Intro
=====
This file describes some issues involved when using the "ftape"
floppy tape device driver that comes with the Linux kernel.
ftape has a home page at
http://ftape.dot-heine.de/
which contains further information about ftape. Please cross check
this WWW address against the address given (if any) in the MAINTAINERS
file located in the top level directory of the Linux kernel source
tree.
NOTE: This is an unmaintained set of drivers, and it is not guaranteed to work.
If you are interested in taking over maintenance, contact Claus-Justus Heine
<ch@dot-heine.de>, the former maintainer.

A minus 1. Ftape documentation
==============================
Unluckily, the ftape-HOWTO is out of date. This really needs to be
changed. Up to date documentation as well as recent development
versions of ftape and useful links to related topics can be found at
the ftape home page at
http://ftape.dot-heine.de/
*******************************************************************************
A. Changes
==========
1. Goal
~~~~
The goal of all that incompatibilities was to give ftape an interface
that resembles the interface provided by SCSI tape drives as close
as possible. Thus any Unix backup program that is known to work
with SCSI tape drives should also work.
The concept of a fixed block size for read/write transfers is
rather unrelated to this SCSI tape compatibility at the file system
interface level. It developed out of a feature of zftape, a
block wise user transparent on-the-fly compression. That compression
support will not be dropped in future releases for compatibility
reasons with previous releases of zftape.
2. I/O Block Size
~~~~~~~~~~~~~~
The block size defaults to 10k which is the default block size of
GNU tar.
The block size can be tuned either during kernel configuration or
at runtime with the MTIOCTOP ioctl using the MTSETBLK operation
(i.e. do "mt -f /dev/qft0" setblk #BLKSZ). A block size of 0
switches to variable block size mode i.e. "mt setblk 0" switches
off the block size restriction. However, this disables zftape's
built in on-the-fly compression which doesn't work with variable
block size mode.
The BLKSZ parameter must be given as a byte count and must be a
multiple of 32k or 0, i.e. use "mt setblk 32768" to switch to a
block size of 32k.
The typical symptom of a block size mismatch is an "invalid
argument" error message.
3. Write Access when not at EOD (End Of Data) or BOT (Begin Of Tape)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
zftape (the file system interface of ftape-3.x) denies write access
to the tape cartridge when it isn't positioned either at BOT or
EOD.
4. Formatting
~~~~~~~~~~
ftape DOES support formatting of floppy tape cartridges. You need the
`ftformat' program that is shipped with the modules version of ftape.
Please get the latest version of ftape from
ftp://sunsite.unc.edu/pub/Linux/kernel/tapes
or from the ftape home page at
http://ftape.dot-heine.de/
`ftformat' is contained in the `./contrib/' subdirectory of that
separate ftape package.
5. Interchanging cartridges with other operating systems
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The internal emulation of Unix tape device file marks has changed
completely. ftape now uses the volume table segment as specified
by the QIC-40/80/3010/3020/113 standards to emulate file marks. As
a consequence there is limited support to interchange cartridges
with other operating systems.
To be more precise: ftape will detect volumes written by other OS's
programs and other OS's programs will detect volumes written by
ftape.
However, it isn't possible to extract the data dumped to the tape
by some MSDOS program with ftape. This exceeds the scope of a
kernel device driver. If you need such functionality, then go ahead
and write a user space utility that is able to do that. ftape already
provides all kernel level support necessary to do that.
*******************************************************************************
B. Debugging Output
================
1. Introduction
~~~~~~~~~~~~
The ftape driver can be very noisy in that is can print lots of
debugging messages to the kernel log files and the system console.
While this is useful for debugging it might be annoying during
normal use and enlarges the size of the driver by several kilobytes.
To reduce the size of the driver you can trim the maximal amount of
