When Two Functions Have Differing MAX_PAYLOAD_SIZE, the
Device Might Use the Larger Value For All Functions.
Upstream Attempt to Reconfigure the PCIe Link By Moving the
Link Training Status State Machine (LTSSM) From Recovery to
Configuration Will Cause a “Link Down” Event.
When Using Serial Over LAN, the Device’s Power State Can Be
Ambiguous.
MAX_PAYLOAD_SIZE is programmed per function. If two PCIe functions have different
No Fix: There are no plans to fix this erratum.
The device will not move its LTSSM from Recovery to Configuration when it receives
Training Sequences (TS) with only “lane number” set to PAD.
Recovery.Idle state to the Configuration state (sending TS1s with only “lane number” set
to PAD), the link will fail and the units will go to Detect states, causing a “link down”
event.
No Fix: There are no plans to fix this erratum.
The same physical line is allocated for SMBus Alert and for S0 Power Indication. In Serial-
Over-LAN (SOL), both are needed by manageability firmware, which treats these
indications as separate. For LOMs containing SOL, the line is used for SMBus Alert.
No Fix: There are no plans to fix this erratum.
MAX_PAYLOAD_SIZE, the device might use the larger value for all functions. The usage
model for the device is to have all functions use the same MAX_PAYLOAD_SIZE.
•SOL behavior might be confused because an SMBus Alert might be considered as a
•SOL cannot ascertain when a power state change has occurred
Workaround: None.
