STRUCT XE_PAGEMAP(9)

🦋 struct xe_pagemap(9) 🦋

okay bestie, welcome to the Kernel API Manual — this page is all about struct xe_pagemap, and it is literally giving “SVM memory management but make it a whole vibe.” ✨

🌸 NAME 🌸

struct xe_pagemap — manages xe device_private memory for SVM. That is the whole assignment, and she ate. 💅

✨ SYNOPSIS ✨

struct xe_pagemap {
    struct dev_pagemap pagemap;
    struct drm_pagemap dpagemap;
    struct work_struct destroy_work;
    struct drm_pagemap_peer peer;
    resource_size_t hpa_base;
    struct xe_vram_region *vr;
};

🎀 Members 🎀

okay so the members, one by one, no skipping:

• pagemap — the struct dev_pagemap providing the struct pages. literally the page provider, iykyk. 🫶
• dpagemap — the drm_pagemap managing allocation and migration. she's handling the alloc/migrate of it all. 🔥
• destroy_work — handles asnynchronous destruction and caching. yep, that spelling is right there in the original, and we are not fixing it because details matter. 😭
• peer — used for pagemap owner computation. tiny field, big “who owns this” energy. 👑
• hpa_base — the host physical address base for the managemd memory. again: original spelling, preserved, no cap. 💀
• vr — backpointer to the xe_vram region. she points back home. 🎀
