[PATCH v4 0/5] In-kernel QMI helpers and sysmon

From: Bjorn Andersson
Date: Wed Nov 29 2017 - 20:16:57 EST


This series introduces a helper library for drivers that needs to implement
clients or services in the kernel for communicating with QMI encoded messages.

This is used by a set of drivers in order to implement control signaling that
needs to happen between a driver and a service on a remote processor, such as
the synchronization of states during a remoteproc shutdown/restart; as seen in
the sysmon implementation.

Finally a sample driver provides an implementation of the "test" protocol,
which is a service typically implemented by Qualcomm remoteproc firmware.

Changes since v3:
- Don't call QMI handler for response type messages without known txn
- Kerneldoc updates
- Style updates

Changes since v2:
- Fix reported typos
- Checkpatch fixes
- Use non-gpl EXPORT_SYMBOL

Changes since v1:
- Lot of modifications to QMI interface, from feedback and implementation and
testing of sysmon.
- Added sysmon driver.
- Added patch for remoteproc to pass gracefulness on subdev remove.
- QRTR patches part of v1 was merged separately
