Win7: PCI Hardware
Compliance Test For
Systems
12/01/2012
401
Erratum
Issue Description:
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 reserved 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.

Issue Description:
Data Link Layer Link Active Reporting Capable bit is
set but Data Link Layer Link Active is not.

Issue Description:
Bit range 15:0 (Extended Capability ID)in the
Enhanced Capability Header register (offset 0h) in
the Unrecognized Enhanced Capability ID 13 table
is Dh. It must be in the range [0x0 - 0xB] as all
other Capability IDs are reserved.

Erratum
Issue Description:
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.

Issue Description:
Run AC3 test on a system with the Microsoft HD
Audio class driver installed. Expected results: All
AC3 kernel streaming data ranges should advertise
MinimumBitsPerSample = 16 and
MaximumBitsPerSample = 16. Actual results: HD
Audio class driver sometimes advertises
MaximumBitsPerSample = 24.

Erratum
Issue Description:
The European Union requires the headphone
output level to be <= 150 mVrms for headphone
jacks. There's a note in WLP requirement AUDIO-
0006 that states, in the presence of regional
regulations, the output level requirement for
headphones is dropped from >= 1000 mVrms
to >= 120 mVrms. This provides freedom for
manufacturers to meet both the EU <= 150 mVrms
@ 32 Ohms and the WLP >= 120 mVrms @ 32
Ohms requirements. The Fidelity Test tests
headphones at 300 Ohm load, though. Without
knowledge of the output impedance at the jack,
the test cannot extrapolate what the output level
at 32 Ohms would have been from the output level
at 300 Ohms. The test assumes that the output
level at 32 Ohms will be *less* than the output
level at 300 Ohms, though. So any
