estd - Frequency Scaling Daemon for NetBSD and DragonFly

Description

This daemon dynamically sets the CPU-frequency on SpeedStep-, PowerNow-, and ACPI P-States enabled CPUs depending on current cpu-utilization. It supports NetBSD 3.0 or later and DragonFly BSD.

estd is written by Ove Soerensen with patches from Stephen M. Rumble and myself. 2009 I have taken over maintainership of the estd project.

Changes from r6 to r7

• Support for ACPI P-States on DragonFly.
• Better support for SMP systems on DragonFly:
  • Frequency for separate CPU domains is controlled individually.
  • For each domain the load on the most loaded CPU is used to decide whether to increase the frequency.
