|  | - Comment out the "is this mapping/bufs in allocated AGP" bits in BSD
    because they break mga (which uses AGP allocation that doesn't track
    entries). It's not a security issue when we still have the related
    ioctls marked root-only.
- Apply some power-of-two alignment restrictions to hopefully avoid some
    panicing in bad cases of drm_pci_alloc() on FreeBSD.
- Add verbosity to some error handling that I found useful while debugging. |

    return it. However, allocating large framebuffers RF_ACTIVE would run
    the system out of KVA, and this also left open the possibility of the

    of these are called, allocate the resource if it isn't allocated

postinit and version were replaced with generic code in the Linux DRM
    (drivers now set their version numbers and description in the driver
    structure, like on BSD). postsetup wasn't used at all. Fixes the savage
    hooks for initializing and tearing down mappings at the right times.
    Testing involved at least starting X, running glxgears, killing
    glxgears, exiting X, and repeating.

|  | i915 has been disabled for the moment, rather than working around
    linux-specific code in the shared dir. | 
|  | 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.
Xorg bug: 3259 Reviewed by: Eric Anholt | 
|  | There were two problems. First, the 'warp' and 'primary' pointers weren't
    cleared, so mga_do_cleanup_dma, which gets called multiple times, would
    try to ioremapfree them multiple times. This resulted in the new error
    messages to syslog. The second problem was the, since the dev_private
    structure isn't reallocated and cleaned out in mga_do_init_dma, when
    the server is reloaded idle-waits would wait for impossible values.
I have given this patch some more riggorous testing. This includes:
- Load module, start server, run GL app, stop server, unload module.
- Load module, start server, run GL app, stop server, unload module, reload
    module, restart server, run GL app.
- Load module, start server, run GL app, stop server, restart server, run
    GL app, stop server, unload module.
In all three cases, everything worked as expected. Please let me know if
    there are any further regressions with this patch.

|  | is now allocated (and partially filled in) by the new
    mga_driver_preinit function.
This allows the driver to detect the type of card (i.e., G200 class vs.
    G400 class) on its own. The chipset value passed to mga_dma_init is now
    ignored. This same technique is used by the radeon DRM.
As a result of this, mga_driver_pretakedown was converted to
    mga_driver_postcleanup. This routine gets called in some other places
    than might be expected, and it sets the dev_private pointer to NULL.

|  | 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

    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.
