* USB: remove references to port->port.count from the serial driversAlan Stern2010-03-021-4/+4
| | | | | | | | | | | | This patch (as1344) removes references to port->port.count from the USB serial drivers. Now that serial ports are properly reference counted, port.count checking is unnecessary and incorrect. Drivers should assume that the port is in use from the time the open method runs until the close method is called.

* USB: serial: sierra driver indat_callback fixElina Pasheva2010-03-021-8/+11
| | | | | | | | | | | | | | | | | | | A crash has been reported with sierra driver on disconnect with Ubuntu/Lucid distribution based on kernel-2.6.32. The cause of the crash was determined as "NULL tty pointer was being referenced" and the NULL pointer was passed by sierra_indat_callback(). This patch modifies sierra_indat_callback() function to check for NULL tty structure pointer. This modification prevents a crash from happening when the device is disconnected.

* USB: serial: sierra driver memory reductionElina Pasheva2009-12-111-12/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch deals with reducing the memory footprint for sierra driver. This optimization is aimed for embedded software customers. Some sierra modems can expose upwards of 7 USB interfaces, each possibly offering different services. In general, interfaces used for the exchange of wireless data require much higher throughput, hence require more memory (i.e. more URBs) than lower performance interfaces. URBs used for the IN direction are pre-allocated by the driver and this patch introduces a way to configure the number of IN URBs allocated on a per-interface basis. Interfaces with lower throughput requirements receive fewer URBs, thereby reducing the RAM memory consumed by the driver. NOTE1: This driver has always pre-allocated URBs for the IN direction. NOTE2: The number of URBs pre-allocated for the low-performance interfaces has already been extensively tested in previous versions of this driver. We also added the capability to log function calls by adding DEBUG flag. Please note that this flag is commented out because this is the default state for it.

| | | | | | | | | | | | | | | | | | | | | This patch presents fixes for the autosuspend feature implementation in sierra usb serial driver in functions sierra_open(), sierra_close() and stop_read_write_urbs(). The patch "sierra_close() must resume the device before it notifies it of a closure" submitted by Oliver Neukum on Wed, October 14 has been merged as fix in sierra_close() function. The bug fix in sierra_open() function restores the autopm interface state on error condition.

| | | | | | | | | | | | | | | This patch (as1263) fixes a mixup that occurred when conflicting patches for the sierra driver were merged incorrectly. The former sierra_shutdown routine should have been become sierra_release, not sierra_disconnect.

| | | | | | | | | | | | | | | | This patch (as1254) splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown.

* sierra: driver interface blacklistingElina Pasheva2009-06-111-3/+48
| | | | | | | | | | | | | | | | | | | | | | Interface blacklisting is necessary for non-serial interfaces that are handled by a different driver. The interface blacklisting is implemented in sierra driver per device. Each device in need of a blacklist has a static information array kept in the driver. This array contains the interface numbers that are blacklisted. The pointer for each blacklist array and the length of that blacklist are 'bundled' in data structure sierra_iface_info. A pointer to this information is set in id_table when the device is added to the id_table. The following is summary of changes we have made to sierra.c driver in this patch dealing with interface blacklisting support: - Added data structure sierra_iface_info and function is_blacklisted() to support blacklisting - Modified sierra_probe() to handle blacklisted interfaces accordingly - Improved comments in id_table - Added new device in id_table with blacklist interface support Signed-off-by: Elina Pasheva <epasheva@sierrawireless.com> Signed-off-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

