GLXSB(4) - Device Drivers Manual (i386) # GLXSB(4) - Device Drivers Manual (i386)
NAME # glxsb - Geode LX Security Block crypto accelerator
SYNOPSIS # glxsb* at pci?
DESCRIPTION # The glxsb driver supports the security block of the Geode LX series processors. The Geode LX is a member of the AMD Geode family of integrated x86 system chips.
Driven by periodic checks for available data from the generator, glxsb supplies entropy to the random(4) driver for common usage.

GPIOCHARGER(4) - Device Drivers Manual # GPIOCHARGER(4) - Device Drivers Manual
NAME # gpiocharger - GPIO battery charger
SYNOPSIS # gpiocharger* at fdt?
DESCRIPTION # The gpiocharger driver provides support for battery chargers connected to GPIO pins. Currently, only power supply status events are supported.
The power supply status (connected or disconnected) is set up as a sensor and can be monitored using sysctl(8) or sensorsd(8).

GPIODCF(4) - Device Drivers Manual # GPIODCF(4) - Device Drivers Manual
NAME # gpiodcf - DCF77 timedelta sensor through GPIO pin
SYNOPSIS # gpiodcf* at gpio? offset 0 mask 0x1 gpiodcf* at gpio?
DESCRIPTION # The gpiodcf driver decodes the DCF77 time signal code using one GPIO pin. The pin is used as a data signal. The GPIO pin must be able to read an input.
The pin number can be specified in the kernel configuration with the offset locator.

NAME # gpioleds - GPIO LEDs
SYNOPSIS # gpioleds* at fdt?
DESCRIPTION # The gpioleds driver provides support for LEDs connected to GPIO pins.
Currently, LEDs are only set to their default state, e.g. to indicate the power status of the system.
SEE ALSO # gpio(4), intro(4)
HISTORY # The gpioleds driver first appeared in OpenBSD 7.1.
AUTHORS # The gpioleds driver was written by Klemens Nanni <kn@openbsd.
