is negative. It requires explicit memory barrier semantics around the
operation.
+Then:
+
+ int atomic_cmpxchg(atomic_t *v, int old, int new);
+
+This performs an atomic compare exchange operation on the atomic value v,
+with the given old and new values. Like all atomic_xxx operations,
+atomic_cmpxchg will only satisfy its atomicity semantics as long as all
+other accesses of *v are performed through atomic_xxx operations.
+
+atomic_cmpxchg requires explicit memory barriers around the operation.
+
+The semantics for atomic_cmpxchg are the same as those defined for 'cas'
+below.
+
+Finally:
+
+ int atomic_add_unless(atomic_t *v, int a, int u);
+
+If the atomic value v is not equal to u, this function adds a to v, and
+returns non zero. If v is equal to u then it returns zero. This is done as
+an atomic operation.

If a caller requires memory barrier semantics around an atomic_t
operation which does not return a value, a set of interfaces are
defined which accomplish this:
4.4 I/O contexts
I/O contexts provide a dynamically allocated per process data area. They may
be used in I/O schedulers, and in the block layer (could be used for IO statis,
-priorities for example). See *io_context in drivers/block/ll_rw_blk.c, and
-as-iosched.c for an example of usage in an i/o scheduler.

-INTRODUCTION
-
- The USB Bluetooth driver supports any USB Bluetooth device.
- It currently works well with the Linux USB Bluetooth stack from Axis
- (available at http://developer.axis.com/software/bluetooth/ ) and
- has been rumored to work with other Linux USB Bluetooth stacks.
-
-
-CONFIGURATION
-
- Currently the driver can handle up to 256 different USB Bluetooth
- devices at once.
-
- If you are not using devfs:
- The major number that the driver uses is 216 so to use the driver,
- create the following nodes:
- mknod /dev/ttyUB0 c 216 0
- mknod /dev/ttyUB1 c 216 1
- mknod /dev/ttyUB2 c 216 2
- mknod /dev/ttyUB3 c 216 3
- .
- .
- .
- mknod /dev/ttyUB254 c 216 254
- mknod /dev/ttyUB255 c 216 255
-
- If you are using devfs:
- The devices supported by this driver will show up as
- /dev/usb/ttub/{0,1,...}
-
- When the device is connected and recognized by the driver, the driver
- will print to the system log, which node the device has been bound to.
-
-
-CONTACT:
-
- If anyone has any problems using this driver, please contact me, or
- join the Linux-USB mailing list (information on joining the mailing
- list, as well as a link to its searchable archive is at
- http://www.linux-usb.org/ )

+# Makefile for making ELF bootable images for booting on CHRP
+# using Open Firmware.
+#
+# Geert Uytterhoeven September 1997
+#
+# Based on coffboot by Paul Mackerras
+# Simplified for ppc64 by Todd Inglett
+#
+# NOTE: this code is built for 32 bit in ELF32 format even though
+# it packages a 64 bit kernel. We do this to simplify the
+# bootloader and increase compatibility with OpenFirmware.
+#
+# To this end we need to define BOOTCC, etc, as the tools
+# needed to build the 32 bit image. These are normally HOSTCC,
+# but may be a third compiler if, for example, you are cross
+# compiling from an intel box. Once the 64bit ppc gcc is
+# stable it will probably simply be a compiler switch to
+# compile for 32bit mode.
+# To make it easier to setup a cross compiler,
+# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
+# in the toplevel makefile.

- is properly shutdown, so do not be surprised if this code does not
- initially work for you. It may help to enable device hotplugging
- support. As of this writing the exact hardware interface is
- strongly in flux, so no good recommendation can be made.

-# Makefile for making ELF bootable images for booting on CHRP
-# using Open Firmware.
-#
-# Geert Uytterhoeven September 1997
-#
-# Based on coffboot by Paul Mackerras
-# Simplified for ppc64 by Todd Inglett
-#
-# NOTE: this code is built for 32 bit in ELF32 format even though
-# it packages a 64 bit kernel. We do this to simplify the
-# bootloader and increase compatibility with OpenFirmware.
-#
-# To this end we need to define BOOTCC, etc, as the tools
-# needed to build the 32 bit image. These are normally HOSTCC,
-# but may be a third compiler if, for example, you are cross
-# compiling from an intel box. Once the 64bit ppc gcc is
-# stable it will probably simply be a compiler switch to
-# compile for 32bit mode.
-# To make it easier to setup a cross compiler,
-# CROSS32_COMPILE is setup as a prefix just like CROSS_COMPILE
-# in the toplevel makefile.

