2018-05-21uvc-gadget: Use events libraryPaul Elder
Replace the manual implementation of the select-based event loop with the events library. This cleans up the code and simplifies event handling. Signed-off-by: Paul Elder <paul.elder@ideasonboard.com> Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2018-05-20uvc-gadget: Use new kernel API headerLaurent Pinchart
The UVC gadget driver now defines its API in the linux/usb/g_uvc.h public header, use it instead of including an internal kernel header through a relative path. The public API doesn't define the UVC_INTF_CONTROL and UVC_INTF_STREAMING macros, define them locally until we can get rid of them. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
2017-03-06uvc-gadget: Do not send Set Interface (alternate setting) response twiceRoger Quadros
On alternate setting change, the webcam gadget sends us a UVC_EVENT_STREAMON or UVC_EVENT_STREAMOFF event. In the first case, the driver will issue a delayed status response automatically when we call the VIDIOC_STREAMON ioctl. In the second case, the driver sends the status response immediately. We must thus not send the status response manually with UVCIOC_SEND_RESPONSE in any of those cases. Without this, the ISO streaming doesn't work if host application (e.g. luvcview) is closed and restarted. On dwc3 gadget controller it was resulting in Buffer Expiry error on the ISO endpoint.
