Revert "drm/gem: Rename drm_gem_dumb_map_offset() to drm_gem_map_offset()"

2019-08-07T15:56:48+00:00

This reverts commit 220df83a5394fbf7c1486ba7848794b7b351d598.

Turns out drm_gem_dumb_map_offset really only worked for the dumb buffer
case, so revert the name change.

drm/gem: Rename drm_gem_dumb_map_offset() to drm_gem_map_offset()

2019-06-28T21:01:21+00:00

drm_gem_dumb_map_offset() is a useful helper for non-dumb clients, so
rename it to remove the _dumb and add a comment that it can be used by
shmem clients.

drm/prime: Update docs

2019-06-21T09:48:09+00:00

Yes this is a bit a big patch, but since it's essentially a complete
rewrite of all the prime docs I didn't see how to better split it up.

Changes:
- Consistently point to drm_gem_object_funcs as the preferred hooks,
  where applicable.

- Document all the hooks in &drm_driver that lacked kerneldoc.

- Completely new overview section, which now also includes the cleaned
  up lifetime/reference counting subchapter. I also mentioned the weak
  references in there due to the lookup caches.

- Completely rewritten helper intro section, highlight the
  import/export related functionality.

- Polish for all the functions and more cross references.

I also sprinkled a bunch of todos all over.

Most important: 0 code changes in here. The cleanup motivated by
reading and improving all this will follow later on.

v2: Actually update the prime helper docs. Plus add a few FIXMEs that
I won't address right away in subsequent cleanup patches.

v3:
- Split out the function moving. This patch is now exclusively
  documentation changes.
- Typos and nits (Sam).

v4: Polish suggestions from Noralf.

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: 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.
