Guard the division against a zero tile_cols by\ninitialising the context-update values to zero and computing them only\nwhen tile_cols is non-zero, and stop the descriptor writes once the\ntile_info buffer is full. The tile geometry written to the hardware\nregisters is left unmodified; the per-dimension and total tile bounds are\nenforced by the control validation.",
