Hi Sorry for the late response, I'll be using an ARM processor for a 1G link.
My first issue came when doing what you suggested, and try the "emulated netmap mode". I need to cross compile the code from my x86, which I think I did correctly by setting up my arm toolchain and passing the kernel source when doing the "make". Now when I run the pkt-gen example I get : [ 57.602575] Unable to handle kernel paging request at virtual address f143ca04 [ 57.609740] pgd = 894c4000 [ 57.612420] [f143ca04] *pgd=00000000 [ 57.615973] Internal error: Oops: 5 [#1] PREEMPT SMP ARM Where I'm stuck since a while ago trying to figure it out. regards 2014-08-27 16:23 GMT-06:00 Luigi Rizzo <ri...@iet.unipi.it>: > > > > On Wed, Aug 27, 2014 at 3:18 PM, David <dajos...@gmail.com> wrote: > >> Hi, >> >> I'm needing to use netmap on a custom driver, I don't understand the >> content of the functions I need to implement and that are detailed on >> "PORTING" file. >> >> > sometimes (often, actually) the hw has bottlenecks that make native > netmap mode almost useless. > One thing you could try is the "emulated netmap mode" which > is used by default if the driver has no native support. > This is in the code on code.google.com/p/netmap/ , > the branch "next" (which is basically the code now in FreeBSD) > has some fixes for that specific feature > > cheers > luigi > > > can someone give a hand to understand it better? >> >> regards >> >> -- >> David Díaz Barquero >> >> Ingeniería en Computadores >> Tecnológico de Costa Rica >> _______________________________________________ >> freebsd-net@freebsd.org mailing list >> http://lists.freebsd.org/mailman/listinfo/freebsd-net >> To unsubscribe, send any mail to "freebsd-net-unsubscr...@freebsd.org" > > > > > -- > -----------------------------------------+------------------------------- > Prof. Luigi RIZZO, ri...@iet.unipi.it .
