    [PATCH] ipmi: add power cycle capability · 3b625943
    Corey Minyard authored
    This patch to adds "power cycle" functionality to the IPMI power off module
    ipmi_poweroff.  It also contains changes to support procfs control of the
    feature.
    
    The power cycle action is considered an optional chassis control in the IPMI
    specification.  However, it is definitely useful when the hardware supports
    it.  A power cycle is usually required in order to reset a firmware in a bad
    state.  This action is critical to allow remote management of servers.
    
    The implementation adds power cycle as optional to the ipmi_poweroff module.
    It can be modified dynamically through the proc entry mentioned above.  During
    a power down and enabled, the power cycle command is sent to the BMC firmware.
     If it fails either due to non-support or some error, it will retry to send
    the command as power off.
