From b41ffc6180649d02c93de7bf15c81f44c2a56ee4 Mon Sep 17 00:00:00 2001

Subject: [PATCH 3973/4256] drm/amdkfd: Query vmid pasid mapping through stored
info for non HWS
Because we record the mapping under non HWS mode in the software,
we can query pasid through vmid using the stored mapping instead of
reading from ATC registers.
This also prepares for the defeatured ATC block in future ASICs.
