Does petalinux 2018.3 support 10G ethernet?

[astrome]

Hi, I'm using petalinux 2018.3 and I want to upgrade my design from 1G(using the PHY present on my custom board with virtex ultrascale+ (XCVU9P)) to 10G Ethernet(Using Xilinx 10G ethernet subsystem + SFP) but I didn't find any information about the Linux kernel. Does petalinux 2018.3, support to 10G Ethernet as primary ethernet?

[stephenm]

Yes, this is supported in Linux. Are you seeing any issues?

[astrome]

@stephenmYes. We are unable to find the XXV_ethernet_0 entry in the petalinx-config -> ethernet settings option. The hdf file and dts has entries for it.

[stephenm]

https://xilinx-wiki.atlassian.net/wiki/spaces/A/pages/18842485/Linux+AXI+Ethernet+driver

CONFIG_ETHERNET
CONFIG_NET_VENDOR_XILINX
CONFIG_XILINX_AXI_EMAC
CONFIG_AXIENET_HAS_MCDMA (Select this option In the design if Axi Ethernet is configured with Axi MCDMA)
CONFIG_XILINX_PHY (For testing SGMII/1000Base-x Configuration with PCS/PMA Core)

What IP are you using with this; the mcdma, dma or fifo?

[astrome]

@stephenm 

CONFIG_ETHERNET  =y
CONFIG_NET_VENDOR_XILINX =y
CONFIG_XILINX_AXI_EMAC =y
CONFIG_AXIENET_HAS_MCDMA   N/A we are not using it right now.  (Select this option In the design if Axi Ethernet is configured with Axi MCDMA)
CONFIG_XILINX_PHY =y

I have configured 10G the following way. When I added it to the design I dont see the XXV_ethernet (10G). See the screenshot. I want to set my primary ethernet as 10G.

Even when I proceed I run into this problem: https://forums.xilinx.com/t5/Evaluation-Boards/Petalinux-2018-3-runs-into-error-after-adding-10G-ethernet/td-p/957827

10G design

No 10G ethernet. Only 1G ethernet

Petalinux-config

This looks fine. In the resulting device tree, is the alias setup correctly?

Open system-top.dts, and the ethernet0 should be set to your axi ethernet node (you can see this in the pl.dtsi)

Ill respond to other thread seperately.

[astrome]

Looks like alias is set properly.

System-top.dts:

/dts-v1/;
#include "pl.dtsi"
/ {
chosen {
bootargs = "earlycon";
stdout-path = "serial0:115200n8";
};
aliases {
ethernet0 = &axi_ethernet;
ethernet1 = &xxv_ethernet_0;
i2c0 = &iic_main;
serial0 = &rs232_uart;
spi0 = &axi_qspi;
};
memory@80000000 {
device_type = "memory";
reg = <0x80000000 0x80000000>;

[stephenm]

you can update the alias if you want to make this primary in the system-user.dtsi:

&aliases {

ethernet0 = &xxv_ethernet_0;
ethernet1 = &axi_ethernet;
};

[astrome · Accepted solution]

10G is supported by petalinux, but it does not appear in the primary ethernet section of Petalinux-config. One has to enable all the necessary drivers and assign MAC addresses manually. One can see the drivers loading in the kernel log.

[jamellyf]

How can I choose on of these options with petalinux-config?

[stephenm]

Can you try petalinux-config -> Subsystem AUTO Hardware Settings -> Ethernet Settings -> Primary Ethernet

If using xxvethernet, you should see this here

[jamellyf]

I'm using 10G ethernet subsystem(PG157)
