Hi, Santosh, Indeed the following patch from Ferruh removed the rte_pci_device from the rte_eth_dev_info object, and instead added an object of rte_device:
http://patchwork.dpdk.org/patch/37654/ However, I see that the date that this patch was applied to dpdk-next-net/master is 4/10/2018. Are you absolutely sure the patch is applied in dpdk-17.11? I checked in 17.11.3 (stable), and I do see struct rte_pci_device *pci_dev in struct rte_eth_dev_info. It seems to me that the following snippet of code from DPDK-18.05 can do what you want: dpdk-18.05/examples/ethtool/lib/rte_ethtool.c: rte_ethtool_get_drvinfo() { .... const struct rte_pci_device *pci_dev; ... if (dev_info.device) bus = rte_bus_find_by_device(dev_info.device); if (bus && !strcmp(bus->name, "pci")) { pci_dev = RTE_DEV_TO_PCI(dev_info.device); snprintf(drvinfo->bus_info, sizeof(drvinfo->bus_info), "%04x:%02x:%02x.%x", pci_dev->addr.domain, pci_dev->addr.bus, pci_dev->addr.devid, pci_dev->addr.function); } else { pci_dev->addr.devid, pci_dev->addr.function); Regards, Rami Rosen Intel -----Original Message----- From: dev [mailto:dev-boun...@dpdk.org] On Behalf Of santhosh K.S Sent: Tuesday, July 24, 2018 13:10 To: dev@dpdk.org Subject: [dpdk-dev] Accessing "device_id" from "rte_pci_device" Hi, I'm currently trying to migrate our old DPDK 16.11 version to 17.11 release. For this activity, I'm able to build the 17.11 DPDK successfully. When I try to use the new libs, I noticed that few of the struct members which we are using in our code is moved to some other struct. In the 16.11 version we were using "*rte_eth_dev_info_get*" API to get the device_id information using "*rte_pci_device*" struct which was initialized inside the rte_eth_dev_info_get() API. But now in 17.11 "*rte_pci_device" pointer * is not initialized inside the ret_eth_dev_inf_get() API, that is because rte_pic_device is no longer a member of the struct "*rte_eth_dev*". Hence I'm not able to retrive the device_id from "*pci_dev->id.device_id*" Can anyone please point me to an example code which illustrates the same? I've already googled and got this link <http://doc.dpdk.org/api-17.11/examples_2ethtool_2lib_2rte_ethtool_8c-example.html#a5>. Which unfortunately doesn't show how to extract the *device_id*. Best Regards, Santy
