Hi Manu,
Do you know if your saa716x driver might have any issue in the dma code?
The code doesn't seem to be using chained scatterlists so it should be
ok with the "old" method of just increment the pointer instead of
using sg_next.
(It's still a little blurry to my this IOMMU+dma+scatterlist stu

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
user space programs.

If the TBS driver works, why don't you use it?
The WARNING from the kernel log indicates a hardware bug in the PCIe
bridge. Do you have the same card, and do you also get this warning
with kernel 3.16?

In theory, such a switch should be

We have two kinds of PCIe cards:
A1 - based on chip B
A2 - based on same chip B but behind PCIe switch
Card A1 work flawlessly in any configuration,
but card A2 work flawlessly only if system
lack IOMMU or have disabled IOMMU
Questions:
Do we have to treat card with PCIe switch in specia
