💅 dm_test_mst_start_top_mgr_boot(9) 🎀

okay so bestie, welcome to the Kernel API Manual ✨ — this little page is the whole personality of dm_test_mst_start_top_mgr_boot, and honestly? she's a mood. sit down, grab a boba, and let me tell you about her 🫶

🌸 NAME 🌸

dm_test_mst_start_top_mgr_boot — Test MST start boot path on a connector-backed link 💖 that's her whole job. her only job. she ate and left no crumbs.

✨ SYNOPSIS ✨

the signature, verbatim, no cap:

void dm_test_mst_start_top_mgr_boot (struct kunit *test );

🎀 ARGUMENTS 🎀

  • test — The KUnit test context 💜 literally just the KUnit test context, bestie. that's the whole thing she needs to do her little test-girl thing.

🦋 DESCRIPTION 🦋

okay so here's the tea 🍵 — she uses the DRM KUnit mock device to back the connector, so the link is a realistic connector-backed link. like, cosplay but make it accurate 💅.

and then? the boot path short-circuits and returns true without touching the MST topology manager. not a single touch. the topology manager is over there living its life, unbothered, un-touched, main character energy ✨. she just says "true" and dips 😭
