Re: [dpdk-users] Firmware assertion fails with BCM57840 card

[Justas Poderys <juspo@fotonik.dtu.dk>]

TL DR: Solved by downloading bnx2x-e2-7.2.51.0.fw and bnx2x-e1h-7.2.51.0.fw from https://github.com/cernekee/linux-firmware/tree/master/bnx2x
And placing in /lib/firmware/bnx2x

Long story:

Recompiling drivers and running with --log-level 10 gave indication where the problem was:

juspo@TOR1CN:~/dpdk-stable-16.11.1$ sudo -E ./x86_64-native-linuxapp-gcc/app/testpmd --log-level 10
<snip>
PMD: bnx2x_load_firmware(): Can't open firmware file

Looking at drivers/net/bnx2x/bnx2x.c:

#define FW_NAME_57711 "/lib/firmware/bnx2x/bnx2x-e1h-7.2.51.0.fw"
#define FW_NAME_57810 "/lib/firmware/bnx2x/bnx2x-e2-7.2.51.0.fw"

void bnx2x_load_firmware(struct bnx2x_softc *sc)
{
        <snip>
        fwname = sc->devinfo.device_id == CHIP_NUM_57711
                ? FW_NAME_57711 : FW_NAME_57810;
        f = open(fwname, O_RDONLY);
        if (f < 0) {
                PMD_DRV_LOG(NOTICE, "Can't open firmware file");
                return;
        }
}

Seems that driver is looking for a file that is not there. Ubuntu 16.04.02 comes with:

juspo@TOR1CN:~/dpdk-stable-16.11.1$ ls /lib/firmware/bnx2x/
bnx2x-e1-7.12.30.0.fw  bnx2x-e1h-7.12.30.0.fw  bnx2x-e2-7.13.1.0.fw
bnx2x-e1-7.13.1.0.fw   bnx2x-e1h-7.13.1.0.fw   bnx2x-e2-7.12.30.0.fw 

Downloading missing firmware files from https://github.com/cernekee/linux-firmware/tree/master/bnx2x
Made dpdk work.

Hello all,

I am trying to setup dpdk on a server with BCM57840 card, however I cannot get testpmd to run due to the assertion failure:

juspo@TOR1CN:~/dpdk-stable-16.11.1$ sudo -E ./x86_64-native-linuxapp-gcc/app/testpmd -c 0xf -n 4 -- -i
EAL: Detected 24 lcore(s)

EAL: VFIO support initialized

Aborted (core dumped)

Details of my system:

juspo@TOR1CN:~/dpdk-stable-16.11.1$ sudo -E ~/dpdk-stable-16.11.1/tools/dpdk-devbind.py --status

Network devices using DPDK-compatible driver ============================================
0000:15:00.0 'BCM57840 NetXtreme II 10 Gigabit Ethernet' drv=igb_uio unused=bnx2x,vfio-pci
0000:15:00.1 'BCM57840 NetXtreme II 10 Gigabit Ethernet' drv=igb_uio unused=bnx2x,vfio-pci

I was following the guide available at http://www.dpdk.org/doc/guides/nics/bnx2x.html when trying to setup the system.

Thanks for any help.

BR,
~Justas
