Abstract
A method of operating a storage device controller which controls a storage device includes receiving a debugging data request command through a peripheral component interconnect express (PCIe) interface of the storage device controller from outside of the storage device controller, and storing debugging data in a register included in the PCIe interface.
Claims20
A method of operating a storage device controller which controls a storage device, the method comprising:
- receiving a debugging data request command through a peripheral component interconnect express (PCIe) interface of the storage device controller from outside of the storage device controller;
- and
- storing debugging data in a register included in the PCIe interface.
A method of operating a storage device controller which controls a storage device, the method comprising:
- receiving, from a host, a debugging data request command through a peripheral component interconnect express (PCIe) interface of the storage device controller;
- and
- storing debugging data in a host buffer memory included in the host.
A method of operating a host system which includes a host and a storage device, the method comprising:
- starting, at the host, a debugging operation;
- stopping, at the host, an operation of a first device driver and running a second device driver;
- transmitting, from the host, a debugging data request command generated at the second device driver to the storage device;
- and
- transmitting, from the storage device, debugging data to the host through a peripheral component interconnect express (PCIe) interface of the storage device.
