2016-10-17drm: Add reference counting to drm_atomic_stateChris Wilson1-1/+2
drm_atomic_state has a complicated single owner model that tracks the single reference from allocation through to destruction on another thread - or perhaps on a local error path. We can simplify this tracking by using reference counting (at a cost of a few more atomics). This is even more beneficial when the lifetime of the state becomes more convoluted than being passed to a single worker thread for the commit. v2: Double check !intel atomic_commit functions for missing gets v3: Update kerneldocs Signed-off-by: Chris Wilson <[email protected]> Cc: Daniel Vetter <[email protected]> Cc: [email protected] Reviewed-by: Eric Engestrom <[email protected]> Reviewed-by: Sean Paul <[email protected]> Signed-off-by: Daniel Vetter <[email protected]> Link: http://patchwork.freedesktop.org/patch/msgid/[email protected]
2016-09-22drm: Don't swallow error codes in drm_dev_alloc()Tom Gundersen1-2/+2
There are many reasons other than ENOMEM that drm_dev_init() can fail. Return ERR_PTR rather than NULL to be able to distinguish these in the caller.

2016-08-29drm/atomic-helper: Add NO_DISABLE_AFTER_MODESET flag support for plane commitLiu Ying1-2/+4
Drivers may set the NO_DISABLE_AFTER_MODESET flag in the 'flags' parameter of the helper drm_atomic_helper_commit_planes() if the relevant display controllers(e.g., IPUv3 for imx-drm) require to disable a CRTC's planes when the CRTC is disabled. The helper would skip the ->atomic_disable call for a plane if the CRTC of the old plane state needs a modesetting operation. Of course, the drivers need to disable the planes in their CRTC disable callbacks since no one else would do that.

2016-08-08drm/mediatek: Fix mtk_atomic_complete for runtime_pmBibby Hsieh1-1/+16
To properly implement atomic w/ runtime pm, we move drm_atomic_helper_commit_modeset_enables() above drm_atomic_helper_commit_planes() to ensure CRTCs are enabled before modifying plane registers, and set active_only to true to filter out plane update notifications when the CRTC is disabled. According to the document from linux kernel: Set the active_only parameters to true in order not to receive plane update notifications related to a disabled CRTC. This avoids the need to manually ignore plane updates in driver code when the driver and/or hardware can't or just don't need to deal with updates on disabled CRTCs, for example when supporting runtime PM.

2016-06-21drm: Don't call drm_dev_set_unique from platform driversDaniel Vetter1-2/+0
Since commit e112e593b215c394c0303dbf0534db0928e87967 Author: Nicolas Iooss <[email protected]> Date: Fri Dec 11 11:20:28 2015 +0100 drm: use dev_name as default unique name in drm_dev_alloc() we're using a reasonable default which should work for everyone. Only mtk, rcar-du and sun4i are affected, and as kms-only drivers without any rendering support no one should ever care about the unique name v2: Rebase on top of mediatek.

2016-06-21drm/mediatek: Remove redundant calls to drm_connector_register_all()Chris Wilson1-7/+0
Up to now, the recommendation was for drivers to call drm_dev_register() followed by drm_connector_register_all(). Now that drm_connector_register() is safe against multiple invocations, we can move drm_connector_register_all() to drm_dev_register() and not suffer from any backwards compatibility issues with drivers not following the more rigorous init ordering.

- dev is redundant, we have state->atomic - add stall parameter, which must be set when swapping needs to stall for preceeding commits to stop looking at ->state pointers.
