Passthrough Digital Devices Cine S2 no Signal

[chvb]

Hello together,

 

after i had much Problem with Passthrough with a HP Server i bought new Hardware.

I successfully passed a Nvidia GTX 750 to a Windows VM with KVM.

 

Now i would like to passthrough my 2 Digital Devices Cine S2 Tuner Cards.

I used this Code in the Windows 10 Template.

 

 

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x03' slot='0x00' function='0x0'/>
      </source>
    </hostdev>

 

    <hostdev mode='subsystem' type='pci' managed='yes'>
      <driver name='vfio'/>
      <source>
        <address domain='0x0000' bus='0x04' slot='0x00' function='0x0'/>
      </source>
    </hostdev>

 

After that, i installed the Drivers of these Cards. In the Device Manager the two Cards where shown.

Now, when i tune a channel in DVBViewer, the Card show 0% Signal.There is no picture.

 

Transitional I use now the TVHeadend Docker with SATIP to the DVBViewer. This is solution is working.

But i want to passthrough the Cards to the VM.

 

thanks for any suggestions

Nobody?

 

- I've checked, if it works with only one Card because of same Vendor ID

- installed original bzroot & bzimage without DVB drivers.

- tested with syslinux command line

  append pcie_acs_override=downstream vfio-pci.ids=dd01:0003 initrd=/bzroot 

- each card is in her own IOMMU Group

 

The Cards are shown in device Manager of Windows 10. DVBViewer Software can find the Cards. But there are still no Signal.

 

thanks for any help
