Subject: [PATCH 05/13] rpmsg: uapi: add service param for create destroy ioctls
Date: Fri, 31 Jul 2020 14:10:35 +0200 [thread overview]
Message-ID: <20200731121043.24199-6-arnaud.pouliquen@st.com> (raw)
In-Reply-To: <20200731121043.24199-1-arnaud.pouliquen@st.com>
To allow to associate an endpoint creation to a service, add
a new parameter in rpmsg_endpoint_info struct.
For each RPMsg service driver that want to support the ioctl interface
a new service will have to be added.
The RPMSG_START_PRIVATE_SERVICES is used to allow developer to add is
own services with ID higher or equal to 1024.
