Logged Errors
For the hub interface, the logged errors are:
• Outbound Write/Read ECC Error on Header: Corrupted Header.
• Outbound Write ECC Error on Data: Good Header and Corrupted Data.
• Inbound Read Completion Error on Completion Header: Corrupted Completion Header.
• Inbound Read Completion Error on Completion Data: Good Request (not completion) Header
and Corrupted Data.
For PCI, the logged errors are:
• Outbound Write/Read Parity Error on Address/Attributes: Corrupted Address/Attributes.
• Outbound Write Parity Error on Data: Good Address and Corrupted Data.
• Inbound Read Completion Error on Completion Address/Attributes: Corrupted Completion
Address/Attributes.
• Inbound Read Completion Error on Completion Data: Good Request (not completion)
Address/Attributes and Corrupted Data.
Allowable Error Combinations for RAS_STS
One PCI error (fatal or non-fatal), and one hub interface error (fatal or non-fatal) may occur at the
same time. For example, two cycles could target the P64H2 from different interfaces (one from the
hub interface and one from PCI, and both have errors detected on the same clock. Due to this,
there may be two bits set in the RAS_STS Register. They are:
• One of HTA, HMA, AEHS, DEHS, AEHM, DEHM, DEBO
• One of PTA, PRMA, AEP, DEP, DEBI
