ras_controller_interrupt and SDP err_event_athub_interrupt are two dedicated interrupt for VG20 RAS controller
ras_controller interrupt will be triggered when there is NBIF error. Driver can leverage this interrupt to query and log necessary error count and other information. err_event_athub interrupt will be triggered when sdp err_event received from ATHUB. This is an very important ras interrupt for all hw block (except BIF and SDMA) when uncorrectable error happens and hw probably freeze. Driver can leverage this interrupt to query and log necessary error count before reset GPU. BIF ring was designed and dedicated for both interrupts. However, it can't be enabled due to known HW bug. Driver has to poll BIF_DOORBELL_INT_CNTL register to check whether the interrupt is triggered or not.
