| Ticket Name: Add source & destination in IP & ports & compare with LUT in NetCP Packet Accelerator | |
| Query Text: | |
| Other Parts Discussed in Thread: AM5K2E04 Hi, We started working Linux Network CoProcessor NetCP Yocto BSP [sdk-06.03.00.106] works on AM5k2E04 board, get driver source available in Kernel 4.4.19. We need to capture Ethernet packets from FTP connection, Add source IP & destination IP, source port & destination port From Packet accelerator driver [drivers/net/ethernet/ti/netcp_pa.c] We able to see pa_add_mac_rule API to compare source & destination mac. We referred Packet accelerator user guide to adding entries & PA API's for TI PDK source packages. Here we want Linux drivers API's for adding IP, Mac, Port & LUT, Comparing with LUT for header extractions. Anyone please provide API for creating Lookup table & add source & destination IP & ports in Linux Kernel PA drivers for NetCP. Regards, Santhana Kumar S | |
| Responses: | |
| Hi, Santhana, You may want to develop your own. These API's will be feature requests to TI PLSDK. I'll keep the thread open to see if there is any contribution from cummunity. Rex | |
| Thanks for your response. Can you please help to let me know from your community. | |
| Hi Rex, Any updates for this thread? | |
| Hi, Santhana, The community I meant is the contribution from non-TI member in the forum. .Any specific kernel APIs will be feature request. It will need to go through business review before it can be implemented. Rex | |
| Hi Rex, I understand for this thread, you are telling non TI member will be support for this thread. So anyone from TI Community member worked in NetCP, Packet Accelerator add this thread for them. still doubt in using netcp. | |
| Hi, Any updates about this thread. Please support this thread for giving me brief explanation of Packet Accelerator driver code to use in NetCP linux BSP. Regards, SanthanaKumarS | |
| Hi, Santhana, Please refer to PA User's Guide: https://www.ti.com/lit/ug/spruhz2/spruhz2.pdf Rex software-dl.ti.com/.../NetCP.html | |

| Hi, We are using Yocto BSP for porting NetCP in AM5K2E04 board Can you please detailed explanation of Packet Accelerator code for packages/ti/drv/pa & drivers/net/ethernet/ti/netcp_pa.c Referred PA user guide, For packages PA consists of Pa_addLUT, Pa_addMac, Pa_addIP, Pa_addPort & Firmware API in ti/drv/pa/fw Source Code : NetCP PA : netcp-pa-fw/1_2020.4.16-r0.4/git/ti/drv/pa/ NetCP PA Linux: drivers/net/ethernet/ti/netcp_pa.c We need to use capture Ethernet packets from FTP Connection to adding LUT, MAC, IP & port & compare in to LUT table for adding queues in Yocto BSP Linux side Rex, Please guide me to help on this | |
| Hi, Santhana, Theoretically, Yocto is just a way to build. It shouldn't be any difference in terms of kernel source code. I don't see the netcp_pa.c in PLSDK kernel source code. I'll need to clone it and see what's in that repository. I don't know the answer on top of my head. Rex | |
| Hi, Yocto source is build for Kernel & u-boot images. Here I attached PA driver file. Thanks for your daily update, You provided NetCP & PA user guide, We refer some LLD API's provide for CCS StandAlone Application to interface with NetCP PA. Note: We need Linux side not for CCS StandAlone Application. We need to capture Ethernet packets from FTP connection, Below we are given points to test in Linux AM5k2e04 Keystone SOC board. 1. Enable Packet Accelerator to send & receive FTP data 2. Disable Packet Accelerator to send & receive FTP data In both the cases, We should receive FTP packets from NetCP & Can you please connect mail to Yocto Linux BSP side for worked in NetCP PA. Then we have a good clarity to use NetCP PA in Linux side. Regards, SanthanaKumarS | |
