple of comments. 2003-04-24 04:50:07 +00:00
Eric Anholt 0bd0dd2300 Merge back from FreeBSD-current, adding FreeBSD ID tags to aid future
merging. Also includes an update to radeon PCI IDs.
