[PATCH v3 00/28] DRM API Conversions

[Cihangir Akturk]

Changes since v2:

- Patch series is based on *drm-misc-next* as suggested by Sean Paul.

- Dropped patch 05 (drm/atmel-hlcdc) and patch 25 (drm/vc4) from v2,
  since they were already pulled in the drm-misc-next

Changes since v1:

- This time patches were generated with coccinelle instead of my own
  script, as suggested by Daniel Vetter.

- Fixed the typo in commit messages. s/adn/and

Note: I've included r-b, a-b tags, as these patches are identical to v1
except for the file: drivers/gpu/drm/i915/i915_gem_object.h

This patch set replaces the occurrences of drm_*_reference() and
drm_*_unreference() with the new drm_*_get() and drm_*_put() functions.
All patches in the series do the same thing, converting to the new APIs.
I created patches per DRM driver as suggested by Daniel Vetter.

This patch set was generated by scripts/coccinelle/api/drm-get-put.cocci

Background:

In the kernel, reference counting APIs use *_get(), *_put() style naming
to reference-count the objects. But DRM subsystem uses a different
naming for them such as *_reference(), *_unreference() which is
inconsistent with the other reference counting APIs in the kernel. To
solve this consistency issue, Thierry Reding introduced a couple of
functions and compatibility aliases in the following commits for them.

[PATCH v3 01/28] drm/amdgpu: switch to drm_*_get(), drm_*_put() helpers

[Cihangir Akturk]

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

[PATCH v3 05/28] drm/bochs: switch to drm_*_get(), drm_*_put() helpers

[Cihangir Akturk]

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

[PATCH v3 10/28] drm/hisilicon: switch to drm_*_get(), drm_*_put() helpers

[Cihangir Akturk]

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

[PATCH v3 15/28] drm/msm: switch to drm_*_get(), drm_*_put() helpers

[Cihangir Akturk]

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be

[PATCH v3 17/28] drm/omapdrm: switch to drm_*_get(), drm_*_put() helpers

[Cihangir Akturk]

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

[PATCH v3 20/28] drm/rockchip: switch to drm_*_get(), drm_*_put() helpers

[Cihangir Akturk]

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

[PATCH v3 26/28] drm/virtio: switch to drm_*_get(), drm_*_put() helpers

[Cihangir Akturk]

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

FWIW, I already picked up v1 of these patches for radeon and amdgpu.

> Background:
> 
> In the kernel, reference counting APIs use *_get(), *_put() style naming
> to reference-count the objects. But DRM subsystem uses a different
> naming for them such as *_reference(), *_unreference() which is
> inconsistent with the other reference counting APIs in the kernel. To
> solve this consistency issue, Thierry Reding introduced a couple of
> functions and compatibility aliases in the following commits for them.

I have already applied v1 of this patch to the etnaviv tree.

Erm vboxvideo is in staging, does this mean all patches for
it will now go through drm-misc-next despite it being in
staging (*) ?  Because if some patches get merged through
drm-misc-next and some through Greg's staging repo that
is not going to end well.

Hans



*) that is fine, the same is done for e.g. the media drivers afaik

Seems this is against a rather old version of drm/i915. Can you pls
regenerate against linux-next or the drm-tip branch from

https://cgit.freedesktop.org/drm-tip

But in general, for large-scale refactoring like this, the recommendation
is to base them on linux-next, since that will have all pending patches
applied for every part of the kernel.

Hi Hans,
Thanks for pointing this out. I picked it up as I was vacuuming up the
rest of the set that was not yet applied, not realizing the staging
implications. It's not my intention to start taking vboxvideo through
-misc.

Hopefully this won't cause any nasty conflicts with Greg's staging
tree, and we can treat it as a one-off. If it does cause problems, I
can revert it in -misc in favor of taking it through staging.

[PATCH] drm/i915: switch to drm_*_get(), drm_*_put() helpers

[Cihangir Akturk]

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.

drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

-staging doesn't work for drm. And yes this patch needs to go in through
drm-misc I think (I don't want to be at Greg's mercy for merging cleanups,
same way we don't wait for driver maintainers if they don't merge the
patch in a timely fashion).

I'd say if no one is actually working on vbox cleanup (i.e. porting to
atomic) we'll throw it out next cycle again.

Michael Thayer from vbox upstream has said repeatedly that he is
preparing a patch-set to move vboxvideo over to the atomic APIs).

ATM I'm focusing on the other 2 vbox-guest drivers (but that is almost
done) so if Michael does not follow through on this then I will take
care of this.

Either way please don't remove the driver, we do plan to clean it up
and having it ping pong into, out of and back into the mainline kernel
is really not helpful.

Regards,

Hans

Mind if I change the subject line to "drm/vc4: Continue the switch to
drm_*_put() helpers"? to distinguish from the patch that already landed?

(Looks like your previous patch was generated before my BO labeling code
landed, so we got another little patch here cleaning up the new code as
well)

It's OK with me. Go ahead, change to whatever you want.

This looks trivial - provided drm-misc has no conflicts, I'm happy for
it to be applied there.  Thanks.
