    [PATCH] Driver for IBM service processor - updated (1/2) · 81e38ceb
    Max Asbock authored
    Here is a device driver for the IBM xSeries RSA service processor.
    The ibmasm driver is mainly intended to be used in conjunction with a user space
    API and systems management applications that need to get in-band access to
    the service processor, such as sending commands or waiting for events.
    For the remote video feature the driver relays remote mouse and keyboard
    events to user space.
    By itself the driver also allows the OS to make use the UART on the service
    processor board as a regular serial line.
    
    The user interface to the driver is a custom file system. It does not use sysfs since
    the operations on the files are somewhat beyond the one file / one value rule for sysfs.
    Since it is not strictly a char driver I put it into the drivers/misc directory.
    
    The patch is fairly big, therefore I split it up into the file system part and the
    everything-else part.
    
    Here is the non-filesystem part:
