2008-04-24USB: usbatm: convert heavy init dances to kthread APIPavel Emelyanov
This is an attempt to kill two birds with one stone. First, we kill one more user of kernel_thread, which is scheduled for removal. Second - we kill one of the last users of kill_proc - the function which is also to be removed, because it uses a pid_t which is not safe now.

2007-10-12USB: cxacru: Use appropriate logging for errorsSimon Arlott
When an error occurs, existing logging uses dbg() so the cause of a problem is hard to determine. Error conditions shouldn't only be properly reported with debugging enabled. A side effect of this change is that when an uninitialised device is started, a log message similar to the following is sent: cxacru 5-2:1.0: receive of cm 0x90 failed (-104) This is normal - the device did not respond so firmware will be loaded.

2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

2007-07-12USB: cxacru: Cleanup sysfs attribute codeSimon Arlott
This changes the format of unknown status values to be less verbose and uses an array instead of several different snprintf calls. Since only enum values are assigned to it, poll_state is changed from int to enum. Use abs() for dB values instead of two almost identical return lines.

2007-06-08USB: cxacru: ignore error trying to start ADSL in atm_startSimon Arlott
The sysfs adsl_status attribute ignores (aside from returning -EIO to the user) any error sending a START/STOP command to the device and there is at least one firmware which never sends a response but appears to work regardless. Therefore atm_start should also continue if an error is received so that such firmware is usable. The official Conexant driver doesn't expect a reply either but this is for another device (E2 router) and a commonly used firmware does respond. Also, there is no point in changing -ECONNRESET to -ETIMEDOUT since nothing ever checks for either of these values.

2007-06-08USB: cxacru: create sysfs attributes in atm_start instead of bindSimon Arlott
Since usbatm doesn't set the usb_interface driver data until after calling bind and heavy_init, it would be NULL when the sysfs attributes are read. Reading the MAC address from atm_dev before atm_dev exists would have been be possible too. Calling create_device_file in atm_start will avoid this problem, and the data is useless until the first status poll runs. However, it must be ready before a status poll does a printk on line status change otherwise userspace could react before the files exist. For completeness I've moved remove_device_file to atm_stop so it's not called in unbind when it's not needed. There's no point starting ADSL if atm_start could still fail either.

2007-04-27USB: cxacru: ADSL state managementSimon Arlott
The device has commands to start/stop the ADSL function, so this adds a sysfs attribute to allow it to be started/stopped/restarted. It also stops polling the device for status when the ADSL function is disabled. There are no problems with sending multiple start or stop commands, even with a fast loop of them the device still works. There is no need to protect the restart process from further user actions while it's waiting for 1.5s.

2007-04-27USB: cxacru: export detailed device info through sysfsSimon Arlott
When the device is polled for status there is a lot of useful status information available that is ignored. This patch stores the device info array when the status is polled and adds sysfs files to the usb device to allow userspace to query it. Since the device updates its status internally once a second the poll time is changed to this, and round_jiffies_relative is used to avoid waking the cpu unnecessarily.

2007-04-27usbatm: create sysfs link "device" from atm class device to usb interfaceSimon Arlott
There is currently no path from the ATM device in /sys to the USB device's interface that the driver is using; this patch creates a "device" symlink. It is then possible to get to the cxacru ADSL statistics (http://lkml.org/lkml/2007/2/23/328): /sys/class/atm/cxacru0/device $ ls *_rate *_margin *_attenuation downstream_attenuation downstream_snr_margin upstream_rate downstream_rate upstream_attenuation upstream_snr_margin If this link is not appropriate I'd have to create device files in /sys/class/atm/cxacru0 instead - which seems less appropriate since the ADSL statistics are for the USB device not ATM (which is running over the ADSL).

2006-10-17speedtch: "extended reach"Duncan Sands
The speedtouch modem setup code was reverse engineered many years ago from a prehistoric windows driver. Less ancient windows drivers, even those from a few years ago, perform extra initialization steps which this patch adds to the linux driver. David Woodhouse observed that this initialization along with the firmware bin/sachu3/zzzlp2.eni from the driver at http://www.speedtouch.co.uk/downloads/330/301/UK3012%20Extended.zip improves line sync speeds by about 20%. He provided the original patch, which I've modified to use symbolic names (BMaxDSL, ModemMode, ModemOption) rather than magic numbers. These names may not seem like much of an improvement (after all, what is "ModemOption" exactly?), but they do have one big advantage: they are the names used in the windows registry. I've made them available as module parameters. Thanks are due to Aurelio Arroyo, who noticed the relationship between these magic numbers and the entries in Phonebook.ini.
