2 bool "Force GCC to throw an error instead of a warning when compiling"
3 # As this may inadvertently break the build, only allow the user
4 # to shoot oneself in the foot iff they aim really hard
6 # We use the dependency on !COMPILE_TEST to not be enabled in
7 # allmodconfig or allyesconfig configurations
8 depends on !COMPILE_TEST
11 Add -Werror to the build flags for (and only for) i915.ko.
12 Do not enable this unless you are writing code for the i915.ko module.
14 Recommended for driver developers only.
19 bool "Enable additional driver debugging"
23 select DRM_DP_AUX_CHARDEV
24 select X86_MSR # used by igt/pm_rpm
25 select DRM_VGEM # used by igt/prime_vgem (dmabuf interop checks)

27 select DRM_DEBUG_MM_SELFTEST
28 select DRM_I915_SW_FENCE_DEBUG_OBJECTS
29 select DRM_I915_SELFTEST
32 Choose this option to turn on extra driver debugging that may affect
33 performance but will catch some internal issues.
35 Recommended for driver developers only.
39 config DRM_I915_DEBUG_GEM
40 bool "Insert extra checks into the GEM internals"
42 depends on DRM_I915_WERROR
44 Enable extra sanity checks (including BUGs) along the GEM driver
45 paths that may slow the system down and if hit hang the machine.
47 Recommended for driver developers only.
51 config DRM_I915_SW_FENCE_DEBUG_OBJECTS
52 bool "Enable additional driver debugging for fence objects"
57 Choose this option to turn on extra driver debugging that may affect
58 performance but will catch some internal issues.
60 Recommended for driver developers only.
64 config DRM_I915_SELFTEST
65 bool "Enable selftests upon driver load"
68 select FAULT_INJECTION
71 Choose this option to allow the driver to perform selftests upon
72 loading; also requires the i915.selftest=1 module parameter. To
73 exit the module after running the selftests (i.e. to prevent normal
74 module initialisation afterwards) use i915.selftest=-1.
76 Recommended for driver developers only.
80 config DRM_I915_LOW_LEVEL_TRACEPOINTS
81 bool "Enable low level request tracing events"
85 Choose this option to turn on low level request tracing events.
86 This provides the ability to precisely monitor engine utilisation
87 and also analyze the request dependency resolving timeline.
91 config DRM_I915_DEBUG_VBLANK_EVADE
92 bool "Enable extra debug warnings for vblank evasion"
96 Choose this option to turn on extra debug warnings for the
97 vblank evade mechanism. This gives a warning every time the
98 the deadline allotted for the vblank evade critical section
99 is exceeded, even if there isn't an actual risk of missing
102 If in doubt, say "N".
