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.

• 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.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/io.h
• linux/platform_device.h
• mtk_vcodec_dec_drv.h

Detected Declarations

• struct mtk_vdec_hw_dev
• enum mtk_vdec_hw_reg_idx

Annotation

• Immediate include surface: `linux/io.h`, `linux/platform_device.h`, `mtk_vcodec_dec_drv.h`.
• Detected declarations: `struct mtk_vdec_hw_dev`, `enum mtk_vdec_hw_reg_idx`.
• Atlas domain: Driver Families / drivers/media.
• 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.
