🎀 dm_test_construct_old_payload_empty_list — Kernel API Manual 🎀

okay so bestie, we're in the Kernel API Manual, and this is the page for dm_test_cons...d_empty_list(9) — yes that truncation is literally how it's printed, she's just like that 💅. Anyway. There is a KUnit test, it has no payloads in its list, and it wants to know how the PBN/time-slot math shakes out. Let's get into it 🦋

💖 NAME 💖

dm_test_construct_old_payload_empty_list — Test PBN/time-slot calc, empty list ✨

🌸 SYNOPSIS 🌸

void dm_test_construct_old_payload_empty_list (struct kunit *test );

🦋 ARGUMENTS 🦋

  • test — The KUnit test context 🫶 (this is the whole handbag she's carrying, no cap)

✨ DESCRIPTION ✨

okay so picture this: there are literally no other payloads. Zero. Empty list energy 🙈. Because of that, next_payload_vc_start just… does not move — it stays parked at mgr->next_start_slot. So the allocated time slots work out to time_slots = next_start_slot - vc_start_slot. That's the whole vibe check, and honestly? She ate 🔥

👑 SEE ALSO 👑

The kernel file this whole situation lives in, plus every single sibling test it links to — the way that list is LONG, I'm obsessed 😭:

okay real talk: every one of those references is (9) — kernel API section, iykyk. Don't go looking for section 1 versions of these, they're not the moment 💀

and that's the whole page, bestie 🌈 — this one's sourced from ./drivers/gpu/drm/amd/display/..., dated October 2026, and it lives in the manual as dm_test_cons...d_empty_list(9). periodt 💜🫶🍓
