AcpiTool is a Linux ACPI client. It's a small command line application, intended to be a replacement for the apm tool. The primary target audience are laptop users, since these people are most interested in things like battery status, thermal status and the ability to suspend (sleep mode). The program simply accesses the /proc/acpi or /sysfs entries to get or set ACPI values. A computer running a Linux kernel from the 2.4.x or 2.6.x series with ACPI enabled is needed. It also supports various extensions for Toshiba, Asus, and IBM Thinkpad laptops.

Changes: This release fixes the output for Bogomips and C-state usage for everything that looks like an SMP system (Intel Core Duo, Pentium 4 with HyperThreading, AMD Opteron, etc.).


Changes: This release fixes the output of Bogomips (again) for AMD-64 CPUs (at least the 3500+). Cache size information has been added. A bug causing acpitool to enter an infinite loop when trying to display c- state usage for AMD-64 3500+ CPUs has been fixed.
