irqbalance dynamically switches the CPUs for IRQs to prevent cpu0 from

The Cpuset System is a processor and memory placement mechanism that
enables a system administrator to confine tasks to running certain

The Linux kernel's IEEE 1394 subsystem provides access to the raw 1394
bus through the raw1394 module. This includes the standard 1394
transactions (read, write, lock) on the active side, isochronous
stream receiving and sending and dumps of data written to the
FCP_COMMAND and FCP_RESPONSE registers. raw1394 uses a character
device to communicate to user programs using a special protocol.
libraw1394 was created with the intent to hide that protocol from
applications so that
- the protocol has to be implemented correctly only once.
- all work can be done using easy to understand functions instead of
handling a complicated command structure.
- only libraw1394 has to be changed when raw1394's interface changes.

mcelog retrieves machine check events from an x86-64 kernel in a cron
job, decodes them, and logs them to /var/log/mcelog.
A machine check event is a hardware error detected by the CPU.
It should run on any x86-64 system.
In addition, it allows decoding machine check kernel panic messages.
This utility allows updating the microcode of Intel and AMD x86 and x86-64
CPUs.
Tool to read and write MSRs (model specific registers). You have to
load the "msr" module manually ("modprobe msr").
Control NUMA policy for individual processes. Offer libnuma for
individual NUMA policy in applications.
Unlike other 'cpuinfo' tools which just parse /proc/cpuinfo, x86info
probes the CPU registers to find out more information. It can discover
the contents of model-specific registers, discover CPU silicon
revisions, and more.
The included tools share the same code as it is used in the ACPI
implementation of the kernel. The code of the acpica project is exactly
the same as the ACPI parser and interpreter code of the kernel and the
code gets synced regularly from the acpica project into the kernel.
E.g. if you identify bugs in the kernel's ACPI implementation it might
be easier to debug them in userspace if possible. If the bug is part of
the acpica code, it has to be submitted to the acpica project to get
merged into the mainline kernel sources.
iasl compiles ASL (ACPI Source Language) into AML (ACPI Machine
Language). This AML is suitable for inclusion as a DSDT in system
firmware. It also can disassemble AML, for debugging purposes.
This tool is to make access to the Linux kernel's processor power subsystems
like CPU frequency switching (cpufreq) or CPU sleep states (cpuidle) for users
and userspace tools easier.
Firescope allows to read remote kernel memory over a firewire
connection. On x86-64 it is normally used to read the kernel log
buffer.
This tool, developed by Intel, is meant for vendors to validate and
certifcate their BIOS. It is also convenient for ACPI or general BIOS
related bugs. If you have an ACPI error/warning, run this tool and
provide output for bug tracking information