+/*************************************************************************
+* CPUSaver parameters
+*
+* All CPUSaver parameters are 16-bit literals that are part of a
+* "move immediate value" instruction. By changing the value of
+* the literal in the instruction before the code is loaded, the
+* driver can change the algorithm.
+*
+* INTDELAY - This loads the dead-man timer with its inital value.
+* When this timer expires the interrupt is asserted, and the
+* timer is reset each time a new packet is received. (see
+* BUNDLEMAX below to set the limit on number of chained packets)
+* The current default is 0x600 or 1536. Experiments show that
+* the value should probably stay within the 0x200 - 0x1000.
+*
+* BUNDLEMAX -
+* This sets the maximum number of frames that will be bundled. In
+* some situations, such as the TCP windowing algorithm, it may be
+* better to limit the growth of the bundle size than let it go as
+* high as it can, because that could cause too much added latency.
+* The default is six, because this is the number of packets in the
+* default TCP window size. A value of 1 would make CPUSaver indicate
+* an interrupt for every frame received. If you do not want to put
+* a limit on the bundle size, set this value to xFFFF.
+*
+* BUNDLESMALL -
+* This contains a bit-mask describing the minimum size frame that
+* will be bundled. The default masks the lower 7 bits, which means
+* that any frame less than 128 bytes in length will not be bundled,
+* but will instead immediately generate an interrupt. This does
+* not affect the current bundle in any way. Any frame that is 128
+* bytes or large will be bundled normally. This feature is meant
+* to provide immediate indication of ACK frames in a TCP environment.
+* Customers were seeing poor performance when a machine with CPUSaver
+* enabled was sending but not receiving. The delay introduced when
+* the ACKs were received was enough to reduce total throughput, because
+* the sender would sit idle until the ACK was finally seen.
+*
+* The current default is 0xFF80, which masks out the lower 7 bits.
+* This means that any frame which is x7F (127) bytes or smaller
+* will cause an immediate interrupt. Because this value must be a
+* bit mask, there are only a few valid values that can be used. To
+* turn this feature off, the driver can write the value xFFFF to the
+* lower word of this instruction (in the same way that the other
+* parameters are used). Likewise, a value of 0xF800 (2047) would
+* cause an interrupt to be generated for every frame, because all
+* standard Ethernet frames are <= 2047 bytes in length.

+This is the contents of some of the drivers/usb/serial/ files that had old
+changelog comments. They were quite old, and out of date, and we don't keep
+them anymore, so I've put them here, away from the source files, in case
+people still care to see them.

+-----------------------------------------------------------------------
+usb-serial.h Change Log comments:
+
+ (03/26/2002) gkh
+ removed the port->tty check from port_paranoia_check() due to serial
+ consoles not having a tty device assigned to them.
+
+ (12/03/2001) gkh
+ removed active from the port structure.
+ added documentation to the usb_serial_device_type structure
+
+ (10/10/2001) gkh
+ added vendor and product to serial structure. Needed to determine device
+ owner when the device is disconnected.
+
+ (05/30/2001) gkh
+ added sem to port structure and removed port_lock
+
+ (10/05/2000) gkh
+ Added interrupt_in_endpointAddress and bulk_in_endpointAddress to help
+ fix bug with urb->dev not being set properly, now that the usb core
+ needs it.

