dm_test_even...en_encrypted(9)

📦 version 7.3.1, in nixpkgs unstable

✨ NAME ✨

okay so bestie, welcome to dm_test_event_property_update_enabled_when_encrypted — from the Kernel API Manual, no less 💅 — and the whole entire vibe of this one is: encrypted maps to ENABLED. that's it. that's the page. 🫶

🌸 SYNOPSIS 🌸

like, here's the exact shape of it, fr fr:

void dm_test_event_property_update_enabled_when_encrypted (struct kunit
       *test );

🎀 ARGUMENTS 🎀

  • test — the KUnit test context 💖 (yes, that's the whole argument list, she's low maintenance)

🦋 DESCRIPTION 🦋

okay so picture this: a fully connected display 👑 running TYPE0 content with HDCP1 encryption on top. that combo drives the connected path, and the way hdcp_get_content_protection_from_status reports it? it comes back as DRM_MODE_CONTENT_PROTECTION_ENABLED. iconic behavior, honestly. ✨

and because the test is set up before anything gets messy, the connector state is pre-set to ENABLED — so when drm_hdcp_update_content_protection rolls up, it just... leaves it unchanged. nothing to see here, the vibe is already correct 💀🌸

no cap: the whole point is that the state starts as ENABLED and stays ENABLED — don't go expecting a change, that's literally the test 🎀
