STRUCT SCI_POWER_CONTROL(9)

💅 struct sci_power_control(9) — like, the whole kernel API manual vibe ✨

okay so before we even start — yes bestie, this is a page from the Kernel API Manual, and yes it's about a struct. a real one. buckle up 🎀

---

🌸 NAME 🌸

struct sci_power_control — and honestly? the original page leaves the description blank after that dash, so we're not gonna invent one. no cap, that's just how it is. moving on 💖

---

✨ SYNOPSIS ✨

here's the whole thing, character for character, don't touch:

struct sci_power_control {
    bool timer_started;
    struct sci_timer timer;
    u8 phys_waiting;
    u8 phys_granted_power;
    struct isci_phy *requesters[SCI_MAX_PHYS];
 };

like… look at her. five fields. main character energy fr fr 👑

---

🦋 Members 🦋

the page literally just says "Members" and then doesn't list them individually, so here's the lineup from the synopsis itself, and that's all we're claiming:

• bool timer_started
• struct sci_timer timer
• u8 phys_waiting
• u8 phys_granted_power
• struct isci_phy *requesters[SCI_MAX_PHYS]

that's it. that's the members. no extra lore, i'm not gonna make stuff up 🙈

---

💜 Description 💜

okay so the actual tea: this structure defines the fields for managing power control for direct attached disk devices. that's the whole description, verbatim energy, and it's giving "small struct, big responsibilities" ngl 🔥

so when you see timer_started and timer and phys_waiting and phys_granted_power and that requesters[SCI_MAX_PHYS] array — it's all in service of power control on those direct attached disk devices. slay 💅
