💅 vmw_mksstat_add_ioctl(9) — Kernel API Manual energy ✨

okay so bestie, welcome to the page for vmw_mksstat_add_ioctl(9) in the Kernel API Manual. This is the ioctl-side bestie that creates a single userspace-originating mksGuestStat instance descriptor and registers that descriptor with the hypervisor. no cap 🫶

💖 NAME 💖

vmw_mksstat_add_ioctl — creates a single userspace-originating mksGuestStat instance descriptor and registers that with the hypervisor. periodt 💅

---

✨ SYNOPSIS ✨

int vmw_mksstat_add_ioctl (struct drm_device *dev , void *data , struct
drm_file *file_priv );

---

🎀 ARGUMENTS 🎀

• dev — identifies the drm device. main character device energy fr fr.
• data — pointer to the ioctl argument. literally the payload pointer, bestie 🍓.
• file_priv — identifies the caller; unused. not it being here just for caller ID and then not being used 💀.

---

🌸 DESCRIPTION 🌸

so what it does: creates a hypervisor PFN mapping, containing a single mksGuestStat instance descriptor, and pins the corresponding userspace pages. That’s the whole flex, and it ate ✨.

---

🔥 RETURN 🔥

• Zero on success 🎉
• a negative error code on error 😭
