MORIN Date: Wed, 9 Mar 2016 00:16:12 +0100 Subject: [Buildroot] [PATCH] package/busybox: support automatic module loading with mdev In-Reply-To: <1457478205-18515-1-git-send-email-peter@korsgaard.com> References: <1457478205-18515-1-git-send-email-peter@korsgaard.com> Message-ID: <20160308231612.GF14289@free.fr> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: buildroot@busybox.net Peter, All, On 2016-03-09 00:03 +0100, Peter Korsgaard spake thusly: > A recently discussed on the mailing list: > http://lists.busybox.net/pipermail/buildroot/2016-February/154189.html > > Our mdev configuration currently doesn't handle module loading. Fix that by: > > - Telling mdev to run modprobe on hotplug events providing MODALIAS > > - Adjust the init script to handle coldplug modalias events (E.G. modules > for which the devices were already present before mdev was added as the > hotplug handler). mdev -s should arguable handle this, but it doesn't. > > Cc: Arnout Vandecappelle > Signed-off-by: Peter Korsgaard Acked-by: "Yann E.
