Jung-uk Kim 36120264ca Bug #11870: FreeBSD hardware lock cleanup fix with multiple opens by a process.
Previously, the lock would get released on the first close by the X Server
(during AIGLX setup), and the Radeon driver would then hang in initialization
due to unexpected failure in DRM calls that required the lock to be held.

Based on a patch by Kostik Belousov.

Eric Anholt c1119b1b09 Replace filp in ioctl arguments with drm_file *file_priv.
As a fallout, replace filp storage with file_priv storage for "unique
identifier of a client" all over the DRM.  There is a 1:1 mapping, so this
should be a noop.  This could be a minor performance improvement, as everything
on Linux dereferenced filp to get file_priv anyway, while only the mmap ioctls
went the other direction.

Eric Anholt c425ad1a34 Previously, drm_get_resource_start() and drm_get_resource_len() would
allocate the resource RF_ACTIVE, pull out the appropriate value, and
    return it. However, allocating large framebuffers RF_ACTIVE would run
    the system out of KVA, and this also left open the possibility of the
    resource getting moved after getting the offset. Instead, when either
    of these are called, allocate the resource if it isn't allocated
    already (non-RF_ACTIVE) and store it in the DRM device, to be cleaned
    up on lastclose.

Eric Anholt c789ea1521 Rename the driver hooks in the DRM to something a little more
understandable: preinit -> load postinit -> (removed) presetup ->
    firstopen postsetup -> (removed) open_helper -> open prerelease ->
    preclose free_filp_priv -> postclose pretakedown -> lastclose
    postcleanup -> unload release -> reclaim_buffers_locked version ->
    (removed)
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.
Tested on: FreeBSD (g200, g400, r200, r128) Linux (r200, savage4)

Eric Anholt b0da5df90a Fix the MGA driver on BSD by passing in the proper chipset flags to the

    of my drm-hook-rename.diff and only compile-tested after that.

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.
http://marc.theaimsgroup.com/?l=dri-devel&m=106625815319773&w=2
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 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.

Eric Anholt a1d9e5abaf Refine the locking of the DRM. Most significant is covering the driver
ioctls with dev_lock, which is a major step toward being able to remove
    Giant. Covers some new pieces (dev->unique*) in the core, and avoids
    one call down into system internals with the drm lock held, which is
    usually bad (FreeBSD LOR #23, #27).
