Please could you explain why it is needed?
The variable V should be inherited by the recursive make.
It's working without your patch in my test.

Hi Thomas,

You are right. If you set V=1 in the commmand line it will inherit and pass it down.
In the curent framework, we do not force V to be 1, just to be defined (coud be V=y
or V=enable, etc).
This patch was just forcing the value to be 1 as it is the required value for the
kernel makefiles.

It is not a big deal and we could approach this by specifiying on the docs to be V=1
or any other way you think more appropiate?

Thanks,
Sergio

Oh OK, I didn't imagine passing other value to V ;)
It's better to fix makefile than doc. So I'm OK with this patch.

Sergio,

I'd like to see a v2 patch with your explanations in commit log
and with a Signed-off-by.

> > -		CROSS_COMPILE=$(CROSS)
> > +		V=$(if $(V),1,0) CROSS_COMPILE=$(CROSS)

Minor nits:
- paren is not needed for one letter variable
- V option should go to the end to keep things sorted by importance

-               CROSS_COMPILE=$(CROSS)
+               CROSS_COMPILE=$(CROSS) V=$(if $V,1,0)

> Acked-by: Pablo de Lara <pablo.de.lara.guarch@intel.com>

Please Pablo, do not give your ack if there is no Signed-off-by.
It's mandatory.

Thanks

My mistake, I will be more careful to check proper comments and signed-off.
V2 on the way.

I don't mind doing this but a quick grep on the current code
will show more single letters with parenthesis than without.
I was just trying to be consistent with current style.

Thanks,
Sergio

Linux kernel build system requires V=1 to enable verbose output, but
current DPDK framework just check if V is defined.

Fix: force V=1 when building Linux kernel modules if verbose output is
enabled.

Self-NACK.
Please ignore as I forgot to add v2 prefix.
