2007-10-19Use helpers to obtain task pid in printksPavel Emelyanov
The task_struct->pid member is going to be deprecated, so start using the helpers (task_pid_nr/task_pid_vnr/task_pid_nr_ns) in the kernel. The first thing to start with is the pid, printed to dmesg - in this case we may safely use task_pid_nr(). Besides, printks produce more (much more) than a half of all the explicit pid usage.

2007-10-14HID: add hidraw interfaceJiri Kosina
hidraw is an interface that is going to obsolete hiddev one day. Many userland applications are using libusb instead of using kernel-provided hiddev interface. This is caused by various reasons - the HID parser in kernel doesn't handle all the HID hardware on the planet properly, some devices might require its own specific quirks/drivers, etc. hiddev interface tries to do its best to parse all the received reports properly, and presents only parsed usages into userspace. This is however often not enough, and that's the reason why many userland applications just don't use hiddev at all, and rather use libusb to read raw USB events and process them on their own. Another drawback of hiddev is that it is USB-specific. hidraw interface provides userspace readers with really raw HID reports, no matter what the low-level transport layer is (USB/BT), and gives the userland applications all the freedom to process the HID reports in a way they wish to.

2007-10-14HID: hiddev: Add 32bit ioctl compatibiltyPhilip Langdale
The hiddev driver currently lacks 32bit ioctl compatibility, so if you're running with a 64bit kernel and 32bit userspace, it won't work. I'm pretty sure that the only thing missing is a compat_ioctl implementation as all structs have fixed size fields. With this change I can use revoco to configure my MX Revolution mouse.

2007-10-14HID: enable hiddev for the SantaRosa MacBookPro IR receiverStelian Pop
The infrared remote receiver found in the SantaRosa MacBookPro laptops (MacBookPro3,1) need to be forced to expose a HIDDEV interface (instead of HIDINPUT) so that lirc can access it using the 'macmini' driver. The patch below adds the required quirk for forcing the HIDDEV interface to be activated (HID_QUIRK_HIDDEV) and introduces a new quirk which forces the HIDINPUT interface to be ignored (HID_QUIRK_IGNORE_HIDINPUT). Note that Apple calls this receiver 'IRController4' (info taken from Apple's driver Info.plist). Older Mac{Book,Mini,Pro}s seem to all use the 'IRController1' device (USB id 05ac:8240) which doesn't need those quirks.

2007-10-14HID: Report usage codes of keys as EV_MSC scancode eventsJiri Kosina
Current HID layer does not report usage codes to the input layer. This feature was previously removed, because it caused unnecessary storm of events in cases of positioning devices, etc. This patch adds reporting of usage codes as EV_MSC events only for key events. We issue the EV_MSC event only if the state of the key corresponding to the given code has changed, so that we don't report usages that are sent in every report even if the state hasn't changed (for example Shift/Caps Lock/... states as sent by various keyboards). This functionality is required at least by KeyTouch in order to provide convenient means for remapping the usage codes.

2007-07-12USB: add reset_resume methodAlan Stern
This patch (as918) introduces a new USB driver method: reset_resume. It is called when a device needs to be reset as part of a resume procedure (whether because of a device quirk or because of the USB-Persist facility), thereby taking over a role formerly assigned to the post_reset method. As a consequence, post_reset no longer needs an argument indicating whether it is being called as part of a reset-resume. This separation of functions makes the code clearer. In addition, the pre_reset and post_reset method return types are changed; they now must return an error code. The return value is unused at present, but at some later time we may unbind drivers and re-probe if they encounter an error during reset handling. The existing pre_reset and post_reset methods in the usbhid, usb-storage, and hub drivers are updated to match the new requirements. For usbhid the post_reset routine is also used for reset_resume (duplicate method pointers); for the other drivers a new reset_resume routine is added. The change to hub.c looks bigger than it really is, because mark_children_for_reset_resume() gets moved down next to the new hub_reset_resume() routine. A minor change to usb-storage makes the usb_stor_report_bus_reset() routine acquire the host lock instead of requiring the caller to hold it already.

2007-07-12USB: add USB-Persist facilityAlan Stern
This patch (as886) adds the controversial USB-persist facility, allowing USB devices to persist across a power loss during system suspend. The facility is controlled by a new Kconfig option (with appropriate warnings about the potential dangers); when the option is off the behavior will remain the same as it is now. But when the option is on, people will be able to use suspend-to-disk and keep their USB filesystems intact -- something particularly valuable for small machines where the root filesystem is on a USB device!

There are some devices (for example Dell Multimedia Keyboard SK-8135) that have a volume control knob which generates relative events instead of absolute. hid-input maps them to ABS_VOLUME. HUT pages don't restrict volume to absolute values. Adding REL_VOLUME doesn't seem feasible, nothing knows how to handle it.

2007-07-09HID: separate quirks for report descriptor fixupJiri Kosina
Lately there have been quite a lot of bug reports against broken devices which require us to fix their report descriptor in the runtime, before it is passed to the HID parser. Those devices have eaten quite an amount of our quirks space, which isn't particularly necessary - the quirks are not needed after the report descriptor is parsed, and they just consume bits. Therefore this patch separates the quirks for report descriptor fixup, and moves their handling into separate code. The quirks are then forgotten as soon as the report descriptor has been parsed. Module parameter 'rdesc_quirks' is introduced to be able to modify these quirks in runtime in a similar way to 'quirks' parameter for ordinary HID quirks. Signed-off-by: Jiri Kosina <jkosina@suse.cz>

It also emits a few usages from LOGIVENDOR page, which need adding. Also, this device has broken report descriptor - the reported maximum is too low - it doesn't contain the range for 'back' and 'more' keys, so we need to bump it up before the report descriptor is being parsed. Besides all this, it also requires NOGET quirk. This patch does so.
