title: Tegra210 ADMAIF
description: |
ADMAIF is the interface between ADMA and AHUB. Each ADMA channel
that sends/receives data to/from AHUB must interface through an
ADMAIF channel. ADMA channel sending data to AHUB pairs with ADMAIF
Tx channel and ADMA channel receiving data from AHUB pairs with
ADMAIF Rx channel.

Contains list of ACIF (Audio CIF) port nodes for ADMAIF channels.
The number of port nodes depends on the number of ADMAIF channels
that SoC may have. These are interfaced with respective ACIF ports
in AHUB (Audio Hub). Each port is capable of data transfers in
both directions.

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.
