Revert "drm/i915: replace select with dependency for visible DEBUG_OBJECTS"

2026-05-06T14:32:09+00:00

This reverts commit 025f89b01ed8d5e65d87ed54f231e10c6ac08188. 025f89b01ed8 ("drm/i915: replace select with dependency for visible DEBUG_OBJECTS") breaks the build in certain scenarios, presumably because config DRM_I915_DEBUG selects DRM_I915_SW_FENCE_DEBUG_OBJECTS without looking at its dependencies, allowing DRM_I915_SW_FENCE_DEBUG_OBJECTS=y and DEBUG_OBJECTS=n.

drm/i915: replace select with dependency for visible DEBUG_OBJECTS

2026-05-05T13:39:55+00:00

DRM_I915_SW_FENCE_DEBUG_OBJECTS currently selects DEBUG_OBJECTS even though DEBUG_OBJECTS is visible to users. Other config options use 'depends on' for DEBUG_OBJECTS, so let's do the same here. This select-visible Kconfig misusage was detected by Kconfirm, a static analysis tool for Kconfig.

drm/i915: Fix selecting CONFIG_DRM_KUNIT_TEST in debug builds

2025-07-25T08:41:55+00:00

Selecting an option which depends on other options only works if the dependencies are guaranteed to be selected (as these dependencies will not be automatically selected). CONFIG_DRM_KUNIT_TEST depends on DRM, MMU and KUNIT the first two of which are guaranteed to be selected for i915, but the last one is not. Hence, selecting CONFIG_DRM_KUNIT_TEST in i915 debug builds may result in CONFIG_DRM_KUNIT_TEST being selected without the CONFIG_KUNIT dependency being selected. This causes at least the following compile error: drivers/gpu/drm/tests/drm_bridge_test.c: In function ‘drm_test_bridge_alloc_init’: drivers/gpu/drm/tests/drm_bridge_test.c:449:21: error: implicit declaration of function ‘kunit_device_register’; did you mean ‘root_device_register’? [-Werror=implicit-function-declaration] 449 | priv->dev = kunit_device_register(test, "drm-bridge-dev"); Fix the above by selecting CONFIG_DRM_KUNIT_TEST only if CONFIG_KUNIT is also selected.

drm/i915: replace DRM_DEBUG_SELFTEST with DRM_KUNIT_TEST

2025-07-21T14:46:27+00:00

DRM_DEBUG_SELFTEST was removed in commit fc8d29e298cf (drm: selftest: convert drm_mm selftest to KUnit) and all functions under it were converted to KUnit, under the DRM_KUNIT_TEST option This conversion however did not occur in the Kconfig.debug file in the i915 directory. This patch replaces the select for DRM_DEBUG_SELFTEST, an option that no longer exists, with the correct select, DRM_KUNIT_TEST.

drm/i915: Support replaying GPU hangs with captured context image

2024-05-16T07:37:05+00:00

When debugging GPU hangs Mesa developers are finding it useful to replay the captured error state against the simulator. But due various simulator limitations which prevent replicating all hangs, one step further is being able to replay against a real GPU. This is almost doable today with the missing part being able to upload the captured context image into the driver state prior to executing the uploaded hanging batch and all the buffers. To enable this last part we add a new context parameter called I915_CONTEXT_PARAM_CONTEXT_IMAGE. It follows the existing SSEU configuration pattern of being able to select which context to apply against, paired with the actual image and its size. Since this is adding a new concept of debug only uapi, we hide it behind a new kconfig option and also require activation with a module parameter. Together with a warning banner printed at driver load, all those combined should be sufficient to guard against inadvertently enabling the feature. In terms of implementation we allow the legacy context set param to be used since that removes the need to record the per context data in the proto context, while still allowing flexibility of specifying context images for any context. Mesa MR using the uapi can be seen at: https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/27594 v2: * Fix whitespace alignment as per checkpatch. * Added warning on userspace misuse. * Rebase for extracting ce->default_state shadowing. v3: * Rebase for I915_CONTEXT_PARAM_LOW_LATENCY.

drm/display: Make DisplayPort AUX Chardev Kconfig name consistent

2024-03-28T10:26:46+00:00

While most display helpers Kconfig symbols have the DRM_DISPLAY prefix, the DisplayPort-AUX chardev interface uses DRM_DP_AUX_CHARDEV. Since the number of users is limited and it's a selected symbol, we can easily rename it to make it consistent.
