  • 669f6f96c   Documentation/features: Explain kernel feature descriptions and add visualization script ... Browse Code »

    The previous patches added arch support matrices for more than 40 generic kernel features
    that need per architecture support.

    The structure of the feature descriptions is the following:

    Each feature has its own directory under Documentation/features/subsystem_name/feature_name/,
    and the arch-support.txt file shows its current arch porting status.

    For example, lockdep support is shown the following way:

    triton:~/tip> cat Documentation/features/locking/lockdep/arch-support.txt
    #
    # Feature name: lockdep
    # Kconfig: LOCKDEP_SUPPORT
    # description: arch supports the runtime locking correctness debug facility
    #
    -----------------------
    | arch |status|
    -----------------------

    | um: | ok |
    | unicore32: | ok |
    | x86: | ok |
    | xtensa: | ok |
    -----------------------

    For generic kernel features that need architecture support, the
    arch-support.txt file in each feature directory shows the arch
    support matrix, for all upstream Linux architectures.

    The meaning of entries in the tables is:

    | ok | # feature supported by the architecture
    |TODO| # feature not yet supported by the architecture
    | .. | # feature cannot be supported by the hardware

    This directory structure can be used in the future to add other
    files - such as porting guides, testing description, etc.

    The Documentation/features/ hierarchy may also include generic
    kernel features that works on every architecture, in that case
    the arch-support.txt file will list every architecture as
    supported.

    To list an architecture's unsupported features, just do something
    like:

    triton:~/tip> git grep -lE 'x86.*TODO' Documentation/features/*/*/arch-support.txt
    Documentation/features/lib/strncasecmp/arch-support.txt
    Documentation/features/time/arch-tick-broadcast/arch-support.txt

    which will print the list of not yet supported features.

    The Documentation/features/list-arch.sh script will print the current
    support matrix of one architecture:

    triton:~/tip> Documentation/features/list-arch.sh
