Subject: [PATCH v17 29/35] gunyah: rsc_mgr: Add RPC to set VM boot context
Date: Thu, 22 Feb 2024 15:16:52 -0800 [thread overview]
Message-ID: <20240222-gunyah-v17-29-1e9da6763d38@quicinc.com> (raw)
In-Reply-To: <20240222-gunyah-v17-0-1e9da6763d38@quicinc.com>
The initial context of a the primary vCPU can be initialized by
performing RM RPC calls.
