💅 dm_test_ism_commit_event_cursor_transition 💅

Okay bestie, welcome to the Kernel API Manual page for dm_test_ism_commit_event_cursor_transition — yes, the name is a whole mouthful, but she’s iconic and we’re obsessed. This is the cursor begin/end FSM test that does not need DC work to slay. 🦋

🌸 NAME 🌸

• dm_test_ism_commit_event_cursor_transition — cursor begin/end drive FSM without DC work.

✨ SYNOPSIS ✨

void dm_test_ism_commit_event_cursor_transition (struct kunit *test );

🎀 ARGUMENTS 🎀

• test — KUnit test context. That’s the little test-world passport, periodt.

🦋 DESCRIPTION 🦋

So here’s the vibe check: BEGIN_CURSOR_UPDATE then END_CURSOR_UPDATE from FULL_POWER_RUNNING traverse the FULL_POWER_BUSY state. She’s literally just passing through, no cap.

Neither transition reaches the idle-optimization commit path, so no DC hardware access occurs and the FSM returns to FULL_POWER_RUNNING. Translation: no hardware drama, no DC work, just the FSM coming back home to FULL_POWER_RUNNING. ✨
