This commits an initial version of the Memorizer tracing tool. It collects and outputs detailed data on the objects (traced from kmalloc/kmem_cache_alloc) and accesses, tracking the context of each event with respect to thread ID, program counter, and for allocations name of process.

Dependencies:
|
|
In order to run the test_memorizer w/ linux test suite, you must
|
|
wget the latest version from the ltp github repo and set it up.
|
|
Ex:
|
|
wget https://github.com/linux-test-project/ltp/releases/download/20170116/ltp-full-20170116.tar.bz2
|
|
tar xvfj ltp-full-20170116.tar.bz2
|
|
# cd into the untarred dir
|
|
./configure
|
|
make
|
|
sudo make install
|
|
|
|
Good documentation / examples: http://ltp.sourceforge.net/documentation/how-to/ltp.php
|
|
|
|
memorizer.py: accepts processes to run in quotes.
|
|
Ex: python memorizer.py "ls" "mkdir dir"
|
|
In order to run the script, you must have your user be in the
|
|
memorizer group, which you should setup if not.
|
|
How-to: sudo groupadd memorizer; sudo usermod -aG memorizer <user>
|
|
You will be queried to enter your pw in order to set group
|
|
permissions on the /sys/kernel/debug dirs which include ftrace
|
|
and memorizer.
|
|
|
|
test_memorizer.py: accepts either -e, -m, or -h flags.
|
|
Ex: python test_memorizer.py -e
|
|
*All modes will run the setup/cleanup checks to ensure all virtual nodes
|
|
are being set correctly.
|
|
-e: Runs ls, wget, and tar sequentially.
|
|
-m: Runs the linux test suite and saves a human-readable log to
|
|
/opt/ltp/results/ltp.log
|
|
-h: runs both -e and -m
|
|
As with the memorizer.py, you will need your user to be in the
|
|
memorizer group. Additionally, you will be queried to enter your
|
|
pw in order to set group permissions on the /opt/ltp dirs.
