STRUCT K3_R5_CORE(9)

🎀 struct k3_r5_core(9) 🎀

okay so bestie, we're in the Kernel API Manual today and the main character is literally struct k3_r5_core — the K3 R5 core structure 💅. yes it's a struct, yes it's iconic, no you cannot skip it.

---

✨ NAME ✨

struct k3_r5_core — the K3 R5 core structure, fr fr 🦋

---

🌸 SYNOPSIS 🌸

struct k3_r5_core {
    struct list_head elem;
    struct device *dev;
    struct k3_rproc *kproc;
    struct k3_r5_cluster *cluster;
    struct k3_rproc_mem *sram;
    int num_sram;
    u32 atcm_enable;
    u32 btcm_enable;
    u32 loczrama;
    bool released_from_reset;
 };

like, look at her. ten fields. main character energy 👑. copy it exact tho, no cap 🫶

💖 Members 💖

every single field, bestie, we're not skipping a one:

• elem — linked list item. literally just the list glue holding her in the chain 🔗
• dev — cached device pointer. cached!! it's saved right there so we don't gotta go looking again ✨
• kproc — the K3 rproc handle that represents this core. that's her representative, her spokesperson 💅
• cluster — cached pointer to the parent cluster structure. yeah she's got a parent, we all do 😭 cached pointer too.
• sram — on-chip SRAM memory regions data. the memory region goss, right on the chip 🍓
• num_sram — number of on-chip SRAM memory regions. it's an int, it counts, it slays 🔥
• atcm_enable — flag to control ATCM enablement. a u32 flag, and it's the boss of ATCM ⭐
• btcm_enable — flag to control BTCM enablement. same vibe, but BTCM 🦋
• loczrama — flag that dictates which TCM sits at device address 0x0. flagship flag, deciding who gets the prime real estate 👑
• released_from_reset — a bool flag that signals when the core is out of reset. she's free, she's out, she's thriving 🌈

ngl, flags everywhere — but like, they all mean something, so be nice to them 🧚
