      drm: convert drm_ioctl to unlocked_ioctl · ed8b6704
      Arnd Bergmann 提交于
      drm_ioctl is called with the Big Kernel Lock held,
      which shows up very high in statistics on vfs_ioctl.
      
      Moving the lock into the drm_ioctl function itself
      makes sure we blame the right subsystem and it gets
      us one step closer to eliminating the locked version
      of fops->ioctl.
      
      Since drm_ioctl does not require the lock itself,
      we only need to hold it while calling the specific
      handler. The 32 bit conversion handlers do not
      interact with any other code, so they don't need
      the BKL here either and can just call drm_ioctl.
      
      As a bonus, this cleans up all the other users
      of drm_ioctl which now no longer have to find
      the inode or call lock_kernel.
      
      [airlied: squashed the non-driver bits
      of the second patch in here, this provides
      the flag for drivers to use to select unlocked
      ioctls - but doesn't modify any drivers].

      drm: reorganise drm tree to be more future proof. · c0e09200
      Dave Airlie 提交于
      With the coming of kernel based modesetting and the memory manager stuff,
      the everything in one directory approach was getting very ugly and
      starting to be unmanageable.
      
      This restructures the drm along the lines of other kernel components.
      
      It creates a drivers/gpu/drm directory and moves the hw drivers into
      subdirectores. It moves the includes into an include/drm, and
      sets up the unifdef for the userspace headers we should be exporting.

      drm: fix driver deadlock with AIGLX and reclaim_buffers_locked · 040ac320
      Thomas Hellstrom 提交于
      Bugzilla Bug #9457
      
      Add refcounting of user waiters to the DRM hardware lock, so that we can use
      DRM_LOCK_CONT flag more conservatively.
      
      Also add a kernel waiter refcount that if nonzero transfers the lock for the
      kernel context when it is released. This is useful when waiting for idle and can be used for very simple fence object driver implementations for the new memory manager

      drm: rename driver hooks more understandably · 22eae947
      Dave Airlie 提交于
      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)

      drm: lindent the drm directory. · b5e89ed5
      Dave Airlie 提交于
      I've been threatening this for a while, so no point hanging around.
      This lindents the DRM code which was always really bad in tabbing department.
      I've also fixed some misnamed files in comments and removed some trailing
      whitespace.

      Initial git repository build. I'm not bothering with the full history,
      even though we have it. We can create a separate "historical" git
      archive of that later if we want to, and in the meantime it's about
      3.2GB when imported into git - space that would just make the early
      git days unnecessarily complicated, when we don't have a lot of good
      infrastructure for it.
      
      Let it rip!
