Hi, it looks like amdgpu's userptrs are now broken:

https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_6179/fi-kbl-8809g/ igt@amdgpu_amd_basic@userptr.html

Starting subtest: userptr (amd_basic:3888) CRITICAL: Test assertion failure function amdgpu_userptr_test, file ../tests/amdgpu/amd_basic.c:1331: (amd_basic:3888) CRITICAL: Failed assertion: r == 0 (amd_basic:3888) CRITICAL: Last errno: 19, No such device (amd_basic:3888) CRITICAL: error: -19 != 0

Is quite clear for a change.

Now one might argue that amdgpu changing the userptr ABI behind a non-default config option from a default option is a bit mean...
