From 1c1e40b5ad6e345feba69bc612db006efccf4cdc Mon Sep 17 00:00:00 2001 From: Florian Festi Date: Thu, 14 Dec 2006 11:59:11 +0100 Subject: input/hid: Supporting more keys from the HUT Consumer Page On USB keyboards lots of hot/internet keys are not working. This patch adds support for a number of keys from the USB HID Usage Table (http://www.usb.org/developers/devclass_docs/Hut1_12.pdf). It also adds several new key codes. Most of them are used on real world keyboards I know. I added some others (KEY_+ EDITOR, GRAPHICSEDITOR, DATABASE, NEWS, VOICEMAIL, VIDEOPHONE) to avoid "holes". I also added KEY_ZOOMRESET as it is possible to have a inet keyboard and a remote control in parallel and it makes sense to have them behave differently.

The reason for this is, that before the reboot is done, the channel subsystem is shut down. During the reset on each possible subchannel a "store subchannel" is done. This operation can end in a program check interruption, if the specified subchannel set is not implemented by the hardware. During the reset, currently we do not have a program check handler, which leads to the described kernel bug. We install now a new program check handler for the reboot code to fix this problem.

So we need to serialize the assignment with the locks on those architectures (notably older ARM chips, PA-RISC and sparc32). So rather than using an "unsigned long", let's use "atomic_long_t", which already has a safe assignment operation (atomic_long_set()) on such architectures. This requires that the atomic operations use the same atomicity locks as the bit operations do, but that is largely the case anyway. Sparc32 will probably need fixing. Architectures (including modern ARM with LL/SC) that implement sane atomic operations for SMP won't see any of this matter.
