[00/15] drm: Do not use import_attach in drivers

Message

Thomas Zimmermann March 17, 2025, 1:06 p.m. UTC

Avoid struct drm_gem_object.import_attach in many DRM drivers that
use it to get the object's dma-buf or test for an imported buffer.

The helper drm_gem_is_imported() tests if a GEM object's buffer
has been imported into the driver. The corresponding dma-buf is
referenced by the object itself. Both cases avoid import_attach.

The import_attach field in struct drm_gem_object is an artifact of
the import process, but should not be used otherwise. This series
fixes most of the drivers in the DRM misc tree. Other DRM drivers
can be converted when drm_gem_is_imported() becomes available in
their tree.

Thomas Zimmermann (15):
  drm/armada: Test for imported buffers with drm_gem_is_imported()
  drm/etnaviv: Test for imported buffers with drm_gem_is_imported()
  drm/etnaviv: Use dma_buf from GEM object instance
  drm/exynos: Test for imported buffers with drm_gem_is_imported()
  drm/gud: Test for imported buffers with drm_gem_is_imported()
  drm/msm: Test for imported buffers with drm_gem_is_imported()
  drm/omapdrm: Test for imported buffers with drm_gem_is_imported()
  drm/panfrost: Test for imported buffers with drm_gem_is_imported()
  drm/panthor: Test for imported buffers with drm_gem_is_imported()
  drm/rockchip: Test for imported buffers with drm_gem_is_imported()
  drm/vc4: Test for imported buffers with drm_gem_is_imported()
  drm/virtio: Test for imported buffers with drm_gem_is_imported()
  drm/vmwgfx: Test for imported buffers with drm_gem_is_imported()
  drm/vmwgfx: Use dma_buf from GEM object instance
  drm/xen: Test for imported buffers with drm_gem_is_imported()
