[PATCH 6.12 163/232] drm/amdgpu: VCN v5_0_1 to prevent FW checking RB during DPG pause

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

6.12-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Sonny Jiang <sonny.jiang@amd.com>

[ Upstream commit 46e15197b513e60786a44107759d6ca293d6288c ]

Add a protection to ensure programming are all complete prior VCPU
starting. This is a WA for an unintended VCPU running.
