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.

Driver for the NVIDIA Tegra host1x hardware.
The Tegra host1x module is the DMA engine for register access to
Tegra's graphics- and multimedia-related modules. The modules served
by host1x are referred to as clients. host1x includes some other
functionality, such as synchronization.

Say yes if kernel should protect command streams from tampering.
If unsure, choose Y.

Annotation
- Atlas domain: Driver Families / drivers/gpu.
- 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.
