Subject: [Linux-parport] [RFC] remove the paride driver
Message-ID: <20211223113504.1117836-1-hch@lst.de>

Hi Jens,

the paride driver has been unmaintained for a while and is a significant
maintainance burden, including the fact that it is one of the last
users of the block layer bounce buffering code.  This patch suggest
to remove it assuming no users complain loduly.

Ondrej: you're the last known users, so please speak up if you still
have a use case!

From: Tetsuo Handa <penguin-kernel at i-love.sakura.ne.jp>

The paride driver has been long unmaintained, and probably unused for
a while.  It is a significant maintainance burdern and one of the last
few users of the block layer bounce buffering code.

-Linux and parallel port IDE devices
-===================================
-
-PARIDE v1.03   (c) 1997-8  Grant Guenther <grant at torque.net>
-
-1. Introduction
-===============
-
-Owing to the simplicity and near universality of the parallel port interface
-to personal computers, many external devices such as portable hard-disk,
-CD-ROM, LS-120 and tape drives use the parallel port to connect to their
-host computer.  While some devices (notably scanners) use ad-hoc methods
-to pass commands and data through the parallel port interface, most
-external devices are actually identical to an internal model, but with
-a parallel-port adapter chip added in.  Some of the original parallel port
-adapters were little more than mechanisms for multiplexing a SCSI bus.
-(The Iomega PPA-3 adapter used in the ZIP drives is an example of this
-approach).  Most current designs, however, take a different approach.
-The adapter chip reproduces a small ISA or IDE bus in the external device
-and the communication protocol provides operations for reading and writing
-device registers, as well as data block transfer functions.  Sometimes,
-the device being addressed via the parallel cable is a standard SCSI
-controller like an NCR 5380.  The "ditto" family of external tape
-drives use the ISA replicator to interface a floppy disk controller,
-which is then connected to a floppy-tape mechanism.  The vast majority
-of external parallel port devices, however, are now based on standard
-IDE type devices, which require no intermediate controller.  If one
-were to open up a parallel port CD-ROM drive, for instance, one would
-find a standard ATAPI CD-ROM drive, a power supply, and a single adapter
-that interconnected a standard PC parallel port cable and a standard
-IDE cable.  It is usually possible to exchange the CD-ROM device with
-any other device using the IDE interface.
-
-The document describes the support in Linux for parallel port IDE
-devices.  It does not cover parallel port SCSI devices, "ditto" tape
-drives or scanners.  Many different devices are supported by the
-parallel port IDE subsystem, including:
-
-	- MicroSolutions backpack CD-ROM
-	- MicroSolutions backpack PD/CD
-	- MicroSolutions backpack hard-drives
-	- MicroSolutions backpack 8000t tape drive
-	- SyQuest EZ-135, EZ-230 & SparQ drives
-	- Avatar Shark
-	- Imation Superdisk LS-120
-	- Maxell Superdisk LS-120
-	- FreeCom Power CD
-	- Hewlett-Packard 5GB and 8GB tape drives
-	- Hewlett-Packard 7100 and 7200 CD-RW drives
-
-as well as most of the clone and no-name products on the market.
-
-To support such a wide range of devices, PARIDE, the parallel port IDE
-subsystem, is actually structured in three parts.   There is a base
-paride module which provides a registry and some common methods for
-accessing the parallel ports.  The second component is a set of
-high-level drivers for each of the different types of supported devices:
-
-	===	=============
-	pd	IDE disk
-	pcd	ATAPI CD-ROM
-	pf	ATAPI disk
-	pt	ATAPI tape
-	pg	ATAPI generic
-	===	=============
-
-(Currently, the pg driver is only used with CD-R drives).
-
-The high-level drivers function according to the relevant standards.
-The third component of PARIDE is a set of low-level protocol drivers
-for each of the parallel port IDE adapter chips.  Thanks to the interest
-and encouragement of Linux users from many parts of the world,
-support is available for almost all known adapter protocols:

