drm/repaper: Use framebuffer dma-buf helpers

2021-07-23T18:18:11+00:00

Replace dma_buf_begin_cpu_access() with drm_gem_fb_begin_cpu_access();
same for _end_cpu_access(). Remove some boiler-plate code. No functional
changes.

drm/tiny: drm_gem_simple_display_pipe_prepare_fb is the default

2021-06-24T13:40:11+00:00

Goes through all the drivers and deletes the default hook since it's
the default now.

drm/gem: Move drm_gem_fb_prepare_fb() to GEM atomic helpers

2021-02-23T07:54:22+00:00

The function drm_gem_fb_prepare_fb() is a helper for atomic modesetting,
but currently located next to framebuffer helpers. Move it to GEM atomic
helpers, rename it slightly and adopt the drivers. Same for the rsp
simple-pipe helper.

Compile-tested with x86-64, aarch64 and arm. The patch is fairly large,
but there are no functional changes.

v3:
	* remove out-comented line in drm_gem_framebuffer_helper.h
	  (Maxime)
v2:
	* rename to drm_gem_plane_helper_prepare_fb() (Daniel)
	* add tutorial-style documentation

drm/: Constify struct drm_driver

2020-11-06T09:31:26+00:00

Only the following drivers aren't converted:
- amdgpu, because of the driver_feature mangling due to virt support.
  Subsequent patch will address this.
- nouveau, because DRIVER_ATOMIC uapi is still not the default on the
  platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is
  maybe a bit too much, hence the num_ioctls assignment prevents a
  const driver structure.
- arcpgu, because that is stuck behind a pending tiny-fication series
  from me.
- legacy drivers, because legacy requires non-const drm_driver.

Note that for armada I also went ahead and made the ioctl array const.

Only cc'ing the driver people who've not been converted (everyone else
is way too much).

v2: Fix one misplaced const static, should be static const (0day)

v3:
- Improve commit message (Sam)

drm/tiny/repaper: Drop edp->enabled

2020-06-24T07:17:30+00:00

Same patch as the mipi-dbi one, atomic tracks this for us already, we
just have to check the right thing.

drm/cma-helper: Rework DRM_GEM_CMA_VMAP_DRIVER_OPS macro

2020-06-10T07:01:41+00:00

Rename the macro to DRM_GEM_CMA_DRIVER_OPS_VMAP to align naming with
SHMEM helpers and drm_gem_cma_prime_import_sg_table_vmap(). An variant of
the macro is provided for drivers that override the default .dumb_create
callback. Adapt drivers to the changes.

v3:
	* rename macro to signal implicit vmap on imported buffers
v2:
	* provide DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE

drm/repaper: Drop explicit drm_mode_config_cleanup call

2020-03-26T15:08:57+00:00

Allows us to drop the drm_driver.release callback.

This is made possible by a preceeding patch which added a drmm_
cleanup action to drm_mode_config_init(), hence all we need to do to
ensure that drm_mode_config_cleanup() is run on final drm_device
cleanup is check the new error code for _init().

v2: Explain why this cleanup is possible (Laurent).

v3: Use drmm_mode_config_init() for more clarity (Sam, Thomas)
I also noticed that I've failed to add the error checking,
__must_check caught that.
