      udl: bind the framebuffer to the correct device. · 33896bf3
      Dave Airlie authored
      This just moves the fb sysfs node beside the drm sysfs node which
      I fixed before.
      
      just noticed it in passing.

      drm: prime: fix refcounting on the dmabuf import error path · 011c2282
      Imre Deak authored
      In commit be8a42ae we inroduced a refcount problem, where on the
      drm_gem_prime_fd_to_handle() error path we'll call dma_buf_put() for
      self imported dma buffers.
      
      Fix this by taking a reference on the dma buffer in the .gem_import
      hook instead of assuming the caller had taken one. Besides fixing the
      bug this is also more logical.

      drm/prime: keep a reference from the handle to exported dma-buf (v6) · 219b4733
      Dave Airlie authored
      Currently we have a problem with this:
      1. i915: create gem object
      2. i915: export gem object to prime
      3. radeon: import gem object
      4. close prime fd
      5. radeon: unref object
      6. i915: unref object
      
      i915 has an imported object reference in its file priv, that isn't
      cleaned up properly until fd close. The reference gets added at step 2,
      but at step 6 we don't have enough info to clean it up.
      
      The solution is to take a reference on the dma-buf when we export it,
      and drop the reference when the gem handle goes away.
      
      So when we export a dma_buf from a gem object, we keep track of it
      with the handle, we take a reference to the dma_buf. When we close
      the handle (i.e. userspace is finished with the buffer), we drop
      the reference to the dma_buf, and it gets collected.
      
      This patch isn't meant to fix any other problem or bikesheds, and it doesn't
      fix any races with other scenarios.
      
      v1.1: move export symbol line back up.
      
      v2: okay I had to do a bit more, as the first patch showed a leak
      on one of my tests, that I found using the dma-buf debugfs support,
      the problem case is exporting a buffer twice with the same handle,
      we'd add another export handle for it unnecessarily, however
      we now fail if we try to export the same object with a different gem handle,
      however I'm not sure if that is a case I want to support, and I've
      gotten the code to WARN_ON if we hit something like that.
      
      v2.1: rebase this patch, write better commit msg.
      v3: cleanup error handling, track import vs export in linked list,
      these two patches were separate previously, but seem to work better
      like this.
      v4: danvet is correct, this code is no longer useful, since the buffer
      better exist, so remove it.
      v5: always take a reference to the dma buf object, import or export.
      (Imre Deak contributed this originally)
      v6: square the circle, remove import vs export tracking now
      that there is no difference

      drm: Kill user_modes list and the associated ioctls · c55b6b3d
      Ville Syrjälä authored
      There is no way to use modes added to the user_modes list. We never
      look at the contents of said list in the kernel, and the only operations
      userspace can do are attach and detach. So the only "benefit" of this
      interface is wasting kernel memory.
      
      Fortunately it seems no real user space application ever used these
      ioctls. So just kill them.
      
      Also remove the prototypes for the non-existing drm_mode_addmode_ioctl()
      and drm_mode_rmmode_ioctl() functions.
      
      v2: Use drm_noop instead of completely removing the ioctls

      drm/i915: correct the calculation of first_pd_entry_in_global_pt · 43b27290
      Zhang, Xiong Y authored
      When ppgtt is enabled, dev_priv->gtt.total has excluded the gtt space
      occupied by ppgtt table in i915_gem_init_global_gtt() function. So the
      calculation of first_pd_entry_in_global_pt doesn't need to subtract
      I915_PPGTT_PD_ENTRIES again. Or else PPGTT directory table will be
      destroyed by global gtt allocation.
      
      This regression has been introduced in

          drm/i915: remove intel_gtt structure
      
      The breakage is pretty subtile since the old gtt_total_entries
      included the pde range, whereas the new on did not.
