Find legacy BIOS E820 memory mapping information via int 0x15

stress-ng

This is the stress-ng upstream project git repository. stress-ng will stress test a computer system in various selectable ways. It was designed to exercise various physical subsystems of a computer as well as the various operating system kernel interfaces.

christmas-obfuscated-C

Obuscated C Christmas programs

powerstat

Powerstat measures the power consumption of a machine using the battery stats or the Intel RAPL interface. The output is like vmstat but also shows power consumption statistics. At the end of a run, powerstat will calculate the average, standard deviation and min/max of the gathered data.

forkstat

Forkstat is a program that logs process fork(), exec() and exit() activity. It is useful for monitoring system behaviour and to track down rogue processes that are spawning off processes and potentially abusing the system.

pagemon

Pagemon is an interactive memory/page monitoring tool allowing one to browse the memory map of an active running process.

fwts

The tool fwts comprises of over fifty tests that are designed to exercise and test different aspects of a machine's firmware.

faultstat

page fault tracking tool

smemstat

Smemstat reports the physical memory usage taking into consideration shared memory. The tool can either report a current snapshot of memory usage or periodically dump out any changes in memory.

cpustat

cpustat periodically dumps out the current CPU utilisation statistics of running processes. cpustat has been optimised to have a minimal CPU overhead and typically uses about 35% of the CPU compared to top. cpustat also includes some simple statistical analysis options that can help characterise the way CPUs are being loaded.

kernelscan

kernel scanning parser

linux-next

clone of https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next

health-check

The health-check tool monitors processes in various ways to help identify areas where it is consuming too many resources. One can trace one or more processes (including all their threads and child processes too) for a full story of system activity.

power-calibrate

Power-calibrate calibrates the power consumption of a mobile device that has a battery power source. It will attempt to calculate the power usage of 1% of CPU utiltisation.

debug-code

cmos-dump

cmos dumping tool

suspend-blocker

The suspend-blocker tool parses the kernel log and will explain the reasons that suspend was woken up or which wakelocks blocked suspend from working.

x86rdrand-benchmark

x86 rdrand benchmarking tool

pagein

tool to force pages in

eventstat

Eventstat periodically dumps out the current kernel event state. It keeps track of current events and outputs the change in events on each output update. The tool requires sudo to run since it needs to write to /proc/timer_stats to start and stop the event monitoring.

scripts

various scripts for debugging

fiemap

Reads file extents using the FIEMAP ioctl

idlestat

clone of Linaro idlestat + fixes

autotest-client-tests

tiny-smart

A tiny minimal example of how to read SMART data log values

eatpages

Program to consume pages to force low memory kernel and application failures

tpm2-scripts

Linux TPM driver TPM 2.0 test scripts. The master branch can be rebased at any time. If I ever decide to freeze this, I will create a merge-only next branch that will also provide baseline for the master.

x86latency-test

x86 cyclic latency sleep test

rseq

arch portable rseq test in C (with minimal assembler)

man-pages

clone of http://git.kernel.org/pub/scm/docs/man-pages/man-pages

pkg-spl-ubuntu

pkg-spl (ubuntu clone from kernel.ubuntu.com)

cppcheck-auto

cppcheck auto build and diff script

syzkaller-script

wrapper to autobuild and test kernels with syzkaller

fnotifystat

Fnotifystat is a program that dumps the file system activity in a given period of time.
