✨ pvr_dev_query_gpu_info_get(9) ✨

okay so bestie, welcome to the pvr_dev_query_gpu_info_get page from the Kernel API Manual 💅 this one's a lil function that asks your PowerVR device to hand over its GPU info, and honestly it's giving "small but mighty" energy 🎀

---

🌸 NAME 🌸

pvr_dev_query_gpu_info_get — the girl whose entire job is fetching GPU info for you, no cap 💖

---

🦋 SYNOPSIS 🦋

int pvr_dev_query_gpu_info_get (struct pvr_device *pvr_dev , struct
       drm_pvr_ioctl_dev_query_args *args );

---

🎀 ARGUMENTS 🎀

• pvr_dev — the device pointer, aka your main character 🔥
• args — [IN] the device query arguments, and inside them is a pointer to a userspace struct drm_pvr_dev_query_gpu_info. it's giving "the info lives in here" ✨

---

💜 DESCRIPTION 💜

so here's the vibe check: if the query object pointer is NULL, the size field gets updated with the expected size of the query object. that's it, that's the whole thing, and she ate 💅

---

⭐ RETURN ⭐

• 0 on success — or if the size is being requested using a NULL pointer 🫶
• -E2BIG if the indicated length of the allocation is less than what's required to contain the copied data 😭
• -EFAULT if local memory could not be copied to userspace 💀
