Hi everyone, In preparation for ConfigFS support, a flexible way to configure VKMS device(s) is required. This series adds the required APIs to create a configuration, the code changes required to apply it and KUnit test validating the changes. Louis Chauvet and I are working on ConfigFS support. In this series I tried to merge his changes [1] with mine [2]. I kept his Signed-off-by to reflect that, even if I show up as the author of some/most of the patches, this was a joint effort. I'll send the the ConfigFS code [3] and its IGT tests [4] code this or next week. Meanwhile, the IGT tests also exercise this series and can be used for additional test coverage. Best wishes, José Expósito [1] https://patchwork.kernel.org/project/dri-devel/cover/20250121-google-remove-crtc-index-from-parameter-v3-0-cac00a3c3544@xxxxxxxxxxx/ [2] https://patchwork.kernel.org/project/dri-devel/cover/20240813105134.17439-1-jose.exposito89@xxxxxxxxx/ [3] https://github.com/JoseExposito/linux/commits/patch-vkms-configfs/ [4] https://gitlab.freedesktop.org/jexposit/igt-gpu-tools/-/commits/vkms-configfs Changes in v2: - Applied review comments by Louis Chauvet (thanks!!): - Added Co-developped-by tags where required - Split the first patch in 2: vkms_connector.h/c creation and struct vkms_connector creation - Fixes a user after free/double free bug. The bug is already present in drm-misc-next and the fix could be merged independently - Implemented for_each macros for the config - Other naming fixes - Link to v1: https://lore.kernel.org/all/20250129110059.12199-1-jose.exposito89@xxxxxxxxx/ José Expósito (14): drm/vkms: Fix use after free and double free on init error drm/vkms: Extract vkms_connector header drm/vkms: Create vkms_connector struct drm/vkms: Add KUnit test scaffolding drm/vkms: Extract vkms_config header drm/vkms: Move default_config creation to its own function drm/vkms: Set device name from vkms_config drm/vkms: Allow to configure multiple planes drm/vkms: Allow to configure multiple CRTCs drm/vkms: Allow to attach planes and CRTCs drm/vkms: Allow to configure multiple encoders drm/vkms: Allow to attach encoders and CRTCs drm/vkms: Allow to configure multiple connectors drm/vkms: Allow to attach connectors and encoders Louis Chauvet (1): drm/vkms: Add a validation function for VKMS configuration .clang-format | 7 + drivers/gpu/drm/vkms/Kconfig | 15 + drivers/gpu/drm/vkms/Makefile | 5 +- drivers/gpu/drm/vkms/tests/.kunitconfig | 4 + drivers/gpu/drm/vkms/tests/Makefile | 3 + drivers/gpu/drm/vkms/tests/vkms_config_test.c | 826 ++++++++++++++++++ drivers/gpu/drm/vkms/vkms_config.c | 606 +++++++++++++ drivers/gpu/drm/vkms/vkms_config.h | 429 +++++++++ drivers/gpu/drm/vkms/vkms_connector.c | 61 ++ drivers/gpu/drm/vkms/vkms_connector.h | 26 + drivers/gpu/drm/vkms/vkms_drv.c | 60 +- drivers/gpu/drm/vkms/vkms_drv.h | 19 +- drivers/gpu/drm/vkms/vkms_output.c | 176 ++-- 13 files changed, 2089 insertions(+), 148 deletions(-) create mode 100644 drivers/gpu/drm/vkms/tests/.kunitconfig create mode 100644 drivers/gpu/drm/vkms/tests/Makefile create mode 100644 drivers/gpu/drm/vkms/tests/vkms_config_test.c create mode 100644 drivers/gpu/drm/vkms/vkms_config.c create mode 100644 drivers/gpu/drm/vkms/vkms_config.h create mode 100644 drivers/gpu/drm/vkms/vkms_connector.c create mode 100644 drivers/gpu/drm/vkms/vkms_connector.h -- 2.48.1
