Hello,
I found a peculiarity in the vm_power_manager example on DPDK 2.2 if you use an installed copy of DPDK to compile the examples instead of the master copy (while trying to update some outdated stuff in my build system).
mhall@mvs-01:~/dpdk/examples/vm_power_manager$ fgrep -ir channel_commands *.{c,h}
channel_manager.c:#include "channel_commands.h"
channel_monitor.c:#include "channel_commands.h"
vm_power_cli.c:#include "channel_commands.h"
channel_manager.h:#include "channel_commands.h"
It appears a bunch of these files are trying to pull in this special header from here:
/home/mhall/src/sdn_sensor/external/dpdk/lib/librte_power/channel_commands.h
However this file is never copied into the include directions in the installed copy. So this example fails to build.
Did anybody run into this before?
Thanks,
Matthew.

Yes, the problem exists at least since DPDK 2.1 but somehow never
remembered to report / do something about it.
Basically either vm_power_manager example is messing with things its not
supposed to, or librte_power library isn't exporting everything needed
to fully use the it. Unfortunately both the library and the example are
lacking a maintainer :-/

Exact, you got the point.
I suggest to disable this feature in your config.
If it's really annoying, you are allowed to request the removal of the code.
I believe someone would maintain it if he has an interest.

I take it you mean disabling librte_power entirely, not just the example?

I can certainly submit a patch to disable it by default in the configs
(seems reasonable unmaintained code would default to off) and add a
deprecation note along the lines of "if no maintainer steps up, this
code will be removed in 16.07" if you like :)

Before sending such notice, we should wait for comments of some known
contributors to librte_power.
Alan, Pablo, what is your opinion?

Hi,
We will look from a maintainer from the Intel DPDK team and try resolve the
open issues.

John
