Subject: [PATCH 05/37] xen: decouple NUMA from ACPI in Kconfig
Date: Thu, 23 Sep 2021 20:02:04 +0800	[thread overview]
Message-ID: <20210923120236.3692135-6-wei.chen@arm.com> (raw)
In-Reply-To: <20210923120236.3692135-1-wei.chen@arm.com>

In current Xen code only implements x86 ACPI-based NUMA support.
So in Xen Kconfig system, NUMA equals to ACPI_NUMA. x86 selects
NUMA by default, and CONFIG_ACPI_NUMA is hardcode in config.h.

In a follow-up patch, we will introduce support for NUMA using
the device tree. That means we will have two NUMA implementations,
so in this patch we decouple NUMA from ACPI based NUMA in Kconfig.
Make NUMA as a common feature, that device tree based NUMA also
can select it.
