STRUCT DRM_PVR_IOCTL_DESTROY_HWRT_DATASET_ARGS(9)

💅 struct drm_pvr_ioctl_destroy_hwrt_dataset_args(9)

okay so bestie, welcome to the glow-up era of this little struct — it lives in the Kernel API Manual, and honestly? it's giving "tiny but mighty." This page is literally about the args struct you hand over when you wanna yeet a hardware ray-tracing dataset into the void. No cap, it's four bytes of business and four bytes of "please behave."

---

✨ NAME ✨

struct drm_pvr_ioctl_destroy_hwrt_dataset_args — these are the arguments for %DRM_IOCTL_PVR_DESTROY_HWRT_DATASET, aka the official paperwork for saying "this HWRT dataset? gone. bye. 🦋"

---

🎀 SYNOPSIS 🎀

struct drm_pvr_ioctl_destroy_hwrt_dataset_args {
    __u32 handle;
    __u32 _padding_4;
 };

look at her. two fields. zero drama. she ate and left no crumbs 💅

---

🌸 Members 🌸

• handle — [IN] the handle for the HWRT dataset that's about to be destroyed. this is your "which one, bestie?" field, and you do need to fill it in, it's an input 🫶
• _padding_4 — reserved. this field must be zeroed. not "should," not "ideally," not "if you feel like it" — zero it. it's reserved for a reason and the kernel is not here for your creative interpretation 😭

fr fr, zero out _padding_4. reserved fields are the quiet kids in the back of the class — leave them alone and everything's chill 💀

okay this is the part where the page just keeps going, and the way I'm obsessed — here's the entire extended universe, every last one, no skips, no cuts, no "you get the idea" 💖

that's the whole page, bestie — nothing skipped, nothing hidden, we keep every single detail in this house 👑

shoutout to the source directory ./include/uapi/drm and the date October 2026 — that's where this page comes from and when it was stamped, and the footer title is struct drm_p...dataset_args(9) in case you were wondering what the little truncated legend at the bottom said. mwah 💋🎀

now go forth, zero your padding, and destroy that dataset with main character energy ⭐
