/** |
|
* struct drm_mode_get_connector - Get connector metadata. |
|
* |
|
* User-space can perform a GETCONNECTOR ioctl to retrieve information about a |
|
* connector. User-space is expected to retrieve encoders, modes and properties |
|
* by performing this ioctl at least twice: the first time to retrieve the |
|
* number of elements, the second time to retrieve the elements themselves. |
|
* |
|
* To retrieve the number of elements, set @count_props and @count_encoders to |
|
* zero, set @count_modes to 1, and set @modes_ptr to a temporary struct |
|
* drm_mode_modeinfo element. |
|
* |
|
* To retrieve the elements, allocate arrays for @encoders_ptr, @modes_ptr, |
|
* @props_ptr and @prop_values_ptr, then set @count_modes, @count_props and |
|
* @count_encoders to their capacity. |
|
* |
|
* Performing the ioctl only twice may be racy: the number of elements may have |
|
* changed with a hotplug event in-between the two ioctls. User-space is |
|
* expected to retry the last ioctl until the number of elements stabilizes. |
|
* The kernel won't fill any array which doesn't have the expected length. |
|
* |
|
* **Force-probing a connector** |
|
* |
|
* If the @count_modes field is set to zero and the DRM client is the current |
|
* DRM master, the kernel will perform a forced probe on the connector to |
|
* refresh the connector status, modes and EDID. A forced-probe can be slow, |
|
* might cause flickering and the ioctl will block. |
|
* |
|
* User-space needs to force-probe connectors to ensure their metadata is |
|
* up-to-date at startup and after receiving a hot-plug event. User-space |
|
* may perform a forced-probe when the user explicitly requests it. User-space |
|
* shouldn't perform a forced-probe in other situations. |

* &DRM_MODE_PROP_ENUM or &DRM_MODE_PROP_BITMASK, allocate an array for |
