Name
drm_atomic_clean_old_fb —
- Unset old_fb pointers and set plane->fb pointers.
Synopsis
void drm_atomic_clean_old_fb ( | struct drm_device * dev, |
| | unsigned plane_mask, |
| | int ret); |
Arguments
dev
drm device to check.
plane_mask
plane mask for planes that were updated.
ret
return value, can be -EDEADLK for a retry.
Description
Before doing an update plane->old_fb is set to plane->fb,
but before dropping the locks old_fb needs to be set to NULL
and plane->fb updated. This is a common operation for each
atomic update, so this call is split off as a helper.
