VMCTL(8) - System Manager’s Manual # VMCTL(8) - System Manager’s Manual
NAME # vmctl - control the virtual machine daemon
SYNOPSIS # vmctl [-v] command [arg …]
DESCRIPTION # The vmctl utility is used to control the virtual machine monitor (VMM) subsystem. A VMM manages virtual machines (VMs) on a host. The VMM subsystem is responsible for creating, destroying, and executing VMs.
The -v option enables verbose mode. Within the commands, the size argument can be specified with a human-readable scale, using the format described in scan_scaled(3).

VMT(4) - Device Drivers Manual # VMT(4) - Device Drivers Manual
NAME # vmt - VMware Tools driver
SYNOPSIS # vmt0 at pvbus0
DESCRIPTION # The vmt driver is a kernel level implementation of VMware Tools. VMware Tools are intended to provide better support for operating systems running inside virtual machines.
vmt handles shutdown and reboot requests from the host by signalling init(8) with SIGUSR2 and SIGINT respectively. vmt will log notifications that the guest has been suspended or resumed by the host.

WATCHDOG(4) - Device Drivers Manual # WATCHDOG(4) - Device Drivers Manual
NAME # watchdog - hardware timers/counters for quick crash recovery
DESCRIPTION # Hardware watchdog timers are devices that reboot the machine when it hangs. The kernel continually resets the watchdog clock on a regular basis. Thus, if the kernel halts, the clock will time out and reset the machine. Watchdog timers may be configured to be reset from userland to cause a reboot if process scheduling fails; see watchdogd(8) for further information.

WATCHDOGD(8) - System Manager’s Manual # WATCHDOGD(8) - System Manager’s Manual
NAME # watchdogd - watchdog timer retrigger daemon
SYNOPSIS # watchdogd [-dnq] [-i interval] [-p period]
DESCRIPTION # watchdogd is a daemon to activate and periodically retrigger the watchdog(4) timer device from userland. watchdogd is designed to work in high load environments, where other methods (such as a shell script invoking sysctl(8)) would involve too much overhead.
The basic premise is that after every interval seconds, watchdogd resets the hardware timer to period.

NAME # wbenv - Winbond W83L784R/W83L785R/W83L785TS-L temperature, voltage, and fan sensor
SYNOPSIS # wbenv* at iic?
DESCRIPTION # The wbenv driver provides support for the Winbond W83L784R, W83L785R and W83L785TS-L hardware monitors to be used with the sysctl(8) interface.
The W83L874R and W83L785R possess several voltage, temperature and fan speed sensors. The W83L785TS-L only has a single temperature sensor.

NAME # wbng - Winbond W83793G temperature, voltage, and fan sensor
SYNOPSIS # wbng* at iic?
DESCRIPTION # The wbng driver provides support for the Winbond W83793G Hardware Monitor. The device provides 10 voltage sensors, 6 temperature sensors and 12 fan sensors. Sensor values are made available through the sysctl(8) interface.

WITNESS(4) - Device Drivers Manual # WITNESS(4) - Device Drivers Manual
NAME # witness - lock validation facility
DESCRIPTION # The witness module keeps track of the locks acquired and released by each thread. It also keeps track of the order in which locks are acquired with respect to each other. Each time a lock is acquired, witness uses these two lists to verify that a lock is not being acquired in the wrong order.
