Devlink configuration parameters ================================ Following is the list of configuration parameters via devlink interface. Each parameter can be generic or driver specific and are device level parameters. Note that the driver-specific files should contain the generic params they support to, with supported config modes. Each parameter can be set in different configuration modes: runtime - set while driver is running, no reset required. driverinit - applied while driver initializes, requires restart driver by devlink reload command. permanent - written to device's non-volatile memory, hard reset required. Following is the list of parameters: ==================================== enable_sriov [DEVICE, GENERIC] Enable Single Root I/O Virtualisation (SRIOV) in the device. Type: Boolean ignore_ari [DEVICE, GENERIC] Ignore Alternative Routing-ID Interpretation (ARI) capability. If enabled, adapter will ignore ARI capability even when platforms has the support enabled and creates same number of partitions when platform does not support ARI. Type: Boolean msix_vec_per_pf_max [DEVICE, GENERIC] Provides the maximum number of MSIX interrupts that a device can create. Value is same across all physical functions (PFs) in the device. Type: u32 msix_vec_per_pf_min [DEVICE, GENERIC] Provides the minimum number of MSIX interrupts required for the device initialization. Value is same across all physical functions (PFs) in the device. Type: u32 fw_load_policy [DEVICE, GENERIC] Controls the device's firmware loading policy. Valid values: * DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_DRIVER (0) Load firmware version preferred by the driver. * DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_FLASH (1) Load firmware currently stored in flash. * DEVLINK_PARAM_FW_LOAD_POLICY_VALUE_DISK (2) Load firmware currently available on host's disk. Type: u8 reset_dev_on_drv_probe [DEVICE, GENERIC] Controls the device's reset policy on driver probe. Valid values: * DEVLINK_PARAM_RESET_DEV_ON_DRV_PROBE_VALUE_UNKNOWN (0) Unknown or invalid value. * DEVLINK_PARAM_RESET_DEV_ON_DRV_PROBE_VALUE_ALWAYS (1) Always reset device on driver probe. * DEVLINK_PARAM_RESET_DEV_ON_DRV_PROBE_VALUE_NEVER (2) Never reset device on driver probe. * DEVLINK_PARAM_RESET_DEV_ON_DRV_PROBE_VALUE_DISK (3) Reset only if device firmware can be found in the filesystem. Type: u8 |
