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.

DRM driver for coreboot-provided framebuffers.
This driver assumes that the display hardware has been initialized
by coreboot firmware before the kernel boots. Scanout buffer, size,
and display format must be provided via coreboot framebuffer device.

DRM driver for EFI framebuffers.
This driver assumes that the display hardware has been initialized

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.
