Subject: [PATCH v2 0/3] drm/panfrost: drm_gem_map_offset() helper
Date: Thu, 16 May 2019 15:14:44 +0100
Message-ID: <20190516141447.46839-1-steven.price@arm.com> (raw)

Panfrost has a re-implementation of drm_gem_dumb_map_offset() with an
extra bug regarding the handling of imported buffers. However we don't
really want Panfrost calling _dumb functions because it's not a KMS
driver.

This series renames drm_gem_dumb_map_offset() to drop the '_dumb' and
introduces a shmem helper to wrap it. This means that the shmem
implementation can be kept in sync with the semantics the
drm_gem_shmem_mmap() callback provides.

v1: https://lore.kernel.org/lkml/20190513143244.16478-1-steven.price@arm.com/
Changes since v1:
 * Rename drm_gem_dumb_map_offset to drop _dumb
 * Add a shmem helper

Steven Price (3):
  drm/gem: Rename drm_gem_dumb_map_offset() to drm_gem_map_offset()
  drm: shmem: Add drm_gem_shmem_map_offset() wrapper
  drm/panfrost: Use drm_gem_shmem_map_offset()
