DDC(4)							   BSD Kernel Interfaces Manual 						    DDC(4)

ddc -- VESA Display Data Channel V2 devices SYNOPSIS
ddc at iic? addr 0x50 DESCRIPTION
The ddc driver provides support for accessing the VESA Display Data Channel Version 2 supported by many video displays. BUGS
This driver does not provide any mechanism for access from user applications. Its only use at this point is to provide a means for frame- buffer device drivers to query monitor description data (EDID) using a specialized in-kernel API. No support for sending control commands to display devices is provided. SEE ALSO
iic(4), ddc(9), edid(9) HISTORY
The ddc device appeared in NetBSD 4.0. AUTHORS

acpismbus -- ACPI SMBus Control Method Interface SYNOPSIS
acpismbus* at acpi? iic* at acpismbus? DESCRIPTION
The acpismbus driver supports instances of the ACPI SMBus Control Method Interface. This enables i2c access to bus segments which might not otherwise be accessible due to missing "native" driver support. The SMBus Process Call protocol is not supported. All other SMBus protocols are supported to the extent that the underlying controller supports them. SEE ALSO
acpi(4), iic(4) HISTORY
The acpismbus driver appeared in NetBSD 6.0. BUGS
Although acpismbus SMBus Alerts can be associated with individual devices, this capability is ignored. When an acpismbus SMBus Alert is gen- erated, all devices on the i2c bus segment which have registered an interrupt routine are notified. The SMBus CMI protocol defines a method to provide a list of devices on an i2c bus segment and their addresses. The acpismbus driver makes no attempt to retrieve or process this device list. There is currently no way to determine if the i2c controller managed by an instance of the ACPI SMBus CMI can also be accessed using a native device driver. Therefore, the acpismbus driver should not be enabled by default. If both a native driver and the acpismbus driver attempt to access the same i2c bus segment, the results are undefined. BSD
