FB-DIMM RAS Registers
There are two sets of the following registers, one set for each FB-DIMM branch. They
each appear in function 0 of different devices as shown in
UERRCNT[1:0] - Uncorrectable Error Count
This register implements the “leaky-bucket” counters for uncorrectable errors for each
rank. Each field “limits” at a value of “15” (“1111”). Non-zero counts are decremented
when the ERRPER threshold is reached by the error period counter. Counts are frozen at
the threshold defined by SPCPC.SETH and set the SPCPS.LBTHR bit. Writing a value of
“1111” clears and thaws the count. Changing SPCPC.SETH has no effect upon a frozen
count.
Aliased uncorrectable errors are NOT counted as uncorrectable errors in the
implementation of this register. They are treated as correctable errors and logged in
the CERRCNT register.
