Annotated Snippet
What: /sys/class/stm/<stm>/masters
Date: June 2015
KernelVersion: 4.3
Contact: Alexander Shishkin <alexander.shishkin@linux.intel.com>
Description:

this STM device.
What: /sys/class/stm/<stm>/channels
Date: June 2015
KernelVersion: 4.3
Contact: Alexander Shishkin <alexander.shishkin@linux.intel.com>
Description:
Shows the number of channels per master on this STM device.
What: /sys/class/stm/<stm>/hw_override
Date: March 2016
KernelVersion: 4.7
Contact: Alexander Shishkin <alexander.shishkin@linux.intel.com>
Description:
Reads as 0 if master numbers in the STP stream produced by
this stm device will match the master numbers assigned by
the software or 1 if the stm hardware overrides software
assigned masters.Annotation
- Atlas domain: Support Tooling And Documentation / Documentation.
- Implementation status: atlas-only.
Implementation Notes
- This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
- Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
- Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
