Supported: Someone is actually paid to look after this.
17+
Maintained: Someone actually looks after it.
18+
Odd Fixes: It has a maintainer but they don't have time to do
19+
much other than throw the odd patch in. See below..
20+
Orphan: No current maintainer [but maybe you could take the
21+
role as you write your new code].
22+
Obsolete: Old code. Something tagged obsolete generally means
23+
it has been replaced by a better system and you
24+
should be using that.
25+
F: Files and directories with wildcard patterns.
26+
A trailing slash includes all files and subdirectory files.
27+
F: drivers/net/ all files in and below drivers/net
28+
F: drivers/net/* all files in drivers/net, but not below
29+
F: */net/* all files in "any top level directory"/net
30+
One pattern per line. Multiple F: lines acceptable.
31+
X: Files and directories that are NOT maintained, same rules as F:
32+
Files exclusions are tested before file matches.
33+
Can be useful for excluding a specific subdirectory, for instance:
34+
F: net/
35+
X: net/ipv6/
36+
matches all files in and below net excluding net/ipv6/
37+
K: Keyword perl extended regex pattern to match content in a
38+
patch or file. For instance:
39+
K: of_get_profile
40+
matches patches or files that contain "of_get_profile"
41+
K: \b(printk|pr_(info|err))\b
42+
matches patches or files that contain one or more of the words
43+
printk, pr_info or pr_err
44+
One regex pattern per line. Multiple K: lines acceptable.
45+
46+
Note: For the hard of thinking, this list is meant to remain in alphabetical
47+
order.

CPU Load Generator
8+
9+
10+
ABOUT:
11+
------
12+
13+
CPULOADGEN is a Linux user-space standalone application designed to provide a
14+
quick'n easy way to generate programmable load on CPU core(s).
15+
16+
To generate load, it reuses DHRYSTONE loops, applying on top of it sort of
17+
PWM (Pulse Width Modulation) principle: by generating active (100% load) and
18+
idle (0% load) with programmable duty cycle,
19+
it generates an average CPU load of [1-100]%.
20+
.
21+
22+
23+
SUPPORT:
24+
--------
25+
CPULOADGEN is a generic application, it can run on any CPU architecture.
26+
27+
Please note however that application development is still under progress,
28+
so currently it can only generates loads on mono or dual-core architectures
29+
(extra cores will not be handled). This will be improved to address any number of
30+
CPU cores in the future.
31+
32+
33+
THIS SOFTWARE IS PROVIDED AS IS, WITH NO SUPPORT OR MAINTENANCE COMMITMENT FROM
34+
TEXAS INSTRUMENTS INCORPORATED.
35+
36+
37+
38+
Build instructions:
39+
-------------------
40+
To only build the output binary file:
41+
42+
# make cpuloadgen
43+
44+
NB: CROSS_COMPILE variable must be set to point to the correct compiler.
45+
E.g: (for ARM architecture)
46+
47+
# export CROSS_COMPILE=arm-none-linux-gnueabi-
48+
49+
or
50+
51+
# make CROSS_COMPILE=arm-none-linux-gnueabi- cpuloadgen
52+
53+
54+
To build and install cpuloadgen:
55+
56+
# make DESTDIR=<YOUR_DIR> install
57+
58+
<YOUR_DIR> is a destination directory where cpuloadgen output binary file will be
59+
installed (copied, e.g. ubuntu/android filesystem).
60+
61+
That's it!
62+
63+
64+
65+
Usage:
66+
-----
67+
68+
cpuloadgen [<cpu0load>] [<cpu1load>] [<duration>]
69+
<cpu0load>: CPU load to be generated on CPU0 (in %) [1-100]
70+
<cpu1load>: CPU load to be generated on CPU1 (in %) [1-100]
71+
<duration>: test duration (in seconds) [0-600]
72+
73+
If <duration> is omitted, then it runs until CTRL+C is pressed.
74+
If <duration> & <cpu1load> are omitted, then it generates <cpu0load> load on any
75+
available CPU until CTRL+C is pressed (no affinity, scheduler runtime decision).
76+
If all options are omitted, then it runs until CTRL+C is pressed with
77+
a 100% CPU Load on each core.
