Subject: drm/amdgpu: add TA_RAS_INV_NODE value
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=95024c714b83d267036564be998328762c47fbda;p=users%2Fjedix%2Flinux-maple.git

drm/amdgpu: add TA_RAS_INV_NODE value

We can set UMC node instance to invalid state if we use global channel
index, and RAS TA can choose UMC address conversion approach by checking
node_inst value.