-2. Using the PARIDE subsystem
-=============================
-
-While configuring the Linux kernel, you may choose either to build
-the PARIDE drivers into your kernel, or to build them as modules.
-
-In either case, you will need to select "Parallel port IDE device support"
-as well as at least one of the high-level drivers and at least one
-of the parallel port communication protocols.  If you do not know
-what kind of parallel port adapter is used in your drive, you could
-begin by checking the file names and any text files on your DOS
-installation floppy.  Alternatively, you can look at the markings on
-the adapter chip itself.  That's usually sufficient to identify the
-correct device.
-
-You can actually select all the protocol modules, and allow the PARIDE
-subsystem to try them all for you.
-
-For the "brand-name" products listed above, here are the protocol
-and high-level drivers that you would use:
-
-	================	============	======	========
-	Manufacturer		Model		Driver	Protocol
-	================	============	======	========
-	MicroSolutions		CD-ROM		pcd	bpck
-	MicroSolutions		PD drive	pf	bpck
-	MicroSolutions		hard-drive	pd	bpck
-	MicroSolutions          8000t tape      pt      bpck
-	SyQuest			EZ, SparQ	pd	epat
-	Imation			Superdisk	pf	epat
-	Maxell                  Superdisk       pf      friq
-	Avatar			Shark		pd	epat
-	FreeCom			CD-ROM		pcd	frpw
-	Hewlett-Packard		5GB Tape	pt	epat
-	Hewlett-Packard		7200e (CD)	pcd	epat
-	Hewlett-Packard		7200e (CD-R)	pg	epat
-	================	============	======	========
-
-2.1  Configuring built-in drivers
----------------------------------
-
-We recommend that you get to know how the drivers work and how to
-configure them as loadable modules, before attempting to compile a
-kernel with the drivers built-in.
-
-If you built all of your PARIDE support directly into your kernel,
-and you have just a single parallel port IDE device, your kernel should
-locate it automatically for you.  If you have more than one device,
-you may need to give some command line options to your bootloader
-(eg: LILO), how to do that is beyond the scope of this document.
-
-The high-level drivers accept a number of command line parameters, all
-of which are documented in the source files in linux/drivers/block/paride.
-By default, each driver will automatically try all parallel ports it
-can find, and all protocol types that have been installed, until it finds
-a parallel port IDE adapter.  Once it finds one, the probe stops.  So,
-if you have more than one device, you will need to tell the drivers
-how to identify them.  This requires specifying the port address, the
-protocol identification number and, for some devices, the drive's
-chain ID.  While your system is booting, a number of messages are
-displayed on the console.  Like all such messages, they can be
-reviewed with the 'dmesg' command.  Among those messages will be
-some lines like::
-
-	paride: bpck registered as protocol 0
-	paride: epat registered as protocol 1
-
-The numbers will always be the same until you build a new kernel with
-different protocol selections.  You should note these numbers as you
-will need them to identify the devices.
-
-If you happen to be using a MicroSolutions backpack device, you will
-also need to know the unit ID number for each drive.  This is usually
-the last two digits of the drive's serial number (but read MicroSolutions'
-documentation about this).
-
-As an example, let's assume that you have a MicroSolutions PD/CD drive
-with unit ID number 36 connected to the parallel port at 0x378, a SyQuest
-EZ-135 connected to the chained port on the PD/CD drive and also an
-Imation Superdisk connected to port 0x278.  You could give the following
-options on your boot command::
-
-	pd.drive0=0x378,1 pf.drive0=0x278,1 pf.drive1=0x378,0,36
-
-In the last option, pf.drive1 configures device /dev/pf1, the 0x378
-is the parallel port base address, the 0 is the protocol registration
-number and 36 is the chain ID.
-
-Please note:  while PARIDE will work both with and without the
-PARPORT parallel port sharing system that is included by the
-"Parallel port support" option, PARPORT must be included and enabled
-if you want to use chains of devices on the same parallel port.
-
-2.2  Loading and configuring PARIDE as modules
-----------------------------------------------
-
-It is much faster and simpler to get to understand the PARIDE drivers
-if you use them as loadable kernel modules.
-
-Note 1:
-	using these drivers with the "kerneld" automatic module loading
-	system is not recommended for beginners, and is not documented here.
-
-Note 2:
-	if you build PARPORT support as a loadable module, PARIDE must
-	also be built as loadable modules, and PARPORT must be loaded before
-	the PARIDE modules.
-
-To use PARIDE, you must begin by::
-
-	insmod paride
-
-this loads a base module which provides a registry for the protocols,
-among other tasks.
-
-Then, load as many of the protocol modules as you think you might need.
-As you load each module, it will register the protocols that it supports,
-and print a log message to your kernel log file and your console. For
-example::
-
-	# insmod epat
-	paride: epat registered as protocol 0
-	# insmod kbic
-	paride: k951 registered as protocol 1
-        paride: k971 registered as protocol 2
-
-Finally, you can load high-level drivers for each kind of device that
-you have connected.  By default, each driver will autoprobe for a single
-device, but you can support up to four similar devices by giving their
-individual coordinates when you load the driver.
-
-For example, if you had two no-name CD-ROM drives both using the
-KingByte KBIC-951A adapter, one on port 0x378 and the other on 0x3bc
-you could give the following command::
-
-	# insmod pcd drive0=0x378,1 drive1=0x3bc,1
-
-For most adapters, giving a port address and protocol number is sufficient,
-but check the source files in linux/drivers/block/paride for more
-information.  (Hopefully someone will write some man pages one day !).
-
-As another example, here's what happens when PARPORT is installed, and
-a SyQuest EZ-135 is attached to port 0x378::
-
-	# insmod paride
-	paride: version 1.0 installed
-	# insmod epat
-	paride: epat registered as protocol 0
-	# insmod pd
-	pd: pd version 1.0, major 45, cluster 64, nice 0
-	pda: Sharing parport1 at 0x378
-	pda: epat 1.0, Shuttle EPAT chip c3 at 0x378, mode 5 (EPP-32), delay 1
-	pda: SyQuest EZ135A, 262144 blocks [128M], (512/16/32), removable media
-	 pda: pda1
-
-Note that the last line is the output from the generic partition table
-scanner - in this case it reports that it has found a disk with one partition.
-
-2.3  Using a PARIDE device
---------------------------
-
-Once the drivers have been loaded, you can access PARIDE devices in the
-same way as their traditional counterparts.  You will probably need to
-create the device "special files".  Here is a simple script that you can
