dm_test_han...rq_link_loss(9)

📦 version 7.3.1, in nixpkgs unstable

okay so this is from the Kernel API Manual, and bestie, we're about to read a whole kernel-doc page together like it's the group chat 💅 don't worry, i'll hold your hand through it.

✨ NAME ✨

dm_test_handle_hpd_rx_irq_link_loss — the test that walks the HPDRX link-loss path, no cap 🎀

🦋 SYNOPSIS 🦋

void dm_test_handle_hpd_rx_irq_link_loss (struct kunit *test );

💖 ARGUMENTS 💖

  • test — the KUnit test context. that's it, that's the whole parameter 🫶

🔥 DESCRIPTION 🔥

okay so picture this: HPD RX IRQs are allowed ✅, and a link loss gets reported — and like, no message-ready bits at all 😭.

When that happens, the handler must take the link-loss branch. then it marks is_handling_link_loss and schedules offload work. that's the whole vibe check, and this test is making sure the handler passes it fr fr 💅

lowkey important: this is a test, so it's literally here to make sure the handler does the thing — the branch taken, the flag set, the work scheduled. all three, no skipping 🔥

🌈 SEE ALSO 🌈

okay bestie, buckle up, because this list is long — it's giving "the whole test file said hi" 💀 and there's also a kernel file in here, right at the top of the list:

and that's the whole page, bestie, you ate that 🍓 one last thing: this was served fresh from ./drivers/gpu/drm/amd/display/..., dated October 2026 — so like, future vibes only 👑✨ bye ily 🫶
