Subject: [RFC v1 3/3] luo: x86: Enable live update support
Date: Thu, 20 Mar 2025 02:40:11 +0000 [thread overview]
Message-ID: <20250320024011.2995837-4-pasha.tatashin@soleen.com> (raw)
In-Reply-To: <20250320024011.2995837-1-pasha.tatashin@soleen.com>
Enable the Live Update Orchestrator for the x86 architecture.
It does so by selecting ARCH_SUPPORTS_LIVEUPDATE when KEXEC_HANDOVER is
available, signaling to the LUO core that the architecture provides the
necessary Kexec Handover functionality required for live updates.
