💅 dm_test_per...ingle_stream(9) — from the Kernel API Manual ✨

okay bestie, so this page lives in the Kernel API Manual, and it's about a little function with a big name that basically checks that doing the sync thing with only one stream is… literally nothing. no cap, that's the whole bit. 🎀

✨ NAME ✨

dm_test_per_frame_master_sync_single_stream — test that fewer than two streams is a no-op 🦋

like, if there aren't at least two streams to sync up, nothing should happen. it's giving "nothing to see here, move along." 💅

🌸 SYNOPSIS 🌸

void dm_test_per_frame_master_sync_single_stream (struct kunit *test );

that's it, that's the whole signature. she's a void, she takes one argument, she's not returning anything to you. 🙈

💖 ARGUMENTS 💖

  • test — the KUnit test context. it's the little home base the test runs inside. yes, that's it, that's the entire argument. iconic, honestly. 👑

💜 SEE ALSO 💜

the kernel file this lives in, first of all (iykyk):

./drivers/gpu/drm/amd/display/amdgpu_dm/tests/amdgpu_dm_test.c

and then, bestie, the entire friend group — every single sibling test, no one left out. this is the group chat roster fr fr:

like, fifty-five of them. she brought the whole squad. 💀🔥

ok and one little thing: dm_test_per_frame_master_sync_single_stream is the full name even though the header up top goes all coy and shortens it to dm_test_per...ingle_stream(9). don't let the abbreviation jump you. 🙈

and that's the whole page, bestie — short and sweet, just like this function's whole personality. this cutie came from ./drivers/gpu/drm/amd/display/..., dated October 2026, so go forth and test your no-ops with confidence. slay. 💖✨🌈🫶