debugging information available during kernel configuration. Please
refer to the kernel configuration script and its on-line help
functionality.
The amount of debugging output maps to the "tracing" boot time
option and the "ft_tracing" modules option as follows:
0 bugs
1 + errors (with call-stack dump)
2 + warnings
3 + information
4 + more information
5 + program flow
6 + fdc/dma info
7 + data flow
8 + everything else
2. Tuning the debugging output
~~~~~~~~~~~~~~~~~~~~~~~~~~~
To reduce the amount of debugging output printed to the system
console you can
i) trim the debugging output at run-time with
mt -f /dev/nqft0 setdensity #DBGLVL
where "#DBGLVL" is a number between 0 and 9
ii) trim the debugging output at module load time with
modprobe ftape ft_tracing=#DBGLVL
Of course, this applies only if you have configured ftape to be
compiled as a module.
iii) trim the debugging output during system boot time. Add the
following to the kernel command line:
ftape=#DBGLVL,tracing
Please refer also to the next section if you don't know how to
set boot time parameters.
*******************************************************************************
C. Boot and load time configuration
================================
1. Setting boot time parameters
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Assuming that you use lilo, the LI)nux LO)ader, boot time kernel
parameters can be set by adding a line
append some_kernel_boot_time_parameter
to `/etc/lilo.conf' or at real boot time by typing in the options
at the prompt provided by LILO. I can't give you advice on how to
specify those parameters with other loaders as I don't use them.
For ftape, each "some_kernel_boot_time_parameter" looks like
"ftape=value,option". As an example, the debugging output can be
increased with
ftape=4,tracing
NOTE: the value precedes the option name.
2. Module load time parameters
~~~~~~~~~~~~~~~~~~~~~~~~~~~
Module parameters can be specified either directly when invoking
the program 'modprobe' at the shell prompt:
modprobe ftape ft_tracing=4
or by editing the file `/etc/modprobe.conf' in which case they take
effect each time when the module is loaded with `modprobe' (please
refer to the respective manual pages). Thus, you should add a line
options ftape ft_tracing=4
to `/etc/modprobe.conf` if you intend to increase the debugging
output of the driver.
3. Ftape boot- and load time options
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
i. Controlling the amount of debugging output
DBGLVL has to be replaced by a number between 0 and 8.
module | kernel command line
-----------------------|----------------------
ft_tracing=DBGLVL | ftape=DBGLVL,tracing
ii. Hardware setup
BASE is the base address of your floppy disk controller,
IRQ and DMA give its interrupt and DMA channel, respectively.
BOOL is an integer, "0" means "no"; any other value means
"yes". You don't need to specify anything if connecting your tape
drive to the standard floppy disk controller. All of these
values have reasonable defaults. The defaults can be modified
during kernel configuration, i.e. while running "make config",
"make menuconfig" or "make xconfig" in the top level directory
of the Linux kernel source tree. Please refer also to the on
line documentation provided during that kernel configuration
process.
ft_probe_fc10 is set to a non-zero value if you wish for ftape to
probe for a Colorado FC-10 or FC-20 controller.
ft_mach2 is set to a non-zero value if you wish for ftape to probe
for a Mountain MACH-2 controller.
module | kernel command line
-----------------------|----------------------
ft_fdc_base=BASE | ftape=BASE,ioport
ft_fdc_irq=IRQ | ftape=IRQ,irq
ft_fdc_dma=DMA | ftape=DMA,dma
ft_probe_fc10=BOOL | ftape=BOOL,fc10
ft_mach2=BOOL | ftape=BOOL,mach2
ft_fdc_threshold=THR | ftape=THR,threshold
ft_fdc_rate_limit=RATE | ftape=RATE,datarate
4. Example kernel parameter setting
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To configure ftape to probe for a Colorado FC-10/FC-20 controller
and to increase the amount of debugging output a little bit, add
the following line to `/etc/lilo.conf':
append ftape=1,fc10 ftape=4,tracing
5. Example module parameter setting
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To do the same, but with ftape compiled as a loadable kernel
module, add the following line to `/etc/modprobe.conf':
options ftape ft_probe_fc10=1 ft_tracing=4

