AMDMSR(4) - Device Drivers Manual (i386) # AMDMSR(4) - Device Drivers Manual (i386)
NAME # amdmsr - access MSRs on certain AMD Geode LX systems
SYNOPSIS # amdmsr0 at mainbus?
DESCRIPTION # The amdmsr device provides access to the Model Specific Registers (MSRs) on systems with an AMD Geode LX CPU and graphics processor.
IOCTL INTERFACE # MSRs can be read or written via ioctl() calls performed on /dev/amdmsr. Declarations and data types are to be found in <machine/amdmsr.

ARCOFI(4) - Device Drivers Manual # ARCOFI(4) - Device Drivers Manual
NAME # arcofi - Siemens PSB2160 audio codec
SYNOPSIS # arcofi* at gsc? audio* at arcofi?
DESCRIPTION # The arcofi driver supports the HP “Audio1” audio devices, based upon the Siemens PSB2160 “ARCOFI” codec, to implement the audio device interface described in audio(4).
This device is found onboard HP 9000 workstations models 425e, 705 and 710.
The arcofi is limited to a mono, 8000 KHz sound, either with 8-bit phone-quality mu-law or a-law samples, or 16-bit signed linear samples in big-endian byte order.

NAME # audio, audioctl - device-independent audio driver layer
SYNOPSIS # audio* at …
#include <sys/types.h>
#include <sys/ioctl.h>
#include <sys/audioio.h>
#include <string.h>
DESCRIPTION # The audio driver provides support for various audio peripherals. It provides a uniform programming interface layer above different underlying audio hardware drivers.
In addition to hardware mixer controls like those documented in azalia(4), the audio driver exposes the record.

AUDIOCE(4) - Device Drivers Manual (sparc64) # AUDIOCE(4) - Device Drivers Manual (sparc64)
NAME # audioce - SPARC64 EBus CS4231 audio device
SYNOPSIS # audioce* at ebus? audio* at audioce?
DESCRIPTION # The audioce device uses the Crystal Semiconductor CS4231A Parallel Interface, Multimedia Audio Codec chip to implement the audio device interface described in audio(4). This device is found onboard on some PCI/EBus based sparc64 models.
The audioce has a maximum precision of 16 bits and has both stereo and monoaural outputs.

BIO(4) - Device Drivers Manual # BIO(4) - Device Drivers Manual
NAME # bio - block I/O ioctl tunnel pseudo-device
SYNOPSIS # pseudo-device bio [count]
DESCRIPTION # The bio driver provides userland applications ioctl(2) access to devices otherwise not found as /dev nodes. The /dev/bio device node operates by delegating ioctl calls to a requested device driver. Only drivers which have registered with the bio device can be accessed via this interface.

BPF(4) - Device Drivers Manual # BPF(4) - Device Drivers Manual
NAME # bpf - Berkeley Packet Filter
SYNOPSIS # pseudo-device bpfilter
DESCRIPTION # The Berkeley Packet Filter provides a raw interface to data link layers in a protocol-independent fashion. All packets on the network, even those destined for other hosts, are accessible through this mechanism.
The packet filter appears as a character special device, /dev/bpf. After opening the device, the file descriptor must be bound to a specific network interface with the BIOCSETIF ioctl(2).

#include <net/if.h>
#include <netinet/in.h>
#include <netinet/if_ether.h>
#include <net/if_bridge.h>
DESCRIPTION # The bridge device creates a logical link between two or more Ethernet interfaces or encapsulation interfaces (see [etherip(4)](/man/man4/etherip.4)). This link between the interfaces selectively forwards frames from each interface on the bridge to every other interface on the bridge.
