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.

Annotated Snippet

# SPDX-License-Identifier: GPL-2.0-only
config DRM_XE_WERROR
	bool "Force GCC to throw an error instead of a warning when compiling"
	# As this may inadvertently break the build, only allow the user
	# to shoot oneself in the foot iff they aim really hard
	depends on EXPERT
	# We use the dependency on !COMPILE_TEST to not be enabled in
	# allmodconfig or allyesconfig configurations
	depends on !COMPILE_TEST
	default n
	help
	  Add -Werror to the build flags for (and only for) xe.ko.
	  Do not enable this unless you are writing code for the xe.ko module.

	  Recommended for driver developers only.

	  If in doubt, say "N".

config DRM_XE_DEBUG
	bool "Enable additional driver debugging"
	depends on DRM_XE
	depends on EXPERT
	depends on !COMPILE_TEST
	default n
	help
	  Choose this option to turn on extra driver debugging that may affect
	  performance but will catch some internal issues.

	  Recommended for driver developers only.

	  If in doubt, say "N".

config DRM_XE_DEBUG_VM
	bool "Enable extra VM debugging info"
	default n
	help
	  Enable extra VM debugging info

	  Recommended for driver developers only.

	  If in doubt, say "N".

config DRM_XE_DEBUG_SRIOV
	bool "Enable extra SR-IOV debugging"
	default n
	imply DRM_XE_DEBUG_MEMIRQ
	help
	  Enable extra SR-IOV debugging info.

	  Recommended for driver developers only.

	  If in doubt, say "N".

config DRM_XE_DEBUG_MEMIRQ
	bool "Enable extra memirq debugging"
	default n
	help
	  Choose this option to enable additional debugging info for
	  memory based interrupts.

	  Recommended for driver developers only.

	  If in doubt, say "N".

config DRM_XE_DEBUG_MEM
	bool "Enable passing SYS/VRAM addresses to user space"
	default n
	help
	  Pass object location through uapi. Intended for extended
	  testing and development only.

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.
