STRUCT FSL_HV_IOCTL_START(9)

👑 struct fsl_hv_ioctl_start — Kernel API Manual, bestie edition 💅

Okay so we're in the Kernel API Manual today (section 9, iconic behavior) and the main character is struct fsl_hv_ioctl_start. Say hi 👋

---

✨ NAME ✨

struct fsl_hv_ioctl_start — it starts a partition, that's literally it, that's the whole vibe 🎀

---

🦋 SYNOPSIS 🦋

struct fsl_hv_ioctl_start {
    __u32 ret;
    __u32 partition;
    __u32 entry_point;
    __u32 load;
 };

Four __u32 fields, all accounted for, no notes 🌸 (also yes, there's a little space before that closing brace, we keep it exactly as the universe intended, no cap).

---

💖 Members 💖

• ret — the return error code from the hypervisor. It's the receipts of the operation, lowkey the most important field here 😭
• partition — the ID of the partition you're controlling. Gotta know which one you're talking to, duh 🫶
• entry_point — the offset within the guest IMA to start execution. That's where the party begins ⭐
• load — if this is non-zero, the partition's images get reloaded before starting. Fresh start energy, highkey ✨

🌈 Description 🌈

So when does this struct show up? It's used by FSL_HV_IOCTL_PARTITION_START. That's the whole description, bestie, it's giving "short and sweet" and honestly we respect it 💅

Oh also, "IMA" above is literally the original wording, so don't come for me — we keep the facts character for character around here, periodt 👑

🧚 SEE ALSO 🧚

The kernel file ./include/uapi/linux/fsl_hypervisor.h (struct, iykyk) — and its whole friend group fs fr fr:

• struct fsl_hv_ioctl_restart(9)
• struct fsl_hv_ioctl_status(9)
• struct fsl_hv_ioctl_stop(9)
• struct fsl_hv_ioctl_memcpy(9)
• struct fsl_hv_ioctl_doorbell(9)

Like, all of them. Go read them. They're all slaying in their own way 💜

💀 Cute sign-off 💀

And that's the tea, babe 🍓 This little page comes from ./include/uapi/linux, dated October 2026, and the header up top confirming it's all about struct fsl_hv_ioctl_start(9). Now go start that partition and be the main character of your own kernel 🌟💖