-cut to a file and execute::
-
-  #!/bin/bash
-  #
-  # mkd -- a script to create the device special files for the PARIDE subsystem
-  #
-  function mkdev {
-    mknod $1 $2 $3 $4 ; chmod 0660 $1 ; chown root:disk $1
-  }
-  #
-  function pd {
-    D=$( printf \\$( printf "x%03x" $[ $1 + 97 ] ) )
-    mkdev pd$D b 45 $[ $1 * 16 ]
-    for P in 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15
-    do mkdev pd$D$P b 45 $[ $1 * 16 + $P ]
-    done
-  }
-  #
-  cd /dev
-  #
-  for u in 0 1 2 3 ; do pd $u ; done
-  for u in 0 1 2 3 ; do mkdev pcd$u b 46 $u ; done
-  for u in 0 1 2 3 ; do mkdev pf$u  b 47 $u ; done
-  for u in 0 1 2 3 ; do mkdev pt$u  c 96 $u ; done
-  for u in 0 1 2 3 ; do mkdev npt$u c 96 $[ $u + 128 ] ; done
-  for u in 0 1 2 3 ; do mkdev pg$u  c 97 $u ; done
-  #
-  # end of mkd
-
-With the device files and drivers in place, you can access PARIDE devices
-like any other Linux device.   For example, to mount a CD-ROM in pcd0, use::
-
-	mount /dev/pcd0 /cdrom
-
-If you have a fresh Avatar Shark cartridge, and the drive is pda, you
-might do something like::
-
-	fdisk /dev/pda		-- make a new partition table with
-				   partition 1 of type 83
-
-	mke2fs /dev/pda1	-- to build the file system
-
-	mkdir /shark		-- make a place to mount the disk
-
-	mount /dev/pda1 /shark
-
-Devices like the Imation superdisk work in the same way, except that
-they do not have a partition table.  For example to make a 120MB
-floppy that you could share with a DOS system::
-
-	mkdosfs /dev/pf0
-	mount /dev/pf0 /mnt
-
-
-2.4  The pf driver
-------------------
-
-The pf driver is intended for use with parallel port ATAPI disk
-devices.  The most common devices in this category are PD drives
-and LS-120 drives.  Traditionally, media for these devices are not
-partitioned.  Consequently, the pf driver does not support partitioned
-media.  This may be changed in a future version of the driver.
-
-2.5  Using the pt driver
-------------------------
-
-The pt driver for parallel port ATAPI tape drives is a minimal driver.
-It does not yet support many of the standard tape ioctl operations.
-For best performance, a block size of 32KB should be used.  You will
-probably want to set the parallel port delay to 0, if you can.
-
-2.6  Using the pg driver
-------------------------
-
-The pg driver can be used in conjunction with the cdrecord program
-to create CD-ROMs.  Please get cdrecord version 1.6.1 or later
-from ftp://ftp.fokus.gmd.de/pub/unix/cdrecord/ .  To record CD-R media
-your parallel port should ideally be set to EPP mode, and the "port delay"
-should be set to 0.  With those settings it is possible to record at 2x
-speed without any buffer underruns.  If you cannot get the driver to work
-in EPP mode, try to use "bidirectional" or "PS/2" mode and 1x speeds only.
-
-
-3. Troubleshooting
-==================
-
-3.1  Use EPP mode if you can
-----------------------------
-
-The most common problems that people report with the PARIDE drivers
-concern the parallel port CMOS settings.  At this time, none of the
-PARIDE protocol modules support ECP mode, or any ECP combination modes.
-If you are able to do so, please set your parallel port into EPP mode
-using your CMOS setup procedure.
-
-3.2  Check the port delay
--------------------------
-
-Some parallel ports cannot reliably transfer data at full speed.  To
-offset the errors, the PARIDE protocol modules introduce a "port
-delay" between each access to the i/o ports.  Each protocol sets
-a default value for this delay.  In most cases, the user can override
-the default and set it to 0 - resulting in somewhat higher transfer
-rates.  In some rare cases (especially with older 486 systems) the
-default delays are not long enough.  if you experience corrupt data
-transfers, or unexpected failures, you may wish to increase the
-port delay.   The delay can be programmed using the "driveN" parameters
-to each of the high-level drivers.  Please see the notes above, or
-read the comments at the beginning of the driver source files in
-linux/drivers/block/paride.
-
-3.3  Some drives need a printer reset
--------------------------------------
-
-There appear to be a number of "noname" external drives on the market
-that do not always power up correctly.  We have noticed this with some
-drives based on OnSpec and older Freecom adapters.  In these rare cases,
-the adapter can often be reinitialised by issuing a "printer reset" on
-the parallel port.  As the reset operation is potentially disruptive in
-multiple device environments, the PARIDE drivers will not do it
-automatically.  You can however, force a printer reset by doing::
-
-	insmod lp reset=1
-	rmmod lp
-
-If you have one of these marginal cases, you should probably build
-your paride drivers as modules, and arrange to do the printer reset
-before loading the PARIDE drivers.
-
-3.4  Use the verbose option and dmesg if you need help
-------------------------------------------------------
-
-While a lot of testing has gone into these drivers to make them work
-as smoothly as possible, problems will arise.  If you do have problems,
-please check all the obvious things first:  does the drive work in
-DOS with the manufacturer's drivers ?  If that doesn't yield any useful
-clues, then please make sure that only one drive is hooked to your system,
-and that either (a) PARPORT is enabled or (b) no other device driver
-is using your parallel port (check in /proc/ioports).  Then, load the
-appropriate drivers (you can load several protocol modules if you want)
-as in::
-
-	# insmod paride
-	# insmod epat
-	# insmod bpck
-	# insmod kbic
-	...
-	# insmod pd verbose=1
-
-(using the correct driver for the type of device you have, of course).
-The verbose=1 parameter will cause the drivers to log a trace of their
-activity as they attempt to locate your drive.
-
-Use 'dmesg' to capture a log of all the PARIDE messages (any messages
-beginning with paride:, a protocol module's name or a driver's name) and
-include that with your bug report.  You can submit a bug report in one
-of two ways.  Either send it directly to the author of the PARIDE suite,
-by e-mail to grant at torque.net, or join the linux-parport mailing list
-and post your report there.
-
-3.5  For more information or help
----------------------------------
-
-You can join the linux-parport mailing list by sending a mail message
-to:
-
-		linux-parport-request at torque.net
-
-with the single word::
-
-		subscribe
-
-in the body of the mail message (not in the subject line).   Please be
-sure that your mail program is correctly set up when you do this,  as
-the list manager is a robot that will subscribe you using the reply
-address in your mail headers.  REMOVE any anti-spam gimmicks you may
-have in your mail headers, when sending mail to the list server.
-
-You might also find some useful information on the linux-parport
-web pages (although they are not always up to date) at

