remoteproc: qcom: expose types for COMPILE_TEST

2021-01-09T21:51:36Z

Stub functions are defined for SSR notifier registration in case QCOM_RPROC_COMMON is not configured. As a result, code that uses these functions can link successfully even if the common remoteproc code is not built. Code that registers an SSR notifier function likely needs the types defined in "qcom_rproc.h", but those are only exposed if QCOM_RPROC_COMMON is enabled. Rearrange the conditional definition so the qcom_ssr_notify_data structure and qcom_ssr_notify_type enumerated type are defined whether or not QCOM_RPROC_COMMON is enabled.

remoteproc: kill IPA notify code

2020-07-29T00:11:02Z

The IPA code now uses the generic remoteproc SSR notification mechanism. This makes the original IPA notification code unused and unnecessary, so get rid of it. This is effectively a revert of commit d7f5f3c89c1a ("remoteproc: add IPA notification to q6v5 driver").

remoteproc: qcom: Add notification types to SSR

2020-07-09T04:45:17Z

The SSR subdevice only adds callback for the unprepare event. Add callbacks for prepare, start and prepare events. The client driver for a particular remoteproc might be interested in knowing the status of the remoteproc while undergoing SSR, not just when the remoteproc has finished shutting down.

remoteproc: qcom: Add per subsystem SSR notification

2020-07-09T04:45:03Z

Currently there is a single notification chain which is called whenever any remoteproc shuts down. This leads to all the listeners being notified, and is not an optimal design as kernel drivers might only be interested in listening to notifications from a particular remoteproc. Create a global list of remoteproc notification info data structures. This will hold the name and notifier_list information for a particular remoteproc. The API to register for notifications will use name argument to retrieve the notification info data structure and the notifier block will be added to that data structure's notification chain. Also move from blocking notifier to srcu notifer based implementation to support dynamic notifier head creation.

remoteproc: add IPA notification to q6v5 driver

2020-03-09T05:07:09Z

Set up a subdev in the q6v5 modem remoteproc driver that generates event notifications for the IPA driver to use for initialization and recovery following a modem shutdown or crash. A pair of new functions provides a way for the IPA driver to register and deregister a notification callback function that will be called whenever modem events (about to boot, running, about to shut down, etc.) occur. A void pointer value (provided by the IPA driver at registration time) and an event type are supplied to the callback function. One event, MODEM_REMOVING, is signaled whenever the q6v5 driver is about to remove the notification subdevice. It requires the IPA driver de-register its callback. This sub-device is only used by the modem subsystem (MSS) driver, so the code that adds the new subdev and allows registration and deregistration of the notifier is found in "qcom_q6v6_mss.c".

remoteproc: qcom: Add support for SSR notifications

2017-08-02T19:43:20Z

This adds the remoteproc part of subsystem restart, which is responsible for emitting notifications to other processors in the system about a dying remoteproc instance. These notifications are propagated to the various communication systems in the various remote processors to shut down communication links that was left in a dangling state as the remoteproc was stopped (or crashed).
