STRUCT IPA_MEM_DATA(9)

💖 struct ipa_mem_data (9) — bestie edition 💖

okay so this is a page from the Kernel API Manual, and it's literally all about struct ipa_mem_data — the glow-up blueprint for IPA memory regions ✨ iykyk

---

🌸 NAME 🌸

struct ipa_mem_data — description of IPA memory regions 🫶

---

✨ SYNOPSIS ✨

struct ipa_mem_data {
    u32 local_count;
    const struct ipa_mem *local;
    u32 imem_addr;
    u32 imem_size;
    u32 smem_size;
 };

no cap, that's the whole vibe right there 👑

---

🎀 Members 🎀

• local_count — number of regions defined in the local[] array 💅 like, how many besties are in the group chat
• local — array of IPA-local memory region descriptors 🌈 the actual squad list
• imem_addr — physical address of IPA region within IMEM 📍 where it actually lives
• imem_size — size in bytes of IPA IMEM region 📏 how much room it's taking up
• smem_size — size in bytes of the IPA SMEM region 🍓 same energy, different memory space
