dm_test_fil...ler_ycbcr444(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

Okay bestie, gather round — this page is from the Kernel API Manual, section 9, and it's all about dm_test_fill_stream_encoding_from_caller_ycbcr444 — aka the test that checks a caller-selected 444.

Like, the whole personality of this function is: you picked YCbCr444, so the code applies it verbatim. No glow-ups, no edits, no "let me just tweak that for you." Iconic honestly. ✨

🎀 SYNOPSIS 🎀

void dm_test_fill_stream_encoding_from_caller_ycbcr444 (struct kunit
*test );

That's it. That's the whole signature. Short and slay. 🫶

🌸 ARGUMENTS 🌸

  • test — The KUnit test context. This is your little test-world-in-a-box, and the function needs it to know which one it's playing in. Don't lose it, bestie. 🎀

🦋 DESCRIPTION 🦋

A caller-selected YCbCr444 encoding is applied verbatim.

That's the whole plot, no cap. Someone up the call chain picked 444, and this test is checking that the encoding gets filled in exactly as requested — nothing swapped out, nothing "improved," nothing quietly changed behind your back. Respect the caller's choices, periodt. 👑
