STRUCT I915_TTM_BUDDY_RESOURCE(9)

💅 NAME 💅

okay so this is the struct i915_ttm_buddy_resource(9) page — header-style struct i915_...ddy_resource(9) — straight outta the Kernel API Manual, and it's giving kernel-struct main character energy ✨.

The NAME section is literally just struct i915_ttm_buddy_resource followed by a dash and no summary text. That's it. No cap. 🫶

bestie, the dash is not me forgetting a description — the original page has no description there.

✨ SYNOPSIS ✨

Here's the struct in all its exact, character-for-character glory — don't let the indentation jump-scare you:

       struct i915_ttm_buddy_resource {
           struct ttm_resource base;
           struct list_head blocks;
           unsigned long flags;
           unsigned long used_visible_size;
           struct gpu_buddy *mm;
        };

🧚 Members 🧚

• base — struct ttm_resource base class we extend. It's the base, and yeah, we extend it. 💖
• blocks — the list of struct i915_buddy_block for this resource/allocation. The buddy-block roster, basically. 🎀
• flags — DRM_BUDDY_*_ALLOCATION flags. That's the whole flag vibe check. 🔥
• used_visible_size — How much of this resource, if any, uses the CPU visible portion, in pages. Very demure, very page-counted. 🌸
• mm — the struct i915_buddy_mm for this resource. And yeah, the synopsis literally spells the pointer as struct gpu_buddy *mm; — both versions are in the original page, so I'm keeping both. iykyk. 🙈

🔥 Description 🔥

Extends the struct ttm_resource to manage an address space allocation with one or more struct i915_buddy_block. That's the plot. It's a TTM resource glow-up that handles address space allocation using one or more buddy blocks. Periodt. 💅

xoxo, bestie 💜 — the source/version line is ./drivers/gpu/drm/i915, the date is October 2026, and the footer title/version vibe is struct i915_...ddy_resource(9). Cute. Slay. 🎀✨
