You can enable it via ``-M q35,pic=off`` which\n+disables the PIC. In that configuration, using a UEFI is recommended.\n \n-Workaround: for affected use cases, use ``-M kernel-irqchip=off``.\n+On this release, ``-M kernel-irqchip=`` is not expected to be manually\n+set during normal operation. It remains as a debugging option.\n \n Known issues on Windows 11\n ^^^^^^^^^^^^^^^^^^^^^^^^^^\n", "prefixes": [ "38/38" ] }
