[linux-uvc-devel] Multi transactions not working

Hi,
We have back ported the UVC class driver from 2.6.36 to 2.6.29. Our USB device driver max packet size works for 1024. We have changed the UVC streaming descriptor as below for multi transfers:

static struct usb_endpoint_descriptor uvc_streaming_ep = {
         .bLength                = USB_DT_ENDPOINT_SIZE,
         .bDescriptorType        = USB_DT_ENDPOINT,
         .bEndpointAddress       = USB_DIR_IN,
         .bmAttributes           = USB_ENDPOINT_XFER_ISOC,
         .wMaxPacketSize         = cpu_to_le16(1024 | 0x1000),
         .bInterval              = 1,
 };

When we observe the packets on USB bus in analyzer, the status is successful for all the packets. But there is no color pattern on Windows-7 host Skype application.

Note: It is working for   .wMaxPacketSize         = cpu_to_le16(1024), but not working for multi transactions. Please help in this regard. We are using uvc-gadget application to test the same.

Thanks,
Rajb

Hi,
I am trying to transfer USB high bandwidth(1024x3 bytes of data in every 125 us) isochronous data with UVC class driver. It is working for 1024 bytes (YUV) in every125 us, but unable to stream for high bandwidth transfers.

HW & SW details:
1. Reference client board(OTG USB 2.0 Device I/F) -->usb cable -->Windows-7 Host PC
2. Client OS: Linux-2.6.29
3. UVC gadget class driver: back ported from Linux-2.6.36
4. Client side application: uvc-gadget application
5. Windows-7 Host PC applications: VLC player and Skype
6. Resolution: 640x360 15fps

The Windows-7 host PC is detecting the device as UVC video, checked the isochronous transfers on USB bus with monitor tool.

The following changes made to the client UVC driver files:

Linux/drivers/usb/gadget/f_uvc.c :
-----------------------------------------
static struct usb_endpoint_descriptor uvc_streaming_ep = {
         .bLength                = USB_DT_ENDPOINT_SIZE,
         .bDescriptorType        = USB_DT_ENDPOINT,
         .bEndpointAddress       = USB_DIR_IN,
         .bmAttributes           = USB_ENDPOINT_XFER_ISOC,
         //.wMaxPacketSize         = cpu_to_le16(512),
         .wMaxPacketSize         = cpu_to_le16(1024 | 0x1000),
         .bInterval              = 1,
 };


Linux/drivers/usb/gadget/uvc_video.c:
-----------------------------------------------
static int
uvc_video_alloc_requests(struct uvc_video *video)
 {
         unsigned int i;
         int ret = -ENOMEM;
 
         BUG_ON(video->req_size);
 
         for (i = 0; i < UVC_NUM_REQUESTS; ++i) {
                 //video->req_buffer[i] = kmalloc(video->ep->maxpacket, GFP_KERNEL);
                 video->req_buffer[i] = kmalloc(1024 * 3, GFP_KERNEL);

                 if (video->req_buffer[i] == NULL)
                         goto error;
 
                 video->req[i] = usb_ep_alloc_request(video->ep, GFP_KERNEL);
                 if (video->req[i] == NULL)
                         goto error;

                 video->req[i]->buf = video->req_buffer[i];
                 video->req[i]->length = 0;
                 video->req[i]->dma = DMA_ADDR_INVALID;
                 video->req[i]->complete = uvc_video_complete;
                 video->req[i]->context = video;
 
                 list_add_tail(&video->req[i]->list, &video->req_free);
         }
 
         //video->req_size = video->ep->maxpacket;
         video->req_size = 1024 * 3;

         return 0;
 
error:
        uvc_video_free_requests(video);
         return ret;
}


What else do we need to change for 1024*3 high bandwidth transfers? Please help in this regard.

Thanks,
Rajb.

We have started testing our UVC camera with Linux Ubuntu-10.04.4 LTS host.

I am trying to transfer USB high bandwidth(1024x3 bytes of data in every 125 us) isochronous data with UVC class driver. It is working for 1024 bytes (YUV) in every125 us, but unable to stream for high bandwidth transfers.

