2010-02-05Bluetooth: Keep a copy of each HID device's report descriptorMichael Poole
The report descriptor is read by user space (via the Service Discovery Protocol), so it is only available during the ioctl to connect. However, the HID probe function that needs the descriptor might not be called until a specific module is loaded. Keep a copy of the descriptor so it is available for later use.

2010-02-03HID: make raw reports possible for both feature and output reportsJiri Kosina
In commit 2da31939a42 ("Bluetooth: Implement raw output support for HIDP layer"), support for Bluetooth hid_output_raw_report was added, but it pushes the data to the intr socket instead of the ctrl one. This has been fixed by 6bf8268f9a91f1 ("Bluetooth: Use the control channel for raw HID reports") Still, it is necessary to distinguish whether the report in question should be either FEATURE or OUTPUT. For this, we have to extend the generic HID API, so that hid_output_raw_report() callback provides means to specify this value so that it can be passed down to lower level hardware drivers (currently Bluetooth and USB).

It's implemented to change behaviour in very tiny manner, so that no driver needs to be changed this time.

According to the bluetooth HID spec v1.0 chapter 7.4.2 "This code requests a major state change in a BT-HID device. A HID_CONTROL request does not generate a HANDSHAKE response." "A HID_CONTROL packet with a parameter of VIRTUAL_CABLE_UNPLUG is the only HID_CONTROL packet a device can send to a host. A host will ignore all other packets."

2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

2007-07-07Fix use-after-free oops in Bluetooth HID.David Woodhouse
When cleaning up HIDP sessions, we currently close the ACL connection before deregistering the input device. Closing the ACL connection schedules a workqueue to remove the associated objects from sysfs, but the input device still refers to them -- and if the workqueue happens to run before the input device removal, the kernel will oops when trying to look up PHYSDEVPATH for the removed input device. Fix this by deregistering the input device before closing the connections.

The current implementation of force feedback for HID devices is USB-transport only and therefore calling hid_ff_init() from hidp code is not going to work (plus it creates unwanted dependency of hidp on usbhid).

2007-03-29[PATCH] bluetooth hid quirks: mightymouse quirkJiri Kosina
I have a bugreport that scrollwheel of bluetooth version of apple mightymouse doesn't work. The USB version of mightymouse works, as there is a quirk for handling scrollwheel in hid/usbhid for it. Now that bluetooth git tree is hooked to generic hid layer, it could easily use the quirks which are already present in generic hid parser, hid-input, etc. Below is a simple patch against bluetooth git tree, which adds quirk handling to current bluetooth hidp code, and sets quirk flags for device 0x05ac/0x030c, which is the bluetooth version of the apple mightymouse.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it.
