ENUM DRM_PVR_HEAP_ID(9)

💅 enum drm_pvr_heap_id(9)

okay bestie, welcome to the enum drm_pvr_heap_id(9) page from the Kernel API Manual — yes that's the manual name, we're being official today ✨

This one's short but she's important, so pay attention 🫶

---

🌸 NAME

enum drm_pvr_heap_id — the array index you use for the heap info data that %DRM_PVR_DEV_QUERY_HEAP_INFO_GET hands back to you 💖

---

✨ SYNOPSIS

enum drm_pvr_heap_id {
    DRM_PVR_HEAP_GENERAL ,
    DRM_PVR_HEAP_PDS_CODE_DATA ,
    DRM_PVR_HEAP_USC_CODE ,
    DRM_PVR_HEAP_RGNHDR ,
    DRM_PVR_HEAP_VIS_TEST ,
    DRM_PVR_HEAP_TRANSFER_FRAG ,
    DRM_PVR_HEAP_COUNT

};

🎀 Constants

• DRM_PVR_HEAP_GENERAL — the general purpose heap, your everyday icon 👑
• DRM_PVR_HEAP_PDS_CODE_DATA — the PDS code and data heap, doing code and data things, multitasking queen 💅
• DRM_PVR_HEAP_USC_CODE — the USC code heap 🧚
• DRM_PVR_HEAP_RGNHDR — the region header heap. heads up: only used if the GPU has BRN63142 🫡
• DRM_PVR_HEAP_VIS_TEST — the visibility test heap, iykyk 🔍
• DRM_PVR_HEAP_TRANSFER_FRAG — the transfer fragment heap 🌈
• DRM_PVR_HEAP_COUNT — literally the number of heaps that DRM_PVR_DEV_QUERY_HEAP_INFO_GET returns. and because more heaps may get added later, this also doubles as the copy limit when the caller sends it 📏 no cap

---

🔥 Description

so here's the vibe: for compatibility reasons, all the indices are gonna be present in the returned array — but some heaps may not actually be present, bestie 😭 those ones are indicated where struct drm_pvr_heap.size is set to zero 💀

that's the whole page, bestie — go read the source at ./include/uapi/drm and slay 💅✨

okay so that's a wrap! this came from ./include/uapi/drm and is dated October 2026 — citing my sources like a good student 🎀 bye pookie 🦋💖
