Joakim Zhang 30532a4fd0 remoteproc: virtio: Fix wdg cannot recovery remote processor ... [ Upstream commit b327c72753 ] Recovery remote processor failed when wdg irq received: [ 0.842574] remoteproc remoteproc0: crash detected in cix-dsp-rproc: type watchdog [ 0.842750] remoteproc remoteproc0: handling crash #1 in cix-dsp-rproc [ 0.842824] remoteproc remoteproc0: recovering cix-dsp-rproc [ 0.843342] remoteproc remoteproc0: stopped remote processor cix-dsp-rproc [ 0.847901] rproc-virtio rproc-virtio.0.auto: Failed to associate buffer [ 0.847979] remoteproc remoteproc0: failed to probe subdevices for cix-dsp-rproc: -16 The reason is that dma coherent mem would not be released when recovering the remote processor, due to rproc_virtio_remove() would not be called, where the mem released. It will fail when it try to allocate and associate buffer again. Releasing reserved memory from rproc_virtio_dev_release(), instead of rproc_virtio_remove().
