dm_mst_test_...ut_mst_state(9)

💖 NAME 💖

Okay bestie, welcome to the Kernel API Manual, section 9 — this page is dm_mst_test_...ut_mst_state(9), and the main-character function is dm_mst_test_sideband_msg_ready_without_mst_state. It’s giving Test ready bit no-op path, no cap. ✨

🌸 SYNOPSIS 🌸

void dm_mst_test_sideband_msg_ready_without_mst_state (struct kunit
*test );

🎀 ARGUMENTS 🎀

• test — the KUnit test context. That’s the whole argument situation, bestie — just the test context. 💅

🦋 DESCRIPTION 🦋

Verify that a DOWN_REP ready bit is filtered and then ignored when the MST topology manager is not enabled. That’s the vibe check: ready bit gets filtered, then ignored, because the MST topology manager is not enabled. 🔥

🔥 SEE ALSO 🔥
