Build igb_uio driver

cd ~/gitrepo
git clone https://github.com/daynix/dpdk-kmods.git
cd dpdk-kmods
make; sudo make install

Install copies the .ko to the right place:

cd /usr/lib/modules/$(uname -r)/extra/dpdk
sudo ln -s /home/advaadmin/gitrepo/dpdk-kmods/linux/igb_uio/igb_uio.ko igb_uio.ko

Align ice and i40e drivers

ORAN F/G Release documentation mentions the following versions for the fronthaul NIC drivers : • ice 1.3.2

wget https://downloadmirror.intel.com/30303/eng/ice-1.3.2.tar.gz

• i40e 2.14.13

In other place ORAN documentation mentioned the following versions:

  1. Intel® Ethernet 800 Series Linux Driver (ice) — 1.4.0 (or later)
  2. Wireless Edge DDP Package version (ice_wireless_edge) — 1.3.22.101 (WRONG)
  3. Intel® Ethernet 800 Series firmware version — 1.5.4.2 (or later)
  4. Intel® Ethernet 800 Series NVM version — 2.4 (or later)

Note, according to Intel, ‘firmware’ means to be the same as NVM https://www.intel.com/content/www/us/en/support/articles/000059457/ethernet-products.html

advaadmin@yrksrv03:~/gitrepo/6g-terafactory-ran$ sudo ethtool -i eno12399
driver: ice
version: 1.3.2
firmware-version: 3.00 0x80008943 20.5.13

First field is the firmware or NVM version (3.00). Second field is the EtrackID (0x80008943). Third field is the Combo Boot Image version (version of the BootIMG.FLB file).

Note about Xeon-D E800

On a server with Xeon(R) D-1734NT CPU we got the following results of NVM checking:

We can see that Xeon-D embedded E823-L chip is probably does not support eCPRI. We need to use a discrete E810-XXV-2 NIC.

DPDK and patched Columbiaville driver

wget http://fast.dpdk.org/rel/dpdk-20.11.3.tar.gz
tar -xvf dpdk-20.11.3.tar.gz
cd dpdk-stable-20.11.3
CC=icc meson x86_64-native-linuxapp-icc/
# cd x86_64-native-linuxapp-icc; ninja; sudo ninja install

DPDK ice driver is in librte_net_ice.so.21.0, keep this file for a reference with the different name. Now patch Columbiaville DPDK driver (file ice_ethdev.c ):

                PMD_DRV_LOG(INFO, "queue %d is binding to vect %d",
                            base_queue + i, msix_vect);
//AAA+
                // /* set ITR0 value */
                // ICE_WRITE_REG(hw, GLINT_ITR(0, msix_vect), 0x2);
        /* set ITR0 value */
        ICE_WRITE_REG(hw, GLINT_ITR(0, msix_vect), 0x10);
        /* set ITR0 value
         * Empirical configuration for optimal real time latency
         * reduced interrupt throttling to 2 ms
         * Columbiaville pre-PRQ : local patch subject to change
        */
        ICE_WRITE_REG(hw, GLINT_ITR(0, msix_vect), 0x1);
        ICE_WRITE_REG(hw, QRX_ITR(base_queue + i), QRX_ITR_NO_EXPR_M);
//AAA-

Wireless Edge DDP package

eCPRI parsing is introduced in Wireless Edge DDP package. To check the DDP package version:

dmesg | grep -i ddp
[ 4113.361991] ice 0000:f4:00.0: The DDP package was successfully loaded: ICE Wireless Edge Package version 1.3.10.0

ICE OS Default Package version 1.3.4.0 is not good for us, we need to set a suggested one:

wget https://downloadmirror.intel.com/772044/800%20Series%20DDP%20for%20Wireless%20Edge%20Package%201.3.10.0.zip

We need to put the package at certain place:

adva@portwell3:~$ ll /lib/firmware/intel/ice/ddp/

NOTE: DPDK 20.11 might be not compatible with ice_wireless_edge-1.3.10.0.pkg
