Why This File Exists

Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

• Repository support layer: documentation, build tooling, samples, user-space helper tools, generated initramfs support, licenses, and validation utilities.

Dependency Surface

• No C-style include directives detected by the generator.

Detected Declarations

• No top-level syscall, struct, function, initcall, or export declaration detected by the generator.

Annotated Snippet

The ARC700 can be configured with a pipeline performance monitor for counting
CPU and cache events like cache misses and hits. Like conventional PCT there
are 100+ hardware conditions dynamically mapped to up to 32 counters

Note that:
 * The ARC 700 PCT does not support interrupts; although HW events may be
   counted, the HW events themselves cannot serve as a trigger for a sample.

Required properties:

- compatible : should contain
	"snps,arc700-pct"

Example:

pmu {
        compatible = "snps,arc700-pct";
};

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.