+
+-----------------------------------------------------------------------
+usb-serial.c Change Log comments:
+
+ (12/10/2002) gkh
+ Split the ports off into their own struct device, and added a
+ usb-serial bus driver.
+
+ (11/19/2002) gkh
+ removed a few #ifdefs for the generic code and cleaned up the failure
+ logic in initialization.
+
+ (10/02/2002) gkh
+ moved the console code to console.c and out of this file.
+
+ (06/05/2002) gkh
+ moved location of startup() call in serial_probe() until after all
+ of the port information and endpoints are initialized. This makes
+ things easier for some drivers.
+
+ (04/10/2002) gkh
+ added serial_read_proc function which creates a
+ /proc/tty/driver/usb-serial file.
+
+ (03/27/2002) gkh
+ Got USB serial console code working properly and merged into the main
+ version of the tree. Thanks to Randy Dunlap for the initial version
+ of this code, and for pushing me to finish it up.
+ The USB serial console works with any usb serial driver device.
+
+ (03/21/2002) gkh
+ Moved all manipulation of port->open_count into the core. Now the
+ individual driver's open and close functions are called only when the
+ first open() and last close() is called. Making the drivers a bit
+ smaller and simpler.
+ Fixed a bug if a driver didn't have the owner field set.
+
+ (02/26/2002) gkh
+ Moved all locking into the main serial_* functions, instead of having
+ the individual drivers have to grab the port semaphore. This should
+ reduce races.
+ Reworked the MOD_INC logic a bit to always increment and decrement, even
+ if the generic driver is being used.
+
+ (10/10/2001) gkh
+ usb_serial_disconnect() now sets the serial->dev pointer is to NULL to
+ help prevent child drivers from accessing the device since it is now
+ gone.
+
+ (09/13/2001) gkh
+ Moved generic driver initialize after we have registered with the USB
+ core. Thanks to Randy Dunlap for pointing this problem out.
+
+ (07/03/2001) gkh
+ Fixed module paramater size. Thanks to John Brockmeyer for the pointer.
+ Fixed vendor and product getting defined through the MODULE_PARM macro
+ if the Generic driver wasn't compiled in.
+ Fixed problem with generic_shutdown() not being called for drivers that
+ don't have a shutdown() function.
+
+ (06/06/2001) gkh
+ added evil hack that is needed for the prolific pl2303 device due to the
+ crazy way its endpoints are set up.
+
+ (05/30/2001) gkh
+ switched from using spinlock to a semaphore, which fixes lots of problems.
+
+ (04/08/2001) gb
+ Identify version on module load.
+
+ 2001_02_05 gkh
+ Fixed buffer overflows bug with the generic serial driver. Thanks to
+ Todd Squires <squirest@ct0.com> for fixing this.
+
+ (01/10/2001) gkh
+ Fixed bug where the generic serial adaptor grabbed _any_ device that was
+ offered to it.
+
+ (12/12/2000) gkh
+ Removed MOD_INC and MOD_DEC from poll and disconnect functions, and
+ moved them to the serial_open and serial_close functions.
+ Also fixed bug with there not being a MOD_DEC for the generic driver
+ (thanks to Gary Brubaker for finding this.)
+
+ (11/29/2000) gkh
+ Small NULL pointer initialization cleanup which saves a bit of disk image
+
+ (11/01/2000) Adam J. Richter
+ instead of using idVendor/idProduct pairs, usb serial drivers
+ now identify their hardware interest with usb_device_id tables,
+ which they usually have anyhow for use with MODULE_DEVICE_TABLE.
+
+ (10/05/2000) gkh
+ Fixed bug with urb->dev not being set properly, now that the usb
+ core needs it.
+
+ (09/11/2000) gkh
+ Removed DEBUG #ifdefs with call to usb_serial_debug_data
+
+ (08/28/2000) gkh
+ Added port_lock to port structure.
+ Added locks for SMP safeness to generic driver
+ Fixed the ability to open a generic device's port more than once.
+
+ (07/23/2000) gkh
+ Added bulk_out_endpointAddress to port structure.
+
+ (07/19/2000) gkh, pberger, and borchers
+ Modifications to allow usb-serial drivers to be modules.
+
+ (07/03/2000) gkh
+ Added more debugging to serial_ioctl call
+
+ (06/25/2000) gkh
+ Changed generic_write_bulk_callback to not call wake_up_interruptible
+ directly, but to have port_softint do it at a safer time.
+
+ (06/23/2000) gkh
+ Cleaned up debugging statements in a quest to find UHCI timeout bug.
+
+ (05/22/2000) gkh
+ Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be
+ removed from the individual device source files.
+
+ (05/03/2000) gkh
+ Added the Digi Acceleport driver from Al Borchers and Peter Berger.
+
+ (05/02/2000) gkh
+ Changed devfs and tty register code to work properly now. This was based on
+ the ACM driver changes by Vojtech Pavlik.
+
+ (04/27/2000) Ryan VanderBijl
+ Put calls to *_paranoia_checks into one function.
+
+ (04/23/2000) gkh
+ Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.
+ Moved when the startup code printed out the devices that are supported.
+
+ (04/19/2000) gkh
+ Added driver for ZyXEL omni.net lcd plus ISDN TA
+ Made startup info message specify which drivers were compiled in.
+
+ (04/03/2000) gkh
+ Changed the probe process to remove the module unload races.
+ Changed where the tty layer gets initialized to have devfs work nicer.
+ Added initial devfs support.
+
+ (03/26/2000) gkh
+ Split driver up into device specific pieces.
+
+ (03/19/2000) gkh
+ Fixed oops that could happen when device was removed while a program
+ was talking to the device.
+ Removed the static urbs and now all urbs are created and destroyed
+ dynamically.
+ Reworked the internal interface. Now everything is based on the
+ usb_serial_port structure instead of the larger usb_serial structure.
+ This fixes the bug that a multiport device could not have more than
+ one port open at one time.
+
+ (03/17/2000) gkh
+ Added config option for debugging messages.
+ Added patch for keyspan pda from Brian Warner.
+
+ (03/06/2000) gkh
+ Added the keyspan pda code from Brian Warner <warner@lothar.com>
+ Moved a bunch of the port specific stuff into its own structure. This
+ is in anticipation of the true multiport devices (there's a bug if you
+ try to access more than one port of any multiport device right now)
+
+ (02/21/2000) gkh
+ Made it so that any serial devices only have to specify which functions
