Assertion CF68482E-9EEF-45B4-A8B8-1379AB6CF94A
Bit range 9:4 (Negotiated Link Width) in the Link Status register (offset 12h)
in the PCI Express Capability table is 0h. It must be in the set of values {0x1,
0x2, 0x4, 0x8, 0xc, 0x10, 0x20}.
Additional information

multiple system configuration)

PCI Hardware Compliance Test
According to the PCI Express Base Specification, Rev 2.0 Section 7.8.8, this
bit field is undefined when the link is not up. If there is not PCIe device
behind the bridge, then the link can NOT be up and therefore the field is
undefined. Bit 13 in the same register (Link Status) can be used to determine
if the link is active (up). The PCIHCT uses the Presence Detect State bit of
the Slot Status register to determine whether a child device is present.
However, the Presence Detect State bit only returns valid data if the Slot
Implemented bit is set (bit 8 of PCIe capabilities register). If the PCIe root
port or downstream port will never have a device behind it, the Slot
Implemented bit is cleared to 0. Per the spec, PDS will always be 1 when the
Slot Implemented bit is clear. Therefore PDS cannot be used to determine
device presence when the SI bit is clear.
