[ Upstream commit b327c72753d6a78de37aed6c35756f2ef62897ee ] 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().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