+ they want to overload from the generic function calls (great,
+ inheritance in C, in a driver, just what I wanted...)
+ Added support for set_termios and ioctl function calls. No drivers take
+ advantage of this yet.
+ Removed the #ifdef MODULE, now there is no module specific code.
+ Cleaned up a few comments in usb-serial.h that were wrong (thanks again
+ to Miles Lott).
+ Small fix to get_free_serial.
+
+ (02/14/2000) gkh
+ Removed the Belkin and Peracom functionality from the driver due to
+ the lack of support from the vendor, and me not wanting people to
+ accidenatly buy the device, expecting it to work with Linux.
+ Added read_bulk_callback and write_bulk_callback to the type structure
+ for the needs of the FTDI and WhiteHEAT driver.
+ Changed all reverences to FTDI to FTDI_SIO at the request of Bill
+ Ryder.
+ Changed the output urb size back to the max endpoint size to make
+ the ftdi_sio driver have it easier, and due to the fact that it didn't
+ really increase the speed any.
+
+ (02/11/2000) gkh
+ Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a
+ patch from Miles Lott (milos@insync.net).
+ Fixed bug with not restoring the minor range that a device grabs, if
+ the startup function fails (thanks Miles for finding this).
+
+ (02/05/2000) gkh
+ Added initial framework for the Keyspan PDA serial converter so that
+ Brian Warner has a place to put his code.
+ Made the ezusb specific functions generic enough that different
+ devices can use them (whiteheat and keyspan_pda both need them).
+ Split out a whole bunch of structure and other stuff to a separate
+ usb-serial.h file.
+ Made the Visor connection messages a little more understandable, now
+ that Miles Lott (milos@insync.net) has gotten the Generic channel to
+ work. Also made them always show up in the log file.
+
+ (01/25/2000) gkh
+ Added initial framework for FTDI serial converter so that Bill Ryder
+ has a place to put his code.
+ Added the vendor specific info from Handspring. Now we can print out
+ informational debug messages as well as understand what is happening.
+
+ (01/23/2000) gkh
+ Fixed problem of crash when trying to open a port that didn't have a
+ device assigned to it. Made the minor node finding a little smarter,
+ now it looks to find a continuous space for the new device.
+
+ (01/21/2000) gkh
+ Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net)
+ Fixed get_serial_by_minor which was all messed up for multi port
+ devices. Fixed multi port problem for generic devices. Now the number
+ of ports is determined by the number of bulk out endpoints for the
+ generic device.
+
+ (01/19/2000) gkh
+ Removed lots of cruft that was around from the old (pre urb) driver
+ interface.
+ Made the serial_table dynamic. This should save lots of memory when
+ the number of minor nodes goes up to 256.
+ Added initial support for devices that have more than one port.
+ Added more debugging comments for the Visor, and added a needed
+ set_configuration call.
+
+ (01/17/2000) gkh
+ Fixed the WhiteHEAT firmware (my processing tool had a bug)
+ and added new debug loader firmware for it.
+ Removed the put_char function as it isn't really needed.
+ Added visor startup commands as found by the Win98 dump.
+
+ (01/13/2000) gkh
+ Fixed the vendor id for the generic driver to the one I meant it to be.
+
+ (01/12/2000) gkh
+ Forget the version numbering...that's pretty useless...
+ Made the driver able to be compiled so that the user can select which
+ converter they want to use. This allows people who only want the Visor
+ support to not pay the memory size price of the WhiteHEAT.
+ Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)
+ grabbed the root hub. Not good.
+
+ version 0.4.0 (01/10/2000) gkh
+ Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT
+ device. Added startup function to allow firmware to be downloaded to
+ a device if it needs to be.
+ Added firmware download logic to the WhiteHEAT device.
+ Started to add #defines to split up the different drivers for potential
+ configuration option.
+
+ version 0.3.1 (12/30/99) gkh
+ Fixed problems with urb for bulk out.
+ Added initial support for multiple sets of endpoints. This enables
+ the Handspring Visor to be attached successfully. Only the first
+ bulk in / bulk out endpoint pair is being used right now.
+
+ version 0.3.0 (12/27/99) gkh
+ Added initial support for the Handspring Visor based on a patch from
+ Miles Lott (milos@sneety.insync.net)
+ Cleaned up the code a bunch and converted over to using urbs only.
+
+ version 0.2.3 (12/21/99) gkh
+ Added initial support for the Connect Tech WhiteHEAT converter.
+ Incremented the number of ports in expectation of getting the
+ WhiteHEAT to work properly (4 ports per connection).
+ Added notification on insertion and removal of what port the
+ device is/was connected to (and what kind of device it was).
+
+ version 0.2.2 (12/16/99) gkh
+ Changed major number to the new allocated number. We're legal now!
+
+ version 0.2.1 (12/14/99) gkh
+ Fixed bug that happens when device node is opened when there isn't a
+ device attached to it. Thanks to marek@webdesign.no for noticing this.
+
+ version 0.2.0 (11/10/99) gkh
+ Split up internals to make it easier to add different types of serial
+ converters to the code.
+ Added a "generic" driver that gets it's vendor and product id
+ from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net)
+ for the idea and sample code (from the usb scanner driver.)
+ Cleared up any licensing questions by releasing it under the GNU GPL.
+
+ version 0.1.2 (10/25/99) gkh
+ Fixed bug in detecting device.
+
+ version 0.1.1 (10/05/99) gkh
+ Changed the major number to not conflict with anything else.
+
+ version 0.1 (09/28/99) gkh
+ Can recognize the two different devices and start up a read from
+ device when asked to. Writes also work. No control signals yet, this
+ all is vendor specific data (i.e. no spec), also no control for
+ different baud rates or other bit settings.
+ Currently we are using the same devid as the acm driver. This needs
+ to change.
+
+-----------------------------------------------------------------------
+visor.c Change Log comments:
+

