STRUCT VMW_VALIDATION_BO_NODE(9)

💅 struct vmw_validation_bo_node(9) — buffer object validation metadata, bestie 💅

okay so this is the Kernel API Manual page for struct vmw_validation_bo_node(9), and it's literally all about buffer object validation metadata. slay. 🎀

✨ NAME ✨

struct vmw_validation_bo_node — Buffer object validation metadata.

🦋 SYNOPSIS 🦋

       struct vmw_validation_bo_node {
           struct ttm_validate_buffer base;
           struct vmwgfx_hash_item hash;
           unsigned int coherent_count;
        };

🌸 Members 🌸

• base — Metadata used for TTM reservation- and validation. 🫶
• hash — A hash entry used for the duplicate detection hash table. 🔍
• coherent_count — If switching backup buffers, number of new coherent resources that will have this buffer as a backup buffer. 💫

💖 Description 💖

okay so the vibe here is space conservation, no cap: bit fields are used since these structures are allocated and freed in large numbers and space conservation is desired. every byte is lowkey iconic. 💅✨
