Bug Description

SRU Justification:

[Impact]

mlxbf-ptm is a kernel driver that provides debufgs interface for system software to monitor Bluefield devices' power and thermal management parameters.

[Fix]

* This change adds additional debugfs nodes that provide ATX status and power profile data. Replaces S_IRUGO with 0444 inline with checkpatch expectation.

[Test Case]

* After installing the kernel module, debugfs entry at /sys/kernel/debug/mlxbf-ptm will be created
* monitors/status folder contains read-only parameters reported from the Bluefield device

[Regression Potential]

* Minimal - as these are read-only parameters that report Bluefield device information.

[Other]
* This code is likely to change depending on feedback we received from maintainers.

This bug is awaiting verification that the linux-bluefield/5.15.0-1015.17 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-jammy' to 'verification-done-jammy'. If the problem still exists, change the tag 'verification-needed-jammy' to 'verification-failed-jammy'.

If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!
