From 0f04e538580c086046e3b31cbc7ef4307a5b771d Mon Sep 17 00:00:00 2001 From: Felix Kuehling Date: Thu, 3 May 2018 17:37:56 -0400 Subject: [PATCH] drm/amdgpu: Fix KFD doorbell SG BO mapping This change prepares for adding SG BOs that will be used for mapping doorbells into GPUVM address space. This type of BO would be mistaken for an invalid userptr BO. Improve that check to test that it's actually a userptr BO so that SG BOs that are still in the CPU domain can be validated and mapped correctly.
