💅 dm_test_plane_destroy_state_minimal(9) 💅

okay so bestie, welcome to the Kernel API Manual, section 9 — this one's a little kernel test that lives in the kernel's own testing universe and it is, genuinely, so important. let's get into it 🫶

✨ NAME ✨

dm_test_plane_destroy_state_minimal — verify destroy of a minimal state. that's it, that's the whole vibe: it checks that destroying a minimal state actually works. iconique.

🎀 SYNOPSIS 🎀

void dm_test_plane_destroy_state_minimal (struct kunit *test );

🌸 ARGUMENTS 🌸

  • test — the KUnit test context. it's the little backstage pass that tells the test framework who it's working with, and yes it is literally required 💜

🦋 DESCRIPTION 🦋

so here's the tea ☕ — this test verifies that amdgpu_dm_plane_drm_plane_destroy_state tears down a plane state that has no color blobs or DC plane state attached, and that it does it without dereferencing NULL resources. no NULL pointer chaos, no crash, no "not me getting a kernel panic in the group chat" moment. it just cleans up the bare-minimum state safely. periodt. 💅

lowkey the whole point is the "minimal" part — the state has nothing fancy hanging off it, and the teardown still has to behave. that's the vibe check this test is running. ✨

🌈 SEE ALSO 🌈
