vkGetDrmDisplayEXT

Before acquiring a display from the DRM interface, the caller may want to select a specific VkDisplayKHR handle by identifying it using a connectorId. To do so, call:

VkResult vkGetDrmDisplayEXT(
    VkPhysicalDevice physicalDevice,
    int32_t drmFd,
    uint32_t connectorId,
    VkDisplayKHR* display);

pub fn get_drm_display_ext(
    physical_device: vk::PhysicalDevice,
    drm_fd: i32,
    connector_id: u32,
    display: *mut vk::DisplayKHR,
) -> vk::Result;

• physicalDevice is the physical device to query the display from.
• drmFd is the DRM primary file descriptor.
• connectorId is the identifier of the specified DRM connector.
• pDisplay is a pointer to a VkDisplayKHR handle where the display is returned.

If there is no VkDisplayKHR corresponding to the connectorId on the physicalDevice, the returned display will be VK_NULL_HANDLE. The provided drmFd must correspond to the one owned by the physicalDevice. If not, the error code VK_ERROR_UNKNOWN will be returned. Mast⁠er permissions are not required, because the file descriptor is just used for information gathering purposes. The given connectorId must be a resource owned by the provided drmFd. If not, the error code VK_ERROR_UNKNOWN will be returned. If any error is encountered during the identification of the display, the call must return the error code VK_ERROR_INITIALIZATION_FAILED.