-Lemma 1:
-	If ps_tq is scheduled, ps_tq_active is 1.  ps_tq_int() can be called
-	only when ps_tq_active is 1.
-Proof:	All assignments to ps_tq_active and all scheduling of ps_tq happen
-	under ps_spinlock.  There are three places where that can happen:
-	one in ps_set_intr() (A) and two in ps_tq_int() (B and C).
-	Consider the sequnce of these events.  A can not be preceded by
-	anything except B, since it is under if (!ps_tq_active) under
-	ps_spinlock.  C is always preceded by B, since we can't reach it
-	other than through B and we don't drop ps_spinlock between them.
-	IOW, the sequence is A?(BA|BC|B)*.  OTOH, number of B can not exceed
-	the sum of numbers of A and C, since each call of ps_tq_int() is
-	the result of ps_tq execution.  Therefore, the sequence starts with
-	A and each B is preceded by either A or C.  Moments when we enter
-	ps_tq_int() are sandwiched between {A,C} and B in that sequence,
-	since at any time number of B can not exceed the number of these
-	moments which, in turn, can not exceed the number of A and C.
-	In other words, the sequence of events is (A or C set ps_tq_active to
-	1 and schedule ps_tq, ps_tq is executed, ps_tq_int() is entered,
-	B resets ps_tq_active)*.
-
-
-consider the following area:
-	* in do_pd_request1(): to calls of pi_do_claimed() and return in
-	  case when pd_req is NULL.
-	* in next_request(): to call of do_pd_request1()
-	* in do_pd_read(): to call of ps_set_intr()
-	* in do_pd_read_start(): to calls of pi_do_claimed(), next_request()
-and ps_set_intr()
-	* in do_pd_read_drq(): to calls of pi_do_claimed() and next_request()
-	* in do_pd_write(): to call of ps_set_intr()
-	* in do_pd_write_start(): to calls of pi_do_claimed(), next_request()
-and ps_set_intr()
-	* in do_pd_write_done(): to calls of pi_do_claimed() and next_request()
-	* in ps_set_intr(): to check for ps_tq_active and to scheduling
-	  ps_tq if ps_tq_active was 0.
-	* in ps_tq_int(): from the moment when we get ps_spinlock() to the
-	  return, call of con() or scheduling ps_tq.
-	* in pi_schedule_claimed() when called from pi_do_claimed() called from
-	  pd.c, everything until returning 1 or setting or setting ->claim_cont
-	  on the path that returns 0
-	* in pi_do_claimed() when called from pd.c, everything until the call
-	  of pi_do_claimed() plus the everything until the call of cont() if
-	  pi_do_claimed() has returned 1.
-	* in pi_wake_up() called for PIA that belongs to pd.c, everything from
-	  the moment when pi_spinlock has been acquired.
-
-Lemma 2:
-	1) at any time at most one thread of execution can be in that area or
-	be preempted there.
-	2) When there is such a thread, pd_busy is set or pd_lock is held by
-	that thread.
-	3) When there is such a thread, ps_tq_active is 0 or ps_spinlock is
-	held by that thread.
-	4) When there is such a thread, all PIA belonging to pd.c have NULL
-	->claim_cont or pi_spinlock is held by thread in question.
-
-Proof:	consider the first moment when the above is not true.
-
-(1) can become not true if some thread enters that area while another is there.
-	a) do_pd_request1() can be called from next_request() or do_pd_request()
-	   In the first case the thread was already in the area.  In the second,
-	   the thread was holding pd_lock and found pd_busy not set, which would
-	   mean that (2) was already not true.
-	b) ps_set_intr() and pi_schedule_claimed() can be called only from the
-	   area.
-	c) pi_do_claimed() is called by pd.c only from the area.
-	d) ps_tq_int() can enter the area only when the thread is holding
-	   ps_spinlock and ps_tq_active is 1 (due to Lemma 1).  It means that
-	   (3) was already not true.
-	e) do_pd_{read,write}* could be called only from the area.  The only
-	   case that needs consideration is call from pi_wake_up() and there
-	   we would have to be called for the PIA that got ->claimed_cont
-	   from pd.c.  That could happen only if pi_do_claimed() had been
-	   called from pd.c for that PIA, which happens only for PIA belonging
-	   to pd.c.
-	f) pi_wake_up() can enter the area only when the thread is holding
-	   pi_spinlock and ->claimed_cont is non-NULL for PIA belonging to
-	   pd.c.  It means that (4) was already not true.
-
-(2) can become not true only when pd_lock is released by the thread in question.
-	Indeed, pd_busy is reset only in the area and thread that resets
-	it is holding pd_lock.	The only place within the area where we
-	release pd_lock is in pd_next_buf() (called from within the area).
-	But that code does not reset pd_busy, so pd_busy would have to be
-	0 when pd_next_buf() had acquired pd_lock.  If it become 0 while
-	we were acquiring the lock, (1) would be already false, since
-	the thread that had reset it would be in the area simulateously.
-	If it was 0 before we tried to acquire pd_lock, (2) would be
-	already false.
-
-For similar reasons, (3) can become not true only when ps_spinlock is released
-by the thread in question.  However, all such places within the area are right
-after resetting ps_tq_active to 0.
-
-(4) is done the same way - all places where we release pi_spinlock within
-the area are either after resetting ->claimed_cont to NULL while holding
-pi_spinlock, or after not tocuhing ->claimed_cont since acquiring pi_spinlock
-also in the area.  The only place where ->claimed_cont is made non-NULL is
-in the area, under pi_spinlock and we do not release it until after leaving
-the area.
-
-QED.
-
-
-Corollary 1: ps_tq_active can be killed.  Indeed, the only place where we
-check its value is in ps_set_intr() and if it had been non-zero at that
-point, we would have violated either (2.1) (if it was set while ps_set_intr()
-was acquiring ps_spinlock) or (2.3) (if it was set when we started to
-acquire ps_spinlock).
-
-Corollary 2: ps_spinlock can be killed.  Indeed, Lemma 1 and Lemma 2 show
-that the only possible contention is between scheduling ps_tq followed by
-immediate release of spinlock and beginning of execution of ps_tq on
-another CPU.
-
-Corollary 3: assignment to pd_busy in do_pd_read_start() and do_pd_write_start()
-can be killed.  Indeed, we are not holding pd_lock and thus pd_busy is already
-1 here.
-
-Corollary 4: in ps_tq_int() uses of con can be replaced with uses of
-ps_continuation, since the latter is changed only from the area.
-We don't need to reset it to NULL, since we are guaranteed that there
-will be a call of ps_set_intr() before we look at ps_continuation again.
-We can remove the check for ps_continuation being NULL for the same
-reason - the value is guaranteed to be set by the last ps_set_intr() and
-we never pass it NULL.  Assignements in the beginning of ps_set_intr()
-can be taken to callers as long as they remain within the area.

