66AK2E05: 66AK2E05: How to Configure gbe interfaces as switch.

Konstantinos,

Rajarajan is working on your query.

He will give his suggestion as early as possible.

Thanks for your patience.

Regards

Shankari G

Hi Rajarajan,

I followed your recommendations and now all "CONFIG_TI_CPSW_..." are indeed added.

I tried: zcat /proc/config.gz | grep CPSW

and got:

CONFIG_TI_CPSW_PHY_SEL=y
CONFIG_TI_CPSW_ALE=y
CONFIG_TI_CPSW=y

Unfortunately ethtool still does not work.

Is there something i am missing ?? 

Thank you,

Konstantinos Ilias.

Hi Konstantinos,

Will check with my EVM and provide an update.

Thanks

Rajarajan U

Mr Rajarajan, do you have any update ? 

Hi Konstantinos,

I am held up with another task, I will resume to looking into this after 2-3 days.

Thanks,

Rajarajan U

Mr Rajarajan,

I also face an issue with the ioctl part of the configuration.

I managed to compile it and make it work, but i get Operation not supported whenever i try ioctl(sockfd, SIOCSWITCHCONFIG, &ifr); command 

Do you have any comments about this also, do you need further information ? 

I added the code below.

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <string.h>
#include <sys/types.h>
#include <sys/socket.h>
#include <arpa/inet.h>
#include <netinet/in.h>
#include <netdb.h>
#include <sys/ioctl.h>
#include <net/if.h>

#include <stdio.h>
#include <asm/sockios.h>
#include <net/if.h>
#include <string.h>
#include <linux/sockios.h>
#include <errno.h>

#include "net_switch_config.h"



int main(void)
{
    struct net_switch_config cmd_struct;
    struct ifreq ifr;
    int sockfd;
    int16_t retVal =-100;

    strncpy(ifr.ifr_name, "eth0", IFNAMSIZ);

    ifr.ifr_data = (char*)&cmd_struct;

    if ((sockfd = socket(AF_INET, SOCK_DGRAM, 0)) < 0) {
        printf("[IDE:]Can't open the socket\n");
        return -1;
    }
    else{
        printf("[IDE:]socket openeed sucesfully \n");
    }

    memset(&cmd_struct, 0, sizeof(struct net_switch_config));

    //...//initialise cmd_struct with switch commands

    cmd_struct.cmd = CONFIG_SWITCH_GET_PORT_CONFIG;

    ifr.ifr_data = (char*)&cmd_struct;

    retVal = ioctl(sockfd, SIOCSWITCHCONFIG, &ifr);

    if (retVal < 0) {
        printf("Command CONFIG_SWITCH_GET_PORT_CONFIG port =0 failed\n");

        perror("retVal");

        close(sockfd);

        return -1;
    }
    else{
        printf("Command CONFIG_SWITCH_GET_PORT_CONFIG port =0 Succeeded\n");
    }

    printf("command success\n");
    close(sockfd);
    return 0;
}

i am looking forward for your reply.

Hi Konstantinos,

I will look into the "ioctl" operation and get back to you.

Thanks,

Rajarajan U

Mr Rajarajan,

Thanks for your reply, i already did a test backporting some files from kernel 5.10 to 4.19 but it did not fix my issue, i will try with kernel 5.10 and give you a feedback. 

My biggest issue right now is about the device tree. 

I did not find any examples for configuring netcp as switch using device tree.

Is my netcp device tree correct? 

Why do i get

cpsw: 2620110.netcp invalid resource

cpsw: probe of 2620110.netcp failed with error -22

Thank you.

Konstantinos

Hi Konstantinos,

Will analyze your Device tree and post my response.

Thanks,

Rajarajan U

Hi Konstantinos,

I believe you have been working on Linux, There is a CPPI working example project developed on the TI-RTOS kernel, which uses the same configuration as the CPSW driver.

To verify the configuration kindly look into the code for reference.

CPSW configuration is located in the file: ti\pdk_k2e_4_0_16\packages\ti\drv\cppi\device\k2e\src

TI-RTOS SDK Link

https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1040858/faq-66ak2e05-how-to-generate-the-ccs-pdk-examples-for-k2e

I am working on the Netcp driver configuration. I will provide a response ASAP.

Thanks

Hi Konstantinos,

I have gone through CPSW switch documentation,

https://software-dl.ti.com/processor-sdk-linux/esd/docs/06_03_00_106/linux/Foundational_Components/Kernel/Kernel_Drivers/Network/CPSW.html

Kindly look into it.

Thanks,

Rajarajan U

Mr Rajarajan,

I am aware of this document, this is the first document that i started on. 

On the other hand on the tisdk linux kerneI, i found  “./Documentation/devicetree/bindings/net/keystone-netcp.txt” that describes the port binding procedure.

I tried to configure the device tree following those instructions (changing the registers for k2e), but I did not manage to achieve port binding in the evaluation board.

My goal is to configure all 8 ports of k2e netcp as an unmanaged switch.

And my questions are:

• How should I modify the device tree?  
• Do I need any further configuration (except of the device tree)?
• Do I need ethtool or some other tool in user space? 

Could you provide me with some help about it ?

Yours sincerely,

Konstantinos.

Hi Konstantinos,

I know little about the device tree but had intimated the kernel experts.

Kindly look into the reference device tree for the netcp.

https://kernel.googlesource.com/pub/scm/linux/kernel/git/next/linux-next/+/refs/heads/akpm-base/Documentation/devicetree/bindings/net/keystone-netcp.txt

Thanks,

Rajarajan U

Hi Rajaran,

I am the FAE for Konstantinos. I was wondering if you were able to ask around in the team if we have any knowledge regarding the device tree?

Kind regards,

Daniel

Hi all, 

I managed to make it work almost as a normal switch.

The Steps:

1) In the menuconfig i added the CPSW related and 802... modules.

2) The device tree i used is like the one in

documentation “./Documentation/devicetree/bindings/net/keystone-netcp.txt” .

3) Then i run the following commands.

1. echo "port0_unicast_flood=1" > /sys/class/net/eth0/device/ale_control
2. echo "bypass=0" > /sys/class/net/eth0/device/ale_control
3. echo "no_port_vlan=1" > /sys/class/net/eth0/device/ale_control
   

The current situation:

+-------------------------------+			|-----------------------|
|	K2e EVM                     |  			|Server					|

+-------------------------------+			|-----------------------|

• Server(10.10.10.191) Pings Laptop(10.10.10.200) and Laptop Pings Server
• Server(10.10.10.191) Pings K2eEVM(10.10.10.171) and K2eEVM pings Server
• K2eEVM(10.10.10.171) can NOT ping Laptop(10.10.10.200) and Laptop can NOT ping K2eEVM  

How should i resolve this issue ??

Do i need to echo something more into ale_control ?

If you need any further information please let me know.

Yours sincerely,

Konstantinos
