drm/atomic: Extract needs_modeset function

2015-06-19T15:25:01+00:00

We use the same check already in the atomic core, so might as well
make this official. And it's also reused in e.g. i915.

Motivated by Maarten's idea to extract a connector_changed state out
of mode_changed.

drm/atomic: Add MODE_ID property

2015-05-26T13:50:42+00:00

Atomic modesetting: now with modesetting support.

v2: Moved drm_atomic_set_mode_prop_for_crtc from previous patch; removed
    state->active fiddling, documented return code. Changed property
    type to DRM_MODE_PROP_BLOB.

drm/atomic: Add current-mode blob to CRTC state

2015-05-26T13:50:38+00:00

Add a blob property tracking the current mode to the CRTC state, and
ensure it is properly updated and referenced.

v2: Continue using crtc_state->mode inside getcrtc, instead of reading
    out the mode blob. Use IS_ERR and PTR_ERR from create_blob. Move
    set_mode_prop_for_crtc to later patch where it actually gets used.
    Enforce !!state->enable == !!state->mode_blob inside
    drm_atomic_crtc_check.

drm: Add drm_atomic_set_mode_for_crtc

2015-05-26T13:50:34+00:00

Add a new helper, to be used later for blob property management, that
sets the mode for a CRTC state, as well as updating the CRTC enable/active
state at the same time.

v2: Do not touch active/mode_changed in CRTC state. Document return
    value. Remove stray drm_atomic_set_mode_prop_for_crtc declaration.

v3: Remove i915 changes, and leave it directly bashing crtc_state->mode
    for the meantime.

drm/atomic: add drm_atomic_add_affected_planes

2015-05-21T08:29:07+00:00

This is a convenience function to add all planes for a crtc,
similar to add_affected_connectors. This will be used in
drm_atomic_helper_check_modeset, but drivers can call it too
when they need to recalculate all state.

drm/atomic: Allow drivers to subclass drm_atomic_state, v3

2015-05-18T14:39:41+00:00

Drivers may need to store the state of shared resources, such as PLLs
or FIFO space, into the atomic state. Allow this by making it possible
to subclass drm_atomic_state.

Changes since v1:
- Change member names for functions to atomic_state_(alloc,clear)
- Change __drm_atomic_state_new to drm_atomic_state_init
- Allow free function to be overridden too, in case extra memory is
  allocated in alloc.
Changes since v2:
- Rename *_default_free to default_release, to make clear it doesn't
  free the state object itself.

drm/atomic: add drm_atomic_get_existing_*_state helpers

2015-05-13T09:28:22+00:00

There are cases where we want to test if a given object is
part of the state, but don't want to add them if they're not.

drm/atomic: Add for_each_{connector,crtc,plane}_in_state helper macros

2015-04-11T16:50:22+00:00

This saves some typing whenever a iteration over all the connector,
crtc or plane states in the atomic state is written, which happens
quite often.

drm/atomic: Don't try to free a NULL state

Consistently with other free functions, handle the NULL case without
oopsing.