+ Added support for module parameter options for untested/unknown
+ devices.

+
+ (03/27/2002) gkh

+ for usb serial console devices.)
+
+ (03/23/2002) gkh
+ Added support for the Palm i705 device, thanks to Thomas Riemer
+ <tom@netmech.com> for the information.
+
+ (03/21/2002) gkh
+ Added support for the Palm m130 device, thanks to Udo Eisenbarth
+ <udo.eisenbarth@web.de> for the information.
+
+ (02/27/2002) gkh
+ Reworked the urb handling logic. We have no more pool, but dynamically
+ allocate the urb and the transfer buffer on the fly. In testing this
+ does not incure any measurable overhead. This also relies on the fact
+ that we have proper reference counting logic for urbs.
+
+ (02/21/2002) SilaS
+ Added initial support for the Palm m515 devices.
+
+ (02/14/2002) gkh
+ Added support for the Clie S-360 device.
+

+ (08/30/2001) gkh
+ Added support for the Clie devices, both the 3.5 and 4.0 os versions.
+ Many thanks to Daniel Burke, and Bryan Payne for helping with this.
+
+ (08/23/2001) gkh
+ fixed a few potential bugs pointed out by Oliver Neukum.
+
+ (05/30/2001) gkh
+ switched from using spinlock to a semaphore, which fixes lots of problems.
+
+ (05/28/2000) gkh
+ Added initial support for the Palm m500 and Palm m505 devices.
+
+ (04/08/2001) gb
+ Identify version on module load.
+
+ (01/21/2000) gkh
+ Added write_room and chars_in_buffer, as they were previously using the
+ generic driver versions which is all wrong now that we are using an urb
+ pool. Thanks to Wolfgang Grandegger for pointing this out to me.
+ Removed count assignment in the write function, which was not needed anymore
+ either. Thanks to Al Borchers for pointing this out.
+
+ (12/12/2000) gkh
+ Moved MOD_DEC to end of visor_close to be nicer, as the final write
+ message can sleep.
+
+ (11/12/2000) gkh
+ Fixed bug with data being dropped on the floor by forcing tty->low_latency
+ to be on. Hopefully this fixes the OHCI issue!
+
+ (11/01/2000) Adam J. Richter
+ usb_device_id table support
+
+ (10/05/2000) gkh
+ Fixed bug with urb->dev not being set properly, now that the usb
+ core needs it.
+
+ (09/11/2000) gkh
+ Got rid of always calling kmalloc for every urb we wrote out to the
+ device.
+ Added visor_read_callback so we can keep track of bytes in and out for
+ those people who like to know the speed of their device.
+ Removed DEBUG #ifdefs with call to usb_serial_debug_data
+
+ (09/06/2000) gkh
+ Fixed oops in visor_exit. Need to uncomment usb_unlink_urb call _after_
+ the host controller drivers set urb->dev = NULL when the urb is finished.
+
+ (08/28/2000) gkh
+ Added locks for SMP safeness.
+
+ (08/08/2000) gkh
+ Fixed endian problem in visor_startup.
+ Fixed MOD_INC and MOD_DEC logic and the ability to open a port more
+ than once.
+
+ (07/23/2000) gkh
+ Added pool of write urbs to speed up transfers to the visor.
+
+ (07/19/2000) gkh
+ Added module_init and module_exit functions to handle the fact that this
+ driver is a loadable module now.
+
+ (07/03/2000) gkh
+ Added visor_set_ioctl and visor_set_termios functions (they don't do much
+ of anything, but are good for debugging.)
+
+ (06/25/2000) gkh
+ Fixed bug in visor_unthrottle that should help with the disconnect in PPP
+ bug that people have been reporting.
+
+ (06/23/2000) gkh
+ Cleaned up debugging statements in a quest to find UHCI timeout bug.
+
+ (04/27/2000) Ryan VanderBijl
+ Fixed memory leak in visor_close
+
+ (03/26/2000) gkh
+ Split driver up into device specific pieces.
+
+-----------------------------------------------------------------------
+pl2303.c Change Log comments:
+
+ 2002_Mar_26 gkh
+ allowed driver to work properly if there is no tty assigned to a port
+ (this happens for serial console devices.)
+
+ 2001_Oct_06 gkh
+ Added RTS and DTR line control. Thanks to joe@bndlg.de for parts of it.
+
+ 2001_Sep_19 gkh
+ Added break support.
+
+ 2001_Aug_30 gkh
+ fixed oops in write_bulk_callback.
+
+ 2001_Aug_28 gkh
+ reworked buffer logic to be like other usb-serial drivers. Hopefully

