    [PATCH] ipmi: OEM flag handling and hacks for some Dell machines · 3ae0e0f9
    Corey Minyard 提交于
    The ipmi driver does not have a way to handle firmware-generated events
    which have the OEM[012] Data Available flags set.  In such a case, the
    SMS_ATN bit may never get cleared by firmware, leaving the driver looping
    infinitely but never able to make any progress.
    
    This patch first simplifies storage and use of the data returned from an
    IPMI Get Device ID command.
    
    It then creates a new per-OEM handler hook, which should know how to handle
    events with the OEM[012] Data Available flags set.  It then uses this to
    implement a workaround for IPMI 1.5-capable Dell PowerEdge servers which
    are susceptable to setting the OEM[012] Data Available flags when the
    driver can't handle it.
