remoteproc: Pass type of shutdown to subdev remove

2018-02-13T00:57:22+00:00

remoteproc instances can be stopped either by invoking shutdown or by an
attempt to recover from a crash. For some subdev types it's expected to
clean up gracefully during a shutdown, but are unable to do so during a
crash - so pass this information to the subdev remove functions.

remoteproc: Rename "load_rsc_table" to "parse_fw"

2018-02-12T19:05:30+00:00

The resource table is just one possible source of information that can
be extracted from the firmware file. Generalize this interface to allow
drivers to override this with parsers of other types of information.

remoteproc: Add remote processor coredump support

2018-02-12T19:05:29+00:00

As the remoteproc framework restarts the remote processor after a fatal
event, it's useful to be able to acquire a coredump of the remote
processor's state, for post mortem debugging.

This patch introduces a mechanism for extracting the memory contents
after the remote has stopped and before the restart sequence has begun
in the recovery path. The remoteproc framework builds the core dump in
memory and use devcoredump to expose this to user space.

remoteproc: Drop dangling find_rsc_table dummies

2018-01-15T17:30:00+00:00

As the core now deals with the lack of a resource table, remove the
dangling custom dummy implementations of find_rsc_table from drivers.

remoteproc: Move resource table load logic to find

2018-01-15T17:29:53+00:00

Extend the previous operation of finding the resource table in the ELF
with the extra step of populating the rproc struct with a copy and the
size. This allows drivers to override the mechanism used for acquiring
the resource table, or omit it for firmware that is known not to have a
resource table.

This leaves the custom, dummy, find_rsc_table implementations found in
some drivers dangling.

remoteproc: Merge rproc_ops and rproc_fw_ops

2018-01-15T17:29:40+00:00

There are currently a few different schemes used for overriding fw_ops
or parts of fw_ops. Merge fw_ops into rproc_ops and expose the default
ELF-loader symbols so that they can be assigned by the drivers.

To keep backwards compatibility with the "default" case, a driver not
specifying the "load" operation is assumed to want the full ELF-loader
suit of functions.

remoteproc: Clone rproc_ops in rproc_alloc()

2018-01-15T17:29:34+00:00

In order to allow rproc_alloc() to, in a future patch, update entries in
the "ops" struct we need to make a local copy of it.

remoteproc: Cache resource table size

2018-01-15T17:29:29+00:00

We don't re-read the resource table during a recovery, so it is possible
in the recovery path that the resource table has a different size than
cached_table. Store the original size of cached_table to avoid these
getting out of sync.

remoteproc: Remove depricated crash completion

2018-01-15T17:29:16+00:00

The crash handling now happens in a single execution context, so there's
no longer a need for a completion to synchronize this.
