By the way, another question.
Is there a way to not compile the code regarding the VALE switch? I'm only
interested in using netmap with Tap Devices and NICs, so I was hoping to
save some memory.

You mean netmap_mem2.c ? It was there where I found the NETMAP_BUF_MAX_NUM
define.

Update:
I noticed that the netmap module was still crashing, after changing the
OpenWRT VM ram to 256MB. I now raised to 1GB and it no longer crashed. The
netmap module is now consuming about 350MB of Ram, which for my objectives
is just too much...

To Luigi and to whom may be able to help
Hello all.
Is it possible to reduce the size of the memory buffer allocated by the
netmap module?
I'm asking this because I was implementing some testing code, using NICs
and a Tap device in an OpenWRT VM with 64MB of RAM.
Because of the small RAM amount,
Hi Luigi.
Do you have presentations or tutorial code from that tutorial, that you can
share here?

I think the results presented at the paper are regarding one port sending
or receiving at 14.88Mpps. Using several ports at the same time will surely
give much lower results. But then again, if one wants 8, 16, 24 or even
more ports at 10Gb/s, then it should look for FPGA implementations.

I will try to keep regular updates on this situation.

OK, ignore what I said in the last e-mail. My Makefile is nor working
properly and I'm trying to figure out why. OpenWRT documentation for module
Makefiles creation is scarce and confuse...

Attached goes the output for the compile attempt. Maybe I'm missing
something very basic...

Luigi one question. Does netmap requires a processor with 64 bits? I'm
having some trouble in compiling netmap, using the same Makefile I used
previously, but for an Intel IXP435 CPU (Gateworks Cambria).

Sanuri, in order to achieve your goal, you should look for service
distribution over several systems (computers), basically a Cloud
architecture.
Depending on the language that your system is implemented, you should look
for the appropriate framework.

don't forget the header of the ping. the -s flag specifies the amount of
data that the ping carries. By specifying a size of 500, you are creating a
ping packet larger than the MTU.

Great! :)
I will give you the results as soon as I can get them :)

Just a remainder, so that the question doesn't get lost in time.

First of all, thank you for the quick answer!
I will try it myself to compile just the netmap module without the drivers
and report the results back to you.
Once again, thank you!

Hello!
First of all, to Luigi and the dev team, great piece of work that netmap
is! This is a piece of software that I was looking for quite some time.
Your team effort is appreciated!
Now the question.
I know that this is a FreeBSD mailing list but I was wondering, since you
have a PKGBUILD file
