dpmcp_open(9)

💅 dpmcp_open(9) — from the Kernel API Manual

okay bestie, gather round, because today we're opening a control session and honestly? it's giving main character energy. this one lives in the Kernel API Manual, section 9, and it's all about handing you a shiny token for one specific object. let's get into it 🫶

---

✨ NAME ✨

dpmcp_open — open a control session for the specified object. that's it, that's the whole vibe. 💫

---

✨ SYNOPSIS ✨

int dpmcp_open (struct fsl_mc_io *mc_io , u32 cmd_flags , int dpmcp_id ,
u16 *token );

literally just call it like that, no cap. 🌸

---

✨ ARGUMENTS ✨

• mc_io — pointer to the MC portal's I/O object. this is your portal bestie, the connection you're rolling through. 🌀
• cmd_flags — command flags; one or more of 'MC_CMD_FLAG_'. yes, one or more, pick from that family, you got this.
• dpmcp_id — the DPMCP unique ID. your object's little ID card. 🪪
• token — the returned token; use it in subsequent API calls. it's the VIP wristband of this whole operation, do not lose it. 🎀

---

✨ DESCRIPTION ✨

so here's the tea ☕ — you know how some functions are out here creating things? this one is not that.

dpmcp_open can be used to open a control session for an object that's already been created. that object might have been declared in the DPL, or it might have been born when someone called the dpmcp_create function. either way, it exists, and now you want a session with it. iconic. 👑

what you get back is a unique authentication token. and this token is associated with two things, very specifically:

• the specific object ID
• the specific MC portal

and here's the part where you must pay attention, bestie 🙈 — that token has to be used in all subsequent commands for this specific object. not some of them. all of them. it's giving loyalty era, no fumbling. 💜

---

✨ RETURN ✨

the original has a RETURN heading sitting there with absolutely nothing under it 😭 — not me staring at a blank section. there is genuinely no return description given here, so we're not gonna invent one. we respect the mystery. 💀

---

✨ SEE ALSO ✨

• Kernel file ./drivers/bus/fsl-mc/dpmcp.c — go read the source, it's right there, iykyk 📖
• dpmcp_close(9) — yes, the counterpart. you open, you close. balance. 🌈

🧚 friendly heads-up: everything above is exactly what the page says and nothing more — no extra lore, no invented behaviour. if it's not in the manpage, it's not in this group chat. 💅

🌸 and that's a wrap! this lil page came to you from the source ./drivers/bus/fsl-mc, dated October 2026, and it's literally titled dpmcp_open(9) — slay, periodt, go open that session bestie ✨🫶
