[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH v1 06/20] acpi/hvmloader: Collect processor and NUMA info in hvmloader
No need for ACPI code to rely on hvm_info.
Signed-off-by: Boris Ostrovsky <boris.ostrovsky@xxxxxxxxxx>

Changes in v1:
* Pass hvm_info_table pointer in acpi_config
