Erratum
The original HD Audio 1.0 specification contains a notion of
"presence detect", using electrical impedance which was
intended to apply only to analog pins. However, the language of
the specification was such that it could be read to apply to
digital pins as well - in particular, to S/PDIF pins. A DCN was
released to extend the notion of presence detect to digital pins
- in particular, to HDMI pins. This repurposed one of the
impedance bits, which were thought to be unused in digital pins,
to mean "ELD valid." The correct way for a S/PDIF pin to
respond to a Pin Sense verb is to set the highest bit (Presence
Detect) to 1 or 0 corresponding to whether a S/PDIF connection
is active; set the ELD Valid bit to 0 (since there is no such thing
as ELD for S/PDIF); and set the rest of the bits, which are
reserved for digital pins, to 0. This errata filter is a preview filter
to allow hardware manufacturers time to update any hardware
that used the impedance bits on digital pins.

HD Audio pin configuration document calls out setting Port
Connectivity to No Connection as the way to turn a pin off in a
particular system. UAA Test incorrectly tests such pins.

Erratum
UAA Test requires the Traffic Priority bit to be read/write -
however there are two specs that apply, and they conflict. One
says the bit must be read/write, the other says it must be read-
only. Contact has been made with the author of both specs
(Intel) but until this point is clarified we cannot fail submissions
containing this test failure.

Erratum
This happens because the PCI Compliance test assumes that if
the Data Link Layer Link Active Reporting Capable bit in the Link
Capabilities register for a given PCIe port is set then that
indicates that the Data Link Layer Link Active bit will also be set.
This is an incorrect assumption because the Data Link Link
Layer Link Active bit can be reset when there is no device
below the port. This assertion needs to be removed from the
PCIHCT. The current architecture of the PCIHCT prevents it from
knowing whether devices exist below a bridge/port.
