From d7a7671477710eca0673a54475b47a58dbf44842 Mon Sep 17 00:00:00 2001

Subject: [PATCH 1/2] CLI: start a process from tuna
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Currently it is possible to set the CPU affinity and sched tunables for
threads running on a system. However, tuna does not permit to start a
new application with these parameters set.

This patch adds the ability to start a new process with its affinity
and sched tunable set before it starts to run.

To do so, one parameter was added to tuna's command line. This
parameter is the Action -r, --run=:

-r, --run="COMMAND"
Run the COMMAND. If arguments are passed, the entire com‐
mand line must be provided inside "quotes". Modifiers -c
and -p can be used to set the affinity and scheduler tun‐
ables of the given COMMAND. The arg[0] (i.e. the command)
will be set in THREAD-LIST. Likewise the -t, the COMMAND
accepts the prefix + and - as wildcards in order to be
appended or removed from THREAD-LIST, respectively.

The option -r will fork a new process, set the sched tunables and
affinity, and execute the new application's binary.

Tuna will wait for the new process to return, and then continue
its execution. That means that it is possible to execute many Actions
after the creation of a new process, including the start of many process
in a single command line.

Example of use:

[root@kiron tuna]# tuna -p fifo:1 -t bash -c 1,2 -r +httpd -P
thread ctxt_switches
pid SCHED_ rtpri affinity voluntary nonvoluntary cmd
10550 OTHER 0 0,1,2,3 300 81 bash
12898 OTHER 0 0,1,2,3 30 6 bash
12930 OTHER 0 0,1,2,3 246 27 bash
13022 FIFO 1 1,2 1 0 httpd

In this example, the schedule policy:prio fifo:1 is saved for future
Actions, "bash" is set in Thread list, cpus 1,2 are set in the cpulist,
the command "httpd" is appended to the Thread list and is started.
Finally, the threads in Thread list are printed.

From e9a4bc14e15115e3493781fe8487fb4bd575ae9e Mon Sep 17 00:00:00 2001

Subject: [PATCH] tuna: tuna-cmd: Display usage instead of traceback -c missing
args

Display a usage messaage instead of a python traceback when a required
argument to the -c or --cpus is missing, or when the argument doesn't
make sense. (Such as passing a nonsense string, instead of a comma separated list of numbers)

- In function pick_op, handle the unusual but possible case where an
empty string is passed as an argument.
- Display a usage message upon ValueError when caling cpustring_to_list
when processing the -c option

This fixes various erroneous or missing input to -c, such as the
following

./tuna-cmd.py -c -P
Traceback (most recent call last):
File "./tuna-cmd.py", line 656, in <module>
main()
File "./tuna-cmd.py", line 494, in main
op_list = tuna.cpustring_to_list(a)
File "/home/jkacur/source/tuna/tuna/tuna.py", line 124, in
cpustring_to_list
ends = [ int(a, 0) for a in field.split("-") ]
ValueError: invalid literal for int() with base 0: 'P'

File "./tuna-cmd.py", line 408, in pick_op
if argument[0] in ('+', '-'):
IndexError: string index out of range

./tuna-cmd.py -c "nonesense" -P
Traceback (most recent call last):
File "./tuna-cmd.py", line 656, in <module>

cpustring_to_list
ends = [ int(a, 0) for a in field.split("-") ]
ValueError: invalid literal for int() with base 0: 'nonesense'

This fixes bugzilla 1268287

Subject: [PATCH 2/2] docs: upgrade tuna.8 man page with option -r
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update tuna.8 man page with the descriptions of the new command line
options:
-r, --run="COMMAND"
Run the COMMAND. If arguments are passed, the entire com‐
mand line must be provided inside "quotes". Modifiers -c
and -p can be used to set the affinity and scheduler tun‐
ables of the given COMMAND. The arg[0] (i.e. the command)
will be set in THREAD-LIST. Likewise the -t, the COMMAND
accepts the prefix + and - as wildcards in order to be
appended or removed from THREAD-LIST, respectively.

And the modifications of -p behavior:
-p, --priority=[POLICY:]RTPRIO
Set thread scheduler tunables: POLICY and RTPRIO. POLICY
is one of OTHER, FIFO, RR, or BATCH. If -t is not set, -p
will act as a Modifier, saving the sched tunables for
future Actions, for example -r.

And -t behavior:
-t, --threads=THREAD-LIST
THREAD-LIST affected by commands. Requires a thread num‐
ber or thread name, or a comma-separated list of thread
numbers and/or names. Thread names may contain wildcards.
Be sure to quote or escape any wildcard specifications.
If only - is passed as argument, the THREAD-LIST will be
cleared.

Subject: [PATCH] tuna: cpuview.py: Omit offline cpus in socket_ids list

sysfy.py inserts None for offline cpus in class cpus, method reload, via
class cpu method reload.

This is potentially useful, so we don't want to change these classes.
However in cpuview.py - class cpuview, we don't want to display these
offline cpus, so we only need to recognize that the type None can be
returned and then skip over it.

This fixes Bugzilla 1036156

%description
Provides interface for changing scheduler and IRQ tunables, at whole CPU and at
per thread/IRQ level. Allows isolating CPUs for use by a specific application
and moving threads and interrupts to a CPU by just dragging and dropping them.
Operations can be done on CPU sockets, understanding CPU topology.

Can be used as a command line utility without requiring the GUI libraries to be
installed.

%description -n oscilloscope
Plots stream of values read from standard input on the screen together with
statistics and a histogram.

Allows to instantly see how a signal generator, such as cyclictest, signaltest
or even ping, reacts when, for instance, its scheduling policy or real time
priority is changed, be it using tuna or plain chrt & taskset.
