wkup_m3_copy_aux_data(9)

📦 version 7.3.1, in nixpkgs unstable

💅 wkup_m3_copy_aux_data(9) — like, the Kernel API Manual page, bestie ✨

okay so picture this: it's a Kernel API Manual page, it's section 9, and the star of the show is wkup_m3_copy_aux_data 🎀 — a function whose whole personality is copying auxiliary data to a special region of m3 dmem. She's niche. She's iconic. She has a hard limit and she's not sorry about it 💅

the deets from the NAME section, in the original's own words-ish:

  • wkup_m3_copy_aux_data — Copy auxiliary data to special region of m3 dmem
  • @data — pointer to data
  • @sz — size of data to copy (limit 256 bytes) 🫶

🌸 SYNOPSIS 🌸

unsigned long wkup_m3_copy_aux_data (struct wkup_m3_ipc *m3_ipc , const
void *data , int sz );

like literally that's the whole signature, no cap 💖

✨ ARGUMENTS ✨

okay so the original is being super mysterious about these, and we are not going to invent lore that isn't there, so:

  • m3_ipc — -- undescribed -- 🙈 (yes bestie, the manpage literally just says that, we don't know more than it does)
  • data — -- undescribed -- 🙈
  • sz — -- undescribed -- 🙈

not me showing up with three whole arguments and zero explanations 😭 the docs said "figure it out" and left. anyway, the signature above is gospel, keep it exactly as-is ⭐

🦋 DESCRIPTION 🦋

so what does she do? Copies any additional blob of data to the wkup_m3 dmem, to be used by the firmware 🔥 that's it. that's the whole vibe. blob goes in, firmware says thank you, everyone's slaying 💜

🎀 friendly reminder from the NAME section: sz has a limit of 256 bytes. respect the limit, bestie, it's giving strict-but-fair 💅

⭐ SEE ALSO ⭐

✨ cute little sign-off ✨

this masterpiece comes to you from the source/version line ./drivers/soc/ti, dated October 2026 🗓️ — go forth and copy those aux blobs, bestie, and remember: 256 bytes max, periodt 👑💖
