2007-04-28[PATCH] Update my email address from jkmaline@cc.hut.fi to j@w1.fiJouni Malinen
After 13 years of use, it looks like my email address is finally going to disappear. While this is likely to drop the amount of incoming spam greatly ;-), it may also affect more appropriate messages, so let's update my email address in various places. In addition, Host AP mailing list is subscribers-only and linux-wireless can also be used for discussing issues related to this driver which is now shown in MAINTAINERS.

2007-04-28tc35815 driver update (take 2)Atsushi Nemoto
Current tc35815 driver is very obsolete and less maintained for a long time. Replace it with a new driver based on one from CELF patch archive. Major advantages of CELF version (version 1.23, for kernel 2.6.10) are: * Independent of JMR3927. (Actually independent of MIPS, but AFAIK the chip is used only on MIPS platforms) * TX4938 support. * 64-bit proof. * Asynchronous and on-demand auto negotiation. * High performance on non-coherent architecture. * ethtool support. * Many bugfixes and cleanups. And improvoments since version 1.23 are: * TX4939 support. * NETPOLL support. * NAPI support. (disabled by default) * Reduce memcpy on receiving. * PM support. * Many cleanups and bugfixes.

2007-04-27USB: add "last_busy" field for use in autosuspendAlan Stern
This patch (as877) adds a "last_busy" field to struct usb_device, for use by the autosuspend framework. Now if an autosuspend call comes at a time when the device isn't busy but hasn't yet been idle for long enough, the timer can be set to exactly the desired value. And we will be ready to handle things like HID drivers, which can't maintain a useful usage count and must rely on the time-of-last-use to decide when to autosuspend. The patch also makes some related minor improvements: Move the calls to the autosuspend condition-checking routine into usb_suspend_both(), which is the only place where it really matters. If the autosuspend timer is already running, don't stop and restart it. Replace immediate returns with gotos so that the optional debugging ouput won't be bypassed. If autoresume is disabled but the device is already awake, don't return an error for an autoresume call. Don't try to autoresume a device if it isn't suspended. (Yes, this undercuts the previous change -- so sue me.) Don't duplicate existing code in the autosuspend work routine. Fix the kerneldoc in usb_autopm_put_interface(): If an autoresume call fails, the usage counter is left unchanged.

2007-04-27USB: make usbdevices export their device nodes instead of using a separate classKay Sievers
o The "real" usb-devices export now a device node which can populate /dev/bus/usb. o The usb_device class is optional now and can be disabled in the kernel config. Major/minor of the "real" devices and class devices are the same. o The environment of the usb-device event contains DEVNUM and BUSNUM to help udev and get rid of the ugly udev rule we need for the class devices. o The usb-devices and usb-interfaces share the same bus, so I used the new "struct device_type" to let these devices identify themselves. This also removes the current logic of using a magic platform-pointer. The name of the device_type is also added to the environment which makes it easier to distinguish the different kinds of devices on the same subsystem. It looks like this: add@/devices/pci0000:00/0000:00:1d.1/usb2/2-1 ACTION=add DEVPATH=/devices/pci0000:00/0000:00:1d.1/usb2/2-1 SUBSYSTEM=usb SEQNUM=1533 MAJOR=189 MINOR=131 DEVTYPE=usb_device PRODUCT=46d/c03e/2000 TYPE=0/0/0 BUSNUM=002 DEVNUM=004 This udev rule works as a replacement for usb_device class devices: SUBSYSTEM=="usb", ACTION=="add", ENV{DEVTYPE}=="usb_device", \ NAME="bus/usb/$env{BUSNUM}/$env{DEVNUM}", MODE="0644" Updated patch, which needs the device_type patches in Greg's tree.

2007-04-27USB: add power/level sysfs attributeAlan Stern
This patch (as874) adds another piece to the user-visible part of the USB autosuspend interface.

Now a delay of 0 means to autosuspend as soon as possible, and negative values will prevent autosuspend.

The values can be set throgh the attach inform or through the extended TUNER_SET_TYPE_ADDR client call. The function pointer will only be updated if the parameter is not NULL.

