✨ NAME ✨

geni_se_domain_attach — attach power domains to a GENI SE device. that's it, that's the vibe 🦋

🌸 SYNOPSIS 🌸

int geni_se_domain_attach (struct geni_se *se );

one function, one argument, zero drama. slay.

---

💖 ARGUMENTS 💖

• se — pointer to the geni_se structure representing the GENI SE device 💅 like, this is the whole device bestie, be nice to her.

🧚 DESCRIPTION 🧚

okay so here's what's tea: this function attaches the power domains — and yes, there are two of them, "power" and "perf" — that are required in the SCMI auto-VM environment to the GENI Serial Engine device. periodt. 🔥

and then it initializes se->pd_list with the domains it just attached 🫶 so after this runs, your list is populated and everything is giving organized.

ngl if you're gonna poke at the power domains, read the source file first bestie — ./drivers/soc/qcom/qcom-geni-se.c is right there and it's literally the whole context 🙈

and that's the page!! 🍓 sign-off time: this lil manual lives under ./drivers/soc/qcom, dated October 2026, and the page itself is geni_se_domain_attach(9). mwah, go attach some domains 💋✨🦋
