From 04561c5aa243c98cae93cde27e05740df787e692 Mon Sep 17 00:00:00 2001 From: Ignaz Forster Date: Mon, 1 Nov 2010 15:13:37 -0400 Subject: HID: Add Force Feedback support for EMS Trio Linker Plus II The device has connections for GameCube, PlayStation 2 and Dreamcast controllers, however Force Feedback is only supported for PS2 and GC controllers. When using a PS2 controller it may be necessary to press the "Analog" button to enable support for both motors (this behavior is identical to the Windows driver, I have found no way to avoid that).

If this happens right before or while hiddev_ioctl is in progress, the hiddev_ioctl tries to access invalid hiddev->hid pointer. When the hid device is disconnected, the hiddev_disconnect() ends up with a call to hid_device_release() which frees hid_device, but doesn't set the hiddev->hid pointer to NULL. If the deallocated memory region has been re-used by the kernel, this can cause a crash or memory corruption. Since disconnect can happen at any time, we can't initialize struct hid_device *hid = hiddev->hid at the beginning of ioctl and then use it. This change checks hiddev->exist flag while holding the existancelock and uses hid_device only if it exists.

If it's removed while hiddev_ioctl() is in progress, some commands are still processed fine, others return -ENODEV. This change takes the "existancelock" before processing ioctl commands and releases it at the end. If the device has been removed, always returns -ENODEV.

This would be fine in the normal mode, but the driver puts the device in multitouch mode where no relative events are generated. Also, userspace software depends on accurate axis information for device type detection. Thus, ignoring the relative axes from the Magic Trackpad is best.

The device has 2 modes. The first one is an emulation of a touchscreen by sending left and right button, and the second mode is the one used in dual-touch (sending trackingID, touch and else). That's why there is a hid report containing left and right buttons (9000001 and 9000002). The point is that xorg relies on these fields to determine if it's a touchpad or a touchscreen. Clearing the report (return -1) makes xorg detecting it out of the box as a quite pleasant (dual)touchscreen.

The driver generates virtual files "red", "green", and "blue" under the device's /sys/ directory, where color values can be read from and written to. This patch adds support for Dream Cheeky's "DL100B Webmail Notifier" (http://www.dreamcheeky.com/webmail-notifier -- available from several shops, such as http://www.conrad.at/ce/de/product/777048/USB-WEBMAIL). This device isn't as pretty as Delcom's, but it's *far* cheaper, and its 3 LEDs can be set in 32 brightness steps each. The grey envelope contour can easily be removed, leaving a rather neutral white box (with a few small holes), which is useful for generic signalling purposes. Of course, the small circuit board can easily be put into a prettier case. The DL100B device pretends to be a HID, but the HID descriptor shows that it's not overly useful as such (see below). The patch therefore removes the "HID-ness" (hid-core.c, hid-ids.h), and adds the necessary commands to usbled.c. The protocol info comes from the developer's manual that Dream Cheeky kindly provided (815DeveloperManual.pdf).

Some information can be really important in such features: MosArt and Cypress devices are by default not in a multitouch mode. We have to send the value 2 on the right feature. This patch exports to the module the features report so they can find the right feature to set up the correct mode.

the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.
