* Input: atkbd - add 'terminal' parameter for IBM Terminal keyboardsBenjamin LaHaise2010-11-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Many of the IBM Terminal keyboards from the 1980s and early 1990s communicate using a protocol similar, but not identical to the AT keyboard protocol. (Models known to be like this include 6110344, 6110668, 1390876, 1386887, and possibly others.) When the connector is rewired or adapter to an AT-DIN or PS/2 connector, they can be connected to a standard PC, with three caveats: a) They can only use scancode set 3; requests to use anything else are quietly ignored. b) The AT Command to request Make, Break and Repeat codes is not properly interpreted. c) The top function keys on a 122 key keyboard, and the arrow/edit keys in the middle of the board send non-standard scancodes. C) is easily taken care of in userspace, by use of setkeycodes B) can be taken care of by a userspace hack (that makes the kernel complain in dmesg) A) is fixable in theory, but on the keyboard i tested on (6110668), it seems to be detected unoverridably as Set 2, causing userspace oddities that make it harder to fix C). Enclosed is a small patch to the kernel that fixes A) and B) in the kernel, making it much easier to fix C) in userspace. It adds a single kernel command line parameter that overrides the detection that sets these boards as set 2, and instead of sending the Make-break-repeat command to the keyboard, it sends the make-break command, which is properly recognized by these keyboards. Software level key repeating seems to make up for the lack of hardware repeat codes perfectly. Without manually setting the command line parameter (tentatively named atkbd.terminal), this code has no effect, and the driver works exactly as before.

* Input: atkbd - release previously reserved keycodes 248 - 254Dmitry Torokhov2010-02-26
| | | | | | | | | | | Keycodes in 248 - 254 range were reserved for special needs (scrolling) of atkbd driver. Now that the driver has been switched to use unsigned short keycodes instead of unsigned char we can release this range back into pull. We keep code 255 (ATKBD_KEY_NULL) reserved since users may have been using it to silence keys they do not care about since atkbd silently drops scancodes mapped to this keycode.

| * Input: serio - fix potential deadlock when unbinding driversEric W. Biederman2010-01-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | sysfs_remove_group() waits for sysfs attributes to be removed, therefore we do not need to worry about driver-specific attributes being accessed after driver has been detached from the device. In fact, attempts to take serio->drv_mutex in attribute methods may lead to the following deadlock: sysfs_read_file() fill_read_buffer() sysfs_get_active_two() psmouse_attr_show_helper() serio_pin_driver() serio_disconnect_driver() mutex_lock(&serio->drv_mutex); <--------> mutex_lock(&serio_drv_mutex); psmouse_disconnect() sysfs_remove_group(... psmouse_attr_group); .... sysfs_deactivate(); wait_for_completion(); Fix this by removing calls to serio_[un]pin_driver() and functions themselves and using driver-private mutexes to serialize access to attribute's set() methods that may change device state.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OQO 01+ multimedia keys produce 6x on press, e0 6x upon release. As a result, Linux thinks that another key has been pressed (or is repeating), when it is actually a release of the same key. Mangle the release scancode when running on OQO so that driver recognizes it as such. Since the device does not have external PS/2 ports mangling is safe since there is no chance that an external keyboard is connected.

* | | Input: atkbd - postpone restoring LED/repeat rate at resumeDmitry Torokhov2009-10-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We need to postpone restoring LED state and typematic settings until keyboard is finished reconnecting upon resume. Normally driver core and PM infrastructure takes care of proper ordering and dependencies, but or case actual reconnect is done asynchronously from kseriod. So while driver core thinks that keyboard was resumed and it is time to let input core run it's resume handlers in reality keyboard is not ready yet. The solution is to keep rescheduling work that adjusts LED and rate settings until keyboard is fully enabled. Reported-by: Carlos R.

| * Input: atkbd - allow setting force-release bitmap via sysfsDmitry Torokhov2009-09-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are more and more laptop requiring use of force_release quirk for their multimedia and other specialized keys. Adding their DMI data to the kernel is not sustainable; instead we will rely on help from userspace (HAL) to do that for us. This patch creates a new 'force_release' sysfs attribute (that belongs to serio device to which keyboard is attached) which can be used to set up force_release keymap. For example, Dell laptop owners might do: echo 133-139,143,147 > /sys/devices/platform/i8042/serio0/force_release Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
