[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH for-4.19? v5 09/10] xen/x86: Disallow creating domains with altp2m enabled and altp2m.nr == 0
From: Petr Beneš <w1benny@xxxxxxxxx> Since libxl finally sends the altp2m.nr value, we can remove the previously introduced temporary workaround. Creating domain with enabled altp2m while setting altp2m.nr == 0 doesn't make sense and it's probably not what user wants.
