    cyclictest: Align option fixes
    
    These changes make the align option truly optional as claimed.
    
    1. Rename disaligned to offset for readability.
    2. Fix the aligned option so that if no optional argument is given,
    the offset defaults to 0
    3. Fix some white space problems as reported by checkpatch.pl in the kernel

    cyclictest: add align thread wakeup times option
    
    This patch provides and additional -A/--align flag to cyclictest to align
    thread wakeup times of all threads as closly defined as possible.
    
    When running multiple threads in cyclictest (-S or -t # option) the threads
    are launched in an unsynchronized manner. Basically the creation order and
    time for thread creation determines the start time. For provoking a maximum
    congestion situation (e.g. cache evictions) and to improve reproducibility
    or run conditions the start time should be defined distances appart. The
    well defined distance is implemented as a offset parameter to -A/--align
    and will offset each threads start time by the parameter * the sequentially
    assigned thread number (par->tnum), together with the -d0 (distance in the
    intervals of the individual threads) this alignment option allows to get
    the thread wakeup times as closely synchronized as possible.
    
    The method to sync is simply that the thread with par->tnum == 0 is chosen
    to set a globally shared timestamp, and all other threads use this timestamp
    as their starting time rather than each calling clock_gettime() at startup.
    To ensure synchronization of the thread startup the setting of the global
    time is guarded by pthread_barriers.

    hackbench: init child's struct before using it
    
    Commit ad27df7 ("Reimplement better child tracking and improve error
    handling") changed the way of reporting pid/error after creating a
    child. It will return an union which is a mix pid_t, pthread_t and a
    signed long long for errors.
    Now on 32bit x86 both pid_t and pthread_t are four byte in size and are
    stored in the first 4 bytes. Now if the most significant bit of the long
    long variable happens to be set by chance (because nobody really
    initializes the variable here) then error variable will be negative. On
    little endian machines the assignment of pid or threadid won't reset the
    sign bit and you see this:
    
    | Running in process mode with 10 groups using 40 file descriptors each (== 400 tasks)
    | Each sender will pass 100 messages of 100 bytes
    | 0 children started.  Expected 40
    | sending SIGTERM to all child processes
    | signaling 0 worker threads to terminate
    | Creating workers (error: Success)
    
    A machine with proper endian handlig (that is big endian) would reset
    the sign bit during the assignment of pid and I would not have to make
    this patch :)
    
    While here, I make create_worker() since it is not used outside of this
    file.

    cyclictest: finish removal of 1 second first loops
    
    Huge latencies are observed (close to 1 second) when certain
    options are used in cyclictest.
    
    The problem was 1st introduced at commit da4956cbcaf7945554f
    ("use interval on first loop instead of 1 second").  It removed
    the 1 second first timing loop out of the main path in cyclictest
    but left it in two other paths, namely the ones triggered by
    these two options:
    
        -r   --relative    use relative timer instead of absolute
        -s   --system      use sys_nanosleep and sys_setitimer
    
    which in turn causes the huge latencies of close to 1 second to
    be reported by cyclictest with certain uses of those two options.
    
    Here we extend the original commit to remove the 1 second
    hardcoded timer values from the RELTIME and ITIMER options, by
    simply using the actual interval provided instead.

    Moreover be a bit more correct about CFLAGS/CPPFLAGS. Both should be

    CPPFLAGS taking options for the preprocessor. This is also needed for

    rt-tests / cyclictest: Make cyclictest fail if it cannot run with requested priority.
    
    Currently if a non-root user requests a priority higher than the soft limit in
    /etc/security/limits.conf
    the call to sched_setscheduler will silently fail and the user will be running
    with priority of 0. Cyclictest will not complain, and display the
    requested priority resulting in seemingly poor results.
    
    The following patch fixes this by doing two things.
    
    1. If the requested priority is higher than the soft limit but lower than the
    hard limit, it will raise the soft limit to the requested priority.
    
