I found the card worked in Dom0 with Xen loaded. After some trial and

1) I'd used "pciback.hide ..." instead of the newer "xen-pciback.hide

2) Then in DomU I needed to use "iommu=soft" and not "swiotlb=force"
Spoke too soon :(
It *was* working, then I upgraded the memory in the server. After a
morning spent trying various permutations*, I've determined that my
setup works with 1G or 4G RAM, but not with 5G or 8G.
Any suggestions what I'm missing ? IS there something I need to change
with >4G RAM ?
To recap, I'm trying to run MythTV in a PV guest with one HVR-1200 DVB
Tuner made available via pciback.hide.
Xen, Dom0, DomU all from Debian stable (Squeeze) - Xen 4.0.1, kernel
2.6.32-xen.
AND64 - HP Proliant Microserver
I no longer have the setup available to test as I moved MythTV to a
seperate server. I can confirm however that the server I was trying to
setup did in fact have 8GB of RAM. I never thought to reduce this to test.
If you add the following line to /etc/default/grub
GRUB_CMDLINE_XEN="dom0_mem=512M"
You could restrict the amount of RAM available to the dom0, would that
make it work in dom0? A stab in the dark, I know.
