When a remote processor that was attached to is stopped, special care must be taken to make sure the shutdown process is similar to what it would be had it been started by the remoteproc core. This patch takes care of that by making a copy of the resource table currently used by the remote processor. From that point on the copy is used, as if the remote processor had been started by the remoteproc core. Signed-off-by:

If it is possible to detach the remote processor, keep an untouched copy of the resource table. That way we can start from the same resource table without having to worry about original values or what elements the startup code has changed when re-attaching to the remote processor. Signed-off-by:

Introduce function __rproc_detach() to perform the same kind of operation as rproc_stop(), but instead of switching off the remote processor using rproc->ops->stop(), it uses rproc->ops->detach(). That way it is possible for the core to release the resources associated with a remote processor while the latter is kept operating. Signed-off-by:

Move the setting of the resource table installed by an external entity to rproc_ops::get_loaded_rsc_table(). This is to support scenarios where a remote processor has been attached to but is detached at a later stage. To re-attach the remote processor, the address of the resource table needs to be available at a later time than the platform driver's probe() function. Signed-off-by:

Add a new get_loaded_rsc_table() operation in order to support scenarios where the remoteproc core has booted a remote processor and detaches from it. When re-attaching to the remote processor, the core needs to know where the resource table has been placed in memory. Signed-off-by:

There is a need to know when a remote processor has been attached to rather than booted by the remoteproc core. In order to avoid manipulating two variables, i.e rproc::autonomous and rproc::state, get rid of the former and simply use the newly introduced RPROC_ATTACHED state. Signed-off-by:

Whether started at probe() time or thereafter from the command line, a remote processor needs to be shut down before the final cleanup phases can happen. Otherwise the system may be left in an unpredictable state where the remote processor is expecting the remoteproc core to be providing services when in fact it no longer exist. Invariably calling rproc_shutdown() is fine since it will return immediately if the remote processor has already been switched off. Signed-off-by:

There are four different callback functions that are used for the rproc_handle_resource_t callback that all have different second parameter types. rproc_handle_vdev -> struct fw_rsc_vdev rproc_handle_trace -> struct fw_rsc_trace rproc_handle_devmem -> struct fw_rsc_devmem rproc_handle_carveout -> struct fw_rsc_carveout These callbacks are cast to rproc_handle_resource_t so that there is no error about incompatible pointer types. Unfortunately, this is a Clang's Control-Flow Integrity checking violation, which verifies that the callback function's types match the prototypes exactly before jumping.