If you have a tape drive that is connected to your floppy

Some tape drives (like the Seagate "Tape Store 3200" or the Iomega
"Ditto 3200" or the Exabyte "Eagle TR-3") come with a "high speed"
controller of their own. These drives (and their companion
controllers) are also supported if you say Y here.
If you have a special controller (such as the CMS FC-10, FC-20,
Mountain Mach-II, or any controller that is based on the Intel 82078
FDC like the high speed controllers by Seagate and Exabyte and
Iomega's "Ditto Dash") you must configure it by selecting the
appropriate entries from the "Floppy tape controllers" sub-menu
below and possibly modify the default values for the IRQ and DMA
channel and the IO base in ftape's configuration menu.
If you want to use your floppy tape drive on a PCI-bus based system,
please read the file <file:drivers/char/ftape/README.PCI>.
The ftape kernel driver is also available as a runtime loadable
module. To compile this driver as a module, choose M here: the
module will be called ftape.

config ZFTAPE
tristate "Zftape, the VFS interface"
depends on FTAPE
---help---
Normally, you want to say Y or M. DON'T say N here or you
WON'T BE ABLE TO USE YOUR FLOPPY TAPE DRIVE.
The ftape module itself no longer contains the routines necessary
to interface with the kernel VFS layer (i.e. to actually write data
to and read data from the tape drive). Instead the file system
interface (i.e. the hardware independent part of the driver) has
been moved to a separate module.
To compile this driver as a module, choose M here: the
module will be called zftape.
Regardless of whether you say Y or M here, an additional runtime
loadable module called `zft-compressor' which contains code to
support user transparent on-the-fly compression based on Ross
William's lzrw3 algorithm will be produced. If you have enabled the
kernel module loader (i.e. have said Y to "Kernel module loader
support", above) then `zft-compressor' will be loaded
automatically by zftape when needed.
Despite its name, zftape does NOT use compression by default.
config ZFT_DFLT_BLK_SZ
int "Default block size"
depends on ZFTAPE
default "10240"
---help---
If unsure leave this at its default value, i.e. 10240. Note that
you specify only the default block size here. The block size can be
changed at run time using the MTSETBLK tape operation with the
MTIOCTOP ioctl (i.e. with "mt -f /dev/qft0 setblk #BLKSZ" from the
shell command line).
The probably most striking difference between zftape and previous
versions of ftape is the fact that all data must be written or read
in multiples of a fixed block size. The block size defaults to
10240 which is what GNU tar uses. The values for the block size
should be either 1 or multiples of 1024 up to a maximum value of
63488 (i.e. 62 K). If you specify `1' then zftape's builtin
compression will be disabled.
Reasonable values are `10240' (GNU tar's default block size),
`5120' (afio's default block size), `32768' (default block size some
backup programs assume for SCSI tape drives) or `1' (no restriction
on block size, but disables builtin compression).

help
Please leave this at `3' unless you REALLY know what you are doing.
It is not necessary to change this value. Values below 3 make the
proper use of ftape impossible, values greater than 3 are a waste of
memory. You can change the amount of DMA memory used by ftape at
runtime with "mt -f /dev/qft0 setdrvbuffer #NUMBUFFERS". Each buffer
wastes 32 KB of memory. Please note that this memory cannot be
swapped out.
config FT_PROC_FS
bool "Enable procfs status report (+2kb)"
depends on FTAPE && PROC_FS
---help---
Optional. Saying Y will result in creation of a directory
`/proc/ftape' under the /proc file system. The files can be viewed
with your favorite pager (i.e. use "more /proc/ftape/history" or
"less /proc/ftape/history" or simply "cat /proc/ftape/history"). The
file will contain some status information about the inserted
cartridge, the kernel driver, your tape drive, the floppy disk
controller and the error history for the most recent use of the
kernel driver. Saying Y will enlarge the size of the ftape driver
by approximately 2 KB.
WARNING: When compiling ftape as a module (i.e. saying M to "Floppy
tape drive") it is dangerous to use ftape's /proc file system
interface. Accessing `/proc/ftape' while the module is unloaded will
result in a kernel Oops. This cannot be fixed from inside ftape.

