Might be off-topic but do we need to check somewhere in odp tests that cpu
frequency scaling is turend off? My latop likes to play with frequencies
and even warn up does not work because it goes to maximum speed, then
overheated and cpu frequency lowered. If we count time in cpu cycles -
measuremen
I've been playing around with odp_bench_packet and there are two
problems with using this test:
1. The test performs multiple runs of each test TEST_SIZE_RUN_COUNT
times, which is good, however it only reports the average cycle time
for these runs, There is considerable variability when running in
Please ignore v2. It had a memory leak that Matias' excellent
odp_bench_packet test found. A corrected v3 is posted at

Hi Petri,
I've posted v2 of the tuning patch at
http://patches.opendataplane.org/patch/7878/ which adds optimization
to the odp_packet_free_multi() routine as well as odp_packet_free().
So both of these should now be a very similar for freeing reference
and non-reference packets.
I'd still like a
I've posted patch http://patches.opendataplane.org/patch/7857/ as an
initial step towards resolving this issue. Petri: can you make your
test program available to me so I can try to reproduce your results
locally. I don't have quite the scale or controlled environment that
you do but this should sa

Implement the APIs:
- odp_packet_ref_static()
- odp_packet_ref()
- odp_packet_ref_pkt()
- odp_packet_is_ref()
- odp_packet_unshared_len()
This also involves functional upgrades to the existing packet manipulation
APIs to work with packet references as input arguments.
