Alan Hourihane b6b270a260 Given that BenH says using the sysdev approach for DRM is bogus, I'll yank
the code for it, rather than introducing something that isn't going to
    work 100% of the time.

Ian Romanick 72cfc797b5 Adds support for PCI cards to MGA DRM
This patch adds serveral new ioctls and a new query to get_param query to
    support PCI MGA cards.
Two ioctls were added to implement interrupt based waiting. With this
    change, the client-side driver no longer needs to map the primary DMA
    region or the MMIO region. Previously, end-of-frame waiting was done by
    busy waiting in the client-side driver until one of the MMIO registers
    (the current DMA pointer) matched a pointer to the end of primary DMA
    space. By using interrupts, the busy waiting and the extra mappings are
    removed.
A third ioctl was added to bootstrap DMA. This ioctl, which is used by the
    X-server, moves a *LOT* of code from the X-server into the kernel. This
    allows the kernel to do whatever needs to be done to setup DMA buffers.
    The entire process and the locations of the buffers are hidden from
    user-mode.
Additionally, a get_param query was added to differentiate between G4x0
    cards and G550 cards. A gap was left in the numbering sequence so that,
    if needed, G450 cards could be distinguished from G400 cards. According
    to Ville Syrjälä, the G4x0 cards and the G550 cards handle
    anisotropic filtering differently. This seems the most compatible way
    to let the client-side driver know which card it's own. Doing this very
    small change now eliminates the need to bump the DRM minor version
    twice.

A number of ioctl handlers in linux-core were also modified so that they
    could be called in-kernel. In these cases, the in-kernel callable
    version kept the existing name (e.g., drm_agp_acquire) and the ioctl
    handler added _ioctl to the name (e.g., drm_agp_acquire_ioctl).
This patch also replaces the drm_agp_do_release function with
    drm_agp_release. drm_agp_release (drm_core_agp_release in the previous
    patch) is very similar to drm_agp_do_release, and I saw no reason to
    have both.
This commit *breaks the build* on BSD. Eric said that he would make the
    required updates to the BSD side soon.

Eric Anholt 9cad6fb4e0 Bugzilla #3217: Create a new __drm_pci_free which is used internally in
linux-core to free pci memory without freeing the structure. Linux-core
    internals often create pci dma handle structures on the stack due to
    the lack of a drm_local_map_t to store them in properly. Fix the
    original drm_pci_free to actually free the dma handle structure instead
    of leaking it.

Alan Hourihane 45f1db8db9 Re-implement the power management.
There's two choices when fb is or isn't loaded as we treat ourselves as a
    PCI driver in the latter case.
If we are a PCI driver, then register the suspend/resume functions
    directly. If not, then we register as a sysdev and pick up the
    suspend/resume actions and pump them down into a generic *power
    function.
It'll be nice when this little mess is sorted out with regard to being a
    real PCI driver ;-/

Ian Romanick 4a84416c45 Modify drm_driver::device_is_agp to return a tri-state value to indicate
that a device absolutely is, absolutely is not, or may or may not be
    AGP. Modify the i915 DRM to use this to force all i9x5 devices to be
    "AGP" (even the PCI-e devices).

Ian Romanick e051cd19c0 Added device_is_agp callback to drm_driver. This function is called by the
platform-specific drm_device_is_agp function. Added implementation of
    this function the the Linux-specific portion of the MGA driver to
    detect PCI G450 cards. Added code to the Linux-specific portion of the
    generic DRM layer to not initialize AGP infrastructure if the card is
    not AGP (this matches what already existed in BSD).
Bumped the driver date and the driver patch-level for MGA.
This mostly fixes bugzilla #3248. The BSD side still needs an
    implementation of mga_driver_device_is_agp.

Eric Anholt ec111d70fe Convert BSD code to mostly use bus_dma, the dma abstraction for dealing
with IOMMUs and such. There is one usage of the forbidden vtophys()
    left in drm_scatter.c which will be fixed up soon. This required a KPI
    change for drm_pci_alloc/free() to return/use a drm_dma_handle_t that
    keeps track of os-specific bits, rather than just passing around the
    vaddr/busaddr/size.

Eric Anholt 080a547d4d - Implement drm_initmap, and extend it with the resource number to help
FreeBSD. Add drm_get_resource_{start|len} so linux-specific stuff
    doesn't need to be in shared code.
- Fix mach64 build by using __DECONST to work around passing a const
    pointer to useracc, which is unfortunately not marked const.
- Get rid of a lot of maplist code by not having dev->maplist be a pointer,
    and by sticking the link entries directly in drm_local_map_t rather
    than having a separate structure for the linked list.
- Factor out map uninit and removal into its own routine, rather than
    duplicating in both drm_takedown() and drm_rmmap().
- Hook up more driver functions, and correct FreeBSD-specific bits of
    radeon_cp.c, making radeon work.
- Baby steps towards using bus_space as we should.
