Annotated Snippet

.. _drm/i915:

===========================
 drm/i915 Intel GFX Driver
===========================

The drm/i915 driver supports all (with the exception of some very early
models) integrated GFX chipsets with both Intel display and rendering
blocks. This excludes a set of SoC platforms with an SGX rendering unit,
those have basic support through the gma500 drm driver.

The display, or :ref:`drm-kms`, support for drm/i915 is provided by
:ref:`drm/intel-display`, and shared with :ref:`drm/xe <drm/xe>`.

Core Driver Infrastructure
==========================

This section covers core driver infrastructure used by both the display
and the GEM parts of the driver.

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.
