Make the appending of the HID++ descriptors in logi_dj_ll_parse conditional. This is a preparation patch for adding support for the Logitech mini Bluetooth receiver in HID proxy mode (its default mode), where some of the paired devices may not be Logitech devices and thus may not be HID++ capable. This uses a fake bit 63 in reports_supported, which is changed from an u32 to an u64 for this. Bits <= 31 are not usable for this because that would cause a behavioral change in logi_dj_recv_forward_null_report. Signed-off-by:

The various functions queueing work-items do not check there already is a work-item queued before calling schedule_work(), as such they may race with each-other and with the re-queuing done by the delayedwork_callback itself. This is fine as the delayedwork_callback simply is a nop if scheduled once too much. I've actually seen the false-positive hid_err for this trigger in practice, so lets remove it. While at it also remove the somewhat overzealous debugging around the schedule_work() calls. Signed-off-by:

hidpp_unifying_get_name() does not work for devices attached to non-unifying receivers. Since we do get a device-type in the device- connection report, we can pick a better name for these devices in hid-logitech-dj.c . Signed-off-by:

My Aten cs1764a KVM adds an extra interface to the receiver through which it forwards mouse events, if a separate mouse is plugged in next to the receiver dongle. This interface is present even if no extra mouse is plugged in. logitech-dj trying to handle this extra interface causes mouse events send through the extra interface to not be properly handled. This commit fixes this by treating any extra interfaces as hid-generic interfaces. Signed-off-by:

27 MHz mouse-only receivers send an unnumbered input report with the mouse data, add special handling for this and add the c51b product-id to the logi_dj_receivers table. Signed-off-by:
-
Hans de Goede authored
Most Logitech wireless keyboard and mice using the 27 MHz are hidpp10 devices, add support to logitech-dj for their receivers. Doing so leads to 2 improvements: 1) All these devices share the same USB product-id for their receiver, making it impossible to properly map some special keys / buttons which differ from device to device. Adding support to logitech-dj to see these as hidpp10 devices allows us to get the actual device-id from the keyboard / mouse. 2) It enables battery-monitoring of these devices This patch uses a new HID group for 27Mhz devices, since the logitech-hidpp code needs to be able to differentiate them from other devices instantiated by the logitech-dj code.

This receiver is almost identical to the normal unifying ones except: - it is supposed to be paired to only one device (for performance reasons) - the mice reports have a greater ranges in their values, so they are using a different report ID. Tested on a G403 and a G900. Co-authored-by:

We emulate the DJ functionality through the driver. The receiver supports "fake device arrival" which behaves like the probing of DJ devices. A non-unifying receiver has 2 USB interfaces, the first one generates standard keypresses and is compatible with the USB Keyboard Boot Subclass. The second interface sends events for the mouse and special keys such as the consumer-page keys. Events are split this way for BIOS / Windows / generic-hid driver compatibility. This split does not actually match with which device the event originate from, e.g. the consumer-page key events originate from the keyboard but are delivered on the mouse interface. To make sure the events are actually delivered to the dj_device representing the originating device, we pick which dj_dev to forward a "regular" input-report to based on the report-number, rather then based on the originating interface.

Add a logi_dj_recv_queue_unknown_work helper and implement query rate-limiting inside this helper. The motivations behind this are: 1) We need to queue workitems for reports with no place to forward them from more places with the upcoming non-unifying receiver support, hence the addition of the helper function. 2) When we've missed a pairing info report (or there is a race between the report and input-events) and the input report is e.g. from a mouse being moved, we will get a lot of these before we've finished (re-) querying and enumerating the devices, hence the rate-limiting. Note this also removes the: if (!djrcv_dev->paired_dj_devices[hidpp_report->device_index]) check previously guarding the sending of an unknown workitem, the caller of logi_dj_recv_queue_notification already does this check before calling logi_dj_recv_queue_notification.

