dm_test_hpd_..._source_hpd4(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay so bestie, welcome to the Kernel API Manual entry for dm_test_hpd_to_dal_irq_source_hpd4(9) — yes, the title is a whole mouthful, they really said "let's put the entire function name in the header" and honestly? slay. The full name up top is dm_test_hpd_..._source_hpd4(9), which is just the long version of the same thing wearing a cute little abbreviation.

This page is literally about:

dm_test_hpd_to_dal_irq_source_hpd4 — Test Hpd to dal irq source hpd4

that's it, that's the whole vibe. it's a test. it tests the HPD → DAL IRQ source mapping for hpd4. no notes, periodt. ✨

🦋 SYNOPSIS 🦋

the whole signature, verbatim, no edits:

void dm_test_hpd_to_dal_irq_source_hpd4 (struct kunit *test );

so she's a void function, she takes exactly one thing, and she gives nothing back. icon behavior. 💅

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. that's the one (1) thing you hand her. she needs it, she uses it, she moves on. ngl very low-maintenance of her. 🫶

🔥 SEE ALSO 🔥

okay this is the part where I have to list everything because I am not about to gatekeep the whole test family from you. it's giving "the entire squad showed up to the group chat" 😭. every single one of these cross-references is listed, no cap, in the original order:

and the kernel file it all lives in, fr fr:

./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_irq_test.c

like I said. the whole squad. 💀

that's the page bestie, hope hpd4 treats you well 🌸 and okay one last cute sign-off — this came from the source/version tree rooted at ./drivers/gpu/drm/amd/display/... and it's dated October 2026, so yeah, she's from the future, main character energy only 👑💜🦋
