X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2cca45574007b4a77fa5f63ea45d664510cec22a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Merge tag 'topic/drm-misc-2016-06-07' of git://anongit.freedesktop.org/drm-intel into drm-next

As promised, piles of prep work all around:
- drm_atomic_state rework, prep for nonblocking commit helpers
- fence patches from Gustavo and Christian to prep for atomic fences and
  some cool work in ttm/amdgpu from Christian
- drm event prep for both nonblocking commit and atomic fences
- Gustavo seems on a crusade against the non-kms-native version of the
  vblank functions.
- prep work from Boris to nuke all the silly ->best_encoder
  implementations we have (we really only need that for truly dynamic
  cases like dvi-i vs dvi-d or dp mst selecting the right transcoder on
  intel)
- prep work from Laurent to rework the format handling functions
- and few small things all over

 +       <para>
 +         The dma-buf subsystem provides the framework for sharing buffers
 +         for hardware (DMA) access across multiple device drivers and
 +         subsystems, and for synchronizing asynchronous hardware access.
 +       </para>
 +       <para>
 +         This is used, for example, by drm "prime" multi-GPU support, but
 +         is of course not limited to GPU use cases.
 +       </para>
 +       <para>
 +         The three main components of this are: (1) dma-buf, representing
 +         a sg_table and exposed to userspace as a file descriptor to allow
 +         passing between devices, (2) fence, which provides a mechanism
 +         to signal when one device as finished access, and (3) reservation,
 +         which manages the shared or exclusive fence(s) associated with
 +         the buffer.
