-  <para>
-This document outlines the interface between the Linux scsi mid level
-and lower level drivers. Lower level drivers are variously called HBA
-(host bus adapter) drivers, host drivers (HD) or pseudo adapter drivers.
-The latter alludes to the fact that a lower level driver may be a
-bridge to another IO subsystem (and the "ide-scsi" driver is an example
-of this). There can be many lower level drivers active in a running
-system, but only one per hardware type. For example, the aic7xxx driver
-controls adaptec controllers based on the 7xxx chip series. Most lower
-level drivers can control one or more scsi hosts (a.k.a. scsi initiators).
-  </para>
-<para>
-This document can been found in an ASCII text file in the linux kernel 
-source: <filename>Documentation/scsi/scsi_mid_low_api.txt</filename> .
-It currently hold a little more information than this document. The
-<filename>drivers/scsi/hosts.h</filename> and <filename>
-drivers/scsi/scsi.h</filename> headers contain descriptions of members
-of important structures for the scsi subsystem.

-  <chapter id="driver-struct">
-      <title>Driver structure</title>
-  <para>
-Traditionally a lower level driver for the scsi subsystem has been
-at least two files in the drivers/scsi directory. For example, a
-driver called "xyz" has a header file "xyz.h" and a source file
-"xyz.c". [Actually there is no good reason why this couldn't all
-be in one file.] Some drivers that have been ported to several operating
-systems (e.g. aic7xxx which has separate  files for generic and
-OS-specific code) have more than two files. Such drivers tend to have
-their own directory under the drivers/scsi directory.
-  </para>
-  <para>
-scsi_module.c is normally included at the end of a lower
-level driver. For it to work a declaration like this is needed before
-it is included:
-<programlisting>
-    static Scsi_Host_Template driver_template = DRIVER_TEMPLATE;
-    /* DRIVER_TEMPLATE should contain pointers to supported interface
-       functions. Scsi_Host_Template is defined hosts.h */
-    #include "scsi_module.c"
-</programlisting>
-  </para>
-  <para>
-The scsi_module.c assumes the name "driver_template" is appropriately
-defined. It contains 2 functions:
-<orderedlist>
-<listitem><para>
-     init_this_scsi_driver() called during builtin and module driver

-  </para>
-<para>
-When a new, lower level driver is being added to Linux, the following 
-files (all found in the drivers/scsi directory) will need some attention: 
-Makefile, Config.help and Config.in . It is probably best to look at what 
-an existing lower level driver does in this regard.

+Older Version	: 2.20.4.5 (scsi module), 2.20.2.5 (cmm module)
+
+1.	Added IOCTL backward compatibility.
+	Convert megaraid_mm driver to new compat_ioctl entry points.
+	I don't have easy access to hardware, so only compile tested.
+		- Signed-off-by:Andi Kleen <ak@muc.de>
+
+2.	megaraid_mbox fix: wrong order of arguments in memset()
+	That, BTW, shows why cross-builds are useful-the only indication of
+	problem had been a new warning showing up in sparse output on alpha
+	build (number of exceeding 256 got truncated).
+		- Signed-off-by: Al Viro

+
+	Greetings!
+
+	overcautious programming will kill your kernel ;)
+	ever thought about checking a spin_lock or even
+	asserting that it must be held (maybe just for
+	spinlock debugging?) ...
+
+	there are several checks present in the kernel
+	where somebody does a variation on the following:
+
+	  BUG_ON(!spin_is_locked(&some_lock));
+
+	so what's wrong about that? nothing, unless you
+	compile the code with CONFIG_DEBUG_SPINLOCK but 
+	without CONFIG_SMP ... in which case the BUG()
+	will kill your kernel ...
+
+	maybe it's not advised to make such assertions, 
+	but here is a solution which works for me ...
+	(compile tested for sh, x86_64 and x86, boot/run
+	tested for x86 only)

