[PATCH v3 00/43] Convert most CMA-based drivers to GEM object functions

[PATCH v3 00/43] Convert most CMA-based drivers to GEM object functions

[Thomas Zimmermann]

Most of the CMA-based drivers use the default implementation for the
callbacks in struct drm_driver. With this patch, these interfaces are
initialized with a common helper macro and GEM object functions replace
several deprecated interfaces.

To address Laurent's comment on the amount of changes per patch, I re-
organized the series.

 1) There are now DRIVER_OPS macros for drivers that require a virtual
    address on imported buffers, and macros for drivers that don't. Therefore,
    drivers don't switch to drm_gem_cma_prime_import_sg_table_vmap()
    implicitly when they begin using the DRIVER_OPS macro.

 2) I split each driver's patch into two: the first converts the driver to
    GEM CMA object functions, the second introduces the DRIVER_OPS macro.
    Neither patch should result in a functional change. I kept existing R-b
    and A-b tags on both patches. Existing Tested-by tags are only on the
    final patch, as that's closest to what has been tested.

 3) I dropped the conversion to drm_gem_prime_mmap() from the patchset. As
    part of this change, the CMA object functions could provide an mmap
    function, which is worth it's own series. The patch for aspeed requires
    drm_gem_prime_mmap(), so I removed it from the series.

Patches 1 to 3 update the existing macro and helper to similar naming as with
SHMEM, add a new DRIVER_OPS macro, and add helpers for drivers that override
the default implementation for .dumb_create(). The remaining patches up to
the final one convert the drivers. The kirin driver also changes to the
default dumb_create function. The final patch deletes .gem_print_info from
struct drm_driver.

I don't have much of the hardware, so it's only compile-tested on aarch64,
arm and x86-64 only. Several patches have Tested-by tags.

v3:
	* reorganized the series
	* split each driver patch into two small ones (Laurent)
	* drop the conversion to drm_gem_prime_mmap()
	* remove the patch for aspeed
v2:
  	* add more detailed commit messages (Laurent, Sam)
	* use default .dumb_create implementation in kirin (Emil)
	* fix zte build error (Sam, Emil)
	* introduce DRM_GEM_CMA_DRIVER_OPS_WITH_DUMB_CREATE (everyone)

[PATCH v3 02/43] drm/cma-helper: Rework DRM_GEM_CMA_VMAP_DRIVER_OPS macro

[Thomas Zimmermann]

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

[PATCH v3 03/43] drm/cma-helper: Add DRM_GEM_CMA_DRIVER_OPS to set default GEM CMA functions

[Thomas Zimmermann]

The macro to DRM_GEM_CMA_DRIVER_OPS sets GEM callbacks in struct drm_driver
to their defaults for CMA. An variant of the macro is provided for drivers
that override the default .dumb_create callback. Adapt drivers to the changes.

Create GEM objects with drm_gem_cma_create_object_default_funcs(), which
allocates the object and sets CMA's default object functions. Corresponding
callbacks in struct drm_driver are cleared. No functional changes are made.

Driver and object-function instances use the same callback functions, with
the exception of vunmap. The implementation of vunmap is empty and left out
in CMA's default object functions.

[PATCH v3 12/43] drm/hisilicon/kirin: Set .dumb_create to drm_gem_cma_dumb_create()

[Thomas Zimmermann]

The kirin drivers uses drm_gem_cma_dumb_create_internal() for its
.dumb_create implementation. The function is meant for internal use
only by drivers that require additional buffer setup.

Kirin does not do an additional setup, so convert it over to
drm_gem_cma_dumb_create().

[PATCH v3 23/43] drm/mcde: Use GEM CMA object functions

[Thomas Zimmermann]

Create GEM objects with drm_gem_cma_create_object_default_funcs(), which
allocates the object and sets CMA's default object functions. Corresponding
callbacks in struct drm_driver are cleared. No functional changes are made.

Driver and object-function instances use the same callback functions, with
the exception of vunmap. The implementation of vunmap is empty and left out
in CMA's default object functions.

[PATCH v3 33/43] drm/stm: Use GEM CMA object functions

[Thomas Zimmermann]

Create GEM objects with drm_gem_cma_create_object_default_funcs(), which
allocates the object and sets CMA's default object functions. Corresponding
callbacks in struct drm_driver are cleared. No functional changes are made.

Driver and object-function instances use the same callback functions, with
the exception of vunmap. The implementation of vunmap is empty and left out
in CMA's default object functions.

v3:
	* convert to DRIVER_OPS macro in a separate patch

I like code removal :-) Looking forward to the removal of more
GEM-related fields from struct drm_driver.

Re: [PATCH v3 01/43] drm/cma-helper: Rename symbols from drm_cma_gem_ to drm_gem_cma_

Hi Thomas,

Thank you for the patch.

Thank you for the patch.

Speaking of naming, I wish we could rename drm_gem_cma_* to something
else, as those helpers don't use CMA directly (and may not use it at
all), but I think that would be too much intrusive changes for too
little gain :-(

I agree. Calling them GEM DMA helpers would be more precise. But I don't
really see an easy solution without either a big patch that touches
everything, or a lot of small patches with ugly intermediate states.

IMHO the best option would probably be an additional header file
drm_gem_dma_helper.h that defines a dma name for each cma name. Drivers
could then be converted individually with a single per-driver patch.

Best regards
Thomas

From todo.rst:

"
Rename CMA helpers to DMA helpers
---------------------------------

CMA (standing for contiguous memory allocator) is really a bit an accident of
what these were used for first, a much better name would be DMA helpers. In the
text these should even be called coherent DMA memory helpers (so maybe CDM, but
no one knows what that means) since underneath they just use dma_alloc_coherent.

Contact: Laurent Pinchart, Daniel Vetter

Level: Intermediate (mostly because it is a huge tasks without good partial
milestones, not technically itself that challenging)
"

The same?

Yes, I've been thinking of this. That would be a good task for someone
to get familiar with the DRM code.
