dm_test_atom...bles_scaling(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay so bestie, this one's called dm_test_atomic_check_lvds_non_native_enables_scaling — and what it does is literally: it tests that non-native LVDS turns on scaling. that's it. that's the whole vibe. ✨

(also hi, you're reading section 9 of the Kernel API Manual, the kernel-api girlies' very own corner of the manual pages 🎀)

🌸 SYNOPSIS 🌸

void dm_test_atomic_check_lvds_non_native_enables_scaling (struct kunit
test );

🦋 ARGUMENTS 🦋

  • test — the KUnit test context, bestie. it's the lil' handle the test framework hands you so the test can actually do its thing 🫶

✨ DESCRIPTION ✨

so picture this: you've got an LVDS connector, right? and its adjusted mode is not the same as the native mode, and on top of that it's currently sitting at RMX_OFF. kind of a whole situation. 💀

on a connector exactly like that, the check goes ahead and enables RMX_ASPECT scaling — and it still returns 0. so: scaling on, return value still zero, everyone's happy. no cap. 🔥

it's giving "the test passed, the vibes are immaculate, the return code is 0." periodt. 👑

✨ SEE ALSO ✨
