π dm_test_cp_diff_desired_mode_changed β NAME β¨
okay so bestie, welcome to the <pink>Kernel API Manual</pink> page for dm_test_cp_diff_desired_mode_changed β the KUnit test that checks the DESIRED->DESIRED case with modeset forces true π₯
fr fr that's the whole vibe: it's a test function, it tests a thing, and it wants you to know exactly which thing π
πΈ SYNOPSIS πΈ
void dm_test_cp_diff_desired_mode_changed (struct kunit *test );
that's it, that's the signature, no cap β returns void, takes one arg π
π¦ ARGUMENTS π¦
testβ the KUnit test context π« literally just the context struct the test framework hands you, bestie. that's its whole job.
π SEE ALSO π
okay so this is the part where the manpage dumps the entire friend group π and honestly? iconic. every single one of these is getting listed, no skipping, we don't do that here π
First up, the Kernel file itself, aka where this all lives:
./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_test.c
and now the full squad, in order, exactly as the original lists them π«Ά

like, fifty-five whole tests?? the friend group is LARGE and we love that for them ππ
π one lil sign-off π
this page came from ./drivers/gpu/drm/amd/display/... and it's dated October 2026 β β so yeah, future vibes only, bestie. go forth and test that DESIRED->DESIRED mode change π§ββοΈπ
