STRUCT MIPS_STATIC_SUSPEND_STATE(9)

🌸 STRUCT MIPS_STATIC_SUSPEND_STATE(9) 🌸

okay so bestie, welcome to the Kernel API Manual, section 9 — this is the page for struct mips_static_suspend_state, and honestly? it's giving "tiny but crucial." 💅

---

✨ NAME ✨

struct mips_static_suspend_state — the core saved CPU state that survives across S2R. 🫶

---

🦋 SYNOPSIS 🦋

struct mips_static_suspend_state {
  #ifdef CONFIG_EVA;
    unsigned long segctl[3];
  #endif;
    unsigned long sp;
 };

---

🎀 MEMBERS 🎀

• segctl — the CP0 Segment control registers. literally the segment control vibes, saved for later. ✨
• sp — the stack frame where the GP register context is saved. yep, that's where the context lives. 💖

---

💜 DESCRIPTION 💜

So here's the tea: this structure holds the minimal CPU state that has to be saved in static kernel data so that the rest of the state can actually be restored later. no cap. 🧚

That includes the segmentation configuration when EVA is enabled — and this part is important, bestie — because those registers must be restored before any kmalloc'd memory is referenced, including even the stack pointer itself. 😭 like, the stack pointer. the whole thing. periodt.

and that's the whole page, bestie — slay. 💅