| Hi Rex, We configured Netcp interfaces in K2E EVM board, & we able to run packet accelerator application to run paMCExample.out from given by Packet accelerator provided. Here we attached Log to testing my multicore application to test adding Ip, MAC & port between source & destination packets. For our test results, Application is passing but i can't able to see my packets in Wireshark application from PC. Please check my logs & code to give me solutions for this. Can you please tell me the changes to adding MAC, IP & ports & packet buffer in source code to please mention which source & destination MAC, IP & ports to given in source code Add_MACAddress - paEthInfo_t ethInfo = { { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 }, /* Src mac = dont care */ { 0x10, 0x11, 0x12, 0x13, 0x14, 0x15 }, /* Dest MAC */ 0, /* vlan = dont care */ 0x0800, /* ether type = IPv4 */ 0, /* MPLS tag = dont care */ 0 /* Input EMAC port = dont care */ Add_IP - paIpInfo_t ipInfo = { { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }, /* IP source = dont care */ { 0xc0, 0xa8, 0x01, 0xa, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 },* IP dest */ Add_Port - int16_t ports = {0x5678}; paRouteInfo_t routeInfo = { pa_DEST_HOST, /* Route a match to the host */ 0, /* Flow ID 0 */ 0, /* Destination queue */ -1, /* Multi route disabled */ 0xaaaaaaaa, /* SwInfo 0 */ 0, /* SwInfo 1 is dont care */ 0, /* customType = pa_CUSTOM_TYPE_NONE */ \ 0, /* customIndex: not used */ \ 0, /* pkyType: for SRIO only */ \ NULL /* No commands */ }; SendPacket() - uint8_t pktMatchBuf[PACKET_SIZE] = { 0x10, 0x11, 0x12, 0x13, 0x14, 0x15, /* Dest MAC */ 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, /* Src MAC */ 0x08, 0x00, /* Ethertype = IPv4 */ 0x45, 0x00, 0x00, 0x6c, /* IP version, services, total length */ 0x00, 0x00, 0x00, 0x00, /* IP ID, flags, fragment offset */ 0x05, 0x11, 0x32, 0x26, /* IP ttl, protocol (UDP), header checksum */ 0xc0, 0xa8, 0x01, 0x01, /* Source IP address */ 0xc0, 0xa8, 0x01, 0x0a, /* Destination IP address */ 0x12, 0x34, 0x56, 0x78, /* UDP source port, dest port */ 0x00, 0x58, 0x1d, 0x18, /* UDP len, UDP checksum */ 0x32, 0x33, 0x34, 0x35, 0x36, 0x37, 0x38, 0x39, /* 80 bytes of payload data */ 0x3a, 0x3b, 0x3c, 0x3d, 0x3e, 0x3f, 0x40, 0x41, 0x42, 0x43, 0x44, 0x45, 0x46, 0x47, 0x48, 0x49, 0x4a, 0x4b, 0x4c, 0x4d, 0x4e, 0x4f, 0x50, 0x51, 0x52, 0x53, 0x54, 0x55, 0x56, 0x57, 0x58, 0x59, 0x5a, 0x5b, 0x5c, 0x5d, 0x5e, 0x5f, 0x60, 0x61, 0x62, 0x63, 0x64, 0x65, 0x66, 0x67, 0x68, 0x69, 0x6a, 0x6b, 0x6c, 0x6d, 0x6e, 0x6f, 0x70, 0x71, 0x72, 0x73, 0x74, 0x75, 0x76, 0x77, 0x78, 0x79, 0x7a, 0x7b, 0x7c, 0x7d, 0x7e, 0x7f, 0x80, 0x81 }; Command line testing ================================== # rmServer.out /usr/bin/device/k2e/global-resource-list.dtb /usr/bin/device/k2e/policy_dsp_arm.dtb # paMCExample.out root@AM5K2E04:~# paMCExample_k2e.out No command line given.

| Hi, Santhana, I am not familiar with paMCExample and it doesn't ring any bell. Could you provide more info about it? Rex | |
| Hi Rex, We configured NetCP interfaces & tested Ethernet its working fine. In K2E evm board, there is packet accelerator & Security accelerator components. So we need to use packet accelerator to add Ip, Mac & ports in Lookup table to comparing mac, ip & ports to do some experiment. We are using PA LLD api's Add_MACAddress, Add_IPAddress & Add_Port for adding MAC, IP & ports in Lookup table. Here we using pa/example/multicoreExample/src/pa_mgmt.c , for sent/receive packet to handling packet from source to destination. Mainly we need to use Packet accelerator to handling packets from evm board. We are looking for pa example codes to handling packets from board Ethernet to other Ethernet connection | |
| Hi, Santhana, I'll need to ask the expert who is familiar with PDK PA example to take a look. Are you trying to implement NAT in Linux? Rex | |
| Hi Rex, Thanks for your attention. We need to add our ip,port & mac using PA LLD api's & sending packets from evm board to specific added MAC in PA example codes. We tried to added destination MAC, IP & ports but packets not receiving, & not able to see my IP address Wireshark application . Here we added IP, MAC & ports in PA LLD api's & attched logs. Please talk to your PA LLD experts & let me know the solutions for this.