---help---
This option controls the amount of debugging output the ftape driver
is ABLE to produce; it does not increase or diminish the debugging
level itself. If unsure, leave this at its default setting,
i.e. choose "Normal".
Ftape can print lots of debugging messages to the system console
resp. kernel log files. Reducing the amount of possible debugging
output reduces the size of the kernel module by some KB, so it might
be a good idea to use "None" for emergency boot floppies.
If you want to save memory then the following strategy is
recommended: leave this option at its default setting "Normal" until
you know that the driver works as expected, afterwards reconfigure
the kernel, this time specifying "Reduced" or "None" and recompile
and install the kernel as usual. Note that choosing "Excessive"
debugging output does not increase the amount of debugging output
printed to the console but only makes it possible to produce
"Excessive" debugging output.

Only change this setting if you have a special controller. If you
didn't plug any add-on card into your computer system but just
plugged the floppy tape cable into the already existing floppy drive
controller then you don't want to change the default setting,
i.e. choose "Standard".
Choose "MACH-2" if you have a Mountain Mach-2 controller.
Choose "FC-10/FC-20" if you have a Colorado FC-10 or FC-20
controller.
Choose "Alt/82078" if you have another controller that is located at
an IO base address different from the standard floppy drive
controller's base address of `0x3f0', or uses an IRQ (interrupt)
channel different from `6', or a DMA channel different from
`2'. This is necessary for any controller card that is based on
Intel's 82078 FDC such as Seagate's, Exabyte's and Iomega's "high
speed" controllers.
If you choose something other than "Standard" then please make
sure that the settings for the IO base address and the IRQ and DMA
channel in the configuration menus below are correct. Use the manual
of your tape drive to determine the correct settings!
If you are already successfully using your tape drive with another
operating system then you definitely should use the same settings
for the IO base, the IRQ and DMA channel that have proven to work
with that other OS.
Note that this menu lets you specify only the default setting for
the hardware setup. The hardware configuration can be changed at

Set the FIFO threshold of the FDC. If this is higher the DMA
controller may serve the FDC after a higher latency time. If this is
lower, fewer DMA transfers occur leading to less bus contention.
You may try to tune this if ftape annoys you with "reduced data
rate because of excessive overrun errors" messages. However, this
doesn't seem to have too much effect.
If unsure, don't touch the initial value, i.e. leave it at "8".

Some notes for ftape users with PCI motherboards:
=================================================
The problem:
------------
There have been some problem reports from people using PCI-bus based
systems getting overrun errors.
I wasn't able to reproduce these until I ran ftape on a Intel Plato
(Premiere PCI II) motherboard with bios version 1.00.08AX1.
It turned out that if GAT (Guaranteed Access Timing) is enabled (?)
ftape gets a lot of overrun errors.
The problem disappears when disabling GAT in the bios.
Note that Intel removed this setting (permanently disabled) from the
1.00.10AX1 bios !
It looks like that if GAT is enabled there are often large periods
(greater than 120 us !??) on the ISA bus that the DMA controller cannot
service the floppy disk controller.
I cannot imagine this being acceptable in a decent PCI implementation.
Maybe this is a `feature' of the chipset. I can only speculate why
Intel choose to remove the option from the latest Bios...
The lesson of this all is that there may be other motherboard
implementations having the same of similar problems.
If you experience a lot of overrun errors during a backup to tape,
see if there is some setting in the Bios that may influence the
bus timing.
I judge this a hardware problem and not a limitation of ftape ;-)
My DOS backup software seems to be suffering from the same problems
and even refuses to run at 1 Mbps !
Ftape will reduce the data-rate from 1 Mbps to 500 Kbps if the number
of overrun errors on a track exceeds a threshold.
Possible solutions:
-------------------
Some of the problems were solved by upgrading the (flash) bios.
Other suggest that it has to do with the FDC being on the PCI
bus, but that is not the case with the Intel Premiere II boards.
[If upgrading the bios doesn't solve the problem you could try
a floppy disk controller on the isa-bus].
Here is a list of systems and recommended BIOS settings:
Intel Premiere PCI (Revenge):
Bios version 1.00.09.AF2 is reported to work.
Intel Premiere PCI II (Plato):
Bios version 1.00.10.AX1 and version 11 beta are ok.
If using version 1.00.08.AX1, GAT must be disabled !
ASUS PCI/I-SP3G:
Preferred settings: ISA-GAT-mode : disabled
DMA-linebuffer-mode : standard
ISA-masterbuffer-mode : standard
DELL Dimension XPS P90
Bios version A2 is reported to be broken, while bios version A5 works.
You can get a flash bios upgrade from http://www.dell.com
To see if you're having the GAT problem, try making a backup
under DOS. If it's very slow and often repositions you're
probably having this problem.

