IERR

大纲/内容
check which CPU's BIT20 (Internal MSMI) is 1， this is the error socket
IERR detected
Read the MCERRLOGGINREG of that CPU
=1？
check the Bit8(FirstIerrSrcValid) and Bit 7-0 (FirstIerrSrcId)
Read the MCERRLOGGINREG of two CPUs
=1?
check the Bit8(FirstMCerrSrcValid) and Bit 7-0 (FirstMCerrSrcId)
Get the first error source
read MCA_ERR_SRC_LOG of two CPUs
No
If both are PCU， the PCU with no-strike time is the error source
The vaild FirstMCerrSrcId which is NOT \"PCU\" is the error source
Yes
check the CPU's BIT18 (MSMI_MCERR_Internal) is 1
BIT23(External MSMI) & BIT20(Internal MSMI)
Read the IERRLOGGINGREG of that CPU
