Subject: [PATCH] cyclictest: Fix setaffinity error on large NUMA machines
An Error occurs when run: ./cyclictest -v -t 5 -p 80 -i 1000 -a 3
On large NUMA machines still getting the following error
WARN: Couldn't setaffinity in main thread: Invalid argument
Instead of calling numa_bitmask_alloc() with max_cpus, use
numa_allocate_cpumask() to fix this.
Also, make sure numa_available() is called before any other calls to the
numa library. Depending on how the options were invoked this could
happen in parse_cpumask for example. Note, this did not seem to cause
any problems in practice, but let's adhere to the library contract.

Subject: [PATCH] pi_stress: limit the number of inversion groups to the number
of online cores
Each inversion group is three SCHED_FIFO threads, so the chances of more groups
than online cores actually getting to run is very slim. Limit the number of
groups requested to be <= the number of online cpus.
Signed-off-by: Clark Williams <williams@redhat.com>
Changing the conversion in printf to %ld since the number of online
processors is a long.

Subject: [PATCH 1/8] rt-tests: Set affinity before applying numa
There are three changes here.
1. If affinity is not specified, but numa is available, then numa
implies AFFINITY_USEALL.
2. Move setting affinity before applying numa
We need to set the affinity before applying numa, so that we don't
apply numa settings to cpus we don't intend to run on.
3. Allow a greater number of threads than cpus to run in a round robin
fashion in the case of numa.

This doesn't prevent people from defining it as version 1, or compiling

Subject: [PATCH 5/8] rt-tests: cyclictest: Don't allow OPT_SYSTEM with
OPT_POSIX_TIMERS
OPT_SYSTEM means use sys_nanosleep and sys_setitimer
if you try to combine it with OPT_POSIX_TIMERS, it breaks.
cyclictest becomes unkillable with ctrl-C and only the first thread is
updated.
Fix this by issuing a warning if the user tries to combine the two
options and then use clock_nanosleep.

Fix warning 'cpu' maybe uninitialized by giving it a default value in
the switch statement. Note, this is a false positive, but documenting
the default value in the switch statement isn't a bad thing.

Subject: [PATCH] rt-tests: cyclictest: Get a snapshot of cyclictest without
interuppting it
Right now if you are running cyclictest you can send it SIGUSR1
and it will spill out the data at a moment in time, and keep running.
However, this can be problematic if you are using another program such
as rteval to consume the data.
This feature here lets you send SIGUSR2 to cyclictest and it dumps
status to shared memory so you can read it without interrupting
cyclictest and without interferring with the data it is outputing.
To use it, start cyclictest in one term, then in another term send it
SIGUSR2, and then you can just cat the results like this:

Subject: [PATCH 8/8] rt-tests: cyclictest: Just use LIBNUMA_API_VERSION 2
This removes support for LIBNUMA_API_VERSION 1.
You can still build without numa support by doing
make NUMA=0
You can also build with numa and run on machines without numa support.

Subject: [PATCH] rt-tests: cyclictest: Make tracemark work correctly again
commit f5ccfbe4d6641e48f56152be135d901dd31cba7e
was a little too aggressive removing ftrace code.
We were able to remove ftrace code because this functionality is
available using trace-cmd, in conjunction with the tracemark option in
cyclictest. Put back the parts of tracemark needed to make this work
correctly.
After this patch you can get tracing info like this as an example.
trace-cmd record -p function ./cyclictest -t -b100 --tracemark

Subject: [PATCH 1/2] rt-tests: cyclictest: Move ftrace helpers into
rt-utils.[ch]
Then they can be further used by other programs too.
Two trivial things to mention.
Firstly, move trace_marker out of enable_trace_mark(). No functional change.
Secondly, remove the fileprefix setting in process_options(), because if
tracelimit is non-zero, fileprefix will be after all replaced by a further call
to get_debugfileprefix() in debugfs_prepare().

Subject: [PATCH 4/5] rt-tests: determine_maximum_mpps.sh: Fix quoting and
other shell issue
Fix a number of issues in the script determine_maximum_mpps.sh such as
1. Convert legacy backticks to $(...) notation
2. Double quote where necessary to prevent globbing
3. Double quote where necessary to prevent word splitting.
Note: these fixes are more than just cosmetic, they are needed for the
script to work correctly.

Subject: [PATCH 5/5] rt-tests: queuelat: get_cpuinfo_mhz.sh highest value
get_cpuinfo_mhz.sh greps for the Mhz from the /proc/cpuinfo file
It assumes that for multiple cpus the value will be the same, and
intends to return one value using uniq as a filter.
Typically the reported Mhz values can all be slightly different though
It would probably be good enough to simply take the first match as a
heuristic, but to be safe, take the highest number.
Also replace the legacy backticks with the modern $(...) construct, and
quote the $mhz variable.

Subject: [PATCH] svsematest: Add -S, --smp option to manpage
The -S, or --smp option is in the help but missing from the manpage.
We should really revisit these tests as these options have changed a bit
in cyclictest and they are all modeled after cyclictest.