This will save memory especially in the case of using composite devices. - The code has been re-organized and functionality has been extracted from sierra_startup(), sierra_shutdown(), sierra_open(), sierra_close() and added in helper functions sierra_release_urb(), sierra_stop_rx_urbs(), sierra_submit_rx_urbs() and sierra_setup_urb() - Added function sierra_release_urb() to free an urb and its transfer buffer. - Removed unecessary include file reference and comment. - Added function sierra_stop_rx_urbs() that takes care of the release of receive and interrupt urbs. This function is to be called by sierra_close() whenever an interface is de-activated. - Added new function sierra_submit_rx_urbs() that handles the submission of receive urbs and interrupt urbs (if any) during the interface activation. This function is to be called by sierra_open(). Added a second parameter to pass the memory allocation (as suggested by Oliver Neukum) so that this function can be used in post_reset() and resume(). - Added new function sierra_setup_urb() that contains the functionality to allocate an urb, fill bulk urb using the supplied memory allocation flag and release urb upon error. Added parameter so that the caller pass the memory allocation flag for flexibility. - Moved sierra_close() before sierra_open() to resolve dependencies introduced by the code reorganization. - Modified sierra_close() to call sierra_stop_rx_urbs() and sierra_release_urb() functions added in previous patch. - Modified sierra_open() to call sierra_setup_urb() and sierra_submit_rx_urbs() functions; note urbs are allocated and submitted for each activated interface. - Modified sierra_startup() so that allocation of urbs happens whenever an interface is activated (urb allocation is moved to sierra_open()). - Modified sierra_shutdown() so that urbs are freed whenever an interface is de-activated (urb freeing moved to sierra_close() as shown in previous patch from the series) - Removed unecessary data structure from sierra_port_private_data - Suppress an entry in logs by not re-submitting an urb when usb_submit_urb() returns -EPERM, as this shows that usb_kill_urb() is running (as suggested by Oliver Neukum) Signed-off-by: Elina Pasheva <epasheva@sierrawireless.com> Signed-off-by: Alan Cox <alan.cox@linux.intel.com> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

By doing this, it prevents users of kernels that do not enable this option from enabling debugging in these drivers, unlike all other usb-serial drivers.

* USB Serial Sierra: TRU-Install feature updateKevin Lloyd2008-08-131-32/+3
| | | | | | | | | Moves responsbility of TRU-Install (i.e. ZeroCD) to the usb-storage driver. See patch 04/04 of this set. Signed-off-by: Kevin Lloyd <klloyd@sierrawireless.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB Serial Sierra: Dynamic interface detectionKevin Lloyd2008-08-131-31/+52
| | | | | | | | | | This patch changes the method by which the number of ports per interface is assigned so that it is more dynamic and calculated on the fly (as opposed to hard coding it). This will allow for faster and easier addition of products. Signed-off-by: Kevin Lloyd <klloyd@sierrawireless.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB Serial Sierra: clean-upKevin Lloyd2008-08-131-29/+27
| | | | | | | | | | | Very minor changes to clean up sierra code. Adds a prefix to debug messages so that Sierra messages are easily recognized. Removes extraneous code.

* usb_serial: API all changeAlan Cox2008-07-221-64/+29
| | | | | | | | | | | | | | | | | | | USB serial likes to use port->tty back pointers for the real work it does and to do so without any actual locking. Unfortunately when you consider hangup events, hangup/parallel reopen or even worse hangup followed by parallel close events the tty->port and port->tty pointers are not guaranteed to be the same as port->tty is the active tty while tty->port is the port the tty may or may not still be attached to. So rework the entire API to pass the tty struct. For console cases we need to pass both for now. This shows up multiple drivers that immediately crash with USB console some of which have been fixed in the process. Longer term we need a proper tty as console abstraction Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* usb serial: more fixes and groundwork for tty changesAlan Cox2008-04-241-0/+2
| | | | | | | | | | | | | - If a termios change fails due to lack of memory we should copy the old settings back over as the device has not changed - Note various locking problems - kl5kusb105 had various remaining tty flag handling problems - Make safe_serial use tty_insert_flip_string not open coded loops - set termios speed properly in usb_serial Signed-off-by: Alan Cox <alan@redhat.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

* USB: serial: remove unneeded number endpoints settingsGreg Kroah-Hartman2008-04-241-3/+0
| | | | | | | | | The usb-serial core no longer checks these fields so remove them from all of the individual drivers. They will be removed from the usb-serial core in a patch later in the series. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
