They're purely for internal use, not for drivers.

drm: drop use of drmP.h in drm/*

2019-05-27T16:07:03+00:00

The use of the drmP.h header file is deprecated.
Remove use from all files in drm/*
so people do not look there and follow a bad example.

Build tested allyesconfig,allmodconfig on x86, arm etc.
Including alpha that is as always more challenging than
the rest.

drm/gem: Fix sphinx warnings

2019-04-25T14:02:10+00:00

Sphinx really wants colons after arguments :/

drm: Add helpers for setting up an array of dma_fence dependencies.

2019-04-16T22:32:20+00:00

I needed to add implicit dependency support for v3d, and Rob Herring
has been working on it for panfrost, and I had recently looked at the
lima implementation so I think this will be a good intersection of
what we all want and simplify our scheduler implementations.

v2: Rebase on xa_limit_32b API change, and tiny checkpatch cleanups on
    the way in (unsigned int vs unsigned, extra return before
    EXPORT_SYMBOL_GPL)

drm: Add a drm_gem_objects_lookup helper

2019-04-12T17:53:58+00:00

Similar to the single handle drm_gem_object_lookup(),
drm_gem_objects_lookup() takes an array of handles and returns an array
of GEM objects.

v2:
- Take the userspace pointer directly and allocate the array.
- Expand the function documentation.

drm: Use the same mmap-range offset and size for GEM and TTM

2019-03-19T20:03:53+00:00

GEM defines DRM_FILE_PAGE_OFFSET_{START,SIZE} constants for the
mmap-able range of addresses. TTM can use them as well.

drm: Add helpers for locking an array of BO reservations.

2019-03-14T16:22:57+00:00

Now that we have the reservation object in the GEM object, it's easy
to provide a helper for this common case.  Noticed while reviewing
panfrost and lima drivers.  This particular version came out of v3d,
which in turn was a copy from vc4.

v2: Fix kerneldoc warnings.

drm: Add reservation_object to drm_gem_object

2019-02-19T10:08:40+00:00

Many users of drm_gem_object embed a struct reservation_object into
their subclassed struct, so let's add one to struct drm_gem_object.
This will allow removing the reservation object from the subclasses
and removing the ->gem_prime_res_obj callback.

With the addition, add a drm_gem_reservation_object_wait() helper
function for drivers to use in wait ioctls.

drm: Trivial comment grammar cleanups

2019-02-04T09:21:17+00:00

Most of these are just cases where code comments used contractions
(it's, who's) where they actually mean to use a possessive pronoun (its,
whose) or vice-versa.
