dc_print_dm...gnostic_data(9)

💅 dc_print_dmub_diagnostic_data(9) — from the Kernel API Manual, bestie

Okay so we're in the kernel API manual, section 9, and the page is literally called dc_print_dm...gnostic_data(9) because even the title got tired and took a nap. It's giving "long function name, short temper." 🫶

---

✨ NAME ✨

dc_print_dmub_diagnostic_data — the little function whose whole entire job is to print DMUB diagnostic data for debugging. That's it. That's the vibe. It's the "just print it so I can see what's happening" of the display core world. 🔥

---

🌸 SYNOPSIS 🌸

void dc_print_dmub_diagnostic_data (const struct dc *dc );

Look at her. Returns void — so she does not hand you anything back, she just prints and dips. 💅

---

🎀 ARGUMENTS 🎀

• dc — [in] a pointer to the dc structure (a const struct dc *, so she's reading, not touching your stuff, respect). This is the dc structure. Iconic, honestly.

Heads up bestie: that's the whole argument list. One (1) parameter. No flags, no options, no environment variables, no exit statuses, no signals. She's low-maintenance like that. ✨

Like, that's the whole squad right there. Thirty-five little (9) entries plus the overview file, and every single one gets a mention because we do not leave anyone on read here. 🫶

Also lowkey none of these are options or flags — they're cross-references. Don't @ me. 🙈

🧚 the cute little sign-off 🧚

This page lives under ./drivers/gpu/drm/amd/display/..., and the manual's date stamp is October 2026 — yes, she's timestamped in the future, main character energy only. ✨ And the footer repeats the title dc_print_dm...gnostic_data(9), which we are canonically not retyping because the header already spilled that tea. Periodt. 💖
