Subject[PATCH 4.19 20/67] drm/amdgpu: wait for IB test on first device open
Date
4.19-stable review patch.  If anyone has any objections, please let me know.

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

[ Upstream commit 3bfa8897e4d08f822d1d58cf6cbbffbccef82e08 ]

Instead of delaying that to the first query. Otherwise we could try to use the
SDMA for VM updates before the IB tests are done.