-	friq.c is a low-level protocol driver for the Freecom "IQ"
-	parallel port IDE adapter.   Early versions of this adapter
-	use the 'frpw' protocol.
-	
-	Freecom uses this adapter in a battery powered external 
-	CD-ROM drive.  It is also used in LS-120 drives by
-	Maxell and Panasonic, and other devices.
-
-	The battery powered drive requires software support to
-	control the power to the drive.  This module enables the
-	drive power when the high level driver (pcd) is loaded
-	and disables it when the module is unloaded.  Note, if
-	the friq module is built in to the kernel, the power
-	will never be switched off, so other means should be
-	used to conserve battery power.

-
-	This is a high-level driver for parallel port ATAPI CD-ROM
-        drives based on chips supported by the paride module.
-
-        By default, the driver will autoprobe for a single parallel
-        port ATAPI CD-ROM drive, but if their individual parameters are
-        specified, the driver can handle up to 4 drives.
-
-        The behaviour of the pcd driver can be altered by setting
-        some parameters from the insmod command line.  The following
-        parameters are adjustable:
-
-            drive0      These four arguments can be arrays of       
-            drive1      1-6 integers as follows:
-            drive2
-            drive3      <prt>,<pro>,<uni>,<mod>,<slv>,<dly>
-
-                        Where,
-
-                <prt>   is the base of the parallel port address for
-                        the corresponding drive.  (required)
-
-                <pro>   is the protocol number for the adapter that
-                        supports this drive.  These numbers are
-                        logged by 'paride' when the protocol modules
-                        are initialised.  (0 if not given)
-
-                <uni>   for those adapters that support chained
-                        devices, this is the unit selector for the
-                        chain of devices on the given port.  It should
-                        be zero for devices that don't support chaining.
-                        (0 if not given)
-
-                <mod>   this can be -1 to choose the best mode, or one
-                        of the mode numbers supported by the adapter.
-                        (-1 if not given)
-
-		<slv>   ATAPI CD-ROMs can be jumpered to master or slave.
-			Set this to 0 to choose the master drive, 1 to
-                        choose the slave, -1 (the default) to choose the
-			first drive found.
-
-                <dly>   some parallel ports require the driver to 
-                        go more slowly.  -1 sets a default value that
-                        should work with the chosen protocol.  Otherwise,
-                        set this to a small integer, the larger it is
-                        the slower the port i/o.  In some cases, setting
-                        this to zero will speed up the device. (default -1)
-                        
-            major       You may use this parameter to override the
-                        default major number (46) that this driver
-                        will use.  Be sure to change the device
-                        name as well.
-
-            name        This parameter is a character string that
-                        contains the name the kernel will use for this
-                        device (in /proc output, for instance).
-                        (default "pcd")
-
-            verbose     This parameter controls the amount of logging
-                        that the driver will do.  Set it to 0 for
-                        normal operation, 1 to see autoprobe progress
-                        messages, or 2 to see additional debugging
-                        output.  (default 0)
-  
-            nice        This parameter controls the driver's use of
-                        idle CPU time, at the expense of some speed.
- 
-	If this driver is built into the kernel, you can use the
-        following kernel command line parameters, with the same values
-        as the corresponding module parameters listed above:
-
-	    pcd.drive0
-	    pcd.drive1
-	    pcd.drive2
-	    pcd.drive3
-	    pcd.nice
-
-        In addition, you can use the parameter pcd.disable to disable
-        the driver entirely.