------------------------------------------------------------------------
-usb-serial.c Change Log comments:
-
- (12/10/2002) gkh
- Split the ports off into their own struct device, and added a
- usb-serial bus driver.
-
- (11/19/2002) gkh
- removed a few #ifdefs for the generic code and cleaned up the failure
- logic in initialization.
-
- (10/02/2002) gkh
- moved the console code to console.c and out of this file.
-
- (06/05/2002) gkh
- moved location of startup() call in serial_probe() until after all
- of the port information and endpoints are initialized. This makes
- things easier for some drivers.
-
- (04/10/2002) gkh
- added serial_read_proc function which creates a
- /proc/tty/driver/usb-serial file.
-
- (03/27/2002) gkh
- Got USB serial console code working properly and merged into the main
- version of the tree. Thanks to Randy Dunlap for the initial version
- of this code, and for pushing me to finish it up.
- The USB serial console works with any usb serial driver device.
-
- (03/21/2002) gkh
- Moved all manipulation of port->open_count into the core. Now the
- individual driver's open and close functions are called only when the
- first open() and last close() is called. Making the drivers a bit
- smaller and simpler.
- Fixed a bug if a driver didn't have the owner field set.
-
- (02/26/2002) gkh
- Moved all locking into the main serial_* functions, instead of having
- the individual drivers have to grab the port semaphore. This should
- reduce races.
- Reworked the MOD_INC logic a bit to always increment and decrement, even
- if the generic driver is being used.
-
- (10/10/2001) gkh
- usb_serial_disconnect() now sets the serial->dev pointer is to NULL to
- help prevent child drivers from accessing the device since it is now
- gone.
-
- (09/13/2001) gkh
- Moved generic driver initialize after we have registered with the USB
- core. Thanks to Randy Dunlap for pointing this problem out.
-
- (07/03/2001) gkh
- Fixed module paramater size. Thanks to John Brockmeyer for the pointer.
- Fixed vendor and product getting defined through the MODULE_PARM macro
- if the Generic driver wasn't compiled in.
- Fixed problem with generic_shutdown() not being called for drivers that
- don't have a shutdown() function.
-
- (06/06/2001) gkh
- added evil hack that is needed for the prolific pl2303 device due to the
- crazy way its endpoints are set up.
-
- (05/30/2001) gkh
- switched from using spinlock to a semaphore, which fixes lots of problems.
-
- (04/08/2001) gb
- Identify version on module load.
-
- 2001_02_05 gkh
- Fixed buffer overflows bug with the generic serial driver. Thanks to
- Todd Squires <squirest@ct0.com> for fixing this.
-
- (01/10/2001) gkh
- Fixed bug where the generic serial adaptor grabbed _any_ device that was
- offered to it.
-
- (12/12/2000) gkh
- Removed MOD_INC and MOD_DEC from poll and disconnect functions, and
- moved them to the serial_open and serial_close functions.
- Also fixed bug with there not being a MOD_DEC for the generic driver
- (thanks to Gary Brubaker for finding this.)
-
- (11/29/2000) gkh
- Small NULL pointer initialization cleanup which saves a bit of disk image
-
- (11/01/2000) Adam J. Richter
- instead of using idVendor/idProduct pairs, usb serial drivers
- now identify their hardware interest with usb_device_id tables,
- which they usually have anyhow for use with MODULE_DEVICE_TABLE.
-
- (10/05/2000) gkh
- Fixed bug with urb->dev not being set properly, now that the usb
- core needs it.
-
- (09/11/2000) gkh

- Added bulk_out_endpointAddress to port structure.
-
- (07/19/2000) gkh, pberger, and borchers

