Subject: [PATCH 0/1 v2] rpmsg: char - treat `ENOMEM` as `EAGAIN`
Date: Sun, 13 Mar 2022 10:45:40 +0800 [thread overview]
Message-ID: <20220313024541.1579848-1-tim@klingt.org> (raw)

This patch should allow the use of `rpmsg_char` character devices with
libraries that do a `poll`/`write` loop and expect `EAGAIN` when sending
fails and the user space application needs to `poll` to wait for more
space to be available.
`boost::asio::write` is a notable example of a library, which implements
such a loop.
