Detected Parity Error (DPE) bit in the
PCISTS or SECSTS register set appro-
priately.
Non-advisory cases: uncorrectable
error processing.
Advisory cases: correctable error pro-
cessing.
TLP header logged in AER for advisory
and non-advisory cases. Else, TLP
header is not logged.
Affected packet is forwarded across the
bridge function (unless the bridge func-
tion is the ultimate receiver of the TLP,
in which case the TLP is dropped by
this function).
Non-advisory cases: uncorrectable
error processing.
Advisory cases: correctable error pro-
cessing.
TLP header logged in AER.
Affected packet is forwarded across the
bridge (unless the bridge function is the
ultimate receiver of the TLP, in which
case the TLP is dropped by this func-
tion).
Non-advisory cases: uncorrectable
error processing.
Advisory cases: correctable error pro-
cessing.
TLP header logged in AER.
For Non-Posted unsupported requests,
the function that claims the TLP gener-
ates a completion with UR status. If the
request is not claimed, then function 0
generates the completion with UR sta-
tus.
Not applicable (the bridge never issues
requests).
Not applicable. Switch ports never
issue completions with 'Completer
Abort' status except for ACS violations.
For the latter, the error is considered an
ACS error and is not logged as a com-
pleter abort error.
