When supplying a view to vma_compare() it is required that the supplied i915_address_space is the global GTT. I tested the VMA instead (which is the current position in the rbtree and maybe from any address space). (This reapplies commita44342acde("drm/i915: Fix test on inputs for vma_compare()") as it was lost in the vma split) Reported-by: Matthew Auld <matthew.auld@intel.com> Tested-by: Matthew Auld <matthew.auld@intel.com> Bugzilla: https://bugs.freedesktop.org/show_bug.cgi?id=98579 Fixes:db6c2b4151("drm/i915: Store the vma in an rbtree...")
