[PATCH] drm/amdkfd: add edc error interrupt handle for poison propogate mode

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

In poison progogate mode, when driver receive the edc error interrupt
from SQ, driver should kill the process by pasid which is using the
poison data, and then trigger GPU reset.
