Doubtful this will matter to many (any?), but maybe it'll save someone some
time.

Why are you adding newlines to log message strings? Shouldn't that be up to
whatever the messages end up getting routed to?

PMD_LOG is a lot more useful it if easily integrates with central logging

FWIW, it surprised the heck out of me as well.
Turns out that even though I'm compiling in 64-bit mode, gcc has
sizeof(int) as 4 bytes rather than 8. Not really sure what the scoop is on
that, but the standard leaves that up to the compiler. I'm used to int
always being the "natural size" on the C
gmail.com email rather than a corporate email
hosted via google apps.

Environment:
* DPDK 1.6.0r2
* Ubuntu 14.04 LTS
* kernel: 3.13.0-38-generic
When we start exercising KNI a fair bit (transferring files across it, both
sending and receiving), I'm starting to see a fair bit of these kernel
lockups:
kernel: BUG: soft lockup - CPU#1 stuck for 22s! [kni_single:
k at the kernel messages. I will be glad to look at it.

Hi Reshma,
A few comments and questions about your design...
1) How do you envision the reorder library to be used? Based on the
description, it seems like the expectation is that packet order would be
maintained at either the interface/port level or maybe at the RX queue
level. Is that right or
kes
more sense in that context.
More detailed responses to your previous answers inline.
Regards,
Jay

Tim,
Thanks for sharing this. If nothing else, I wanted to at least provide some
feedback on the parts that look useful to me for my applications/product.

Can you improve the comments on these counters? If you didn't happen to
follow this thread, there's no way to reasonably figure out what the
difference is from looking at the code without chasing it all the way down
and cross-referencing the NIC datasheet.
Thanks,
Jay

I just went through this a few months ago when I was integrating DPDK port
stats into our stat tracking system.
I appreciate you making the extra effort to make this clearer for app
developers :-)

Back when this was first submitted in June, I mentioned that
CLOCK_MONOTONIC_RAW was ~10x slower than CLOCK_MONOTONIC:
http://dpdk.org/ml/archives/dev/2015-June/018687.html
It's not completely free from NTP frequency adjustments, but it won't have
any discontinuities.
That's what we've been usin

Most of the code in sort_by_physaddr() should be replaced by a call to
qsort() instead. Less code and gets rid of an O(n^2) sort. It's only init
code, but given how long EAL init takes, every bit helps.
I submitted a patch for this close to a year ago:

Maybe I just haven't had enough caffeine this morning yet, but why would
you add IP reassembly to KNI? If packets are going through KNI, they
already have IP reassembly via the normal Linux networking stack...

Don't need the 'safe' version of list_for_each_entry() if you aren't deleting
from the list as you iterate over it

No reason to check out many entries are in kni->rx_q prior to
actually pulling them from the fifo. You can't dequeue more than
are there anyway. Max entries to dequeue is either the max batch
size or however much space is available on kni->free_q (lesser of the two)
Signed-off-by:
Loop processing packets dequeued from rx_q was using the number of
packets requested, not how many it actually received.
Variable rename to make code a little more clear

Some sort of hiccup sending. Not sure why 2/3 didn't come out as expected.
I'll try sending again.
