For historical reasons, they are handled as plain USB devices. The current code makes more and more reference to the HID subsystem like implementing its own HID report descriptor parser to handle new devices. From the user point of view, we can transparently switch from this state to a driver handled in the HID subsystem and clean up a lot of USB specific code in the wacom.ko driver. The other benefit once the USB dependecies have been removed is that we can use a tool like uhid to make regression tests and allow further cleanup or new implementations without risking breaking current behaviors. To match the current handling of devices in wacom_wac.c, we rely on the hid_type set by usbhid. usbhid sets the hid_type to HID_TYPE_USBMOUSE when it sees a USB boot mouse protocol declared and HID_TYPE_USBNONE when the device is plain HID. There is thus a one to one matching between the list of supported devices before and after the switch from USB to HID.

We used some broken correlation between @report_done and @running so far. Replace it by a much more obvious use. We now wake up the report-cb if either @report_done or @running is set. wake_up() and wait_event() serve as implicit barriers (as they always do) so no need to use smp_rmb/wmb directly. Note that @report_done is never reset by anyone but the report-cb, thus it cannot flip twice while we wait for it. And whenever we set @running, we afterwards synchronously remove the HID device. Therefore, we wait for all report-cbs to finish before we return. This way, @running can never flip to true while we wait for it.

It was never clear what kind of HW request it should trigger. Benjamin fixed that with the core HID cleanup, though we never really adjusted uhid. Unfortunately, our old UHID_FEATURE command was modelled around the broken hid_get_raw_report(). We converted it silently to the new GET_REPORT and nothing broke. Make this explicit by renaming UHID_FEATURE to UHID_GET_REPORT and UHID_FEATURE_ANSWER to UHID_GET_REPORT_REPLY. Note that this is 100% ABI compatible to UHID_FEATURE. This is just a rename. But we have to keep the old definitions around to not break API. >From now on, UHID_GET_REPORT must trigger a GET_REPORT request on the user-space hardware layer. All the ambiguity due to the weird "feature" name should be gone now.

Note that SET_REPORT is synchronous, just like GET_REPORT, even though it does not provide any data back besides an error code. If a transport layer does SET_REPORT asynchronously, they can just ACK it immediately by writing an uhid_set_report_reply to uhid. This patch re-uses the synchronous uhid-report infrastructure to query user-space. Note that this means you cannot run SET_REPORT and GET_REPORT in parallel. However, that has always been a restriction of HID and due to its blocking nature, this is just fine. Maybe some future transport layer supports parallel requests (very unlikely), however, until then lets not over-complicate things and avoid request-lookup-tables.

The first flags we introduce describe whether a given report-type uses numbered reports. This is useful for transport layers that force report-numbers and therefore might have to prefix kernel-provided HID-messages with the report-number. Currently, only HoG needs this and the spec only talks about "global report numbers". That is, it's a global boolean not a per-type boolean. However, given the quirks we already have in kernel-space, a per-type value seems much more appropriate.

Currently, after a Clear-Halt on the interrupt-IN endpoint, the driver immediately restarts the interrupt URB, even if the Clear-Halt failed. This doesn't work out well when the reason for the failure was that the device was disconnected (when a low- or full-speed device is connected through a hub to an EHCI controller, transfer errors caused by disconnection are reported as stalls by the hub). Instead now the driver will attempt a reset after a failed Clear-Halt. The way resets are carried out is also changed. Now the driver will call usb_queue_reset_device() instead of calling usb_reset_device() directly. This avoids a deadlock that would arise when a device is unplugged: The hid_reset() routine runs as a workqueue item, a reset attempt after the device has been unplugged will fail, failure will cause usbhid to be unbound, and the disconnect routine will try to do cancel_work_sync(). The usb_queue_reset_device() implementation is carefully written to handle scenarios like this one properly.

There is no way for the user space to know which one is which besides parsing the name. We can force the PID to be set to the actual hardware. This way, the input device will have the correct PID which can be match in libwacom. With only this trick, the pad input does not inherit the ID_INPUT_TABLET udev property from its parent. We can force udev to accept it by declaring a BTN_STYLUS which is never used. This way, tablets connected through WL can be used from the user point of view in the same way they are used while connected through wire.

We can directly implement a generic HID parsing/handling and remove the need to manually add those PID in the list of supported devices. This patch implements the pen support only. The finger part will come in a later patch. To be properly notified of an .event() and a .report(), we need to force hid-core to go through the HID parsing. By default, wacom.ko binds only hidraw, so the hid parsing is not done by hid-core. When a true HID device is there, we add the flag HID_CLAIMED_DRIVER to hid->claimed which will force hid-core to parse the incoming reports. (Note that this can be easily backported by directly setting the .claimed flag to HID_CLAIMED_DRIVER even if hid-core does not support HID_CONNECT_DRIVER) Signed-off-by: Benjamin Tissoires Acked-by: Jason Gerecke Signed-off-by: Jiri Kosina --- drivers/hid/hid-core.c | 3 + drivers/hid/wacom.h | 6 ++ drivers/hid/wacom_sys.c | 12 +++- drivers/hid/wacom_wac.c | 179 ++++++++++++++++++++++++++++++++++++++++++++++++ drivers/hid/wacom_wac.h | 8 +++ include/linux/hid.h | 2 + 6 files changed, 208 insertions(+), 2 deletions(-) (limited to 'drivers/hid') diff --git a/drivers/hid/hid-core.c b/drivers/hid/hid-core.c index 12b6e67d9de0..583344dba3c6 100644 --- a/drivers/hid/hid-core.c +++ b/drivers/hid/hid-core.c @@ -1591,6 +1591,9 @@ int hid_connect(struct hid_device *hdev, unsigned int connect_mask) if ((connect_mask & HID_CONNECT_HIDRAW) && !hidraw_connect(hdev)) hdev->claimed |= HID_CLAIMED_HIDRAW;

Then, the protocol says that the user space asnwers with UHID_GET_REPORT_REPLY or UHID_SET_REPORT_REPLY. Unfortunatelly, the current code waits for an event of type UHID_GET_REPORT or UHID_SET_REPORT instead of the reply one. Add 1 to UHID_GET_REPORT or UHID_SET_REPORT to actually wait for the reply, and validate the reply.
