  • 156f5a780   debugfs: Fix terminology inconsistency of dir name to mount debugfs filesystem. ... Browse Code »

    Many developers use "/debug/" or "/debugfs/" or "/sys/kernel/debug/"
    directory name to mount debugfs filesystem for ftrace according to
    ./Documentation/tracers/ftrace.txt file.

    And, three directory names(ex:/debug/, /debugfs/, /sys/kernel/debug/) is
    existed in kernel source like ftrace, DRM, Wireless, Documentation,
    Network[sky2]files to mount debugfs filesystem.

    debugfs means debug filesystem for debugging easy to use by greg kroah
    hartman. "/sys/kernel/debug/" name is suitable as directory name
    of debugfs filesystem.
    - debugfs related reference: http://lwn.net/Articles/334546/

    Fix inconsistency of directory name to mount debugfs filesystem.

    * From Steven Rostedt
    - find_debugfs() and tracing_files() in this patch.

    The function graph tracer is called just "function_graph" (no trailing
    "_tracer" needed).

  • 294ae4011   ftrace: fix typo about map of kernel priority in ftrace.txt file. ... Browse Code »

    Fix typo about chart to map the kernel priority to user land priorities.

    * About sched_setscheduler(2)
    Processes scheduled under SCHED_FIFO or SCHED_RR
    can have a (user-space) static priority in the range 1 to 99.
    (reference: http://www.kernel.org/doc/man-pages/online/pages/
    man2/sched_setscheduler.2.html)

    * From: Steven Rostedt
    0 to 98 - maps to RT tasks 99 to 1 (SCHED_RR or SCHED_FIFO)

    99 - maps to internal kernel threads that want to be lower than RT tasks
    but higher than SCHED_OTHER tasks. Although I'm not sure if any
    kernel thread actually uses this. I'm not even sure how this can be
    set, because the internal sched_setscheduler function does not allow
    for it.

    100 to 139 - maps nice levels -20 to 19. These are not set via
    sched_setscheduler, but are set via the nice system call.

    140 - reserved for idle tasks.

    - fix some typos
    - document the difference between '>' and '>>'
    - document the 'enable' toggle
    - remove section "Defining an event-enabled tracepoint", since it's
    out-dated and sample/trace_events/ already serves this purpose.

    v2: add "Updated by Li Zefan"

    [ Impact: make documentation up-to-date ]

  • 66bb74888   tracing: consolidate documents ... Browse Code »

    Move kmemtrace.txt, tracepoints.txt, ftrace.txt and mmiotrace.txt to
    the new trace/ directory.

    I didnt find any references to those documents in both source
    files and documents, so no extra work needs to be done.
