[igt-dev] [PATCH igt 4/4] tests/xe_debugfs: skip page table level check for Xe2

[Lucas De Marchi <lucas.demarchi@intel.com>]

From: Janga Rahul Kumar <janga.rahul.kumar@intel.com>

Starting with Xe2, a 5-level page table is always used, regardless of
the actual virtual address range supported by the platform. Do not
depend on VA range to configure max page table level.
