摘要： An I/O adapter is installed in a slot in a computer system. Online deletion of the I/O adapter is achieved by a three step process, in which a device driver that controls the adapter first attempts to quiesce the adapter, the slot is then powered off, if it is possible to do so, and finally, if the quiesce operation was successful or the slot is powered off, the driver completes the delete operation by unmapping buffers and cleaning up datastructures associated with the device driver.