/* COMPRESS.H */
/* */
/******************************************************************************/
/* */
/* Author : Ross Williams. */
/* Date : December 1989. */
/* */
/* This header file defines the interface to a set of functions called */
/* 'compress', each member of which implements a particular data compression */
/* algorithm. */
/* */
/* Normally in C programming, for each .H file, there is a corresponding .C */
/* file that implements the functions promised in the .H file. */
/* Here, there are many .C files corresponding to this header file. */
/* Each comforming implementation file contains a single function */
/* called 'compress' that implements a single data compression */
/* algorithm that conforms with the interface specified in this header file. */
/* Only one algorithm can be linked in at a time in this organization. */
/* */
/******************************************************************************/
/* */
/* DEFINITION OF FUNCTION COMPRESS */
/* =============================== */
/* */
/* Summary of Function Compress */
/* ---------------------------- */
/* The action that 'compress' takes depends on its first argument called */
/* 'action'. The function provides three actions: */
/* */
/* - Return information about the algorithm. */
/* - Compress a block of memory. */
/* - Decompress a block of memory. */
/* */
/* Parameters */
/* ---------- */
/* See the formal C definition later for a description of the parameters. */
/* */
/* Constants */
/* --------- */
/* COMPRESS_OVERRUN: The constant COMPRESS_OVERRUN defines by how many bytes */
/* an algorithm is allowed to expand a block during a compression operation. */
/* */
/* Although compression algorithms usually compress data, there will always */
/* be data that a given compressor will expand (this can be proven). */
/* Fortunately, the degree of expansion can be limited to a single bit, by */
/* copying over the input data if the data gets bigger during compression. */
/* To allow for this possibility, the first bit of a compressed */
/* representation can be used as a flag indicating whether the */
/* input data was copied over, or truly compressed. In practice, the first */
/* byte would be used to store this bit so as to maintain byte alignment. */
/* */
/* Unfortunately, in general, the only way to tell if an algorithm will */
/* expand a particular block of data is to run the algorithm on the data. */
/* If the algorithm does not continuously monitor how many output bytes it */
/* has written, it might write an output block far larger than the input */
/* block before realizing that it has done so. */
/* On the other hand, continuous checks on output length are inefficient. */
/* */
/* To cater for all these problems, this interface definition: */
/* > Allows a compression algorithm to return an output block that is up to */
/* COMPRESS_OVERRUN bytes longer than the input block. */
/* > Allows a compression algorithm to write up to COMPRESS_OVERRUN bytes */
/* more than the length of the input block to the memory of the output */
/* block regardless of the length of the output block eventually returned. */
/* This allows an algorithm to overrun the length of the input block in the */
/* output block by up to COMPRESS_OVERRUN bytes between expansion checks. */
/* */
/* The problem does not arise for decompression. */
/* */
/* Identity Action */
/* --------------- */
/* > action must be COMPRESS_ACTION_IDENTITY. */
/* > p_dst_len must point to a longword to receive a longword address. */
/* > The value of the other parameters does not matter. */
/* > After execution, the longword that p_dst_len points to will be a pointer */
/* to a structure of type compress_identity. */
/* Thus, for example, after the call, (*p_dst_len)->memory will return the */
/* number of bytes of working memory that the algorithm requires to run. */
/* > The values of the identity structure returned are fixed constant */
/* attributes of the algorithm and must not vary from call to call. */
/* */
/* Common Requirements for Compression and Decompression Actions */
/* ------------------------------------------------------------- */
/* > wrk_mem must point to an unused block of memory of a length specified in */
/* the algorithm's identity block. The identity block can be obtained by */
/* making a separate call to compress, specifying the identity action. */
/* > The INPUT BLOCK is defined to be Memory[src_addr,src_addr+src_len-1]. */
/* > dst_len will be used to denote *p_dst_len. */
/* > dst_len is not read by compress, only written. */
/* > The value of dst_len is defined only upon termination. */
/* > The OUTPUT BLOCK is defined to be Memory[dst_addr,dst_addr+dst_len-1]. */
/* */
/* Compression Action */
/* ------------------ */
/* > action must be COMPRESS_ACTION_COMPRESS. */
/* > src_len must be in the range [0,COMPRESS_MAX_ORG]. */
/* > The OUTPUT ZONE is defined to be */
/* Memory[dst_addr,dst_addr+src_len-1+COMPRESS_OVERRUN]. */
/* > The function can modify any part of the output zone regardless of the */
/* final length of the output block. */
/* > The input block and the output zone must not overlap. */
/* > dst_len will be in the range [0,src_len+COMPRESS_OVERRUN]. */
/* > dst_len will be in the range [0,COMPRESS_MAX_COM] (from prev fact). */
/* > The output block will consist of a representation of the input block. */
/* */
/* Decompression Action */
/* -------------------- */
/* > action must be COMPRESS_ACTION_DECOMPRESS. */
/* > The input block must be the result of an earlier compression operation. */
/* > If the previous fact is true, the following facts must also be true: */
/* > src_len will be in the range [0,COMPRESS_MAX_COM]. */
/* > dst_len will be in the range [0,COMPRESS_MAX_ORG]. */
/* > The input and output blocks must not overlap. */
/* > Only the output block is modified. */
/* > Upon termination, the output block will consist of the bytes contained */
/* in the input block passed to the earlier compression operation. */

