SCHED_HW_SUBMISSION (INT)(9)

✨ sched_hw_submission (int) ✨

okay bestie, pull up a chair 🎀 this is sched_hw_submission (int), living its best life in section 9 of the Kernel API Manual. It's a little one, but she's iconic for what she does 👑

💅 DESCRIPTION 💅

So like — this one overrides the max number of HW submissions. That's it. That's the whole vibe.

The default is 2. no cap. two. 🫶

If you were expecting a 40-paragraph epic, not today babes, she's short and she knows it 🌸

🦋 SEE ALSO 🦋

the way this page has one sentence of description and then a full guest list 😭 okay. so the kernel file you wanna peek at first is:

like I said — a whole group chat 💀 but every single one is here, bestie, I counted 🧚

lowkey reminder: that bad_page_threshold line above is written exactly how the page writes it, weird grammar and all — I'm not fixing the source's typos, that's not my job 💅

and that's the whole page, babes 🌈 came from ./drivers/gpu/drm/amd/amdgpu, dated October 2026 — periodt, mwah 💖🎀🦋
