Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

#define __IA_CSS_MMU_H

/* @file
 * This file contains one support function for invalidating the CSS MMU cache
 */

/* @brief Invalidate the MMU internal cache.
 * @return	None
 *
 * This function triggers an invalidation of the translate-look-aside
 * buffer (TLB) that's inside the CSS MMU. This function should be called
 * every time the page tables used by the MMU change.

Annotation

• Atlas domain: Driver Families / drivers/staging.
• 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.
