Subject: [PATCH v2 16/16] rpmsg: virtio: allocate buffer from parent
Date: Thu, 30 Nov 2017 17:46:51 +0100 [thread overview]
Message-ID: <1512060411-729-17-git-send-email-loic.pallardy@st.com> (raw)
In-Reply-To: <1512060411-729-1-git-send-email-loic.pallardy@st.com>
Remoteproc is now capable to create one specific sub-device per
virtio link to associate a dedicated memory pool.
This implies to change device used by virtio_rpmsg for
buffer allocation from grand-parent to parent.