+README for the SCSI media changer driver
+========================================
+
+This is a driver for SCSI Medium Changer devices, which are listed
+with "Type: Medium Changer" in /proc/scsi/scsi.
+
+This is for *real* Jukeboxes.  It is *not* supported to work with
+common small CD-ROM changers, neither one-lun-per-slot SCSI changers
+nor IDE drives.
+
+Userland tools available from here:
+	http://linux.bytesex.org/misc/changer.html
+
+
+General Information
+-------------------
+
+First some words about how changers work: A changer has 2 (possibly
+more) SCSI ID's. One for the changer device which controls the robot,
+and one for the device which actually reads and writes the data. The
+later may be anything, a MOD, a CD-ROM, a tape or whatever. For the
+changer device this is a "don't care", he *only* shuffles around the
+media, nothing else.
+
+
+The SCSI changer model is complex, compared to - for example - IDE-CD
+changers. But it allows to handle nearly all possible cases. It knows
+4 different types of changer elements:
+
+  media transport - this one shuffles around the media, i.e. the
+                    transport arm.  Also known as "picker".
+  storage         - a slot which can hold a media.
+  import/export   - the same as above, but is accessable from outside,
+                    i.e. there the operator (you !) can use this to
+                    fill in and remove media from the changer.
+		    Sometimes named "mailslot".
+  data transfer   - this is the device which reads/writes, i.e. the
+		    CD-ROM / Tape / whatever drive.
+
+None of these is limited to one: A huge Jukebox could have slots for
+123 CD-ROM's, 5 CD-ROM readers (and therefore 6 SCSI ID's: the changer
+and each CD-ROM) and 2 transport arms. No problem to handle.
+
+
+How it is implemented
+---------------------
+
+I implemented the driver as character device driver with a NetBSD-like
+ioctl interface. Just grabbed NetBSD's header file and one of the
+other linux SCSI device drivers as starting point. The interface
+should be source code compatible with NetBSD. So if there is any
+software (anybody knows ???) which supports a BSDish changer driver,
+it should work with this driver too.
+
+Over time a few more ioctls where added, volume tag support for example
+wasn't covered by the NetBSD ioctl API.
+
+
+Current State
+-------------
+
+Support for more than one transport arm is not implemented yet (and
+nobody asked for it so far...).
+
+I test and use the driver myself with a 35 slot cdrom jukebox from
+Grundig.  I got some reports telling it works ok with tape autoloaders
+(Exabyte, HP and DEC).  Some People use this driver with amanda.  It
+works fine with small (11 slots) and a huge (4 MOs, 88 slots)
+magneto-optical Jukebox.  Probably with lots of other changers too, most
+(but not all :-) people mail me only if it does *not* work...
+
+I don't have any device lists, neither black-list nor white-list.  Thus
+it is quite useless to ask me whenever a specific device is supported or
+not.  In theory every changer device which supports the SCSI-2 media
+changer command set should work out-of-the-box with this driver.  If it
+doesn't, it is a bug.  Either within the driver or within the firmware
+of the changer device.
+
+
+Using it
+--------
+
+This is a character device with major number is 86, so use
+"mknod /dev/sch0 c 86 0" to create the special file for the driver.
+
+If the module finds the changer, it prints some messages about the
+device [ try "dmesg" if you don't see anything ] and should show up in
+/proc/devices. If not....  some changers use ID ? / LUN 0 for the
+device and ID ? / LUN 1 for the robot mechanism. But Linux does *not*
+look for LUN's other than 0 as default, becauce there are to many
+broken devices. So you can try:
+
+  1) echo "scsi add-single-device 0 0 ID 1" > /proc/scsi/scsi
+     (replace ID with the SCSI-ID of the device)
+  2) boot the kernel with "max_scsi_luns=1" on the command line
+     (append="max_scsi_luns=1" in lilo.conf should do the trick)
+
+
+Trouble?
+--------
+
+If you insmod the driver with "insmod debug=1", it will be verbose and
+prints a lot of stuff to the syslog.  Compiling the kernel with
+CONFIG_SCSI_CONSTANTS=y improves the quality of the error messages alot
+because the kernel will translate the error codes into human-readable
+strings then.
+
+You can display these messages with the dmesg command (or check the
+logfiles).  If you email me some question becauce of a problem with the
+driver, please include these messages.
+
+
+Insmod options
+--------------
+
+debug=0/1
+	Enable debug messages (see above, default: 0).
+
+verbose=0/1
+	Be verbose (default: 1).
+
+init=0/1
+	Send INITIALIZE ELEMENT STATUS command to the changer
+	at insmod time (default: 1).
+
+timeout_init=<seconds>
+	timeout for the INITIALIZE ELEMENT STATUS command
+	(default: 3600).
+
+timeout_move=<seconds>
+	timeout for all other commands (default: 120).
+
+dt_id=<id1>,<id2>,...
+dt_lun=<lun1>,<lun2>,...
+	These two allow to specify the SCSI ID and LUN for the data
+	transfer elements.  You likely don't need this as the jukebox
+	should provide this information.  But some devices don't ...
+
+vendor_firsts=
+vendor_counts=
+vendor_labels=
+	These insmod options can be used to tell the driver that there
+	are some vendor-specific element types.  Grundig for example
+	does this.  Some jukeboxes have a printer to label fresh burned
+	CDs, which is addressed as element 0xc000 (type 5).  To tell the
+	driver about this vendor-specific element, use this:
+		$ insmod ch			\
+			vendor_firsts=0xc000	\
+			vendor_counts=1		\
+			vendor_labels=printer
+	All three insmod options accept up to four comma-separated
+	values, this way you can configure the element types 5-8.
+	You likely need the SCSI specs for the device in question to
+	find the correct values as they are not covered by the SCSI-2
+	standard.
+
+

+	  This kernel feature is useful for number crunching applications
+	  that may need to compute untrusted bytecode during their
+	  execution. By using pipes or other transports made available to
+	  the process as file descriptors supporting the read/write
+	  syscalls, it's possible to isolate those applications in
+	  their own address space using seccomp. Once seccomp is
+	  enabled via /proc/<pid>/seccomp, it cannot be disabled
+	  and the task is only allowed to execute a few safe syscalls
+	  defined by each seccomp mode.
+
+	  If unsure, say Y. Only embedded should say N here.
