STRUCT DRM_PVR_HWRT_DATA_REF(9)

💖 NAME

struct drm_pvr_hwrt_data_ref — bestie, this is literally just a Reference HWRT data. That's the whole vibe. ✨

(also hi, welcome to the Kernel API Manual section 9, you're gonna do great 🫶)

---

✨ SYNOPSIS

okay so picture this in a code block, no cap, copy it exactly:

struct drm_pvr_hwrt_data_ref {
    __u32 set_handle;
    __u32 data_index;
 };

that's it. two little __u32s. it's giving minimalism, it's giving "I only have two fields but I'm still the main character" 👑

---

🎀 Members

bestie these are the only two things inside, and they both eat 💅

• set_handle — the HWRT data set handle. yes. that's the handle for the set. iconic of it, honestly.
• data_index — the index of the HWRT data inside that data set. like, where it sits in the group. the position. the little coordinate. 📍

---

💅 SEE ALSO

okay so this list is LONG, like genuinely endless, but I promised I'd keep every single one, so here we go — every reference, in order, untouched, because I'm a good friend 🌸

ok that was a LOT of reading but you made it, I'm so proud of you 😭💖 go read a couple of these, hydrate, and remember: set_handle + data_index, that's the whole struct, that's the whole girl.
