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/types.h

Detected Declarations

• struct pci_dev
• struct uart_8250_port

Annotated Snippet

#include <linux/types.h>

struct pci_dev;

struct uart_8250_port;

int serial8250_pci_setup_port(struct pci_dev *dev, struct uart_8250_port *port, u8 bar,
		   unsigned int offset, int regshift, void __iomem *iomem);

int serial_8250_warn_need_ioport(struct pci_dev *dev);

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct pci_dev`, `struct uart_8250_port`.
• Atlas domain: Driver Families / drivers/tty.
• 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.