    2. If the requested priority is higher than the hard limit, it will fail with a
    warning.
    
    The patch should not affect privileged users.

    rt-tests: incorrect first latency value for --verbose option
    
    When the --verbose option is selected, the first value for each thread is
    incorrectly reported as zero.
    
    This is because when collecting the first value, the index into stat->values is
    incremented from zero to one before storing the value.  But when printing the
    values, the first value printed is stat->values[0], which has been initialized
    to zero.

    cyclictest problem/bug as non-root
    
    HI !
    
     minor bug in cyclictest but potential causing confusion on cyclictest
     resuults when running as non-root user.
    
    Setup:
     if one sets the rtprio in /etc/security/limits.conf to something below
     prio max - like:
    
     @hofrat          hard    rtprio          10
     @hofrat          soft    rtprio          10
    
     but then starts cylictest with -p 80 cyclictest will not fuss and also
     display priority 80 (as it uses par->prio in print_stat) but effectively
     runs with prio 0 as the return value of sched_setscheduler is not being
     checked in timerthread), resulting in semingly bad scheduling jitter values.
    
     So maybe cyclictest should take the effective maximum schduling priority
     of the user and not the scheduling policy maximum. Not sur if the check
     in timerthread is actually really needed - but it should not hurt ither.
     patch below (against current git) at "works for me" quality.
    
    thx!

    Only turn on ftrace_enabled if we're doing tracing that requires
    the function tracer. Don't turn it on for event-based tracing. Also,
    turn it off a the end of a run.

    do not touch tracing_thresh
    
    The -b argument is for stopping the cyclictest when it misses a wakup
    by that # microseconds. Setting the tracing_thresh causes the latency tracer
    to ignore any latency under tracing_thresh. These two meanings are completely
    agnostic to each other, and should not be the same. We want the max latency,
    that should be good enough. Not only those that are bigger than our missed
    deadline. That misses most of our traces that we want.

    allow events for all tracers
    
    Events are available for all tracers, including function and latency
    tracers. Do not treat them as a tracer. The -E option is agnostic to
    the tracer options, and if it is set, then events will be enabled for
    any tracer that is also set. If it is set by itself, then events will
    be enabled with the nop tracer.
    
    Also, the nop tracer is set before setting any of the tracers. This
    makes the nop tracer the default as well as clears out the trace before
    running the test.

    fix possible buffer overflow in string handling
    
    strncat writes up to n+1 chars when n is passed as 3rd argument.  So when
    doing
    	strncpy(filename, fileprefix, sizeof(filename));
    	strncat(filename, name, sizeof(filename) - strlen(fileprefix));
    
    with strlen(fileprefix) + strlen(name) >= sizeof(filename) a buffer
    overflow occurs.  Addionally there is no check if filename is big enough.
    
    So convert to memcpy and handle filename not being big enough.

    default cyclictest to SCHED_OTHER; clean up help message
    
    After much thought, I decided to keep cyclictest's default scheduling
    policy as SCHED_OTHER. My rationale is that if you don't specify a
    priority on the command line you get the priorityless policy. If you
    do specify a priority but no specific RT policy, we'll default to
    SCHED_FIFO. So to get SCHED_RR you have to specify priorty and policy
    name, for example:
    
    	# cyclictest --priority=90 --policy=rr
    
    Yes, I realize that the vast majority of users will run it with a
    realtime priority, but I just don't like picking a priority if it
    wasn't specified. If you want a realtime policy, specify a priority.

    the -T option (set tracer) option was missing a ':' for to indicate

    fix-policy-display-for-cyclictest.patch
    
    If the policy is forced to SCHED_OTHER, since the priority no longer
    fits into the SCHED_FIFO or SCHED_RR range, the policy display of
    cyclictest is somewhat incorrect.
    
    Display all policies.
    
    Also make the variable policystr static; the condition
    "if (!policystr)" is useless, otherwise.
    
    In addition, place the priority logic before decrementing the priority;
    a priority of 1 is incorrectly made SCHED_OTHER, otherwise.