-        pd.c    (c) 1997-8  Grant R. Guenther <grant at torque.net>
-                            Under the terms of the GNU General Public License.
-
-        This is the high-level driver for parallel port IDE hard
-        drives based on chips supported by the paride module.
-
-	By default, the driver will autoprobe for a single parallel
-	port IDE drive, but if their individual parameters are
-        specified, the driver can handle up to 4 drives.
-
-        The behaviour of the pd driver can be altered by setting
-        some parameters from the insmod command line.  The following
-        parameters are adjustable:
- 
-	    drive0  	These four arguments can be arrays of	    
-	    drive1	1-8 integers as follows:
-	    drive2
-	    drive3	<prt>,<pro>,<uni>,<mod>,<geo>,<sby>,<dly>,<slv>
-
-			Where,
-
-		<prt>	is the base of the parallel port address for
-			the corresponding drive.  (required)
-
-		<pro>   is the protocol number for the adapter that
-			supports this drive.  These numbers are
-                        logged by 'paride' when the protocol modules
-			are initialised.  (0 if not given)
-
-		<uni>   for those adapters that support chained
-			devices, this is the unit selector for the
-		        chain of devices on the given port.  It should
-			be zero for devices that don't support chaining.
-			(0 if not given)
-
-		<mod>   this can be -1 to choose the best mode, or one
-		        of the mode numbers supported by the adapter.
-			(-1 if not given)
-
-		<geo>   this defaults to 0 to indicate that the driver
-			should use the CHS geometry provided by the drive
-			itself.  If set to 1, the driver will provide
-			a logical geometry with 64 heads and 32 sectors
-			per track, to be consistent with most SCSI
-		        drivers.  (0 if not given)
-
-		<sby>   set this to zero to disable the power saving
-			standby mode, if needed.  (1 if not given)
-
-		<dly>   some parallel ports require the driver to 
-			go more slowly.  -1 sets a default value that
-			should work with the chosen protocol.  Otherwise,
-			set this to a small integer, the larger it is
-			the slower the port i/o.  In some cases, setting
-			this to zero will speed up the device. (default -1)
-
-		<slv>   IDE disks can be jumpered to master or slave.
-                        Set this to 0 to choose the master drive, 1 to
-                        choose the slave, -1 (the default) to choose the
-                        first drive found.
-			
-
-            major       You may use this parameter to override the
-                        default major number (45) that this driver
-                        will use.  Be sure to change the device
-                        name as well.
-
-            name        This parameter is a character string that
-                        contains the name the kernel will use for this
-                        device (in /proc output, for instance).
-			(default "pd")
-
-	    cluster	The driver will attempt to aggregate requests
-			for adjacent blocks into larger multi-block
-			clusters.  The maximum cluster size (in 512
-			byte sectors) is set with this parameter.
-			(default 64)
-
-	    verbose	This parameter controls the amount of logging
-			that the driver will do.  Set it to 0 for 
-			normal operation, 1 to see autoprobe progress
-			messages, or 2 to see additional debugging
-			output.  (default 0)
-
-            nice        This parameter controls the driver's use of
-                        idle CPU time, at the expense of some speed.
-
-        If this driver is built into the kernel, you can use kernel
-        the following command line parameters, with the same values
-        as the corresponding module parameters listed above:
-
-            pd.drive0
-            pd.drive1
-            pd.drive2
-            pd.drive3
-            pd.cluster
-            pd.nice
-
-        In addition, you can use the parameter pd.disable to disable
-        the driver entirely.

