[PATCH] hw/acpi: increase default size for rsdp file

Posted by shenjiatong 5 months, 2 weeks ago

From: shenjiatong <yshxxsjt715@gmail.com>

Size of RSDP file will be different on an OS
configured with PAGE_SIZE of 64 KiB. This will
eventually blocks live migration from a different
hosts which has the same haredware spec. So increase
this default max size to 0x10000 (64 KiB).
