dm_test_upda...lay_and_link(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to the Kernel API Manual 💖 — today's main-character page is dm_test_update_config_populates_display_and_link(9), and it's lowkey all about the active path fills state. no cap.

🌸 NAME 🌸

dm_test_update_config_populates_display_and_link — active path fills state.

✨ SYNOPSIS ✨

void dm_test_update_config_populates_display_and_link (struct kunit
*test );

🎀 ARGUMENTS 🎀

  • test — the KUnit test context, periodt. it's the little context bestie the test runs inside.

🦋 DESCRIPTION 🦋

okay so picture this: dpms_off is clear, and update_config has to serve main-character energy and do the whole checklist. it must build the display and link from config, reset the connector's encryption_status to HDCP_OFF, register the connector, and reach process_output — which enqueues property_validate. the way that pipeline just lines up? iconic ✨

mod_hdcp_add_display reaches add_display_to_topology, which returns early because the DTM TA is left uninitialized — so no firmware is touched. it's giving "we're not even knocking on firmware's door" 💅
