2016-06-07drm/core: Change declaration for gamma_set.Maarten Lankhorst1-4/+6
Change return value to int to propagate errors from gamma_set, and remove start parameter. Updates always use the full size, and some drivers even ignore the start parameter altogether. This is needed for atomic drivers, where an atomic commit can fail with -EINTR or -ENOMEM and should be restarted. This is already and issue for drm_atomic_helper_legacy_set_gamma, which this patch fixes up. Changes since v1: - Fix compiler warning.

One step closer to dropping all the drm_bus_* code: Add a driver->set_busid() callback and make all drivers use the generic helpers. Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe).

2014-07-08drm: Introduce drm_fb_helper_prepare()Thierry Reding1-1/+3
To implement hotplug detection in a race-free manner, drivers must call drm_kms_helper_poll_init() before hotplug events can be triggered. Such events can be triggered right after any of the encoders or connectors are initialized. At the same time, if the drm_fb_helper_hotplug_event() helper is used by a driver, then the poll helper requires some parts of the FB helper to be initialized to prevent a crash. At the same time, drm_fb_helper_init() requires information that is not necessarily available at such an early stage (number of CRTCs and connectors), so it cannot be used yet. Add a new helper, drm_fb_helper_prepare(), that initializes the bare minimum needed to allow drm_kms_helper_poll_init() to execute and any subsequent hotplug events to be processed properly.
