[PATCH 00/16] drm/atomic: Remove deprecated atomic iterator macros.

[PATCH 00/16] drm/atomic: Remove deprecated atomic iterator macros.

[Maarten Lankhorst]

It's time to kill off for_each_obj_in_state, and convert
the remainder to for_each_(old/new/both)_obj_in_state.

Maarten Lankhorst (16):
  drm/simple-kms-helper: Fix the check for the mismatch between plane
    and CRTC enabled.
  drm/atomic: Use the correct iterator macro in atomic_remove_fb
  drm/atomic: Use the new helpers in drm_atomic_helper_disable_all()
  drm/atomic: Use new iterator macros in
    drm_atomic_helper_wait_for_flip_done
  drm/vmwgfx: Make check_modeset() use the new atomic iterator macros.
  drm/i915: Use correct iterator macro
  drm/rcar-du: Use new iterator macros
  drm/atmel-hlcdec: Use for_each_new_connector_in_state
  drm/rockchip: Use for_each_oldnew_plane_in_state in
    vop_crtc_atomic_flush
  drm/omapdrm: Fix omap_atomic_wait_for_completion
  drm/mali: Use new atomic iterator macros
  drm/imx: Use atomic iterator macros
  drm/mediatek: Convert to new iterator macros
  drm/msm: Convert to use new iterator macros
  drm/nouveau: Convert nouveau to use new iterator macros
  drm/atomic: Remove deprecated accessor macros

[PATCH 01/16] drm/simple-kms-helper: Fix the check for the mismatch between plane and CRTC enabled.

[Maarten Lankhorst]

You can enable the CRTC and without adding the plane to the state and
it will succeed. This should be prevented in the crtc check instead of
the plane check, because the plane check may never run for atomic
enable, but the crtc check always will.

This is based on a similar check in vmwgfx.

I don't think the checking of resources in this function is very
atomic-like, but it should definitely not use a macro that's about
to be removed.

[PATCH 15/16] drm/nouveau: Convert nouveau to use new iterator macros

[Maarten Lankhorst]

Use the new atomic iterator macros, the old ones are about to be
removed. With the new macros, it's more easy to get old and new state so
get them from the macros instead of from obj->state.

[PATCH 16/16] drm/atomic: Remove deprecated accessor macros

[Maarten Lankhorst]

Now that the last users have been converted, we can finally get rid of
for_each_obj_in_state, we have better macros to replace them with.

Somehow this missed to cc: Noralf ... I guess get_maintainers is not quite

Hm, should we do an s/crtc_state/unused/ here, this is a bit confusing
since we don't really care about whether we get the new or old state.

s/crtc->state->state/state/ ... somehow didn't spot that. And maybe split
this hunk here out and Cc: Gustavo.

Thinking about this some more, this doesn't do anything at all, because
crtc->state->state is always NULL once committed. I think this needs an
entirely different patch, we probably need to check for
crtc_commit->hw_done. This here doesn't do the right thing I think.

Anyway, on the first hunk only, with the bikeshed to rename the unused
variable to "unused" applied:

Afaics vmw_kms_atomic_check_modeset should be static. Feel free to include

I think you missed a few cases of replacing plane_state here. Does this
compile?

Looks correct, but I think Laurent has a patch to rework/remove this.
Found something below anyway.

The code herein looks like the perfect thing to stuff into
encoder->atomic_check, since that can fill out the crtc state too. But
this works too.

Patch itself looks good.

This entire machinery here seems to be the perfect candidate for Boris'
wait_for_flip_done work.

Hi Maarten,

Acked-by: Liviu Dudau <liviu.dudau@arm.com>

Are you going to take the whole series through drm-misc or you want me
to pull this patch into mali-dp tree?

Best regards,
Liviu

I think a variant of drm_atomic_set_fence_for_plane, which takes a
reservation obj (or a dma-buf and then derefs dma_buf->resv itself) would
be nice, so that drivers don't have to hand-roll sub-par fence waiting
code like this (it's e.g. not interruptible for blocking commits).

Anyway, patch itself looks good.

Pretty sure this fails to compile, you've forgotten to do one more
s/plane_state/new_plane_state/.

With that fixed:

Lgtm, but please make sure you do compile test with all three drm-misc
defconfigs. Two of the patches looked like they didn't see a compiler, so

I fear not..

Have a working patch below. :)

----8<------
for_each_obj_in_state is about to be removed, so use the correct new
iterator macros.

Also look at new_plane_state instead of plane->state when looking up
the hw planes in use. They should be the same except when reallocating,
(in which case this code is skipped) and we should really stop looking
at obj->state whenever possible.

Changes since v1:
- Actually compile correctly.

--->8---
for_each_obj_in_state is about to be removed, so convert
to the new iterator macros.

Just like in omap, use crtc_state->active instead of
crtc_state->enable when waiting for completion.

Changes since v1:
- Fix compilation.

Tested with all 3 configs, seems to compile now. :)

I think you have a mixup here of the crtc states for old and new crtc,
both are get_new_crtc_state.

Otherwise lgtm.

Thanks.

Pushed patch 1-3, 4 (first hunk only), 5 (with static fix), 6, 8, 9, 11-13.

Still hoping for ack from driver maintainers on patch 7 (v2), 10, 14 (v2) and 15 (with the fix daniel spotted).
