Why This File Exists

Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

• Core operating-system implementation surface: boot, tasks, memory, VFS, syscall-facing interfaces, synchronization, credentials, and isolation.

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

#ifndef _UAPI_COUNTER_MCHP_TCB_H_
#define _UAPI_COUNTER_MCHP_TCB_H_

/*
 * The driver defines the following components:
 *
 * Count 0
 * \__  Synapse 0 -- Signal 0 (Channel A, i.e. TIOA)
 * \__  Synapse 1 -- Signal 1 (Channel B, i.e. TIOB)
 * \__  Extension capture0    (RA register)
 * \__  Extension capture1    (RB register)
 *
 * It also supports the following events:
 *
 * Channel 0:
 * - CV register changed
 * - CV overflowed
 * - RA captured
 * Channel 1:
 * - RB captured
 * Channel 2:
 * - RC compare triggered

Annotation

• Atlas domain: Core OS / Core Kernel Interface.
• Implementation status: source implementation candidate.

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.
