The character device interface, on the other hand, creates new requests, adds them to the request-list of the block device, and waits for their completion. Pipelined operation mode is now supported on both reads and writes. The block device major and minor numbers are determined from the tape's relative position in the ide interfaces, as explained in ide.c. The character device interface consists of the following devices: ht0 major 37, minor 0 first IDE tape, rewind on close. ht1 major 37, minor 1 second IDE tape, rewind on close. ... nht0 major 37, minor 128 first IDE tape, no rewind on close. nht1 major 37, minor 129 second IDE tape, no rewind on close. ... Run /dev/MAKEDEV to create the above entries. The general magnetic tape commands compatible interface, as defined by include/linux/mtio.h, is accessible through the character device. General ide driver configuration options, such as the interrupt-unmask flag, can be configured by issuing an ioctl to the block device interface, as any other ide device. Our own ide-tape ioctl's can be issued to either the block device or the character device interface. Maximal throughput with minimal bus load will usually be achieved in the following scenario: 1. ide-tape is operating in the pipelined operation mode. 2.
