STRUCT FSL_MC_RESOURCE_POOL(9)

💅 struct fsl_mc_resource_pool(9) 💅

okay so bestie, welcome to the Kernel API Manual — this is the struct fsl_mc_resource_pool(9) page and it's literally the glow-up era of resource pools, no cap 🫶

✨ NAME ✨

struct fsl_mc_resource_pool — a Pool of MC resources of a given type 🎀

Like... it's a pool. For MC resources. Of a given type. That's the whole vibe, she's very self-explanatory and we love that for her 💖

---

🌸 SYNOPSIS 🌸

struct fsl_mc_resource_pool {
    enum fsl_mc_pool_type type;
    int max_count;
    int free_count;
    struct mutex mutex;
    struct list_head free_list;
    struct fsl_mc_bus *mc_bus;
 };

look at her. six members. main character energy, honestly 👑

🦋 Members 🦋

get ready, we're doing a full member-by-member vibe check 🔥

• type — the type of resources in the pool, iykyk 🧚
• max_count — the maximum number of resources in the pool, like the ceiling, the limit, the "you shall not pass" of counts ✨
• free_count — the number of free resources in the pool. yes bestie, we're keeping track 💅
• mutex — a mutex to serialize access to the pool's free list. very demure, very mindful, very thread-safe 🔒
• free_list — the anchor node of the list of free resources in the pool. it's giving "starting point of the friend group" 🫶
• mc_bus — a pointer to the MC bus that owns this resource pool. she belongs to somebody, periodt 💜
