[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v4 03/16] libxl/arm: Generate static ACPI DSDT table
From: Shannon Zhao <shannon.zhao@xxxxxxxxxx>
It uses static DSDT table like the way x86 uses. Currently the DSDT
table only contains processor device objects and it generates the
maximal objects which so far is 128.
Also only check iasl for aarch64 in configure since ACPI on ARM32 is not
supported.
