Subject: [PULL 25/34] i386/cpu: Support module level cache topology
Date: Thu, 27 Feb 2025 15:19:43 +0100	[thread overview]
Message-ID: <20250227141952.811410-26-pbonzini@redhat.com> (raw)
In-Reply-To: <20250227141952.811410-1-pbonzini@redhat.com>

From: Zhao Liu <zhao1.liu@intel.com>

Allow cache to be defined at the module level. This increases
flexibility for x86 users to customize their cache topology.
