Help text

Expose a debugfs knob to override user BO page-size allocation handling for validation and debug. Supported modes include forced 2M, forced 1G, and a mixed mode that exercises 4K, 64K, 2M, and 1G page-size paths on platforms that support them.

This is an unstable debugfs interface intended for development and validation only. Its layout, contents, and existence may change or be removed at any time with no regression warranty.

Recommended for driver developers only. If in doubt, say "N".