2007-04-27define platform wakeup hook, use in pci_enable_wake()David Brownell
This defines a platform hook to enable/disable a device as a wakeup event source. It's initially for use with ACPI, but more generally it could be used whenever enable_irq_wake()/disable_irq_wake() don't suffice. The hook is called -- if available -- inside pci_enable_wake(); and the semantics of that call are enhanced so that support for PCI PME# is no longer needed. It can now work for devices with "legacy PCI PM", when platform support allows it. (That support would use some board-specific signal for for the same purpose as PME#.)

2007-04-27Driver core: remove unneeded completion from driver release pathGreg Kroah-Hartman
The completion in the driver release path is due to ancient history in the _very_ early 2.5 days when we were not tracking the module reference count of attributes. It is not needed at all and can be removed. Note, we now have an empty release function for the driver structure. This is due to the fact that drivers are statically allocated in the system at this point in time, something which I want to change in the future. But remember, drivers are really code, which is reference counted by the module, unlike devices, which are data and _must_ be reference counted properly in order to work correctly.

2007-04-27Driver core: add name to device_typeKay Sievers
If "name" of a device_type is specified, the uevent will contain the device_type name in the DEVTYPE variable. This helps userspace to distingiush between different types of devices, belonging to the same subsystem.

2007-04-27driver core: Use attribute groups in struct device_typeDmitry Torokhov
Driver core: use attribute groups in struct device_type Attribute groups are more flexible than attribute lists (an attribute list can be represented by anonymous group) so switch struct device_type to use them. Also rework attribute creation for devices so that they all cleaned up properly in case of errors.

2007-04-27Driver core: udev triggered device-<>driver bindingKay Sievers
We get two per-bus sysfs files: ls-l /sys/subsystem/usb drwxr-xr-x 2 root root 0 2007-02-16 16:42 devices drwxr-xr-x 7 root root 0 2007-02-16 14:55 drivers -rw-r--r-- 1 root root 4096 2007-02-16 16:42 drivers_autoprobe --w------- 1 root root 4096 2007-02-16 16:42 drivers_probe The flag "drivers_autoprobe" controls the behavior of the bus to bind devices by default, or just initialize the device and leave it alone. The command "drivers_probe" accepts a bus_id and the bus tries to bind a driver to this device. Systems who want to control the driver binding with udev, switch off the bus initiated probing: echo 0 > /sys/subsystem/usb/drivers_autoprobe echo 0 > /sys/subsystem/pcmcia/drivers_autoprobe ... and initiate the probing with udev rules like: ACTION=="add", SUBSYSTEM=="usb", ATTR{subsystem/drivers_probe}="$kernel" ACTION=="add", SUBSYSTEM=="pcmcia", ATTR{subsystem/drivers_probe}="$kernel" ... Custom driver binding can happen in earlier rules by something like: ACTION=="add", SUBSYSTEM=="usb", \ ATTRS{idVendor}=="1234", ATTRS{idProduct}=="5678" \ ATTR{subsystem/drivers/<custom-driver>/bind}="$kernel" This is intended to solve the modprobe.conf mess with "install-rules", custom bind/unbind-scripts and all the weird things people invented over the years. It should also provide the functionality "libusual" was supposed to do. With udev, one can just write a udev rule to drive all USB-disks at the third port of USB-hub by the "ub" driver, and everything else by usb-storage. One can also instruct udev to bind different wireless drivers to identical cards - just selected by the pcmcia slot-number, and whatever ... To use the mentioned rules, it needs udev version 106, to be able to write ATTR{}="$kernel" to sysfs files. Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-04-27driver core: fix namespace issue with devices assigned to classesKay Sievers
- uses a kset in "struct class" to keep track of all directories belonging to this class - merges with the /sys/devices/virtual logic. - removes the namespace-dir if the last member of that class leaves the directory. There may be locking or refcounting fixes left, I stopped when it seemed to work with network and sound modules. :) From: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2007-04-27make SysRq-T show all tasks againIngo Molnar
show_state() (SysRq-T) developed the buggy habbit of not showing TASK_RUNNING tasks. This was due to the mistaken belief that state_filter == -1 would be a pass-through filter - while in reality it did not let TASK_RUNNING == 0 p->state values through. Fix this by restoring the original '!state_filter means all tasks' special-case i had in the original version. Test-built and test-booted on i686, SysRq-T now works as intended.
