✨ dm_test_mst_update_mgr_dealloc_null_ctx(9) ✨

okay bestie, welcome to the Kernel API Manual, section 9 — yes we're deep in the kernel docs, but honestly this one is a whole vibe. it's literally one of those "does it crash?" tests, and the answer is no 💅

🌸 NAME 🌸

dm_test_mst_update_mgr_dealloc_null_ctx — a test that proves the null connector does not crash 🫶

like fr fr, that's the whole job. null connector goes in, no crash comes out. iconic.

🎀 SYNOPSIS 🎀

void dm_test_mst_update_mgr_dealloc_null_ctx (struct kunit *test );

🦋 ARGUMENTS 🦋

  • test — the KUnit test context 💜 that's it. that's the argument. she's lowkey carrying the whole test harness on her shoulders and we respect her.

👑 SEE ALSO 👑

first up, the kernel file where all this magic lives — go look, it's giving source-of-truth energy:

  • Kernel file ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_helpers_test.c

and then, bestie… the entire friend group 😭 like genuinely the whole group chat is here, every one of them:

🫶 quick reminder bestie: if you're reading dm_test_mst_update_mgr_dealloc_null_ctx(9) in the manual, you're reading the docs for a test, not a driver function — so don't go calling it in production code, mkay? it's a KUnit test, it lives in the test file up there, and it takes a struct kunit * because that's how the test framework does. periodt.

and that's the whole page, bestie 💖 this one came out of ./drivers/gpu/drm/amd/display/... in the Kernel API Manual, dated October 2026 — go forth and never crash a null connector, mwah 💅✨🎀
