smu_v15_0_8_...enabled_mask(9)

💅 smu_v15_0_8_get_enabled_mask 💅

okay so bestie, welcome to the Kernel API Manual ✨ this one's a lil function page and it's honestly giving "small but mighty" energy, let's get into it 🫶

---

🌸 NAME 🌸

smu_v15_0_8_get_enabled_mask — get enabled SMU features, and yes it's the 128-bit kind 😌 lowkey iconic.

---

✨ SYNOPSIS ✨

int smu_v15_0_8_get_enabled_mask (struct smu_context *smu , struct
       smu_feature_bits *feature_mask );

like, that's the whole signature, no cap 💖

---

🎀 ARGUMENTS 🎀

• smu — the SMU context, bestie. it's literally the main character of this whole thing 👑
• feature_mask — the feature mask structure 🦋 this is where the bits end up living

---

💀 DESCRIPTION 💀

okay so here's the tea 🍓 SMU 15 returns all 128 feature bits in one single message, and it does it via out_args[0..3] — one message, all the bits, slay ✨

but for backward compatibility reasons (iykyk 😭), this function returns only the first 64 bits. the other 64 are just... sitting there. living their truth. not returned. 🙈

ngl if you were expecting all 128, this is your reminder that this function is a lil old-school-friendly and only hands you the first half. periodt 💅

---

🔥 RETURN 🔥

• 0 on success 🎉
• negative errno on failure 💀
