DOCA 功能打印工具
本文档提供关于 DOCA 功能打印工具用法的说明。
此工具用于打印所有可用的 DOCA 库和设备。对于每个 DOCA 设备，此工具打印其代表设备以及它在每个 DOCA 库中支持的功能。
DOCA 2.6.0 及更高版本。
此工具可以在主机或 Arm 端执行。
此工具支持以下功能
DOCA 设备列表 – 打印每个可用 DOCA 设备的 PCIe 设备及其功能
DOCA 代表设备列表 – 对于每个 DOCA 设备，打印每个可用 DOCA 代表设备的 PCIe 设备及其功能
DOCA 库列表 – 打印运行 OS 支持的可用 DOCA 库及其对特定 OS 的可用性
DOCA 库功能 – 对于每个 DOCA 设备，打印其在每个 DOCA 库中支持的功能
要打印所有可用的 DOCA 设备及其功能，请运行
/opt/mellanox/doca/tools/doca_caps --list-devs
信息可以使用
--pci-addr标志打印特定 DOCA 设备的功能。示例输出
/opt/mellanox/doca/tools/doca_caps --list-devs PCI: 0000:03:00.0 ibdev_name mlx5_0 iface_name p0 mac_addr 94:6d:ae:5c:9e:04 ipv4_addr 0.0.0.0 ipv6_addr fe80:0000:0000:0000:966d:aeff:fe5c:9e04 gid_table_size 255 GID[0] fe80:0000:0000:0000:966d:aeff:fe5c:9e04 PCI: 0000:03:00.1 ibdev_name mlx5_1 iface_name p1 mac_addr 94:6d:ae:5c:9e:05 ipv4_addr 0.0.0.0 ipv6_addr fe80:0000:0000:0000:966d:aeff:fe5c:9e05 gid_table_size 255 GID[0] fe80:0000:0000:0000:966d:aeff:fe5c:9e05 PCI: 0000:03:00.0 ibdev_name mlx5_2 iface_name enp3s0f0s0 mac_addr 02:c6:d0:fd:56:d7 ipv4_addr 0.0.0.0 ipv6_addr fe80:0000:0000:0000:00c6:d0ff:fefd:56d7 gid_table_size 255 GID[0] fe80:0000:0000:0000:00c6:d0ff:fefd:56d7 PCI: 0000:03:00.1 ibdev_name mlx5_3 iface_name enp3s0f1s0 mac_addr 02:b6:4f:a9:fa:9a ipv4_addr 0.0.0.0 ipv6_addr fe80:0000:0000:0000:00b6:4fff:fea9:fa9a gid_table_size 255 GID[0] fe80:0000:0000:0000:00b6:4fff:fea9:fa9a
要打印所有可用的 DOCA 代表设备及其功能，请运行
/opt/mellanox/doca/tools/doca_caps --list-rep-devs
信息此命令仅在 Arm 端可用。
信息可以使用
--pci-addr标志打印特定 DOCA 设备的代表列表。示例输出
/opt/mellanox/doca/tools/doca_caps --list-rep-devs PCI: 0000:03:00.0 representor-PCI: 0000:3b:00.0 pci_func_type PF hotplug no vuid MT2308XZ0BN0MLNXS0D0F0 representor-PCI: 0000:3b:00.0 pci_func_type SF hotplug no vuid MT2308XZ0BN0ECMLNXS0D0F0SF32800 PCI: 0000:03:00.1 representor-PCI: 0000:3b:00.1 pci_func_type PF hotplug no vuid MT2308XZ0BN0MLNXS0D0F1 representor-PCI: 0000:3b:00.1 pci_func_type SF hotplug no vuid MT2308XZ0BN0ECMLNXS0D0F1SF32800 PCI: 0000:03:00.0 PCI: 0000:03:00.1
要打印 OS 支持的所有 DOCA 库及其可用性状态，请运行
/opt/mellanox/doca/tools/doca_caps --list-libs
信息不同的 OS 可能支持不同的 DOCA 库。
示例输出
/opt/mellanox/doca/tools/doca_caps --list-libs common installed aes_gcm installed apsh installed argp installed cc installed comm_channel installed compress installed dma installed dpa installed dpdk_bridge installed erasure_coding installed eth installed ipsec installed flow installed flow_ct installed pcc installed rdma installed sha installed telemetry installed
要打印每个 DOCA 设备的所有可用库（具有功能）的所有功能，请运行
/opt/mellanox/doca/tools/doca_caps
信息可以使用
--pci-addr标志打印一个特定 DOCA 设备的功能。信息可以使用
--lib标志打印一个特定 DOCA 库的功能。示例输出
