If fencing fails, the function that validates the buffer must clean the unfenced list. There is a function to clean the unfenced list in drm_bo.c.
This is typically called if the function receives a signal while waiting to validate a buffer, which is a very common case if the X server is the caller. If command submission has already occured when fencing fails, the calling function must wait for GPU idle before cleaning the list. /Thomas >------------------------------------------------------------------------- >This SF.net email is sponsored by: Microsoft >Defy all challenges.
