Memory Errors (Continued)
37 RCS 0 Unc
M3: Uncorrectable Memory ECC Error on Memory Scrub
The SNC has poisoned the Memory ECC codeword that contained
the error and written the data back to memory. See Section 5.2, “Error
Correction.”
36 RCS 0 Unc
M4: Partial Merge Multi-Bit Data ECC Error
A multi-bit error was detected when merging a partial memory write
with the rest of the line read from memory. The write must be less
than 8 bytes and the error must be in that 8-byte boundary. The error
may be in the initiator supplied data. The 32-byte Memory ECC
codeword that contains the error is poisoned when the data is written
to memory.
35 RV 0 Corr Reserved
34 RCS 0 Corr
M6: Single-Bit Memory ECC Error on Write
The SNC has corrected the error and generated valid chipset Memory
ECC for the data in memory.
33 RCS 0 Corr
M7: Correctable Memory ECC Error on Read or Memory Scrub
For memory reads, the SNC has returned corrected data with
SEC/DED ECC to the processor bus or SP.
For Scrubs, the SNC has corrected the error and generated valid
chipset Memory ECC for the data in memory.
32 RCS 0 Corr
M8: Partial Merge Single-Bit DATA ECC Error
A single-bit error was detected when merging a partial memory write
with the rest of the line read from memory. The write must be less
than 8 bytes and the error must be in that 8-byte boundary. The error
may be in the initiator supplied data or the read data. The SNC has
corrected the error and generated valid chipset Memory ECC for the
data in memory.
Scalability Port Physical Layer Errors

23 ROS 0 N/A
SPL Fatal Error Pointer
If an SPL has reported the first fatal error, this field indicates which
scalability port has reported the error.
0 = Scalability Port 0
1 = Scalability Port 1
22 ROS 0 N/A
SPL Uncorrectable Error Pointer
If an SPL has reported the first non-fatal error and the error is an
uncorrectable error, this field indicates which SP has reported the
error.
21 ROS 0 N/A
SPL Correctable Error Pointer
If an SPL has reported the first non-fatal error and the error is a
correctable error, this field indicates which SP has reported the error.
20 RCS 0 Fatal
S1: Link Error
A parity error was detected in an incoming flit and Link Level Retry
was disabled or the maximum number of retries was exceeded.
