ACPIFAN(4) BSD Kernel Interfaces Manual ACPIFAN(4)NAME
acpifan -- ACPI Fan
acpifan* at acpi?
The acpifan device driver supports fans possibly exposed by the BIOS. Even if a system contains only one physical fan, multiple acpifan
instances may be present. In such cases each acpifan typically represents an acpitz(4) thermal zone, and the combined state of all instances
reveals the speed of the fan.
The acpifan driver does not support controlling the fan. The current state (on or off) is made available through the envsys(4) API and the

The acpifan device driver appeared in NetBSD 6.0.

The acpifan driver does not yet support additional functionality introduced in the ACPI 4.0 specification.

acpiwmi -- Windows Management Instrumentation support for ACPI
acpiwmi* at acpi?
acpiwmibus* at acpiwmi?
wmidell* at acpiwmibus?
wmieeepc* at acpiwmibus?
wmihp* at acpiwmibus?
wmimsi* at acpiwmibus?
The acpiwmi device driver provides an ACPI interface for Windows Management Instrumentation (WMI). The ACPI WMI interface is typically used
to support vendor specific features found in various laptops.
The following WMI mappings are supported:
wmidell Dell laptops
wmieeepc Some models of Asus Eee PC
wmihp Hewlett-Packard laptops
wmimsi MSI laptops
The functionality varies from vendor to vendor. Typically the interface is used for function and hotkey handling, but additional features
may be present.

The acpiwmi device driver appeared in NetBSD 6.0.
Jukka Ruohonen <email@example.com> wrote acpiwmi and most of the mappings.
While WMI should provide a certain degree of portability across laptop models from a particular vendor, there is no guarantee that the map-
pings are functional in all models.
The wmihp driver may conflict with hpqlb(4).

I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
