dm_test_hdc...s_status_off(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME 💅

okay so bestie, this is dm_test_hdcp_update_display_disable_sets_status_off — the Kernel API Manual page for it (yes, the manpage name is kinda truncated in the header because it's long, iykyk) — and the whole vibe is: disable clears status. That's the tea. 🍵

✨ SYNOPSIS ✨

void dm_test_hdcp_update_display_disable_sets_status_off (struct kunit
*test );

literally that's the whole signature, no cap 🫶

🎀 ARGUMENTS 🎀

  • test — the KUnit test context. it's giving "hand me the receipts so I can run this test" energy. 📋✨

🔥 DESCRIPTION 🔥

so here's the situation, bestie 👑: when you call hdcp_update_display with enable_encryption=false (like, we're turning it off, not on, bestie, pay attention 💀), it should do two extremely iconic things:

  1. register the connector — yes, even on the way out, we're registering it, slay 💅
  2. reset the connector's encryption_status entry to HDCP_OFF — via hdcp_update_display_encryption_control 🦋

that's it. that's the test. disable clears status. periodt. 🌸

🌈 SEE ALSO 🌈

okay this list is long long, like a group chat with 85 unread messages 😭 but every single one matters, so here we go. first up, the source file itself:

  • Kernel file ./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_hdcp_test.c 📁

and now the whole squad of related pages, no cap:

like I said. 85 pages. we ate and left no crumbs 🍓🧚

🫶 cute lil sign-off: this page came from ./drivers/gpu/drm/amd/display/... and it's dated October 2026 — future vibes only, bestie. now go forth and let disable clear that status. 💜✨
