dm_test_s3_...i_cec_resume(9)

📦 version 7.3.1, in nixpkgs unstable

💅 NAME

dm_test_s3_handle_hdmi_cec_resume — bestie, this one tests the resume pass over connectors. That's it, that's the whole job. ✨

(This page lives in the Kernel API Manual, and its header is technically dm_test_s3_...i_cec_resume(9) because even manpage titles get the truncation treatment sometimes 😭 — but the real function name is the long one up there, no cap.)

🦋 SYNOPSIS

void dm_test_s3_handle_hdmi_cec_resume (struct kunit *test );

🌸 ARGUMENTS

  • test — the KUnit test context. That's the little test-world it gets handed to do its thing in. 🎀

🔥 DESCRIPTION

Okay so picture this: resume comes through and iterates all connectors, right? It skips the writeback ones (not invited to the party 🚫) and then calls the set path on all the rest of them.

And with NULL notifiers? It's a crash-free no-op. Literally nothing happens, and nothing explodes. It's giving "showed up, did zero work, caused zero problems" — honestly iconic behavior. 👑

💜 SEE ALSO

Buckle up bestie, this list is long — like, scroll-for-a-while long. Every single one of these is a sibling test in the family. 🫶

First up, the kernel file it all lives in:

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

And now the whole crew, in order:

Bestie real talk: dm_test_s3_handle_hdmi_cec_suspend(9) is literally the sibling of this page — the suspend to this resume — so go say hi to it. 🙈

Okay that's a wrap! Sending you off with the lil' sign-off: this page's source line is ./drivers/gpu/drm/amd/display/..., it's the October 2026 version, and it answers to the name dm_test_s3_...i_cec_resume(9) in the footer. Slay, go test some connectors. 💖✨🎀
