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 v6:
- Use guard() helper function for svc_mem_lock.
- Fixed comment message style according to kernel coding style.
- Added fixes tag to commit message.
- Removed id generation patch and use in house ida allocator.
- Changed lock of hashmap db lock from rcu to spinlock for better latency.

Changes in v5:
- Use FIELD_PREP, FIELD_GET() and GENMASK() for bit
manipulation for ids.
- Bring down probing when stratix10_svc_async_init()
fails.
- Other minor fixes.
- Link to v4: https://lore.kernel.org/r/20250610-sip_svc_upstream-v4-0-bcd9d6089071@altera.com
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.
- Link to v3: https://lore.kernel.org/r/20250526-sip_svc_upstream-v3-0-6a08a4502de3@altera.com
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.
- Link to v2: https://lore.kernel.org/r/20250512-sip_svc_upstream-v2-0-fae5c45c059d@altera.com
Changes in v2:
- Added Reviewed by tag from Rob Herring for dt-binding
patch.
- Resending the patch-set as there is no response from
the maintainers for the previous patch submission.

Sorry for the delayed response, as I was on vacation last week. Sure, I will rebase the patchset onto svc_driver_for_v6.19 and re share. > > Thanks, > Dinh
