Class Driver AC3 Test - Win7
(System)
6/1/2010 1256
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.

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.
PCI Hardware Compliance
Test For Systems
2/8/2010 401
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.
UAA Test - Win7 (System)
6/1/2010 513
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.

TPM TCG OS Interface Test
6/1/2015 1775
Erratum
Errata 1775 The Physical Presence Lifetime
Lock on the TPM 1.2 device was not set
during the manufacturing process. Once set,
the lifetime lock is permanent, so
occasionally platform manufacturers wait
until late in platform development to set the
value. To pass the TCG TPM Integration
Test, the value must be set.