-
- (07/03/2000) gkh
- Added more debugging to serial_ioctl call
-
- (06/25/2000) gkh
- Changed generic_write_bulk_callback to not call wake_up_interruptible
- directly, but to have port_softint do it at a safer time.
-
- (06/23/2000) gkh
- Cleaned up debugging statements in a quest to find UHCI timeout bug.
-
- (05/22/2000) gkh
- Changed the makefile, enabling the big CONFIG_USB_SERIAL_SOMTHING to be
- removed from the individual device source files.
-
- (05/03/2000) gkh
- Added the Digi Acceleport driver from Al Borchers and Peter Berger.
-
- (05/02/2000) gkh
- Changed devfs and tty register code to work properly now. This was based on
- the ACM driver changes by Vojtech Pavlik.
-
- (04/27/2000) Ryan VanderBijl
- Put calls to *_paranoia_checks into one function.
-
- (04/23/2000) gkh
- Fixed bug that Randy Dunlap found for Generic devices with no bulk out ports.
- Moved when the startup code printed out the devices that are supported.
-
- (04/19/2000) gkh
- Added driver for ZyXEL omni.net lcd plus ISDN TA
- Made startup info message specify which drivers were compiled in.
-
- (04/03/2000) gkh
- Changed the probe process to remove the module unload races.
- Changed where the tty layer gets initialized to have devfs work nicer.
- Added initial devfs support.
-
- (03/26/2000) gkh
- Split driver up into device specific pieces.
-
- (03/19/2000) gkh
- Fixed oops that could happen when device was removed while a program
- was talking to the device.
- Removed the static urbs and now all urbs are created and destroyed
- dynamically.
- Reworked the internal interface. Now everything is based on the
- usb_serial_port structure instead of the larger usb_serial structure.
- This fixes the bug that a multiport device could not have more than
- one port open at one time.
-
- (03/17/2000) gkh
- Added config option for debugging messages.
- Added patch for keyspan pda from Brian Warner.
-
- (03/06/2000) gkh
- Added the keyspan pda code from Brian Warner <warner@lothar.com>
- Moved a bunch of the port specific stuff into its own structure. This
- is in anticipation of the true multiport devices (there's a bug if you
- try to access more than one port of any multiport device right now)
-
- (02/21/2000) gkh
- Made it so that any serial devices only have to specify which functions
- they want to overload from the generic function calls (great,
- inheritance in C, in a driver, just what I wanted...)
- Added support for set_termios and ioctl function calls. No drivers take
- advantage of this yet.
- Removed the #ifdef MODULE, now there is no module specific code.
- Cleaned up a few comments in usb-serial.h that were wrong (thanks again
- to Miles Lott).
- Small fix to get_free_serial.
-
- (02/14/2000) gkh
- Removed the Belkin and Peracom functionality from the driver due to
- the lack of support from the vendor, and me not wanting people to
- accidenatly buy the device, expecting it to work with Linux.
- Added read_bulk_callback and write_bulk_callback to the type structure
- for the needs of the FTDI and WhiteHEAT driver.
- Changed all reverences to FTDI to FTDI_SIO at the request of Bill
- Ryder.
- Changed the output urb size back to the max endpoint size to make
- the ftdi_sio driver have it easier, and due to the fact that it didn't
- really increase the speed any.
-
- (02/11/2000) gkh
- Added VISOR_FUNCTION_CONSOLE to the visor startup function. This was a
- patch from Miles Lott (milos@insync.net).
- Fixed bug with not restoring the minor range that a device grabs, if
- the startup function fails (thanks Miles for finding this).
-
- (02/05/2000) gkh
- Added initial framework for the Keyspan PDA serial converter so that
- Brian Warner has a place to put his code.
- Made the ezusb specific functions generic enough that different
- devices can use them (whiteheat and keyspan_pda both need them).
- Split out a whole bunch of structure and other stuff to a separate
- usb-serial.h file.
- Made the Visor connection messages a little more understandable, now
- that Miles Lott (milos@insync.net) has gotten the Generic channel to
- work. Also made them always show up in the log file.
-
- (01/25/2000) gkh
- Added initial framework for FTDI serial converter so that Bill Ryder
- has a place to put his code.
- Added the vendor specific info from Handspring. Now we can print out
- informational debug messages as well as understand what is happening.
-
- (01/23/2000) gkh
- Fixed problem of crash when trying to open a port that didn't have a
- device assigned to it. Made the minor node finding a little smarter,
- now it looks to find a continuous space for the new device.
-
- (01/21/2000) gkh
- Fixed bug in visor_startup with patch from Miles Lott (milos@insync.net)
- Fixed get_serial_by_minor which was all messed up for multi port
- devices. Fixed multi port problem for generic devices. Now the number
- of ports is determined by the number of bulk out endpoints for the
- generic device.
-
- (01/19/2000) gkh
- Removed lots of cruft that was around from the old (pre urb) driver
- interface.
- Made the serial_table dynamic. This should save lots of memory when
- the number of minor nodes goes up to 256.
- Added initial support for devices that have more than one port.
- Added more debugging comments for the Visor, and added a needed
- set_configuration call.
-
- (01/17/2000) gkh
- Fixed the WhiteHEAT firmware (my processing tool had a bug)
- and added new debug loader firmware for it.
- Removed the put_char function as it isn't really needed.
- Added visor startup commands as found by the Win98 dump.
-
- (01/13/2000) gkh
- Fixed the vendor id for the generic driver to the one I meant it to be.
-
- (01/12/2000) gkh
- Forget the version numbering...that's pretty useless...
- Made the driver able to be compiled so that the user can select which
- converter they want to use. This allows people who only want the Visor
- support to not pay the memory size price of the WhiteHEAT.
- Fixed bug where the generic driver (idVendor=0000 and idProduct=0000)
- grabbed the root hub. Not good.
-
- version 0.4.0 (01/10/2000) gkh
- Added whiteheat.h containing the firmware for the ConnectTech WhiteHEAT
- device. Added startup function to allow firmware to be downloaded to
- a device if it needs to be.
- Added firmware download logic to the WhiteHEAT device.
- Started to add #defines to split up the different drivers for potential
- configuration option.
-
- version 0.3.1 (12/30/99) gkh
- Fixed problems with urb for bulk out.
- Added initial support for multiple sets of endpoints. This enables
- the Handspring Visor to be attached successfully. Only the first
- bulk in / bulk out endpoint pair is being used right now.
-
- version 0.3.0 (12/27/99) gkh
- Added initial support for the Handspring Visor based on a patch from
- Miles Lott (milos@sneety.insync.net)
- Cleaned up the code a bunch and converted over to using urbs only.
-
- version 0.2.3 (12/21/99) gkh
- Added initial support for the Connect Tech WhiteHEAT converter.
- Incremented the number of ports in expectation of getting the
- WhiteHEAT to work properly (4 ports per connection).
- Added notification on insertion and removal of what port the
- device is/was connected to (and what kind of device it was).
-
- version 0.2.2 (12/16/99) gkh
- Changed major number to the new allocated number. We're legal now!
-
- version 0.2.1 (12/14/99) gkh
- Fixed bug that happens when device node is opened when there isn't a
- device attached to it. Thanks to marek@webdesign.no for noticing this.
-
- version 0.2.0 (11/10/99) gkh
- Split up internals to make it easier to add different types of serial
- converters to the code.
- Added a "generic" driver that gets it's vendor and product id
- from when the module is loaded. Thanks to David E. Nelson (dnelson@jump.net)
- for the idea and sample code (from the usb scanner driver.)
- Cleared up any licensing questions by releasing it under the GNU GPL.
-
- version 0.1.2 (10/25/99) gkh
- Fixed bug in detecting device.
-
- version 0.1.1 (10/05/99) gkh
- Changed the major number to not conflict with anything else.
-
- version 0.1 (09/28/99) gkh
- Can recognize the two different devices and start up a read from
- device when asked to. Writes also work. No control signals yet, this
- all is vendor specific data (i.e. no spec), also no control for
- different baud rates or other bit settings.
- Currently we are using the same devid as the acm driver. This needs
- to change.

