  • cec854663   s390/css: stop stsch loop after cc 3 ... Browse Code »

    Receiving cc=3 from store subchannel means 2 things:
    * the subchannel is not provided
    * there are no further subchannels in this subchannel set

    With this patch we abort the store subchannel loop after cc=3 (or an
    exception) and clear the subsequent bits in the subchannel id set.

  • a53c8fab3   s390/comments: unify copyright messages and remove file names ... Browse Code »

    Remove the file name from the comment at top of many files. In most
    cases the file name was wrong anyway, so it's rather pointless.

    Also unify the IBM copyright statement. We did have a lot of sightly
    different statements and wanted to change them one after another
    whenever a file gets touched. However that never happened. Instead
    people start to take the old/"wrong" statements to use as a template
    for new files.
    So unify all of them in one go.

  • 9d92a7e1b   [S390] cio: Add chsc subchannel driver. ... Browse Code »

    This patch adds a driver for subchannels of type chsc.

    A device /dev/chsc is created which may be used to issue ioctls to:
    - obtain information about the machine's I/O configuration
    - dynamically change the machine's I/O configuration via
    asynchronous chsc commands

  • 83b3370c7   [S390] cio: replace subchannel evaluation queue with bitmap ... Browse Code »

    Use a bitmap for indicating which subchannels require evaluation
    instead of allocating memory for each evaluation request. This
    approach reduces memory consumption during recovery in case of
    massive evaluation request occurrence and removes the need for
    memory allocation failure handling.