The entire guts of this program was written by dosemu, modified to
record reads and writes to the ports in the 0x180-0x188 address space,
while running the CMS program TAPE.EXE V2.0.5 supplied with the drive.
Modified to use an array of addresses and generally cleaned up (made
much shorter) 4 June 94, dosemu isn't that good at writing short code it
would seem :-). Made independent of 0x180, but I doubt it will work
at any other address.
Modified for distribution with ftape source. 21 June 94, SJL.
Modifications on 20 October 95, by Daniel Cohen (catman@wpi.edu):
Modified to support different DMA, IRQ, and IO Ports. Borland's
Turbo Debugger in virtual 8086 mode (TD386.EXE with hardware breakpoints
provided by the TDH386.SYS Device Driver) was used on the CMS program
TAPE V4.0.5. I set breakpoints on I/O to ports 0x180-0x187. Note that
CMS's program will not successfully configure the tape drive if you set
breakpoints on IO Reads, but you can set them on IO Writes without problems.
Known problems:
- You can not use DMA Channels 5 or 7.
Modification on 29 January 96, by Daniel Cohen (catman@wpi.edu):
Modified to only accept IRQs 3 - 7, or 9. Since we can only send a 3 bit
number representing the IRQ to the card, special handling is required when
IRQ 9 is selected. IRQ 2 and 9 are the same, and we should request IRQ 9
from the kernel while telling the card to use IRQ 2. Thanks to Greg
Crider (gcrider@iclnet.org) for finding and locating this bug, as well as
testing the patch.
Modification on 11 December 96, by Claus Heine (claus@momo.math.rwth-aachen.de):
Modified a little to use variahle ft_fdc_base, ft_fdc_irq, ft_fdc_dma
instead of preprocessor symbols. Thus we can compile this into the module
or kernel and let the user specify the options as command line arguments.
