Erratum
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.

Erratum
Certain devices are known to have incompatibilities with the test
causing a system hang during testing. This erratum is for those
devices The PCIHCT tests Bit 15 of the Device Control Register in the
PCI Express Capability table. The testing of Bit 15, specifically the
writing of a 1 to the bit causes a function level reset making the
device unavailable for a maximum of 100ms. All writes to the PCI
config space of the device are ignored during the reset. All reads to
the PCI config space of the device return all ones (1). This confuses
the PCIHCT test and it incorrectly fails the assertions for Bits 4, 11,
12, 13 and 14. Assertion 73C19B53-84B8-4BA4-97EA-
3FF6DEF57273: FAILED. Bit 4 (Enable Relaxed Ordering) in the Device
Control register (offset 8h) in the PCI Express Capability table must be
read-writable if it's implemented. Assertion C0846E74-2CFE-4CC2-
A492-6AAF16F206CD: FAILED. Bit 11 (Enable No Snoop) in the Device
Control register (offset 8h) in the PCI Express Capability table must be
read-writable if it's implemented. Assertion A56B0EE0-0C2C-47A4-
90C4-5F8EEB30D427: FAILED. Bit range 14:12
(Max_Read_Request_Size)in the Device Control register (offset 8h) in
the PCI Express Capability table must be read-writable if implemented.
Assertion 13A41D3E-2576-41DC-A67C-525DA3637CEA: FAILED. 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

Erratum
The Bit 5 (Surprise Down Error Severity) in the Uncorrectable Error
Severity register (offset Ch) in the Advanced Error Reporting
Capability table must be read-only and always return 1 if the Bit 5
(Surprise Down Error Mask) in the Uncorrectable Error Mask Register
in the Advanced Errror Reporting Capability table is not implemented

UAA Test - Vista

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.

UAA Test - Vista

Erratum
Certain HD Audio codecs allow setting unsupported VRef settings in
the pin control register. They have hardware validation that prevents
the unsupported VRef settings from affecting the actual voltage, but
subsequent reads from the pin control register will return values that
are out of sync with what the actual voltage is. This requires a
hardware fix so the failure is forgiven for these specific codecs.
Future designs must advertise the VRefs correctly. The failing test log
is UAATest.wtl.
