[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v8 01/16] tools/libxl: Add an unified configuration option for ACPI
Since the existing configuration option "u.hvm.acpi" is x86 specific and
we want to reuse it on ARM as well, add a unified option "acpi" for
x86 and ARM, and for ARM it's disabled by default.
