From 70b85ef83ce3523f709b622d2c4cb31778686338 Mon Sep 17 00:00:00 2001 From: Fernando Guzman Lugo Date: Thu, 30 Aug 2012 13:26:13 -0500 Subject: remoteproc: add actual recovery implementation Add rproc_trigger_recovery() which takes care of the recovery itself, by removing, and re-adding, all of the remoteproc's virtio devices. This resets all virtio users of the remote processor, during which the remote processor is powered off and on again.