    Revert "simplify equal priority logic for cyclictest"
    This reverts commit 582be2a52c43801a10d318de7491f1cc7243d5cf.
    
    Unfortunately this commit introduces a bug because the priority is not
    retested, and this can result in reported priorities below 0.
    For example,
    
    sudo ./cyclictest -t3 -p1
    policy: fifo: loadavg: 0.09 0.06 0.05 1/331 21732
    
    T: 0 (21730) P: 1 I:1000 C:    593 Min:     34 Act:  155 Avg:  100 Max:     672
    T: 1 (21731) P: 0 I:1500 C:    395 Min:     15 Act:   43 Avg:   72 Max:     853
    T: 2 (21732) P:-1 I:2000 C:    297 Min:     21 Act:   57 Avg:   79 Max:     330
    
    Notice that the last priority is reported as -1.
    
    After reverting this commit, we get the correct expected behaviour.
    
    sudo ./cyclictest -t3 -p1
    policy: fifo: loadavg: 0.07 0.05 0.04 2/330 21754
    
    T: 0 (21752) P: 1 I:1000 C:  11600 Min:     13 Act: 7072 Avg: 3593 Max:    7841
    T: 1 (21753) P: 0 I:1500 C:   7737 Min:     12 Act: 1572 Avg:  516 Max:    2381
    T: 2 (21754) P: 0 I:2000 C:   5804 Min:     12 Act:   53 Avg:   59 Max:     548
    
    I think it can be argued that the original code is also clearer, although
    that is somewhat subjective. With the original code I don't need to track
    down exactly what "sameprio" means, and it is clear what is being tested.

    Reimplement better child tracking and improve error handling
    
    This does much what earlier commits did before hackbench got updated
    to the latest version in the previous commit.

    Fix waitpid() implementation
    
    In commit 4c39eff2136c39b3c2746ca293eed5b5242aea52 a new approach for tracking
    each child was implemented.  But this implementation ignored the fact that each
    group() call creates 2*num_fds children.
    
    This patch refactors the previous attempt and will now track absolutely all
    children.  If fork() fails when called in group(), all spawned children will
    now also be killed explicitly.

    hackbench: Wait for each child explicitly by using waitpid()
    
    Quite often it's experienced in rteval that hackbench leaves some children
    as zombies during closure.  This is an attempt to keep an overview of the
    status of each child separately.  It's solved by having an array with all
    sender and reciever children's pids and calling waitpid() on each of these
    children pairs.

    [hwlatdetect] workaround for borken smi_detector.ko module
    
    Add a workaround to hwlatdetect to deal with a broken block of
    code in drivers/misc/smi_detector.ko, where whenever you enable
    the module (write a 1 to debugfs/smi_detector/enable) the stats
    initialization routine resets the threshold from whatever it was
    set to to 1us. This workaround checks the threshold after enabling
    the module and resets it to what we want.

    rt-tests: Add a new test pip - priority inheritance with processes
    
    This test is similar to pi_stress in that it purpursely triggers a priority-
    inversion. However, instead of using pthreads it uses processes.
    Since pthread_mutex_t are the only objects backed by priority inheritance
    this is accomplished by having the processes use a pthread_mutex_t in
    shared memory. See the header of pip.c for more information as well as the
    code of course.
    
    In addition this patch starts a src/include directory as a common place
    to put header files.

    - These changes also unify the Makefile, for example, every program

    - Due to the above change I had to make a number of changes in the programs
    that expected VERSION_STRING as a string.
    - By unifying what we CFLAGS, to include -D_GNU_SOURCE, I had to remove
    __USE_GNU which is reduncant in a number of files.

    rt-tests: pi_stress: Remove racy state variables that cause watchdog to trigger
    
    When using pthread_barrier_wait, it is important that barriers are called
    the correct number of times. That is - the same number given as the count
    when initializing the barrier.
    
    There was a do-while loop around elevate_barrier in the med priority thread.
    On most machines, it actually never looped.
    
