Struct HardwareConfigFaultConfig 

pub struct HardwareConfigFaultConfig {
    pub vendor_id: Option<u16>,
    pub device_id: Option<u16>,
}

A fault configuration for overriding the device’s hardware configuration (i.e. the values reported in PCI configuration space).

When a field is Some, its value replaces the corresponding field reported by the NVMe fault controller’s PCI hardware IDs. When None, the real hardware ID value is used unchanged. Unlike most other faults in this module, hardware config faults are applied at device construction time and are therefore not gated by the fault_active flag.

Example

Override the Vendor ID and Device ID reported in PCI config space.

use mesh::CellUpdater;
use nvme_resources::fault::FaultConfiguration;
use nvme_resources::fault::HardwareConfigFaultConfig;

pub fn hardware_config_fault() -> FaultConfiguration {
    let mut fault_start_updater = CellUpdater::new(false);
    FaultConfiguration::new(fault_start_updater.cell())
        .with_hardware_config_fault(
            HardwareConfigFaultConfig::new()
                .with_vendor_id(0x1414)
                .with_device_id(0xc03e),
        )
}

Fields

vendor_id: Option<u16>

Override for the device’s PCI Vendor ID. When None, the real Vendor ID is used.

device_id: Option<u16>

Override for the device’s PCI Device ID. When None, the real Device ID is used.

Implementations

impl HardwareConfigFaultConfig

pub fn new() -> Self

Create a new no-op hardware config fault configuration. All fields default to None, meaning the real hardware values are used.

pub fn with_vendor_id(self, vendor_id: u16) -> Self

Override the PCI Vendor ID reported by the device.

pub fn with_device_id(self, device_id: u16) -> Self

Override the PCI Device ID reported by the device.
