dm_test_crtc...ocates_state(9)

💅 dm_test_crtc_reset_state_allocates_state — a whole vibe

okay so bestie, we're in the Kernel API Manual section 9 today, and the star of the show is dm_test_crtc_reset_state_allocates_state. yes that's a long name. no we're not shortening it. she earned it. 👑

✨ NAME ✨

dm_test_crtc_reset_state_allocates_state — the test that makes sure resetting installs a fresh state 🎀

🌸 SYNOPSIS 🌸

void dm_test_crtc_reset_state_allocates_state(struct kunit *test);

🦋 ARGUMENTS 🦋

• test — the KUnit test context. that's it. that's the whole argument. she's low maintenance 💅

🔥 DESCRIPTION 🔥

So here's the tea, bestie 🫖: when you reset a CRTC and there's literally no existing state — like, none, zero, nada — the reset must allocate a brand-new drm_crtc_state and install it. that's the whole test. that's the assignment. it's giving "out with the old, in with the shiny new state" energy ✨

no existing state in, fresh state out. icon behaviour, honestly. 🙈

ngL bestie, if you read all of those you're genuinely built different 🫶

and that's the page!! it lives over at ./drivers/gpu/drm/amd/display/... in the Kernel API Manual, dated October 2026, and yes she keeps her own name in the corner because she's iconic like that. periodt. 💖🎀✨
