Nothing special to take care of. We report this to user-space as "Nintendo Wii Remote Drums". There are other drums (like "RockBand" drums) which we currently do not support and maybe will at some point. However, it is quite likely that we can report these via the same interface.

2013-08-27HID: do not init input reports for Win 8 multitouch devicesBenjamin Tissoires
Some multitouch screens do not like to be polled for input reports. However, the Win8 spec says that all touches should be sent during each report, making the initialization of reports unnecessary. The Win7 spec is less precise, so do not use this for those devices. Add the quirk HID_QUIRK_NO_INIT_INPUT_REPORTS so that we do not have to introduce a quirk for each problematic device. This quirk makes the driver behave the same way the Win 8 does. It actually retrieves the features, but not the inputs.

2013-08-27HID: detect Win 8 multitouch devices in coreBenjamin Tissoires
Detecting Win 8 multitouch devices in core allows us to set quirks before the device is parsed through hid_hw_start(). It also simplifies the detection of those devices in hid-multitouch and makes the handling of those devices cleaner. As Win 8 multitouch panels are in the group multitouch and rely on a special feature to be detected, this patch adds a bitfield in the parser.

2013-08-27HID: Use hid_parser for pre-scanning the report descriptorsBenjamin Tissoires
The Win 8 detection is sufficiently complex to warrant use of the full parser code, in spite of the inferred memory usage. Therefore, we can use the existing HID parser in hid-core for hid_scan_report() by re-using the code from hid_open_report(). hid_parser_global, hid_parser_local and hid_parser_reserved does not have any side effects. We just need to reimplement the MAIN_ITEM callback to have a proper parsing without side effects.

2013-08-09Revert "HID: hid-logitech-dj: querying_devices was never set"Jiri Kosina
This reverts commit 407a2c2a4d85100c8c67953e4bac2f4a6c942335. Explanation provided by Benjamin Tissoires: Commit "HID: hid-logitech-dj, querying_devices was never set" activate a flag which guarantees that we do not ask the receiver for too many enumeration. When the flag is set, each following enumeration call is discarded (the usb request is not forwarded to the receiver). The flag is then released when the driver receive a pairing information event, which normally follows the enumeration request. However, the USB3 bug makes the driver think the enumeration request has been forwarded to the receiver. However, it is actually not the case because the USB stack returns -EPIPE. So, when a new unknown device appears, the workaround consisting in asking for a new enumeration is not working anymore: this new enumeration is discarded because of the flag, which is never reset. A solution could be to trigger a timeout before releasing it, but for now, let's just revert the patch.

This changes puts the commit 4fe9f8e203f back in place with the fixes for slab corruption because of the commit. When a device is unplugged, wait for all processes that have opened the device to close before deallocating the device. This commit was solving kernel crash because of the corruption in rb tree of vmalloc. The rootcause was the device data pointer was geting excessed after the memory associated with hidraw was freed. The commit 4fe9f8e203f was buggy as it was also freeing the hidraw first and then calling delete operation on the list associated with that hidraw leading to slab corruption.

2013-08-05HID: wiimote: work around broken DRM_KAI on GEN10David Herrmann
GEN10 and earlier devices seem to not support DRM_KAI if we run in basic IR mode. Use DRM_KAIE instead. This might increases overhead slightly as the extension port is read and streamed but we stream accelerometer data constantly, too, so this is negligible. Note that our parsers are hardcoded on IR-formats, so we cannot actually use 96-bit IR DRMs for basic IR data. We would have to adjust the parsers. But as only GEN20 and newer support this, we simply avoid mixed DRMs. This fixes a bug where GEN10 devices didn't provide IR data if accelerometer and IR are enabled simultaneously. As a workaround, you can enable DRM_KAIE without this patch via (disables device power-management): echo "37" >/sys/kernel/debug/hid/<dev>/drm Cc: stable@vger.kernel.org Signed-off-by: David Herrmann <dh.herrmann@gmail.com> Reported-by: Nicolas Adenis-Lamarre <nicolas.adenis.lamarre@gmail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>
