get_powerpla...e_entry_v1_0(9)

💅 get_powerplay_table_entry_v1_0(9) — kernel API manual, but make it cute ✨

okay so bestie, grab a lil snack because we're diving into the Kernel API Manual and today's main character is get_powerplay_table_entry_v1_0 💖 this one lives way down in ./drivers/gpu/drm/amd/pm/power... and she's serving hardware back-end realness, no cap.

---

🎀 NAME 🎀

get_powerplay_table_entry_v1_0 — literally creates a Power State out of one single entry in the PowerPlay table 🦋 and like, the way that this function gets called by the hardware back-end? iconic. she's not out here doing solo work, she's a team player fr fr.

---

✨ SYNOPSIS ✨

int get_powerplay_table_entry_v1_0 (struct pp_hwmgr *hwmgr , uint32_t
entry_index , struct pp_power_state *power_state , int
(*call_back_func)(struct pp_hwmgr *, void *, struct pp_power_state *,
void *, uint32_t) );

like yes, that's the whole signature, she's long but she's worth it 💅

---

🌸 ARGUMENTS 🌸

• hwmgr — pointer to the hardware manager 🫶 your lil entry point to all the hardware-manager goodness.
• entry_index — the index of the entry we're extracting from the table 🔥 think of it as your spot in the group chat, but for a table.
• power_state — the address of the PowerState instance being created ⭐ this is the baby being born, gently.
• call_back_func — the function you call into to fill the power state 💜 like, "hey bestie, go populate this for me," and the type is:

int (*call_back_func)(struct pp_hwmgr *, void *, struct pp_power_state *,
void *, uint32_t)

---

😭 RETURN 😭

-1 if the entry cannot be retrieved 💀 that's it, that's the whole return contract. if it fails, you get -1 and you go hydrate and try again.

ngl, if the entry can't be retrieved you legit just get -1 — no extra lore, no dramatic monologue. that's the vibe check and it passed 🍓

okay that's the whole page, bestie, you ate that 🌈 and for the credits moment: this one's filed under ./drivers/gpu/drm/amd/pm/power... with an October 2026 date, and the page header/footer both say get_powerpla...e_entry_v1_0(9) — yes the title's truncated, she's mysterious like that 💀✨ mwah, go read a manpage, ily 🫶
