Input: sysrq - request graceful shutdown for key reset

2013-06-06T19:03:58Z

Attempt to reboot the system gracefully when a key combo is detected. If the reste combination is pressed the 2nd time we assume that graceful reboot failed and perform emergency reboot. This fucntionality is useful when UI is stuck but the system is otherwise working fine. Signed-off-by: Mathieu Poirier Signed-off-by: Dmitry Torokhov

tty: replace strict_strtoul() with kstrtoul()

2013-06-03T17:30:42Z

The usage of strict_strtoul() is not preferred, because strict_strtoul() is obsolete. Thus, kstrtoul() should be used. Signed-off-by: Jingoo Han Signed-off-by: Greg Kroah-Hartman

Input: sysrq - supplement reset sequence with timeout functionality

2013-04-02T05:22:19Z

Some devices have too few buttons, which it makes it hard to have a reset combo that won't trigger automatically. As such a timeout functionality that requires the combination to be held for a given amount of time before triggering is introduced. If a key combo is recognized and held for a 'timeout' amount of time, the system triggers a reset. If the timeout value is omitted the driver simply ignores the functionality.

sysrq: fix inconstistent help message of sysrq key

2013-03-15T21:06:45Z

Currently help message of /proc/sysrq-trigger highlight its upper-case characters, like below: SysRq : HELP : loglevel(0-9) reBoot Crash terminate-all-tasks(E) memory-full-oom-kill(F) kill-all-tasks(I) ... this would confuse user trigger sysrq by upper-case character, which is inconsistent with the real lower-case character registed key. This inconsistent help message will also lead more confused when 26 upper-case letters put into use in future. This patch fix it. Thanks the comments from Andrew and Randy.

sysrq: don't depend on weak undefined arrays to have an address that compares as NULL

2013-02-27T17:59:50Z

When taking an address of an extern array, gcc quite naturally should be able to say "an address of an object can never be NULL" and just optimize away the test entirely. However, the new alternate sysrq reset code (commit 154b7a489a5b: "Input: sysrq - allow specifying alternate reset sequence") did exactly that, and declared platform_sysrq_reset_seq[] as a weak array, and expecting that testing the address of the array would show whether it actually got linked against something or not. And that doesn't work with all gcc versions. Clearly it works with *some* versions of gcc, and maybe it's even supposed to work, but it really is a very fragile concept. So instead of testing the address of the weak variable, just create a weak instance of that array that is empty. If some platform then has a real platform_sysrq_reset_seq[] that overrides our weak one, the linker will switch to that one, and it all works without any run-time conditionals at all.
