Max Read Request Size (MRRS) — RO. Hardwired to 0.
Enable No Snoop (ENS) — RO. Not supported. The root port will never issue non-
snoop requests.
Aux Power PM Enable (APME) — R/W. The OS will set this bit to 1 if the device
connected has detected aux power. It has no effect on the root port otherwise.
Phantom Functions Enable (PFE) — RO. Not supported.
Extended Tag Field Enable (ETFE) — RO. Not supported.
Max Payload Size (MPS) — R/W. The root port only supports 128-B payloads,
regardless of the programming of this field.
Enable Relaxed Ordering (ERO) — RO. Not supported.
Unsupported Request Reporting Enable (URE) — R/W.
0 = Disable. The root port will ignore unsupported request errors.
1 = Enable. Allows signaling ERR_NONFATAL, ERR_FATAL, or ERR_COR to the Root
Fatal Error Reporting Enable (FEE) — R/W.
0 = Disable. The root port will ignore fatal errors.
1 = Enables signaling of ERR_FATAL to the Root Control register due to internally
Non-Fatal Error Reporting Enable (NFE) — R/W.
0 = Disable. The root port will ignore non-fatal errors.
1 = Enables signaling of ERR_NONFATAL to the Root Control register due to internally
Correctable Error Reporting Enable (CEE) — R/W.
0 = Disable. The root port will ignore correctable errors.
1 = Enables signaling of ERR_CORR to the Root Control register due to internally
Control register when detecting an unmasked Unsupported Request (UR). An
ERR_COR is signaled when a unmasked Advisory Non-Fatal UR is received. An
ERR_FATAL, ERR_or NONFATAL, is sent to the Root Control Register when an
uncorrectable non-Advisory UR is received with the severity set by the
Uncorrectable Error Severity register.
