STRUCT ACRN_GP_REGS(9)

💅 struct acrn_gp_regs(9)

okay so bestie, welcome to the Kernel API Manual — yes we're literally in the kernel docs rn and it's giving big-brain energy ✨ This page is all about struct acrn_gp_regs, which is, like, the general registers of a User VM. That's it. That's the vibe. It's a whole struct full of register values and honestly? Iconic. 🎀

✨ SYNOPSIS ✨

bestie here's the whole struct laid out, copy it exactly, no cap:

struct acrn_gp_regs {
    __le64 rax;
    __le64 rcx;
    __le64 rdx;
    __le64 rbx;
    __le64 rsp;
    __le64 rbp;
    __le64 rsi;

    __le64 r13;
    __le64 r14;
    __le64 r15;
 };

🦋 Members 🦋

sixteen members, all besties, all holding a register value. let's go down the list 💖

• rax — Value of register RAX 🔥
• rcx — Value of register RCX 🔥
• rdx — Value of register RDX 🔥
• rbx — Value of register RBX 🔥
• rsp — Value of register RSP 🔥
• rbp — Value of register RBP 🔥
• rsi — Value of register RSI 🔥
• rdi — Value of register RDI 🔥
• r8 — Value of register R8 ⭐
• r9 — Value of register R9 ⭐
• r10 — Value of register R10 ⭐
• r11 — Value of register R11 ⭐
• r12 — Value of register R12 ⭐
• r13 — Value of register R13 ⭐
• r14 — Value of register R14 ⭐
• r15 — Value of register R15 ⭐

like, every single one is just "Value of register X" and honestly the consistency? we love to see it 💅
