💖 struct vsp1_dl_cmd_pool(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for struct vsp1_dl_cmd_pool — yes that's a mouthful, yes it's iconic, and yes we're gonna get through it together 🫶

✨ NAME ✨

struct vsp1_dl_cmd_pool — the Display List commands pool. that's it, that's the vibe 💅

🌈 SYNOPSIS 🌈

struct vsp1_dl_cmd_pool {
    dma_addr_t dma;
    size_t size;
    void *mem;
    struct vsp1_dl_ext_cmd *cmds;
    struct list_head free;
    spinlock_t lock;
    struct vsp1_device *vsp1;
 };

literally just a struct, ngl, but she's got range 💀✨

🎀 Members 🎀

omg okay, member by member, let's go 🧚

• dma — the DMA address of the entries. where the memory lives in DMA-land 💫
• size — the size of the full DMA memory pool, in bytes. yes, full pool, no cap 📏
• mem — the CPU memory pointer for the pool. this is the CPU's side of the story 🧠
• cmds — array of command structures for the pool. plural, she's an array 👑
• free — the free pool entries. the available ones, chillin' 🌸
• lock — protects the free list. do not skip the lock, the free list is not okay with being raced on 😭🔒
• vsp1 — the VSP1 device. the main character of this whole situation fr fr ⭐
