💅 dm_test_mcc...set_null_ctx(9)

okay so bestie, real talk: this is a page straight out of the Kernel API Manual, section 9 — the kernel dev girly corner of the manual universe 🧚✨. The title up top got chopped into dm_test_mcc...set_null_ctx(9) which, like, relatable? abbreviated? but the actual function's full government name is dm_test_mccs_vcp_set_null_ctx and we're about to get into it 💖.

🌸 NAME

dm_test_mccs_vcp_set_null_ctx — the vibe check that proves the code bails out early when the context is NULL 🫶 (officially: "Test early return with NULL context")

✨ SYNOPSIS

void dm_test_mccs_vcp_set_null_ctx (struct kunit *test );

🎀 ARGUMENTS

  • test — the KUnit test context 💅. That's it. That's the whole argument list. It's giving minimalism, it's giving "one parameter and a dream", and honestly? Iconic.

🦋 SEE ALSO

okay so here's the thing — this test is lowkey part of a huge friend group, and you should absolutely meet all of them 👑. First, the kernel file where the whole squad lives:

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

and then the entire group chat, in order, no cap 🫶:

not a single one of those got skipped, bestie — the whole roster is here, 142 deep, and yes this test's own siblings like dm_test_mccs_vcp_set_not_supported(9), dm_test_mccs_vcp_set_null_link(9), dm_test_mccs_vcp_set_i2c_packet(9) and dm_test_mccs_vcp_set_i2c_failure(9) are literally right there in the middle of the list. family reunion energy 🎀

okay that's the whole page, no notes 💖. Source/version situash for the record: it comes from ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — mark your calendars bestie, the future called and it's still testing NULL ctx 🌈⭐. byeee 🦋💜
