Kryo EDAC node is defined to describe on-chip error detection and correction
|
|
for the Kryo core.
|
|
|
|
Kryo will report all SBE and DBE found in L1/L2/L3/SCU caches in two registers:
|
|
ERRXSTATUS - Error Record Primary Status Register
|
|
ERRXMISC0 - Error Record Miscellaneous Register
|
|
|
|
Current implementation of Kryo ECC mechanism is based on interrupts.
|
|
The following section describes the DT node binding for kryo_cpu_erp.
