sysfs interface

---------------

The pktcdvd module (packet writing driver) creates the following files in the

sysfs: (<devid> is in the format major:minor)



What:		/sys/class/pktcdvd/add

What:		/sys/class/pktcdvd/remove

What:		/sys/class/pktcdvd/device_map

Date:		Oct. 2006

KernelVersion:	2.6.20

Contact:	Thomas Maier <balagi@justmail.de>

Description:



		==========	==============================================

		add		(WO) Write a block device id (major:minor) to

				create a new pktcdvd device and map it to the

				block device.



		remove		(WO) Write the pktcdvd device id (major:minor)

				to remove the pktcdvd device.



		device_map	(RO) Shows the device mapping in format:

				pktcdvd[0-7] <pktdevid> <blkdevid>

		==========	==============================================





What:		/sys/class/pktcdvd/pktcdvd[0-7]/dev

What:		/sys/class/pktcdvd/pktcdvd[0-7]/uevent

Date:		Oct. 2006

KernelVersion:	2.6.20

Contact:	Thomas Maier <balagi@justmail.de>

Description:

		dev:	(RO) Device id



		uevent:	(WO) To send a uevent





What:		/sys/class/pktcdvd/pktcdvd[0-7]/stat/packets_started

What:		/sys/class/pktcdvd/pktcdvd[0-7]/stat/packets_finished

What:		/sys/class/pktcdvd/pktcdvd[0-7]/stat/kb_written

What:		/sys/class/pktcdvd/pktcdvd[0-7]/stat/kb_read

What:		/sys/class/pktcdvd/pktcdvd[0-7]/stat/kb_read_gather

What:		/sys/class/pktcdvd/pktcdvd[0-7]/stat/reset

Date:		Oct. 2006

KernelVersion:	2.6.20

Contact:	Thomas Maier <balagi@justmail.de>

Description:

		packets_started:	(RO) Number of started packets.



		packets_finished:	(RO) Number of finished packets.



		kb_written:		(RO) kBytes written.



		kb_read:		(RO) kBytes read.



		kb_read_gather:		(RO) kBytes read to fill write packets.



		reset:			(WO) Write any value to it to reset

					pktcdvd device statistic values, like

					bytes read/written.

What:		/sys/class/pktcdvd/pktcdvd[0-7]/write_queue/congestion_off

What:		/sys/class/pktcdvd/pktcdvd[0-7]/write_queue/congestion_on

Date:		Oct. 2006

KernelVersion:	2.6.20

Contact:	Thomas Maier <balagi@justmail.de>

Description:

		==============	================================================

		size		(RO) Contains the size of the bio write queue.



		congestion_off	(RW) If bio write queue size is below this mark,

				accept new bio requests from the block layer.



		congestion_on	(RW) If bio write queue size is higher as this

				mark, do no longer accept bio write requests

				from the block layer and wait till the pktcdvd

				device has processed enough bio's so that bio

				write queue size is below congestion off mark.

				A value of <= 0 disables congestion control.

		==============	================================================





Example:

--------

To use the pktcdvd sysfs interface directly, you can do::



    # create a new pktcdvd device mapped to /dev/hdc

    echo "22:0" >/sys/class/pktcdvd/add

    cat /sys/class/pktcdvd/device_map

    # assuming device pktcdvd0 was created, look at stat's

    cat /sys/class/pktcdvd/pktcdvd0/stat/kb_written

    # print the device id of the mapped block device

    fgrep pktcdvd0 /sys/class/pktcdvd/device_map

    # remove device, using pktcdvd0 device id   253:0

    echo "253:0" >/sys/class/pktcdvd/remove
