      drm/msm: fix double struct_mutex acquire · b544021f
      Rob Clark authored
      Mutex is already grabbed in show_locked().. somehow this slipped
      through.

      Merge tag 'drm-intel-next-2014-07-25-merged' of git://anongit.freedesktop.org/drm-intel into drm-next
      
      Final feature pull for 3.17.
      
      drm-intel-next-2014-07-25:
      - Ditch UMS support (well just the config option for now)
      - Prep work for future platforms (Sonika Jindal, Damien)
      - runtime pm/soix fixes (Paulo, Jesse)
      - psr tracking improvements, locking fixes, now enabled by default!
      - rps fixes for chv (Deepak, Ville)
      - drm core patches for rotation support (Ville, Sagar Kamble) - the i915 parts
        unfortunately didn't make it yet
      - userptr fixes (Chris)
      - minimum backlight brightness (Jani), acked long ago by Matthew Garret on irc -
        I've forgotten about this patch :(
      
      QA is a bit unhappy about the DP MST stuff since it broke hpd testing a
      bit, but otherwise looks sane. I've backmerged drm-next to resolve
      conflicts with the mst stuff, which means the new tag itself doesn't
      contain the overview as usual.

      drm: close race in connector registration (v2) · 2ee39452
      Dave Airlie authored
      Daniel pointed out with hotplug that userspace could be trying to oops us
      as root for lols, and that to be correct we shouldn't register the object
      with the idr before we have fully set the connector object up.
      
      His proposed solution was a lot more life changing, this seemed like a simpler
      proposition to me, get the connector object id from the idr, but don't
      register the object until the drm_connector_register callback.
      
      The open question is whether the drm_mode_object_register needs a bigger lock
      than just the idr one, but I can't see why it would, but I can be locking
      challenged.
      
      v2: fix bool noreg into sane - add comment.

      drm/i915: only hook up hpd pulse for DP outputs · f68d697e
      Chris Wilson authored
      On HSW+, the digital encoders are shared between HDMI and DP outputs,
      with one encoder masquerading as both. The VBT should tell us if we need
      to have DP or HDMI support on a particular port, but if we don't have DP
      support and we enable the DP hpd pulse handler then we cause an oops.
      
      Don't hook up the DP hpd handling if we don't have a DP port.

      Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next
      
         This pull request includes i80 interface support, module auto-loading
         ipp consolidation, and trivail fixups and cleanups.
      
      Summary:
      - Add i80 interface support. For this, we added some features to
        Exynos drm framework, which don't affect any other SoC and common
        framework because they are specific to Exynos drm.
      - Add module auto-loading support. For this, sub drivers of Exynos drm
        exports their of match tables to userspace. This allows modules to be
        loaded automatically based on devicetree information
      - Consolidate ipp driver. This patch just just includes cleanups and
        a littl bit refactoring codes.
      
      If there is any problem, please kindly let me know.

      drm/exynos: g2d: let exynos_g2d_get_ver_ioctl fail · ef7ce055
      Tobias Jakobi authored
      Currently the DRM_IOCTL_EXYNOS_G2D_GET_VER ioctl always succeeds, even
      if no G2D support is available. Let the ioctl fail when this is the
      case, so that userspace can accurately probe for G2D support.
      
      This also fixes the exynos tests in libdrm. There 'g2d_init' doesn't
      fail when G2D is absent, leading to a segfault later.

      drm/exynos: g2d: make ioctls more robust · 1cd1ea56
      Tobias Jakobi authored
      Both exynos_g2d_set_cmdlist_ioctl and exynos_g2d_exec_ioctl don't check
      if the G2D was succesfully probe. If that is not the case, then g2d_priv
      is just NULL and extracting 'dev' from it in the next step  is going to
      produce a kernel oops.
      
      Add proper checks and return ENODEV if the G2D is not available.

      This reverts commit d0896218 was
      original to prevent multiple MODULE_DEVICE_TABLE in one module.
      Which, as a side-effect broke autoloading of the module.
      
      Since 21bdd17b it is possible to have
      multiple calls to MODULE_DEVICE_TABLE, so the patch can be
      reverted to restore support for autoloading
