Fifth iteration. Instead of trying to convert all drivers straight away,
implement all macros that are required to get state working.
Old situation:
Use obj->state, which can refer to old or new state.
Use drm_atomic_get_(existing_)obj_state, which can refer to new or old state.
Use for_each_obj_in_state, which refers to new or old state.
New situation:
During atomic check:
- Use drm_atomic_get_obj_state to add a object to the atomic state,
or get the new state.
- Use drm_atomic_get_(old/new)_obj_state to peek at the new/old state,
without adding the object. This will return NULL if the object is
not part of the state. For planes and connectors the relevant crtc_state
is added, so this will work to get the crtc_state from obj_state->crtc
too, this means not having to write some error handling.
During atomic commit:
- Do not use drm_atomic_get_obj_state, obj->state or drm_atomic_get_(existing_)obj_state
any more, replace with drm_atomic_get_old/new_obj_state calls as required.
During both:
- Use for_each_(new,old,oldnew)_obj_in_state to get the old or new state as needed.
oldnew will be renamed to for_each_obj_in_state after all callers are converted
to the new api.
When not doing atomic updates:
Look at obj->state for now. I have some patches to fix this but I was asked to
make it return a const state. This breaks a lot of users though so I skipped that
patch in this iteration.
This series will return the correct state regardless of swapping.
Maarten Lankhorst (5):
drm/atomic: Fix atomic helpers to use the new iterator macros, v2.
drm/atomic: Make drm_atomic_plane_disabling easier to understand.
drm/atomic: Add macros to access existing old/new state, v2.
drm/atomic: Convert get_existing_state callers to get_old/new_state,
v3.
drm/blend: Use new atomic iterator macros.

There are new iterator macros that annotate whether the new or old
state should be used. This is better than using a state that depends on
whether it's called before or after swap. For clarity, also rename the
variables from $obj_state to (old,new)_$obj_state as well.
Changes since v1:
- Use old/new_*_state for variable names as much as possible. (pinchartl)
- Expand commit message.

This function becomes a lot simpler when having passed both the old and
new state to it. Looking at all callers, it seems that old_plane_state
is never NULL so the check can be dropped.

After atomic commit, these macros should be used in place of
get_existing_state. Also after commit get_xx_state should no longer
be used because it may not have the required locks.
The calls to drm_atomic_get_existing_$obj_state should no longer be
used, and converted over to these new calls.
Changes since v1:
- Expand commit message.
- Deprecate get_existing_*_state functions in the documentation.

This is a straightforward conversion that converts all the users of
get_existing_state in atomic core to use get_old_state or get_new_state
Changes since v1:
- Fix using the wrong state in drm_atomic_helper_update_legacy_modeset_state.
Changes since v2:
- Use the correct state in disable_outputs()

There are new iterator macros that annotate whether the new or old
state should be used. This is better than using a state that depends on
whether it's called before or after swap. For clarity, also rename the
variables from $obj_state to (old,new)_$obj_state as well.

I believe more *_state -> *_(new|old)_state renames could be useful, but that
can be addressed as a subsequent patch, so

Yeah I noticed, patch 1 and 5 are affected, will resend those.

There are new iterator macros that annotate whether the new or old
state should be used. This is better than using a state that depends on
whether it's called before or after swap. For clarity, also rename the
variables from $obj_state to (old,new)_$obj_state as well.
Changes since v1:
- Use old/new_*_state for variable names as much as possible. (pinchartl)
- Expand commit message.
Changes since v2:
- Rebase on top of link training patches.
- free -> cleanup (pinchartl)

* [PATCH v4.1 4/5] drm/atomic: Convert get_existing_state callers to get_old/new_state, v4.
2017-03-01 1:04 ` Laurent Pinchart
@ 2017-03-01 9:22 ` Maarten Lankhorst
0 siblings, 0 replies; 16+ messages in thread
From: Maarten Lankhorst @ 2017-03-01 9:22 UTC (permalink / raw)
To: Laurent Pinchart, dri-devel; +Cc: intel-gfx
This is a straightforward conversion that converts all the users of
get_existing_state in atomic core to use get_old_state or get_new_state
Changes since v1:
- Fix using the wrong state in drm_atomic_helper_update_legacy_modeset_state.
Changes since v2:
- Use the correct state in disable_outputs()
Changes since v3:
- Rebase for link status training.
