Subject: [PATCH v2 12/14] arm64: realm: Support nonsecure ITS emulation shared
Date: Fri, 12 Apr 2024 09:42:11 +0100	[thread overview]
Message-ID: <20240412084213.1733764-13-steven.price@arm.com> (raw)
In-Reply-To: <20240412084213.1733764-1-steven.price@arm.com>

Within a realm guest the ITS is emulated by the host. This means the
allocations must have been made available to the host by a call to
set_memory_decrypted(). Introduce an allocation function which performs
this extra call.
