Re: [Xen-users] [Xen-devel] PCI passthrough problems after legacy update of xen 4.1

[Andreas Falck <falck.andreas.lists@xxxxxxxxx>]

Ok, I have some progress. It tried also with the device I had always managed to get through, the radeon 7790 gpu. This worked equally well with both versions of pciif.py. However, it turned out that with the changed version, if I pass the gpu first in the pci = [ ... ] list, the other devices also gets through. This was not the case with the original version of pciif.py.

If (and only if) i order the passthrough list in the config file so that it says

pci = [ '41:00.0', '41:00.1', '04:00.0' ]

(This corresponds to GPU, HDMI audio, USB at irqs 16, 17, 19) - then passthrough of all devices works with the new version of pciif.py ("if dev.irq:"), but not with the old version ("if not self.vm.info.is_hvm() and dev.irq:"). So the second failure seemingly has to do with some property set or checked only for the first passed through device. Logs follow:

WORKING setup:
pci = [ '41:00.0', '41:00.1', '04:00.0' ]

NEW pciif.py (if dev.irq)

2013/5/2 Andreas Falck <falck.andreas.lists@xxxxxxxxx>

Ok, I changed so that the corresponding first lines of code looks like this:
   
        if dev.irq: 
            rc = xc.physdev_map_pirq(domid = fe_domid,
                                   index = dev.irq,
                                   pirq  = dev.irq)

(only the first line changed)

Then, after restarting xend, I get a different failure on line 346, which is the last line of the above: "VmError: (17, 'File exists')". Full xend.log attached below.

I can also do tests with the one device which I still manage to pass through (a gpu), if I get specific suggestions on what to look for.