dj/HID++ receivers are really a single logical entity, but for BIOS/Windows compatibility they have multiple USB interfaces. For the upcoming non-unifying receiver support, we need to listen for events from / bind to all USB-interfaces of the receiver. This commit add support to the logitech-dj code for creating a single dj_receiver_dev struct for all interfaces belonging to a single USB-device / receiver, in preparation for adding non-unifying receiver support. Signed-off-by:

Hans de Goede authored
For the upcoming non-unifying receiver support, we are going to bind to all USB-interfaces of a receiver, sharing a single struct dj_receiver_dev between the interfaces. This means that dj_receiver_dev will contain multiple pointers to a struct hid_device. Rename the current hdev member to hidpp to prepare for this. While at it switch dev_err calls which we are touching anyways from dev_err to hid_err. Signed-off-by:

This protects against logi_dj_recv_add_djhid_device, adding a device to paired_dj_devices from the delayedwork callback, racing versus logi_dj_raw_event trying to access that device. Signed-off-by:

This is a preparatory patch for handling non DJ (HID++ only) receivers, through this module. We can not use the dj_report in the delayed work callback as the HID++ notifications are different both in size and meaning. There should be no functional change. Signed-off-by:

It is better to rely on the actual content of the report descriptors to enable or not a HID interface. While at it, remove the other USB dependency to have a fully USB agnostic driver. Signed-off-by:

logi_dj_recv_forward_report() was only intended for DJ reports. logi_dj_recv_forward_hidpp() is more generic at forwarding random HID reports. So rename logi_dj_recv_forward_report() into logi_dj_recv_forward_dj() and logi_dj_recv_forward_hidpp() into logi_dj_recv_forward_report(). Signed-off-by:

I am actually suggesting people to not populate this list, and I should probably start to apply my advices to myself. The end result means that if your initrd is lacking hid-logitech-dj or hid-logitech-hidpp, but still contains hid-generic, then your keyboard will work during pre-init. Signed-off-by:

We have a new Dell laptop which has the synaptics I2C touchpad (06cb:7e7e) on it. After booting up the Linux, the touchpad doesn't work, there is no interrupt when touching the touchpad, after disable the runtime PM, everything works well. I also tried the quirk of I2C_HID_QUIRK_DELAY_AFTER_SLEEP, it is better after applied this quirk, there are interrupts but data it reports is invalid. Signed-off-by:

According to hidpp20_batterylevel_get_battery_info my Logitech K270 keyboard reports only 2 battery levels. This matches with what I've seen after testing with batteries at varying level of fullness, it always reports either 5% or 30%. Windows reports "battery good" for the 30% level. I've captured an USB trace of Windows reading the battery and it is getting the same info as the Linux hidpp code gets. Now that Linux handles these devices as hidpp devices, it reports the battery as being low as it treats anything under 31% as low, this leads to the user constantly getting a "Keyboard battery is low" warning from GNOME3, which is very annoying. This commit fixes this by changing the low threshold to anything under 30%, which I assume is what Windows does. Signed-off-by:

Similar to commit edfc3722 ("HID: quirks: Fix keyboard + touchpad on Toshiba Click Mini not working"), the Lenovo Miix 630 has a combo keyboard/touchpad device with vid:pid of 04F3:0400, which is shared with Elan touchpads. The combo on the Miix 630 has an ACPI id of QTEC0001, which is not claimed by the elan_i2c driver, so key on that similar to what was done for the Toshiba Click Mini. Signed-off-by:

When using this driver with the wireless dongle and some usermode program that monitors every input device (acpid, for example), while another usermode client opens and closes the low-level device repeadedly, the system eventually deadlocks. The reason is that steam_input_register_device() must not be called with the mutex held, because the input subsystem has its own synchronization that clashes with this one: it is possible that steam_input_open() is called before input_register_device() returns, and since steam_input_open() needs to lock the mutex, it deadlocks. However we must hold the mutex when calling any function that sends commands to the controller. If not, random commands end up falling fail. Reported-by:
