Dear Friends,
I am using TF-A to test RAS feature. When I triggered DMC620 RAS error in Linux(echo 0x123 > /sys/kernel/debug/sdei_ras_poison). BL32 will recieve UnRecognized Event - 0xC4000061(SP_EVENT_COMPLETE_AARCH64) and finally BL31 crashed.
In my understanding, this 0xC4000061 should consumed by BL31, not send it to BL32 again.
A piece of error log as below: ************************************* CperWrite - CperAddress@0xFF610064 CperWrite - 1 Section@FFBE91A8, Length 80, SectionType@FFBE9138 CperWrite - Got Error Section: Platform Memory.

My question is, 1. Does BL31 need to send 0xC4000061 event to BL32 again? 2. Does current TF-A support to run RAS test? It seems BL31 will crash.
Appreciate your help.
