1.
Data Link Layer Link Active Reporting Capable bit is set but
Data Link Layer Link Active is not.
2.
The following PCI Compliance test failure is acceptable: Bit 15
(Bridge Configuration Retry Enable) in the Device Control
register (offset 8h) in the PCI Express Capability table must
be read-only and always return 0 as it is rese
rved for devices
other than PCI Express to PCI/PCI-X Bridges. Assertion
13A41D3E-2576-41DC-A67C-525DA3637CEA This failure is
acceptable because this is a PCIe 1.1 feature and the WLP
requires compliance with only PCIe 1.0a.

Filter
-
[Filter Number:1394 Row:561 ] - 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.

Class Driver Fidelity
Test

EU restrictions place a cap on the output level of headphone jacks
at 32 Ohm load: headphones are not allowed to have an electrical
output of more than 150 mV at that load.
We test headphone jacks at 300 Ohm load; the relationship
between the outpu
t at 32 Ohms and the output at 320 Ohms
depends on the output impedance of the headphone jack.
In particular, if a headphone jack meets the EU requirement of X <=
150 mV at 32 Ohms, depending on the output impedance, it could
output a huge amount of power
at 300 Ohms, or very slightly over
X mV. Since we require X >= 120 mV at 32 Ohms, absent
knowledge of the output impedance we can only require X >= 120
mV at 300 Ohms.
120 mV is
-18.42 dBV. Any headphone output level at 32 Ohms
that is less than
-18.42 dBV is a legitimate failure, even if it is
targeted at EU compliance. Any headphone output level greater
than 1 Vrms (0.707 Vrms for mobile systems) is a legitimate pass,
regardless of EU compliance.
This errata covers output level failures for headphone j
acks
between
-18.42 dBV and 1 Vrms/0 dBV (0.707 Vrms/-
6.93 dBV for
mobile systems)) in accordance with note 6 of the WLP fidelity
requirements.
