However, its implementation fell short in addressing scenarios where both i915 and Xe were present in the system. To address these limitations, intel_sysfs_debugfs will be replaced by a more modular and comprehensive set of tests: - tests/core_debugfs (gpu agnostic) - tests/core_sysfs (gpu agnostic) - tests/intel/xe_debugfs (complementary to core_debugfs) This restructuring ensures better test coverage and flexibility moving forward.