-
-        This is the high-level driver for parallel port ATAPI disk
-        drives based on chips supported by the paride module.
-
-        By default, the driver will autoprobe for a single parallel
-        port ATAPI disk drive, but if their individual parameters are
-        specified, the driver can handle up to 4 drives.
-
-        The behaviour of the pf driver can be altered by setting
-        some parameters from the insmod command line.  The following
-        parameters are adjustable:
-
-            drive0      These four arguments can be arrays of       
-            drive1      1-7 integers as follows:
-            drive2
-            drive3      <prt>,<pro>,<uni>,<mod>,<slv>,<lun>,<dly>
-
-                        Where,
-
-                <prt>   is the base of the parallel port address for
-                        the corresponding drive.  (required)
-
-                <pro>   is the protocol number for the adapter that
-                        supports this drive.  These numbers are
-                        logged by 'paride' when the protocol modules
-                        are initialised.  (0 if not given)
-
-                <uni>   for those adapters that support chained
-                        devices, this is the unit selector for the
-                        chain of devices on the given port.  It should
-                        be zero for devices that don't support chaining.
-                        (0 if not given)
-
-                <mod>   this can be -1 to choose the best mode, or one
-                        of the mode numbers supported by the adapter.
-                        (-1 if not given)
-
-                <slv>   ATAPI CDroms can be jumpered to master or slave.
-                        Set this to 0 to choose the master drive, 1 to
-                        choose the slave, -1 (the default) to choose the
-                        first drive found.
-
-		<lun>   Some ATAPI devices support multiple LUNs.
-                        One example is the ATAPI PD/CD drive from
-                        Matshita/Panasonic.  This device has a 
-                        CD drive on LUN 0 and a PD drive on LUN 1.
-                        By default, the driver will search for the
-                        first LUN with a supported device.  Set 
-                        this parameter to force it to use a specific
-                        LUN.  (default -1)
-
-                <dly>   some parallel ports require the driver to 
-                        go more slowly.  -1 sets a default value that
-                        should work with the chosen protocol.  Otherwise,
-                        set this to a small integer, the larger it is
-                        the slower the port i/o.  In some cases, setting
-                        this to zero will speed up the device. (default -1)
-
-	    major	You may use this parameter to override the
-			default major number (47) that this driver
-			will use.  Be sure to change the device
-			name as well.
-
-	    name	This parameter is a character string that
-			contains the name the kernel will use for this
-			device (in /proc output, for instance).
-			(default "pf").
-
-            cluster     The driver will attempt to aggregate requests
-                        for adjacent blocks into larger multi-block
-                        clusters.  The maximum cluster size (in 512
-                        byte sectors) is set with this parameter.
-                        (default 64)
-
-            verbose     This parameter controls the amount of logging
-                        that the driver will do.  Set it to 0 for
-                        normal operation, 1 to see autoprobe progress
-                        messages, or 2 to see additional debugging
-                        output.  (default 0)
- 
-	    nice        This parameter controls the driver's use of
-			idle CPU time, at the expense of some speed.
-
-        If this driver is built into the kernel, you can use the
-        following command line parameters, with the same values
-        as the corresponding module parameters listed above:
-
-            pf.drive0
-            pf.drive1
-            pf.drive2
-            pf.drive3
-	    pf.cluster
-            pf.nice
-
-        In addition, you can use the parameter pf.disable to disable
-        the driver entirely.

-/* 
-	pg.c    (c) 1998  Grant R. Guenther <grant at torque.net>
-			  Under the terms of the GNU General Public License.
-
-	The pg driver provides a simple character device interface for
-	sending ATAPI commands to a device.  With the exception of the
-	ATAPI reset operation, all operations are performed by a pair
-	of read and write operations to the appropriate /dev/pgN device.
-	A write operation delivers a command and any outbound data in
-	a single buffer.  Normally, the write will succeed unless the
-	device is offline or malfunctioning, or there is already another
-	command pending.  If the write succeeds, it should be followed
-	immediately by a read operation, to obtain any returned data and
-	status information.  A read will fail if there is no operation
-	in progress.
-
-	As a special case, the device can be reset with a write operation,
-	and in this case, no following read is expected, or permitted.
-
-	There are no ioctl() operations.  Any single operation
-	may transfer at most PG_MAX_DATA bytes.  Note that the driver must
-	copy the data through an internal buffer.  In keeping with all
-	current ATAPI devices, command packets are assumed to be exactly
-	12 bytes in length.
-
-	To permit future changes to this interface, the headers in the
-	read and write buffers contain a single character "magic" flag.
-	Currently this flag must be the character "P".
-
-	By default, the driver will autoprobe for a single parallel
-	port ATAPI device, but if their individual parameters are
-	specified, the driver can handle up to 4 devices.
-
-	To use this device, you must have the following device 
-	special files defined:
-
-		/dev/pg0 c 97 0
-		/dev/pg1 c 97 1
-		/dev/pg2 c 97 2
-		/dev/pg3 c 97 3
-
-	(You'll need to change the 97 to something else if you use
-	the 'major' parameter to install the driver on a different
-	major number.)
-
-	The behaviour of the pg driver can be altered by setting
-	some parameters from the insmod command line.  The following
-	parameters are adjustable:
-
-	    drive0      These four arguments can be arrays of       
-	    drive1      1-6 integers as follows:
-	    drive2
-	    drive3      <prt>,<pro>,<uni>,<mod>,<slv>,<dly>
-
-			Where,
-
-		<prt>   is the base of the parallel port address for
-			the corresponding drive.  (required)
-
-		<pro>   is the protocol number for the adapter that
-			supports this drive.  These numbers are
-			logged by 'paride' when the protocol modules
-			are initialised.  (0 if not given)
-
-		<uni>   for those adapters that support chained
-			devices, this is the unit selector for the
-			chain of devices on the given port.  It should
-			be zero for devices that don't support chaining.
-			(0 if not given)
-
-		<mod>   this can be -1 to choose the best mode, or one
-			of the mode numbers supported by the adapter.
-			(-1 if not given)
-
-		<slv>   ATAPI devices can be jumpered to master or slave.
-			Set this to 0 to choose the master drive, 1 to
-			choose the slave, -1 (the default) to choose the
-			first drive found.
-
-		<dly>   some parallel ports require the driver to 
-			go more slowly.  -1 sets a default value that
-			should work with the chosen protocol.  Otherwise,
-			set this to a small integer, the larger it is
-			the slower the port i/o.  In some cases, setting
-			this to zero will speed up the device. (default -1)
-
-	    major	You may use this parameter to override the
-			default major number (97) that this driver
-			will use.  Be sure to change the device
-			name as well.
-
-	    name	This parameter is a character string that
-			contains the name the kernel will use for this
-			device (in /proc output, for instance).
-			(default "pg").
-
-	    verbose     This parameter controls the amount of logging
-			that is done by the driver.  Set it to 0 for 
-			quiet operation, to 1 to enable progress
-			messages while the driver probes for devices,
-			or to 2 for full debug logging.  (default 0)
-
-	If this driver is built into the kernel, you can use 
-	the following command line parameters, with the same values
-	as the corresponding module parameters listed above:
-
-	    pg.drive0
-	    pg.drive1
-	    pg.drive2
-	    pg.drive3
-
-	In addition, you can use the parameter pg.disable to disable
-	the driver entirely.

