dc_process_...d_int_enable(9)

💅 dc_process_dmub_dpia_hpd_int_enable(9) — like, the whole glow-up

okay bestie so this is a page from the Kernel API Manual and it's about one (1) little function that pokes the DMUB. yes THAT dmub. sit down, hydrate, let's go 🫶

---

✨ NAME ✨

dc_process_dmub_dpia_hpd_int_enable — submits DPIA DPD interruption 💅 (that's the whole job, she's a specialist)

---

🌸 SYNOPSIS 🌸

void dc_process_dmub_dpia_hpd_int_enable (const struct dc *dc , uint32_t
hpd_int_enable );

that's it. that's the whole signature. no return value, no drama — she's void, she does the thing and she leaves. very demure 🎀

---

🦋 ARGUMENTS 🦋

• dc — [in] the dc structure. yeah. THE dc structure. you know the one ⭐
• hpd_int_enable — [in] a uint32_t that is literally just a yes/no in a trench coat: 1 for hpd int enable, 0 to disable. iconic binary behaviour, no notes 🔥

---

👑 DESCRIPTION 👑

so what she actually does: submits the dpia hpd int enable command to dmub via inbox message 💌

that's the entire description. it's giving "one-line queen." she takes your 1 or your 0, packages up the dpia hpd int enable command, and drops it into dmub's inbox like a text you've been drafting for three hours. bye. periodt 💅✨

like, that's the whole group chat and you ARE gonna read the source file first, iykyk 📖💜

⚠️ real talk though bestie: this is a kernel manpage, so if you're poking at dmub inbox messages on actual hardware, know what you're doing before you 1 something that should be 0. no cap. 🙈

🌸 ok that's the page!! source path lives at ./drivers/gpu/drm/amd/display/... and the date on this baby is October 2026, so yeah — written from the future, still serving facts. mwah, go read dc.c 💖✨🎀
