2025-11-26drm/tests: Add a few tests around drm_fixed.hHarry Wentland
While working on the CTM implementation of VKMS I had to ascertain myself of a few assumptions. One of those is whether drm_fixed.h treats its numbers using signed-magnitude or twos-complement. It is twos-complement. In order to make someone else's day easier I am adding the drm_test_int2fixp test that validates the above assumption. I am also adding a test for the new sm2fixp function that converts from a signed-magnitude fixed point to the twos-complement fixed point.

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.

2022-12-23drm/tests: reduce drm_mm_test stack usageArnd Bergmann
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.

2022-11-24drm/probe-helper: Provide a TV get_modes helperNoralf Trønnes
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.

2022-11-24drm/modes: Add a function to generate analog display modesMaxime Ripard
Multiple drivers (meson, vc4, sun4i) define analog TV 525-lines and 625-lines modes in their drivers. Since those modes are fairly standard, and that we'll need to use them in more places in the future, it makes sense to move their definition into the core framework. However, analog display usually have fairly loose timings requirements, the only discrete parameters being the total number of lines and pixel clock frequency. Thus, we created a function that will create a display mode from the standard, the pixel frequency and the active area.
