Hi, it seems that the loop in i915_gem_init_aliasing_ppgtt() over pd_entries that calculates pt_addr does nothing after the commit 55a254ac in the !dmar case. Would it be better to move needs_dmar check over the whole loop ? -------------- next part -------------- A non-text attachment was scrubbed...