- (02/27/2002) gkh
- Reworked the urb handling logic. We have no more pool, but dynamically
- allocate the urb and the transfer buffer on the fly. In testing this

- that we have proper reference counting logic for urbs.
-
- (02/21/2002) SilaS

- Identify version on module load.
-
- (01/21/2000) gkh
- Added write_room and chars_in_buffer, as they were previously using the
- generic driver versions which is all wrong now that we are using an urb
- pool. Thanks to Wolfgang Grandegger for pointing this out to me.
- Removed count assignment in the write function, which was not needed anymore
- either. Thanks to Al Borchers for pointing this out.
-
- (12/12/2000) gkh
- Moved MOD_DEC to end of visor_close to be nicer, as the final write
- message can sleep.
-
- (11/12/2000) gkh
- Fixed bug with data being dropped on the floor by forcing tty->low_latency
- to be on. Hopefully this fixes the OHCI issue!
-
- (11/01/2000) Adam J. Richter
- usb_device_id table support
-
- (10/05/2000) gkh
- Fixed bug with urb->dev not being set properly, now that the usb
- core needs it.
-
- (09/11/2000) gkh
- Got rid of always calling kmalloc for every urb we wrote out to the
- device.
- Added visor_read_callback so we can keep track of bytes in and out for
- those people who like to know the speed of their device.
- Removed DEBUG #ifdefs with call to usb_serial_debug_data
-
- (09/06/2000) gkh

- the host controller drivers set urb->dev = NULL when the urb is finished.
-
- (08/28/2000) gkh
- Added locks for SMP safeness.
-
- (08/08/2000) gkh

- green light starts to blink. Open port works, and data can be sent
- and received at the default settings of the UART. Loopback connector
- and debug log confirms this.
-
- 0.1 (01/23/2000) greg kroah-hartman
- Initial release to help IO Networks try to set up their test system.
- Edgeport4 is recognized, firmware is downloaded, config is set so
- device blinks green light every 3 sec. Port is bound, but opening,
- closing, and sending data do not work properly.

- * Memory barrier.
- * The sync instruction guarantees that all memory accesses initiated
- * by this processor have been performed (with respect to all other
- * mechanisms that access memory). The eieio instruction is a barrier
- * providing an ordering (separately) for (a) cacheable stores and (b)
- * loads and stores to non-cacheable memory (e.g. I/O devices).
- *
- * mb() prevents loads and stores being reordered across this point.
- * rmb() prevents loads being reordered across this point.
- * wmb() prevents stores being reordered across this point.
- * read_barrier_depends() prevents data-dependent loads being reordered
- * across this point (nop on PPC).
- *
- * We have to use the sync instructions for mb(), since lwsync doesn't
- * order loads with respect to previous stores. Lwsync is fine for
- * rmb(), though.
- * For wmb(), we use sync since wmb is used in drivers to order
- * stores to system memory with respect to writes to the device.
- * However, smp_wmb() can be a lighter-weight eieio barrier on
- * SMP since it is only used to order updates to system memory.

-/* rwsem.h: R/W semaphores implemented using XADD/CMPXCHG for x86_64+
- *
- * Written by David Howells (dhowells@redhat.com).
- * Ported by Andi Kleen <ak@suse.de> to x86-64.
- *
- * Derived from asm-i386/semaphore.h and asm-i386/rwsem.h
- *
- *
- * The MSW of the count is the negated number of active writers and waiting
- * lockers, and the LSW is the total number of active locks
- *
- * The lock count is initialized to 0 (no active and no waiting lockers).
- *
- * When a writer subtracts WRITE_BIAS, it'll get 0xffff0001 for the case of an
- * uncontended lock. This can be determined because XADD returns the old value.
- * Readers increment by 1 and see a positive value when uncontended, negative
- * if there are writers (and maybe) readers waiting (in which case it goes to
- * sleep).
- *
- * The value of WAITING_BIAS supports up to 32766 waiting processes. This can
- * be extended to 65534 by manually checking the whole MSW rather than relying
- * on the S flag.
- *
- * The value of ACTIVE_BIAS supports up to 65535 active processes.
- *
- * This should be totally fair - if anything is waiting, a process that wants a
- * lock will go to the back of the queue. When the currently active lock is
- * released, if there's a writer at the front of the queue, then that and only
- * that will be woken up; if there's a bunch of consecutive readers at the
- * front, then they'll all be woken up, but no other readers will be.
