Docking Supported (DS) — R/WO. A 1 indicates that ICH8 supports HD Audio Docking.
The DCKCTL.DA bit is only writable when this DS bit is 1. ACPI BIOS software should
only branch to the docking routine when this DS bit is 1. BIOS may clear this bit to 0 to
prohibit the ACPI BIOS software from attempting to run the docking routines.
Note that this bit is reset to its default value only on a PLTRST#, but not on a CRST# or
D3hot-to-D0 transition.
Reserved.
Dock Mated (DM) — RO. This bit effectively communicates to software that an Intel
HD Audio docked codec is physically and electrically attached.
Controller hardware sets this bit to 1 after the docking sequence triggered by writing a
1 to the Dock Attach (GCTL.DA) bit is completed (HDA_DOCK_RST# deassertion). This
bit indicates to software that the docked codec(s) may be discovered via the STATESTS
register and then enumerated.
Controller hardware sets this bit to 0 after the undocking sequence triggered by writing
a 0 to the Dock Attach (GCTL.DA) bit is completed (HDA_DOCK_EN# deasserted). This
bit indicates to software that the docked codec(s) may be physically undocked.
Next Capability (Next) — RO. Hardwired to 60h. Points to the next capability structure
(MSI)
Cap ID (CAP) — RO. Hardwired to 01h. Indicates that this pointer is a PCI power
management capability.
