💅 xe_guc_pc_action_set_param — Kernel API Manual ✨

okay bestie, welcome to the glow-up page for xe_guc_pc_action_set_param(9) — it lives in the Kernel API Manual and it's literally the "set a value on the SLPC param" girlie. she's short, she's sweet, she does exactly one thing and she does it slayfully 🎀

✨ SYNOPSIS ✨

int xe_guc_pc_action_set_param (struct xe_guc_pc *pc , u8 id , u32 value
);

that's it. that's the whole vibe. one call, three args, returns an int. no cap 💅

🌸 ARGUMENTS 🌸

  • pc — the Xe_GuC_PC instance, aka your main character. this is the power-conservation struct you're passing in, and yes she's required 🫶
  • id — the param id (u8), so the function knows which SLPC param you're talking about. pick your fighter wisely ✨
  • value — the value to set (u32). this is the actual number you want to hand over. iconic behavior 💖

🦋 DESCRIPTION 🦋

so here's the tea: this function can be used to set any SLPC param. literally any of them. that's the entire job description, and honestly? respect. it's giving "small function, big responsibilities" 👑

if you ever find yourself needing to poke a value into an SLPC param, this is the doorway. no extra commentary needed, she said what she said 🔥
