Why This File Exists

CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.

• CPU and platform-specific kernel glue: boot entry, traps, syscall entry, interrupts, page tables, context switch, and low-level barriers.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/arm_mpam.h
• linux/bitfield.h
• linux/jump_label.h
• linux/percpu.h
• linux/sched.h
• asm/sysreg.h

Detected Declarations

• function __mpam_regval
• function mpam_set_cpu_defaults
• function mpam_thread_switch
• function mpam_set_task_partid_pmg
• function mpam_thread_switch
• function mpam_thread_switch

Annotated Snippet

Annotation

• Immediate include surface: `linux/arm_mpam.h`, `linux/bitfield.h`, `linux/jump_label.h`, `linux/percpu.h`, `linux/sched.h`, `asm/sysreg.h`.
• Detected declarations: `function __mpam_regval`, `function mpam_set_cpu_defaults`, `function mpam_thread_switch`, `function mpam_set_task_partid_pmg`, `function mpam_thread_switch`, `function mpam_thread_switch`.
• Atlas domain: Architecture Layer / arch/arm64.
• 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.