HW & SW details:
1. Reference client board(OTG USB 2.0 Device I/F) -->usb cable -->Windows-7 Host PC
2. Client OS: Linux-2.6.29
3. UVC gadget class driver: back ported from Linux-2.6.36
4. Client side application: uvc-gadget application
5. Windows-7 Host PC applications: VLC player and Skype
6. Resolution: 640x360 15fps

The Windows-7 host PC is detecting the device as UVC video, checked the isochronous transfers on USB bus with monitor tool.

The following changes made to the client UVC driver files:

Linux/drivers/usb/gadget/f_uvc.c :
-----------------------------------------
static struct usb_endpoint_descriptor uvc_streaming_ep = {
         .bLength                = USB_DT_ENDPOINT_SIZE,
         .bDescriptorType        = USB_DT_ENDPOINT,
         .bEndpointAddress       = USB_DIR_IN,
         .bmAttributes           = USB_ENDPOINT_XFER_ISOC,
         //.wMaxPacketSize         = cpu_to_le16(512),
         .wMaxPacketSize         = cpu_to_le16(1024 | 0x1000),
         .bInterval              = 1,
 };


Linux/drivers/usb/gadget/uvc_video.c:
-----------------------------------------------
static int
uvc_video_alloc_requests(struct uvc_video *video)
 {
         unsigned int i;
         int ret = -ENOMEM;
 
         BUG_ON(video->req_size);
 
         for (i = 0; i < UVC_NUM_REQUESTS; ++i) {
                 //video->req_buffer[i] = kmalloc(video->ep->maxpacket, GFP_KERNEL);
                 video->req_buffer[i] = kmalloc(1024 * 3, GFP_KERNEL);

                 if (video->req_buffer[i] == NULL)
                         goto error;
 
                 video->req[i] = usb_ep_alloc_request(video->ep, GFP_KERNEL);
                 if (video->req[i] == NULL)
                         goto error;

                 video->req[i]->buf = video->req_buffer[i];
                 video->req[i]->length = 0;
                 video->req[i]->dma = DMA_ADDR_INVALID;
                 video->req[i]->complete = uvc_video_complete;
                 video->req[i]->context = video;
 
                 list_add_tail(&video->req[i]->list, &video->req_free);
         }
 
         //video->req_size = video->ep->maxpacket;
         video->req_size = 1024 * 3;

         return 0;
 
error:
        uvc_video_free_requests(video);
         return ret;
}


What else do we need to change for 1024*3 high bandwidth transfers? Please help in this regard.

Thanks,
Rajb.

Hi,
We have back ported the UVC class driver from 2.6.36 to 2.6.29. Our USB device driver max packet size works for 1024. We have changed the UVC streaming descriptor as below for multi transfers:

static struct usb_endpoint_descriptor uvc_streaming_ep = {
         .bLength                = USB_DT_ENDPOINT_SIZE,
         .bDescriptorType        = USB_DT_ENDPOINT,
         .bEndpointAddress       = USB_DIR_IN,
         .bmAttributes           = USB_ENDPOINT_XFER_ISOC,
         .wMaxPacketSize         = cpu_to_le16(1024 | 0x1000),
         .bInterval              = 1,
 };

When we observe the packets on USB bus in analyzer, the status is successful for all the packets. But there is no color pattern on Windows-7 host Skype application.

Note: It is working for   .wMaxPacketSize         = cpu_to_le16(1024), but not working for multi transactions. Please help in this regard. We are using uvc-gadget application to test the same.

Thanks,
Rajb

So far i see, it has nothing todo with uvcvideo driver itself. It is usb
level issue, or more precisely usb controller issue. You can try
software usb monitor to investigate it. If it won't be able to provide
enough information, then you will need hardware usb analyser.

So far i see, it has nothing todo with uvcvideo driver itself. It is usb
level issue, or more precisely usb controller issue. You can try
software usb monitor to investigate it. If it won't be able to provide
enough information, then you will need hardware usb analyser.
