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/notifier.h

Detected Declarations

• function iosf_mbi_available
• function iosf_mbi_read
• function iosf_mbi_write
• function iosf_mbi_modify
• function iosf_mbi_punit_acquire
• function iosf_mbi_unregister_pmic_bus_access_notifier
• function iosf_mbi_unregister_pmic_bus_access_notifier_unlocked

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.
