They were quite old, and out of date, and we don't keep -them anymore, so I've put them here, away from the source files, in case -people still care to see them. - -- Greg Kroah-Hartman <greg@kroah.com> October 20, 2005 - ------------------------------------------------------------------------ -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. - - (09/11/2000) gkh - Added usb_serial_debug_data function to help get rid of #DEBUG in the - drivers. - - (08/28/2000) gkh - Added port_lock to port structure. - - (08/08/2000) gkh - Added open_count to port structure. - - (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. - ------------------------------------------------------------------------ -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.

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: - - (06/03/2003) Judd Montgomery <judd at jpilot.org> - Added support for module parameter options for untested/unknown - devices. - - (03/09/2003) gkh - Added support for the Sony Clie NZ90V device.

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.

Note: the USB-2 supports 3 devices: two -* serial and a parallel port. The parallel port is implemented -* as a serial-to-parallel converter. That is, the driver actually -* presents all three USB-2 interfaces as serial ports, but the third -* one physically connects to a parallel device. Thus, for example, -* one could plug a parallel printer into the USB-2's third port, -* but from the kernel's (and userland's) point of view what's -* actually out there is a serial device. -* -* (7/15/2000) borchers -* -- Fixed race in open when a close is in progress. -* -- Keep count of opens and dec the module use count for each -* outstanding open when shutdown is called (on disconnect). -* -- Fixed sanity checks in read_bulk_callback and write_bulk_callback -* so pointers are checked before use. -* -- Split read bulk callback into in band and out of band -* callbacks, and no longer restart read chains if there is -* a status error or a sanity error.

This eliminates -* the race condition where the wake up could happen after -* the unlock and before the sleep. -* -- Close now waits for output to drain. -* -- Open waits until any close in progress is finished. -* -- All out of band responses are now processed, not just the -* first in a USB packet. -* -- Fixed a bug that prevented the driver from working when the -* first Digi port was not the first USB serial port--the driver -* was mistakenly using the external USB serial port number to -* try to index into its internal ports. -* -- Fixed an SMP bug -- write_bulk_callback is called directly from -* an interrupt, so spin_lock_irqsave/spin_unlock_irqrestore are -* needed for locks outside write_bulk_callback that are also -* acquired by write_bulk_callback to prevent deadlocks. -* -- Fixed support for select() by making digi_chars_in_buffer() -* return 256 when -EINPROGRESS is set, as the line discipline -* code in n_tty.c expects. -* -- Fixed an include file ordering problem that prevented debugging -* messages from working. -* -- Fixed an intermittent timeout problem that caused writes to -* sometimes get stuck on some machines on some kernels. It turns -* out in these circumstances write_chan() (in n_tty.c) was -* asleep waiting for our wakeup call. Even though we call -* wake_up_interruptible() in digi_write_bulk_callback(), there is -* a race condition that could cause the wakeup to fail: if our -* wake_up_interruptible() call occurs between the time that our -* driver write routine finishes and write_chan() sets current->state -* to TASK_INTERRUPTIBLE, the effect of our wakeup setting the state -* to TASK_RUNNING will be lost and write_chan's subsequent call to -* schedule() will never return (unless it catches a signal). -* This race condition occurs because write_bulk_callback() (and thus -* the wakeup) are called asynchronously from an interrupt, rather than -* from the scheduler. We can avoid the race by calling the wakeup -* from the scheduler queue and that's our fix: Now, at the end of -* write_bulk_callback() we queue up a wakeup call on the scheduler -* task queue. We still also invoke the wakeup directly since that -* squeezes a bit more performance out of the driver, and any lost -* race conditions will get cleaned up at the next scheduler run. -* -* NOTE: The problem also goes away if you comment out -* the two code lines in write_chan() where current->state -* is set to TASK_RUNNING just before calling driver.write() and to -* TASK_INTERRUPTIBLE immediately afterwards. This is why the -* problem did not show up with the 2.2 kernels -- they do not -* include that code. -* -* (5/16/2000) pberger and borchers -* -- Added timeouts to sleeps, to defend against lost wake ups. -* -- Handle transition to/from B0 baud rate in digi_set_termios. -* -* (5/13/2000) pberger and borchers -* -- All commands now sent on out of band port, using -* digi_write_oob_command. -* -- Get modem control signals whenever they change, support TIOCMGET/ -* SET/BIS/BIC ioctls. -* -- digi_set_termios now supports parity, word size, stop bits, and -* receive enable. -* -- Cleaned up open and close, use digi_set_termios and -* digi_write_oob_command to set port parameters. -* -- Added digi_startup_device to start read chains on all ports. -* -- Write buffer is only used when count==1, to be sure put_char can -* write a char (unless the buffer is full). -* -* (5/10/2000) pberger and borchers -* -- Added MOD_INC_USE_COUNT/MOD_DEC_USE_COUNT calls on open/close. -* -- Fixed problem where the first incoming character is lost on -* port opens after the first close on that port. Now we keep -* the read_urb chain open until shutdown. -* -- Added more port conditioning calls in digi_open and digi_close. -* -- Convert port->active to a use count so that we can deal with multiple -* opens and closes properly. -* -- Fixed some problems with the locking code. -* -* (5/3/2000) pberger and borchers -* -- First alpha version of the driver--many known limitations and bugs. -* -* -* Locking and SMP -* -* - Each port, including the out-of-band port, has a lock used to -* serialize all access to the port's private structure. -* - The port lock is also used to serialize all writes and access to -* the port's URB. -* - The port lock is also used for the port write_wait condition -* variable. Holding the port lock will prevent a wake up on the -* port's write_wait; this can be used with cond_wait_... to be sure -* the wake up is not lost in a race when dropping the lock and -* sleeping waiting for the wakeup. -* - digi_write() does not sleep, since it is sometimes called on -* interrupt time. -* - digi_write_bulk_callback() and digi_read_bulk_callback() are -* called directly from interrupts. Hence spin_lock_irqsave() -* and spin_unlock_irqrestore() are used in the rest of the code -* for any locks they acquire. -* - digi_write_bulk_callback() gets the port lock before waking up -* processes sleeping on the port write_wait. It also schedules -* wake ups so they happen from the scheduler, because the tty -* system can miss wake ups from interrupts. -* - All sleeps use a timeout of DIGI_RETRY_TIMEOUT before looping to -* recheck the condition they are sleeping on. This is defensive, -* in case a wake up is lost. -* - Following Documentation/DocBook/kernel-locking.tmpl no spin locks -* are held when calling copy_to/from_user or printk. */ #include <linux/kernel.h> @@ -467,7 +251,7 @@ static int digi_read_oob_callback(struct urb *urb);
