Hello readers,
We are currently targetting a new release (1.8.0) in few weeks.
It would be good to have most of the important pending patches in.
But writing and sending code is only the first part. After come the reviews.
Before integration, we need to validate the design of the new features,

Hi Satish,
Yes, you can change the pipe configuration during run-time, but in a slightly
different way. The way to do it is by defining multiple pipe profiles at the

run-time.
The pipe profiles are statically defin

The unit test can be used to measure cycles per packet in different rx/tx
rouines.
The NIC works in loopback mode. So it doesn't require test equipment to measure
throughput.
As result, the unit test shows the average cycles per packet consuming.
When doing the test, make sure the link is UP.

Hi,
My question is that if the Poll mode driver used the DMA kernel interface
to set up its mappings appropriately, would it still require that iommu=pt
be set?
What is the purpose of setting iommu=pt ?
Thank you.
Thanks a lot Cristian!!
It is really helpful information.

On closer inspection, I see that DPDK is simply using pthreads and
