💅 dm_test_read..._vcp_request(9) — Kernel API Manual, bestie edition 🎀

okay so the full title is literally dm_test_read..._vcp_request(9) and yeah, that's a lot of title — the manual calls itself the Kernel API Manual, which is giving very official. anyway. sit down, grab a boba, we're learning about a KUnit test. 🧋✨

🌸 NAME 🌸

dm_test_read_mccs_caps_i2c_vcp_request — bestie, it's a test. It tests the MCCS VCP request packet. That's it, that's the whole vibe. 💖

✨ SYNOPSIS ✨

void dm_test_read_mccs_caps_i2c_vcp_request (struct kunit *test );

like, one function, one argument, no return value. clean. minimal. iconic. 👑

🦋 ARGUMENTS 🦋

  • test — The KUnit test context. that's the whole entire argument list. she takes one (1) thing and she does her job. 🫶
ngl, the argument descriptions here are short and the point has been made — the manpage gives us exactly one argument and exactly one line about it, and we're not gonna invent more. 💀

🔥 SEE ALSO 🔥

okay so this is the part where the manpage just. goes. off. it's the Kernel file ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_helpers_test.c and then a genuinely enormous list of sibling tests, and I'm gonna give you every single one because we don't skip, we don't summarise, we slay. 🌈

like… she has siblings. an entire extended family of them. and honestly? every one of them ate. 🍓

quick vibe check bestie: this page is short and sweet and that's the whole point — one function, one argument, one file, one very long SEE ALSO. don't go reading things into it that aren't written here. iykyk 💅

and that's the page!! the source/version bit at the bottom is ./drivers/gpu/drm/amd/display/... and it's dated October 2026, so like… future me is still out here testing MCCS VCP request packets. obsessed. 💜🦋✨ bye bestie, go run your KUnit tests 🎀
