Bhupesh Sharma [Fri, 1 Mar 2013 19:46:31 +0000 (20:46 +0100)]
usb: gadget: uvc: Make video streaming buffer size comply with USB3.0 SS

As per the USB3.0 specs, the bandwidth requirements of a UVC's video
streaming endpoint will change to support super-speed. These changes
will be dependent on whether the UVC video streaming endpoint is Bulk or
Isochronous:

- If video streaming endpoint is Isochronous:
  As per Section 4.4.8.2 (Isochronous Transfer Bandwidth Requirements)
  of the USB3.0 specs:

    A SuperSpeed isochronous endpoint can move up to three burst
    transactions of up to 16 maximum sized packets (3 * 16 * 1024 bytes)
    per service interval.

- If video streaming endpoint is Bulk:
  As per 4.4.6.1 (Bulk Transfer Data Packet Size) of the USB3.0 specs:

    An endpoint for bulk transfers shall set the maximum data packet
    payload size in its endpoint descriptor to 1024 bytes. It also
    specifies the burst size that the endpoint can accept from or
    transmit on the SuperSpeed bus. The allowable burst size for a bulk
    endpoint shall be in the range of 1 to 16.

So, in the Isochronous case, we can define the USB request's buffer to
be equal to = (Maximum packet size) * (bMaxBurst + 1) * (Mult + 1), so
that the UDC driver can try to send out this buffer in one Isochronous
service interval.

The same computation will hold good for the Bulk case as the Mult
value is 0 here and we can have a USB request buffer of maximum
16 * 1024 bytes size, which can be sent out by the UDC driver as
per the Bulk bandwidth allocation on the USB3 bus.

This patch adds the above-mentioned support and is also USB2.0 backward
compliant.

11 years agousb: gadget: uvc: Delay the status stage when setting alternate setting 1
Bhupesh Sharma [Fri, 1 Mar 2013 19:46:30 +0000 (20:46 +0100)]
usb: gadget: uvc: Delay the status stage when setting alternate setting 1

This patch adds the support in UVC webcam gadget design for providing
USB_GADGET_DELAYED_STATUS in response to a set_interface(alt setting 1)
command issue by the Host.

The current UVC webcam gadget design generates a STREAMON event
corresponding to a set_interface(alt setting 1) command from the Host.
This STREAMON event will eventually be routed to a real V4L2 device.

To start video streaming, it may be required to perform some register
writes to a camera sensor device over slow external busses like I2C or
SPI. So, it makes sense to ensure that we delay the STATUS stage of the
set_interface (alt setting 1) command.

Otherwise, a lot of ISOC IN tokens sent by the Host will be replied to
by zero-length packets by the webcam device. On certain Hosts this may
even lead to ISOC URBs been cancelled from the Host side.

So, as soon as we finish doing all the "streaming" related stuff on the
real V4L2 device, we call a STREAMON ioctl on the UVC side and from here
we call the 'usb_composite_setup_continue' function to complete the
status stage of the set_interface(alt setting 1) command.

Further, we need to ensure that we queue no video buffers on the UVC
webcam gadget, until we de-queue a video buffer from the V4L2 device.
So, the application should call the STREAMON on UVC side only when it
has dequeued sufficient buffers from the V4L2 side and queued them to
the UVC gadget.
