From 36664bd1742e7a463222014761d07eea7e19261b Mon Sep 17 00:00:00 2001

Subject: [PATCH 4566/4736] drm/amdgpu: initialize vm_inv_eng0_sem for gfxhub
and mmhub
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
SW must acquire/release one of the vm_invalidate_eng*_sem around the
invalidation req/ack. Through this way,it can avoid losing invalidate
acknowledge state across power-gating off cycle.
To use vm_invalidate_eng*_sem, it needs to initialize
vm_invalidate_eng*_sem firstly.
