^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 327) This option disables the default workaround for GPU2017-1336. The
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 328) workaround keeps the L2 cache powered up except for powerdown and reset.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 330) The workaround introduces a limitation that will prevent the running of
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 331) protected mode content on fully coherent platforms, as the switch to IO
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 332) coherency mode requires the L2 to be turned off.
