drm/tests: Add output bpc tests

2024-05-28T08:09:38+00:00

Now that we're tracking the output bpc count in the connector state, let's add a few tests to make sure it works as expected.

drm/test: add a test suite for GEM objects backed by shmem

2023-12-04T08:32:25+00:00

This patch introduces an initial KUnit test suite for GEM objects backed by shmem buffers. Suggested-by: Javier Martinez Canillas Signed-off-by: Marco Pagani v5: - using __drm_kunit_helper_alloc_drm_device() to avoid local struct v4: - Add missing MMU dependency for DRM_GEM_SHMEM_HELPER (kernel test robot) v3: - Explicitly cast pointers in the helpers - Removed unused pointer to parent dev in struct fake_dev - Test entries reordering in Kconfig and Makefile sent as a separate patch v2: - Improved description of test cases - Cleaner error handling using KUnit actions - Alphabetical order in Kconfig and Makefile Signed-off-by: Maxime Ripard Link: https://patchwork.freedesktop.org/patch/msgid/20231130171417.74162-1-marpagan@redhat.com

Merge v6.2-rc6 into drm-next

2023-01-31T11:23:23+00:00

Due to holidays we started -next with more -fixes in-flight than usual, and people have been asking where they are. Backmerge to get things better in sync. Conflicts: - Tiny conflict in drm_fbdev_generic.c between variable rename and missing error handling that got added. - Conflict in drm_fb_helper.c between the added call to vgaswitcheroo in drm_fb_helper_single_fb_probe and a refactor patch that extracted lots of helpers and incidentally removed the dev local variable. Readd it to make things compile. Signed-off-by: Daniel Vetter

drm/tests: reduce drm_mm_test stack usage

2022-12-23T22:08:26+00:00

The check_reserve_boundaries function uses a lot of kernel stack, and it gets inlined by clang, which makes __drm_test_mm_reserve use even more of it, to the point of hitting the warning limit: drivers/gpu/drm/tests/drm_mm_test.c:344:12: error: stack frame size (1048) exceeds limit (1024) in '__drm_test_mm_reserve' [-Werror,-Wframe-larger-than] When building with gcc, this does not happen, but the structleak plugin can similarly increase the stack usage and needs to be disabled, as we do for all other kunit users.

drm/tests: Add a test for DRM managed actions

2022-12-08T08:56:55+00:00

DRM-managed actions are supposed to be ran whenever the device is released. Let's introduce a basic unit test to make sure it happens.

drm/tests: Introduce a config option for the KUnit helpers

2022-12-08T08:41:27+00:00

Driver-specific tests will need access to the helpers without pulling every DRM framework test. Let's create an intermediate Kconfig options for the helpers.

drm/probe-helper: Provide a TV get_modes helper

2022-11-24T11:42:40+00:00

Most of the TV connectors will need a similar get_modes implementation that will, depending on the drivers' capabilities, register the 480i and 576i modes. That implementation will also need to set the preferred flag and order the modes based on the driver and users preferrence. This is especially important to guarantee that a userspace stack such as Xorg can start and pick up the preferred mode while maintaining a working output.

drm/connector: Add a function to lookup a TV mode by its name

2022-11-24T11:42:39+00:00

As part of the command line parsing rework coming in the next patches, we'll need to lookup drm_connector_tv_mode values by their name, already defined in drm_tv_mode_enum_list. In order to avoid any code duplication, let's do a function that will perform a lookup of a TV mode name and return its value.
