init_dpm_2_parameters(9)

✨ init_dpm_2_parameters(9) ✨

okay so this is a page from the Kernel API Manual, and honestly? it's giving "private function, do not perceive me" energy 💅 like it's literally labeled a Private Function used during initialization and its whole job is to Initialize TDP limits for DPM2. no cap, that's the entire vibe.

---

🌸 SYNOPSIS 🌸

int init_dpm_2_parameters (struct pp_hwmgr *hwmgr , const
       ATOM_Tonga_POWERPLAYTABLE *powerplay_table );

so it returns an int, takes two pointers, and yes babe the line break in the middle of the signature is part of the original, we don't gatekeep 🫶

🎀 ARGUMENTS 🎀

• hwmgr — bestie this is your Pointer to the hardware manager. it's the main character of the whole hardware situation ✨
• powerplay_table — and this one? Pointer to the PowerPlay Table. iconic name, no notes 💖

first up, the Kernel file where all this lives:

./drivers/gpu/drm/amd/pm/powerplay/hwmgr/process_pptables_v1_0.c

and the friend group (all (9) sections, all invited to the group chat 🫶):

• set_hw_cap(9)
• set_platform_caps(9)
• get_platform_power_management_table(9)
• init_clock_voltage_dependency(9)
• init_over_drive_limits(9)
• init_thermal_controller(9)
• get_tonga_state_array(9)
• get_powerplay_table_entry_v1_0(9)

lowkey a whole squad. if you're reading this page you're probably deep in the AMD powerplay hwmgr files at 2am and honestly? respect 😭🔥

💜 that's the whole page, every single crumb of it, nothing skipped 💜

and fr fr, the footer said this all comes from ./drivers/gpu/drm/amd/pm/power... with an October 2026 date, still calling itself init_dpm_2_parameters(9) — so that's the cute little sign-off, mwah 💋✨ stay hydrated and may your TDP limits always initialize 🎀
