Why This File Exists

Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.

• Top-level or miscellaneous repository surface. Use this as map coverage unless a later manual pass promotes the file into a deeper subsystem dossier.
• Uses kernel synchronization; read lock ordering, sleepability, and interrupt context assumptions before translating.
• Defines or uses C structs; map object ownership, embedded links, reference counts, and lock ownership.

Dependency Surface

• linux/types.h

Detected Declarations

• struct drm_atomic_commit
• struct drm_connector
• struct drm_crtc
• struct drm_device
• struct drm_display_mode
• struct drm_encoder
• struct drm_framebuffer
• struct drm_mode_set
• struct drm_modeset_acquire_ctx

Annotation

• Immediate include surface: `linux/types.h`.
• Detected declarations: `struct drm_atomic_commit`, `struct drm_connector`, `struct drm_crtc`, `struct drm_device`, `struct drm_display_mode`, `struct drm_encoder`, `struct drm_framebuffer`, `struct drm_mode_set`, `struct drm_modeset_acquire_ctx`.
• Atlas domain: Repository Root And Misc / include.
• Implementation status: source implementation candidate.
• Synchronization appears in or near this file; preserve lock ordering, sleepability, and interrupt-context constraints.

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.
