Detailed Description

struct drm_client_funcs - DRM client callbacks

Member Data Documentation

free

void(* drm_client_funcs::free) (struct drm_client_dev *client)

@free:

Called when the client gets unregistered. Implementations should release all client-specific data and free the memory.

This callback is optional.

hotplug

int(* drm_client_funcs::hotplug) (struct drm_client_dev *client)

@hotplug:

Called on drm_kms_helper_hotplug_event(). This callback is not called after @unregister has been called.

This callback is optional.

owner

struct module* drm_client_funcs::owner

@owner: The module owner

restore

int(* drm_client_funcs::restore) (struct drm_client_dev *client, bool force)

@restore:

Called on drm_lastclose(). The first client instance in the list that returns zero gets the privilege to restore and no more clients are called. This callback is not called after @unregister has been called.

Note that the core does not guarantee exclusion against concurrent drm_open(). Clients need to ensure this themselves, for example by using drm_master_internal_acquire() and drm_master_internal_release().

If the caller passes force, the client should ignore any present DRM master and restore the display anyway.

This callback is optional.

resume

int(* drm_client_funcs::resume) (struct drm_client_dev *client)

@resume:

Called when resuming the device from suspend.

This callback is optional.

suspend

int(* drm_client_funcs::suspend) (struct drm_client_dev *client)

@suspend:

Called when suspending the device.

This callback is optional.

unregister

void(* drm_client_funcs::unregister) (struct drm_client_dev *client)

@unregister:

Called when &drm_device is unregistered. The client should respond by releasing its resources using drm_client_release().

This callback is optional.
