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.

	  Build support for the Innova family of network cards by Mellanox
	  Technologies. Innova network cards are comprised of a ConnectX chip
	  and an FPGA chip on one board. If you select this option, the
	  mlx5_core driver will include the Innova FPGA core and allow building
	  sandbox-specific client drivers.

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.