    On threads with enough processors (nehelam for example), there was a racy
    situation in which the high priority thread could come out of the finish
    barrier, and before it could set high_has_run = 0, the medium priority
    thread would test the value and call the elevate barrier an extra time.

    Current cyclictest support FIFO policy for static priority of
    RT threads only. Append policy option to support FIFO or RR by user.
    
    After this patch.
    1) with FIFO about RT threads(default)
       ./cyclictest -t 5 -p 50
    or ./cyclictest -t 5 -p 50 -y 1
    or ./cyclictest -t 5 -p 50 --policy 1
    
    2) with RR about RT threads(default)
       ./cyclictest -t 5 -p 50 -y 2
    or ./cyclictest -t 5 -p 50 --policy 2
    
    This is screenshot of threads using cyclictest & tuna utility after patch.

    If we run a many threads with -t option, "priority--" rt priority will assign
    per thread in sequence. But, If we use -h option, all threads is same priority.
    
    Append man page and cyclictest usage about the same priority of many threads
    with -h option.
    
    ex) cyclictest -t 5 -p 50        [enter] <-- without -h
    ex) cyclictest -t 5 -p 50 -h 100 [enter] <-- with    -h

    Subject: Handle doomsday latency for cyclictest in histogram mode
    
    Don't miss latency which exceed the histogram limit -
    instead sample limit exceeding latency in the last bucket.
    
    This is a leftover from cyclictest_histogram.patch:
    -> Todo: Currently cyclictest does not report the number of samples
    -> that exceeded the histogram max latency.
    
    Handle OOM.

    Avoid segfault of cyclictest if it gets immediately interrupted.
    
    If clock_nanosleep() gets interrupted this could result in a negative
    time diff from calcdiff().
    
    With the histogram patch this leads to a segfault, since the time diff
    is used as index for the histogram array:
    
    Core was generated by `/usr/bin/cyclictest -n -q -p 99 -t 2 -i 500 -l
    1000000 -h
     20000'.
     Program terminated with signal 11, Segmentation fault.

        [PATCH] cyclictest: Add tracing function about wakeup and wakeup_rt of ftrace.
    
        This is patch to support wakeup & wakeup_rt tracing at the argument of
        cyclictest additionally. Current cyclictest support three tracing
        like PREEMPTOFF, IRQSOFF, PREEMPTIRQSOFF just.
    
        This additional function will help wakeup related tracing
        about sleep api [ex: nanosleep() , usleep] of cyclictest.
    
        Practically speaking, wakeup(+wakeup-rt) tracing by steven rostedt is useful
        in the linux based embedded product development.

        [PATCH] cyclictest: Remove duplicated description of cyclictest usage like -h.
    
        We often utilize a various options with "#>cyclictest --help" command in the terminal environment.
        When We run "#> cyclictest --help" command, We can show duplicated description about "-h" option
        for latency histogram.
        Unfortunatley, Some of the users is confusing because of two options about latency histogram.

                                   US is the max time to be be tracked in microseconds
    
        For example,
    
        -h H_MAX                   latency histogram size in us default 0 (off)
    
        -h       --histogram=US    dump a latency histogram to stdout after the run
                                   US is the max time to be be tracked in microseconds
    
        As you see, We don't need "-h H_MAX  . . . . . ." description.
        So, I think that We have to remove old option about description of histogram function.

        [patch] cyclictest: bugfix getopt_long() for -C and -F.
    
        We can not use -C option without --context option for tracing context switching.
        ex) ./cyclictest -t 10 -m -b 100 -C
        We can not use -E option without --event option for tracing events.
        ex) ./cyclictest -t 10 -m -b 100 -E
        Append -C and -E option on getopt_long() function to solve this problems.

    split function of DESTDIR into DESTDIR + prefix
    
    It's more common that DESTDIR doesn't include /usr or /usr/local but
    only the base directory for a relocated installation.  The in-tree
    prefix is usually named "prefix".
    
    "usually" here means as it is done by autoconf and as it is expected by
    the Debian package helpers.
    
