      drm: Try loading builtin EDIDs first · 9066f83c
      Chris Wilson authored
      If the firmware is not builtin and userspace is not yet running, we can
      stall the boot process for a minute whilst the firmware loader times
      out. This is contrary to expectations of providing a builtin EDID!
      
      In the process, we can rearrange the code to make the error handling
      more resilient and prevent gcc warning about unitialised variables along
      the error paths.
      
      v2: Load builtins first, fix gcc second (Jani) and cosmetics (Ville).
      v3: Verify that we do not read beyond the end of the fwdata (Ville)

      drm: move device unregistration into drm_dev_unregister() · c3a49737
      David Herrmann authored
      Analog to drm_dev_register(), we now provide drm_dev_unregister() which
      does the reverse. drm_dev_put() is still in place and combines the calls
      to drm_dev_unregister() and drm_dev_free() so buses don't have to change.
      
      *_get() and *_put() are used for reference-counting in the kernel.
      However, drm_dev_put() definitely does not do any kind of ref-counting.
      Hence, use the more appropriate *_register(), *_unregister(), *_alloc()
      and *_free() names.

      drm: introduce drm_dev_free() to fix error paths · 0dc8fe59
      David Herrmann authored
      The error paths in DRM bus drivers currently leak memory as they don't
      correctly revert drm_dev_alloc(). Introduce drm_dev_free() to free DRM
      devices which haven't been registered, yet.
      
      We must be careful not to introduce any side-effects with cleanups done in
      drm_dev_free(). drm_ht_remove(), drm_ctxbitmap_cleanup() and
      drm_gem_destroy() are all fine in that regard.

      drm: move drm_lastclose() to drm_fops.c · 1c8887dd
      David Herrmann authored
      Try to keep all functions that handle DRM file_operations in drm_fops.c
      so internal helpers can be marked static later.
      
      This makes the split between the 3 core files more obvious:
       - drm_stub.c: DRM device allocation/destruction and management
       - drm_fops.c: DRM file_operations (except for ioctl)
       - drm_drv.c: Global DRM init + ioctl handling
      Well, ioctl handling is still spread throughout hundreds of source files,
      but at least the others are clearly defined this way.

      drm: merge device setup into drm_dev_register() · c22f0ace
      David Herrmann authored
      All bus drivers do device setup themselves. This requires us to adjust all
      of them if we introduce new core features. Thus, merge all these into a
      uniform drm_dev_register() helper.
      
      Note that this removes the drm_lastclose() error path for AGP as it is
      horribly broken. Moreover, no bus driver called this in any other error
      path either. Instead, we use the recently introduced AGP cleanup helpers.
      
      We also keep a DRIVER_MODESET condition around pci_set_drvdata() to keep
      semantics.

      drm: add drm_dev_alloc() helper · 1bb72532
      David Herrmann authored
      Instead of managing device allocation+initialization in each bus-driver,
      we should do that in a central place. drm_fill_in_dev() already does most
      of it, but also requires the global drm lock for partial AGP device
      registration.
      
      Split both apart so we have a clean device initialization/allocation
      phase, and a registration phase.

      drm: kill ->gem_init_object() and friends · 16eb5f43
      David Herrmann authored
      All drivers embed gem-objects into their own buffer objects. There is no
      reason to keep drm_gem_object_alloc(), gem->driver_private and
      ->gem_init_object() anymore.
      
      New drivers are highly encouraged to do the same. There is no benefit in
      allocating gem-objects separately.

      drm/nouveau: embed gem object in nouveau_bo · 55fb74ad
      David Herrmann authored
      There is no reason to keep the gem object separately allocated. nouveau is
      the last user of gem_obj->driver_private, so if we embed it, we can get
      rid of 8bytes per gem-object.
      
      The implementation follows the radeon driver. bo->gem is only valid, iff
      the bo was created via the gem helpers _and_ iff the user holds a valid
      gem reference. That is, as the gem object holds a reference to the
      nouveau_bo. If you use nouveau_ref() to gain a bo reference, you are not
      guaranteed to also hold a gem reference. The gem object might get
      destroyed after the last user drops the gem-ref via
      drm_gem_object_unreference(). Use drm_gem_object_reference() to gain a
      gem-reference.
      
      For debugging, we can use bo->gem.filp != NULL to test whether a gem-bo is
      valid. However, this shouldn't be used for real functionality to avoid
      gem-internal dependencies.
      
      Note that the implementation follows the previous style. However, we no
      longer can check for bo->gem != NULL to test for a valid gem object. This
      wasn't done before, so we should be safe now.

      While this code is fixable, the commit itself fails on several levels:
      
       - it should have been a separate helper function
       - why the heck does it do strchr() twice
       - it casts a const char * over into char *
       - sloppy style
       - it's not even a regression fix!
      
      So lets revert it and re-try the patch in v3.13.
