💅 genpd_xlate_onecell(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual page for genpd_xlate_onecell(9) — yes the whole thing is named after the function, iconic, we love a self-titled queen 👑

✨ NAME ✨

genpd_xlate_onecell — the xlate function that uses a single index. that's it, that's the whole vibe 🎀

🌸 SYNOPSIS 🌸

struct generic_pm_domain * genpd_xlate_onecell (const struct
       of_phandle_args *genpdspec , void *data );

look at her. returns a struct generic_pm_domain *, takes two args, no notes. slay 💅

🦋 ARGUMENTS 🦋

  • genpdspec — the OF phandle args that get mapped into a PM domain. literally the "which one tho" of the whole operation 🔍
  • data — the xlate function's private data, and it's a pointer to struct genpd_onecell_data. iykyk 🫶

💖 DESCRIPTION 💖

okay so here's the tea ☕ — this is a generic xlate function, and you'd use it to model the simple PM domain controllers: the ones that have one device tree node but hand out multiple PM domains. main character energy but make it a controller ✨

and how does it pick? a single cell is used as an index into an array of PM domains — that array lives in the genpd_onecell_data struct that you specify when you register the provider. so: one cell in, index out, domain located. no cap, that's the whole magic trick 🎩🐇

🔥 SEE ALSO 🔥

bestie there are so many of these and i'm not skipping a single one, we stan completeness 👑

like i said. all of them. 💀

and that's the page, bestie 🫶 this little love letter lives down in ./drivers/pmdomain, it's stamped October 2026, and it answers to the name genpd_xlate_onecell(9) — go forth and index your one cell, you absolute icon 👑✨
