drm/atomic: add a drm_atomic_clean_old_fb helper.

2015-11-17T11:02:14Z

This is useful for all the boilerplate code about cleaning old_fb. Signed-off-by: Maarten Lankhorst Reviewed-by: Daniel Vetter Signed-off-by: Jani Nikula Link: http://patchwork.freedesktop.org/patch/msgid/1447237751-9663-4-git-send-email-maarten.lankhorst@ubuntu.com

drm/atomic: add connectors_changed to separate it from mode_changed, v2

2015-07-27T08:06:38Z

This can be a separate case from mode_changed, when connectors stay the same but only the mode is different. Drivers may choose to implement specific optimizations to prevent a full modeset for this case. Changes since v1: - Update kerneldocs slightly.

drm/atomic: Extract needs_modeset function

2015-06-19T15:25:01Z

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. Cc: Maarten Lankhorst Reviewed-By: Maarten Lankhorst Signed-off-by: Daniel Vetter

drm/atomic: fix out of bounds read in for_each_*_in_state helpers

2015-05-26T15:31:52Z

for_each_*_in_state validate array index after access to array elements, thus perform out of bounds read. Fix this by validating index in the first place and read array element iff validation was successful.

drm/atomic: Add MODE_ID property

2015-05-26T13:50:42Z

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. Signed-off-by: Daniel Stone Tested-by: Sean Paul Signed-off-by: Daniel Vetter

drm: Add drm_atomic_set_mode_for_crtc

2015-05-26T13:50:34Z

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

2015-05-21T08:29:07Z

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

2015-05-18T14:39:41Z

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

2015-05-13T09:28:22Z

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. Signed-off-by: Maarten Lankhorst Signed-off-by: Daniel Vetter

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

2015-04-11T16:50:22Z

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. Cc: dri-devel@lists.freedesktop.org Signed-off-by: Ander Conselvan de Oliveira Signed-off-by: Daniel Vetter
