3) I used kernel 3.13.something

If the TBS driver works, why don't you use it?
1) driver is not stable in 24x7 setups
2) driver use old DVBAPI. This cause problems with some

We have two kinds of PCIe cards:

lack IOMMU or have disabled IOMMU
special way?
How?
Where (PCI bridge driver? card's driver?)?
Any examples in kernel?
Thank you.

t fully fixed?
d) Receiver's driver: likely
Questions:
1) What 'domain=0x001c' mean?
2) Where I can find definition of possible flags?
3) What kind of address is written in message?
- physical?
- virtual?
- address from devices point of view?
Thank you.
