TDA4VM: Whether CPSW9g virtual MAC in Linux support Multicast frame send/receive ?

hutian

Part Number: TDA4VM

HI experts,

Whether CPSW9g virtual MAC driver in linux (A72 core) support Multicast frame send/receive ? If not , how to modify the j721e-cpsw-virt-mac.c in linux to make it support?

In the Linux SDK of TDA4, i have noticed that "CPSW2G" describe the Multicast Add/Delete, but CPSW9G virtual doesn't.

Thanks,

Hutian

Hutian,

The multicast add/delete is supported through the Ethernet Firmware, so needs to be set up with IPC calls (rpmsg). Currently the Linux virtual driver supports a subset of direct commands, as outlined on http://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/latest/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/Network/J7_CPSW9g_virt_mac.html :

rpmsg_kdrv_switch driver

The rpmsg_kdrv_switch driver (drivers/rpmsg-kdrv/rpmsg_kdrv_switch.c) does not perform any functions by iteslf, except checking for the supported EthSwitch FW version. It’s intended to provide the RPMSG-KDRV rpmsg_remotedev API interface to be used by the j721e-cpsw-virt-mac driver. Features controlled by the RPMSG-KDRV rpmsgi_remotedev API include: - DMA resources allocation: TX UDMA channel and RX Flow - MAC addresses assignment - ARP helper for ARP requests processing from remote Net Hosts - dbg: IPC ping - dbg: CPSW0 register access - dbg: statistic print request on R5F console (ioctl)

j721e-cpsw-virt-mac driver

The j721e-cpsw-virt-mac driver (drivers/net/ethernet/ti/j721e-cpsw-virt-mac.c) follows the standard Linux network interface architecture and supports the following features:

- Network device up/down
- Automatic (or manual) MAC address assignment
- IP address assignment
- Basic Ethertool functions
- RX/TX csum offload (if enabled by EthSwitch FW)

So setting up multicast from Linux is not currently supported.

Best regards,

Dave

Hi Dave,

I have added the Mcast by CpswApp_setAleMulticastEntry(&MCastAddr[0U],0U, 9U,CPSW_ALE_ALL_PORTS_MASK) setting at ETHFW. The CPSW9G has transferred the MCast frame from external port4 to host post0, but i can’t using tcpdump (eth1) to dump anything else frame.The ping function is OK but Mcast frame failed.

Currently i can use eth1 to send the Mcast frame but can’t receive, although the inter-switch has transferred the Mcast frame to host port successfully. Could you help me to figure out it?
