If anyone has any objections, please let me know. ------------------ From: Lijo Lazar [ Upstream commit c235a7132258ac30bd43d228222986022d21f5de ] There are a few prechecks made before HDP flush like a flush is not required on APU bare metal. Using hdp callback directly bypasses those checks. Use amdgpu_device_flush_hdp which takes care of prechecks.
