A PCIe hot reset is a feature that allows a device to be reset while the system is still running without affecting other devices on the PCIe bus. This is useful in situations where a device may have encountered an error or has stopped responding, and a reset is needed to restore its functionality.
During a PCIe hot reset, the device is temporarily removed from the bus, and the configuration registers are reset to their default values. The device is then re-enumerated and reinitialized by the system, allowing it to resume normal operation.
PCIe hot reset is triggered by software or firmware, and it requires support from both the device and the system. It is a useful feature for maintaining system availability and avoiding downtime due to device failures.
