Re: [libvirt-users] [Qemu-devel] VFIO PCIe Extended Capabilities
Hey Alex,
How so? The patch should make extended config space disappear when
the
device is not on a PCIe bus. This is the correct behavior per the
PCIe spec. Are you trying to exploit this QEMU bug to see some PCIe
capabilities but not others? That's wrong, you'll need to move the
device to a PCIe slot to get extended capabilities.
Yes, I am exploiting the peculiarities of QEMU to make my hardware work properly. It may
be wrong but it works (hence the ;-) ) .
From this conversation, it seems the real problem is that libvirt does
not auto assign the hardware to a pcie root port in the q35 machine type. It seems like
this really needs to be fixed in the libvirt source code; so, I'm working on a patch
for libvirt.
I'd be happy to test your patch for you; I have access to hardware that will allow me
to verify that your patch works correctly. Feel free to cc me on the next version of the
patch and I'll add my tested-by.
You're sending email to a public list, please stop including
these.
This is not intentional. It seems like the Xilinx email servers (not my local machine)
are adding this to all messages. I'll see what I can do and I'm sorry for the
inconvenience.
Thanks,
Spenser
