STRUCT OMAP_VFSM_INSTANCE(9)

💖 struct omap_vfsm_instance(9) 💖

okay so this is a page from the Kernel API Manual bestie, and it's all about one lil struct, no cap. buckle up 🎀

---

✨ NAME ✨

struct omap_vfsm_instance — literally the per-voltage manager FSM register/bitfield data. that's it, that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

struct omap_vfsm_instance {
    u32 voltsetup_mask;
    u8 voltsetup_reg;
    u8 voltsetup_off_reg;
 };

like, three fields. small struct, big main character energy 👑

---

💅 Members 💅

• voltsetup_mask — the SETUP_TIME* bitmask, and it lives in the PRM_VOLTSETUP* register. yes the asterisks are part of it, don't come for me 😭
• voltsetup_reg — the register offset of PRM_VOLTSETUP, measured from the PRM base. so like, where it sits relative to base, got it 🫶
• voltsetup_off_reg — same deal but for PRM_VOLTSETUP_OFF, also an offset from the PRM base. two regs, both offsets, both from PRM base, slay ✨

🔥 Description 🔥

okay so the description here is honestly iconic in a chaotic way. it's just:

XXX What about VOLTOFFSET/VOLTCTRL?

that's the entire description. no notes. someone in 2011 left this open question in the kernel and it's still out here asking the real questions fr fr 💀 literally XXX What about VOLTOFFSET/VOLTCTRL? — keep it in mind, that's the whole mystery 🧚
