set_hw_cap(9)

🎀 set_hw_cap 💅 Kernel API Manual — section 9, bestie ✨

ok so we're in section 9 of the kernel API manual today, and the star of the show is set_hw_cap — say hi 👋

---

🌸 NAME 🌸

set_hw_cap — a Private Function used during initialization. that's it, that's the whole vibe. private. mysterious. only shows up when things are getting set up 🫶

---

✨ SYNOPSIS ✨

void set_hw_cap (struct pp_hwmgr *hwmgr , bool setIt , enum
phm_platform_caps cap );

like, look at her. returns nothing, takes three things, absolute main character energy 👑

---

🦋 ARGUMENTS 🦋

• hwmgr — Pointer to the hardware manager. yeah, the whole hardware manager. she's holding the pointer, no pressure or anything 😭
• setIt — A flag indication if the capability should be set (TRUE) or reset (FALSE). literally just on or off, bestie — TRUE means set it, FALSE means reset it, iykyk 🎀
• cap — Which capability to set/reset. the actual one you're flipping. pick your fighter 💅

ngl the whole function is marked private in the original — it's an init-time thing, so don't go treating it like a public glow-up 💀
