From d8aaccda7144df1c3d35251313197aed4cbea7bc Mon Sep 17 00:00:00 2001 From: Frank Praznik Date: Wed, 11 Nov 2015 09:49:37 -0500 Subject: HID: sony: Refactor the output report sending functions Refactor the output report sending functions to allow for the sending of output reports without enqueuing a work item. Output reports for any device can now be sent via the send_output_report function pointer in the sony_sc struct which points to the appropriate output function. The individual state worker functions have been replaced with a universal sony_state_worker function which uses this function pointer.

Additionally, the state of the controllers on resume may be different from the state they were in at the time when they were suspended (ie. LEDs are cleared on resume). This implements the suspend and resume callbacks which saves and clears the state of the LEDs on suspend and restores them on resume. Force-feedback is stopped on suspend but not automatically restored on resume until a new event is received to avoid potentially damaging hardware. USB Sixaxis and navigation controllers must be reinitialized when the hardware is reset on resume or they won't send any input reports.

This wheel 'speaks' the HID++ protocol, and therefor is driven with hid-logitech-hidpp. At this stage the driver only shows that it can communicate with the wheel by outputting the name discovered over HID++. The normal HID functions work to give input functionality using joystick/event interface. Note: in 'hidpp_probe()' we have to start the hardware to get packets flowing, the same might apply in future for other devices which don't use the unifying protocol.

First, we do a strlen() call for every byte we copy (we're doing a store to global memory, so gcc has no way of proving that strlen(buf) doesn't change). Second, since both i, list->tail and HID_DEBUG_BUFSIZE have signed type, the modulo computation has to take into account the possibility that list->tail+i is negative, so it's not just a simple and. Fix the former by simply not doing strlen() at all (we have to load buf[i] anyway, so testing it is almost free) and the latter by changing i to unsigned. This cuts 29% (69 bytes) of the size of the function.

"Too big" means the case statement and the call to hid_input_report() do not need to be protected by the spinlock (no URB operations are done inside them). The deadlock happens because in certain rare cases drivers try to grab the lock while handling the ctrl irq which grabs the lock before them as described above. For example newer wacom tablets like 056a:033c try to reschedule proximity reads from wacom_intuos_schedule_prox_event() calling hid_hw_request() -> usbhid_request() -> usbhid_submit_report() which tries to grab the usbhid lock already held by hid_ctrl(). There are two ways to get out of this deadlock: 1. Make the drivers work "around" the ctrl critical region, in the wacom case for ex. by delaying the scheduling of the proximity read request itself to a workqueue. 2. Shrink the critical region so the usbhid lock protects only the instructions which modify usbhid state, calling hid_input_report() with the spinlock unlocked, allowing the device driver to grab the lock first, finish and then grab the lock afterwards in hid_ctrl(). This patch implements the 2nd solution.

Given that we did not checked if one was previously assigned, we were dealing with the ignored featured and we should never have been able to switch this panel into the multitouch mode. However, the firmware presents an other bugs which allowed 6d4f5440 to counteract the faulty report descriptor. When we request the values of the feature 5, the firmware answers "03 03 00". The fields are correct but the report id is wrong. Before 6d4f5440, we retrieved all the features and injected them in the system. So when we called report 5, we injected in the system the report 3 with the values "03 00". Setting the second input mode to 03 in this report changed it to "03 03" and the touchpad switched to the mt mode. We could have set anything in the second field because the actual value (the first 03 in this report) was given by the query of report ID 5. To sum up: 2 bugs in the firmware were hiding that we were accessing the wrong feature.

I am reverting this one, while keeping the rest of the G920 support in, so that it immediately starts working once proper HID-mode switching is implemented. Quoting Dmitry Torokhov for rationale: == It is wrong. Aside form the fact that IMO xpad.c is the wrong place for this code to be in, why are we waiting for the input device to be opened by userspace before we do the switch instead of doing it immediately? == Several people (Simon Wood and Michal Maly) expressed the intent to work on proper HID switching in a short term.
