dm_test_fil..._bt2020_full(9)

💅 dm_test_fill_color_attr_bt2020_full — from the Kernel API Manual (yes, that manual, the kernel one) ✨

okay so bestie, welcome to the group chat 🫶 today's main character is a KUnit test function out of the AMD display driver test suite, and it's literally named dm_test_fill_color_attr_bt2020_full. yes that's a mouthful, yes she ate, and yes we're gonna walk through her whole card together, no skips. 🎀

🌸 NAME 🌸

dm_test_fill_color_attr_bt2020_full — "Test Fill color attr bt2020 full", which is the official description and honestly it's giving exactly what it says on the tin, ngl.

---

✨ SYNOPSIS ✨

void dm_test_fill_color_attr_bt2020_full (struct kunit *test );

that's it, that's the whole signature 💖 she returns void (no receipts, no return value, nothing to check) and takes exactly one argument. slay.

---

🦋 ARGUMENTS 🦋

• test — "The KUnit test context". that's the KUnit test context, periodt. it's the lil' harness object that KUnit hands over so the test knows what it's doing and where to report. you don't build it yourself, it just arrives. 🙈

👑 SEE ALSO 👑

okay this is the part where the manpage absolutely pops off, because the see-also list is long long. like, 55 entries long. no cap. we're listing every single one, bestie, because the original did and we do not skip. 💅

like… the range. the versatility. bt2020's limited sibling is right there at number 24 and this one is the full variant, iykyk. 🌈

ngl the whole list is here verbatim because the original listed it verbatim, and we don't do "and friends" around here — you get all 55 or you get nothing. 💀
