STRUCT PANTHOR_HEAP(9)

💖 NAME 💖

okay so this is struct panthor_heap(9), and the manual name is the Kernel API Manual — slay. It's the structure used to manage tiler heap contexts, periodt. Tiler heap context management is literally the whole vibe here. 💅

✨ SYNOPSIS ✨

       struct panthor_heap {
           struct list_head chunks;
           struct mutex lock;
           u32 chunk_size;
           u32 max_chunks;
           u32 target_in_flight;
           u32 chunk_count;
        };

🛠️ Members 🛠️

Bestie, here's every field in the struct — they're all main characters, no skipping:

• chunks — list containing all heap chunks allocated so far. ✨
• lock — lock protecting insertion in the chunks list. 🔒
• chunk_size — size of each chunk. 📏
• max_chunks — maximum number of chunks. 🚧
• target_in_flight — number of in-flight render passes after which we'd let the FW wait for fragment job to finish instead of allocating new chunks. 🌈
• chunk_count — number of heap chunks currently allocated. 🔥