-
-        This is the high-level driver for parallel port ATAPI tape
-        drives based on chips supported by the paride module.
-
-	The driver implements both rewinding and non-rewinding
-	devices, filemarks, and the rewind ioctl.  It allocates
-	a small internal "bounce buffer" for each open device, but
-        otherwise expects buffering and blocking to be done at the
-        user level.  As with most block-structured tapes, short
-	writes are padded to full tape blocks, so reading back a file
-        may return more data than was actually written.
-
-        By default, the driver will autoprobe for a single parallel
-        port ATAPI tape drive, but if their individual parameters are
-        specified, the driver can handle up to 4 drives.
-
-	The rewinding devices are named /dev/pt0, /dev/pt1, ...
-	while the non-rewinding devices are /dev/npt0, /dev/npt1, etc.
-
-        The behaviour of the pt driver can be altered by setting
-        some parameters from the insmod command line.  The following
-        parameters are adjustable:
-
-            drive0      These four arguments can be arrays of       
-            drive1      1-6 integers as follows:
-            drive2
-            drive3      <prt>,<pro>,<uni>,<mod>,<slv>,<dly>
-
-                        Where,
-
-                <prt>   is the base of the parallel port address for
-                        the corresponding drive.  (required)
-
-                <pro>   is the protocol number for the adapter that
-                        supports this drive.  These numbers are
-                        logged by 'paride' when the protocol modules
-                        are initialised.  (0 if not given)
-
-                <uni>   for those adapters that support chained
-                        devices, this is the unit selector for the
-                        chain of devices on the given port.  It should
-                        be zero for devices that don't support chaining.
-                        (0 if not given)
-
-                <mod>   this can be -1 to choose the best mode, or one
-                        of the mode numbers supported by the adapter.
-                        (-1 if not given)
-
-                <slv>   ATAPI devices can be jumpered to master or slave.
-                        Set this to 0 to choose the master drive, 1 to
-                        choose the slave, -1 (the default) to choose the
-                        first drive found.
-
-                <dly>   some parallel ports require the driver to 
-                        go more slowly.  -1 sets a default value that
-                        should work with the chosen protocol.  Otherwise,
-                        set this to a small integer, the larger it is
-                        the slower the port i/o.  In some cases, setting
-                        this to zero will speed up the device. (default -1)
-
-	    major	You may use this parameter to override the
-			default major number (96) that this driver
-			will use.  Be sure to change the device
-			name as well.
-
-	    name	This parameter is a character string that
-			contains the name the kernel will use for this
-			device (in /proc output, for instance).
-			(default "pt").
-
-            verbose     This parameter controls the amount of logging
-                        that the driver will do.  Set it to 0 for
-                        normal operation, 1 to see autoprobe progress
-                        messages, or 2 to see additional debugging
-                        output.  (default 0)
- 
-        If this driver is built into the kernel, you can use 
-        the following command line parameters, with the same values
-        as the corresponding module parameters listed above:
-
-            pt.drive0
-            pt.drive1
-            pt.drive2
-            pt.drive3
-
-        In addition, you can use the parameter pt.disable to disable
-        the driver entirely.

It really should be removed imho. To give folks a chance to pipe up,
might be more reasonable to queue it up post the 5.17 merge window. I
expect a lot of people are going to be less attentive the next few weeks
than usual, and that really isn't a lot of warning to give even with an
-rc8 planned.

Looks like I really need to do the libata conversion.

That would indeed be great! As mentioned in my reply, I don't want to
remove drivers that are actively being used. Is the libata conversion
something you are going to do, or is it more of a dream at this point?
Ideally we get that done first, and then remove paride.

Haven't started yet. But I'm increasing its priority in my todo list.

Ok.  We'll keep the paride code in the current from for now then.
