Hello @quic-pansing,

Yes the changes has been verified at our end on couple of systems. Can you please share the exception logs to determine which register access has cause this issue. Also are you run the ACS on top of baremetal system or edk2 based system.

Thanks, ACS team

thanks @chetan-rathore This is EDK2 based system. I believe this mrs x0, erridr_el1 this is creating "unhandled synchronous exception"

chetan-rathore commented 1 month ago

thanks @quic-pansing for the information. We will analyze more on this register access.

Hello Pankaj,

Access to this register is permitted only if FEAT_RAS is implemented. The ACS attempts to access the register solely when FEAT_RAS is present.

Additionally, access to Error Record registers from lower exception levels (such as EL2) requires Disabling the SCR_EL3.TERR bit to not trap the access. Please confirm that the relevant configuration is enabled.

Regards, ACS Team