    While at it also make the other path variables match this convention.

    reworked settracer()
    
    GeunSik Lim <leemgs1@gmail.com> found a problem with settracer()
    in that it had a hardcoded limit to the number of tracers searched.
    Unfortunately his patch found a bug in either fscanf or debugfs,
    since it doesn't seem to return EOF at the end of input, so I reworked
    the patch to read all the input and parse it using strtok.

    cyclictest: init tracer only once
    
    The tracer setup happens in every thread, which is nonsense. First of
    all it leads to a lot of irritating warnings because the things are
    setup multiple times. The worst effect is that one tasks runs already
    into the tracer stop condition and the next one reenables the tracer.
    
    Move the tracer setup into the main thread and do it only once.

    This patch has cyclictest work a bit better with ftrace. Some new options
    have been added.
    
    When -b is used:
    
      -P : use the preemptoff tracer
      -I : use the irqsoff tracer
      -B : use preemptirqsoff tracer
    
    If the above are not set, then it tries to use "events" tracer if it is
    available (currently only available in the -rt kernel) and if that is not
    set, it defaults to the sched-switch tracer.
    
    -f will enabled the function tracer.

    Fix the processing of optional options for cyclictest
    
    Problem: when running cyclic test, short options are not parsing
    optional arguments correctly when followed by a space.
    "-t3" works, but "-t 3" does not.
    
    - Fix the processing of options with optional parameters, so that the user
      can write -tNUM or -t NUM and it will work as expected. This was done
      for the -t and -a options
    
    - Modify the usage messages to correspond with the way the program makes use
      of the options.

    cyclictest: handle latest ftrace
    
    This patch has cyclictest work a bit better with ftrace. Some new options
    have been added.
    
    When -b is used:
    
      -P : use the preemptoff tracer
      -I : use the irqsoff tracer
      -B : use preemptirqsoff tracer
    
    If the above are not set, then it tries to use "events" tracer if it is
    available (currently only available in the -rt kernel) and if that is not
    set, it defaults to the sched-switch tracer.
    
    -f will enabled the function tracer.

    cyclictest: add -o option to reduce -v option's output speed
    
    When the output of the -v option is piped into another program and if
    more data are sent than the other program can eat, data points get
    lost. Since high latency values normally occur much less frequently
    than average latency values, the connected program will miss many of
    the high latency values, and the realtime capability of a given system
    may appear much better than it is.
    
    Therefore, the new option -o RED was introduced. This option causes
    cyclictest to suppress every subsequent RED number of samples and
    replace them with the maximum of the values encountered during that
    sampling interval.

    cyclictest: add CPU affinity
    
    Add CPU affinitt option to cyclictest.
    
    1. New option -a:
    
    without argument to a cyclictest spreads the threads consecutive on
    the available CPUs. On a quad core machine we get:
    
    -a -t4   Thread #0 -> CPU #0
             Thread #1 -> CPU #1
             Thread #2 -> CPU #2
             Thread #3 -> CPU #3
    
    -a -t5   Thread #0 -> CPU #0
             Thread #1 -> CPU #1
             Thread #2 -> CPU #2
             Thread #3 -> CPU #3
             Thread #4 -> CPU #0
    
    Adding a CPU number to the -a option all threads are pinned to
    the given CPU:
    
    -a3 -t4  Thread #0 -> CPU #3
             Thread #1 -> CPU #3
             Thread #2 -> CPU #3
             Thread #3 -> CPU #3
    
    2. extension of the -t option:
    
    Without argument to -t cyclictest starts as many threads as CPUs are
    available.

    This is a patch that's a ripple from the bug in signaltest that Luis and Jeff Burke

    uninitialized, depending on thread scheduling circumstances. Probably not major, but

    command line. We created a bugzilla ticket for this issue:
    
    	https://bugzilla.redhat.com/show_bug.cgi?id=308231
    
    After a few debug sessions we realized that a shared variable used to
    synchronize the work between threads, stat[i].threadstarted, could end up
    being used before initialization depending on the scheduling of the
    threads.
    
    The fix is a one-liner.
