From: Mahesh Rao via B4 Relay
Date: Tue Jun 10 2025 - 11:41:52 EST


The patch set includes the following changes:

- Add protection for querying memory objects in
multi-threaded flow.
- Add support to generate and maintain message id
and client id for asynchronous communication with SDM.
- Add framework to communicate with Secure Device
Manager(SDM) asynchronously by sending a request
and polling for response.
- Add commands for performing Remote System Update
(RSU) operations asynchronously.
- Migrate RSU driver to use the asynchronous
communication framework.

Changes in v4:
- Added description for svc_mem_lock mutex.
- Wrapped commit message and comments in source
code to kernel coding style as per coding style.
- Added minor code fixes.
- Moved variables to the top of the function
- Removed HWMON support from in the patch-set, this
will be sent in a separate patch-set.
- Added support for RSU commands to asynchronously
communicate with SDM.
- Migrated RSU driver to use the supported
asynchronous commands.

Changes in v3:
- Changed "Stratix 10" to "Stratix10" in the commit
message and in source code.
- Simplified stratix10_svc_add_async_client() by removing
redundant code for async common channel initialization.
- Fixed resource cleanup on negative path in
stratix10_svc_remove_async_client() and stratix10_svc_async_init().
- Removed optional interrupt handler support, will send the patches
in a separate patch-set.
