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.
• Allocates kernel memory; connect allocation flags and lifetime to context constraints.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• iosm_ipc_chnl_cfg.h
• iosm_ipc_imem_ops.h
• iosm_ipc_port.h

Detected Declarations

• function Copyright
• function ipc_port_ctrl_stop
• function ipc_port_ctrl_tx
• function ipc_port_deinit

Annotated Snippet

if (port[ctrl_chl_nr]) {
			ipc_port = port[ctrl_chl_nr];
			wwan_remove_port(ipc_port->iosm_port);
			kfree(ipc_port);
		}
	}
}

Annotation

• Immediate include surface: `iosm_ipc_chnl_cfg.h`, `iosm_ipc_imem_ops.h`, `iosm_ipc_port.h`.
• Detected declarations: `function Copyright`, `function ipc_port_ctrl_stop`, `function ipc_port_ctrl_tx`, `function ipc_port_deinit`.

• 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.
