Haihao Xiang 23967fc02b libs: display: drm: fix set_device_path_from_fd ... drmGetBusid() (GET_UNIQUE ioctl) won't return a valid bus id when drmSetInterfaceVersion() (SET_VERSION ioctl) hasn't been called(see[1]), so we can't get the right device path. Running test-display will get the error below: ** (test-display:18630): ERROR **: 10:26:00.434: could not create Gst/VA display Calling drmSetInterfaceVersion() before drmGetBusid() can't fix this issue because a special permission is required for SET_VERSION ioctl. This patch retrieves the device path from file descriptor via g_file_read_link() [1] https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/drm_ioctl.c#L48-L104 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer-vaapi/-/merge_requests/412>		2021-01-28 09:48:56 +08:00
