STRUCT IPA_MEM(9)

✨ struct ipa_mem — IPA local memory region description ✨

okay bestie so this is a page from the Kernel API Manual, section 9, and it's literally all about struct ipa_mem 🫶 it's a little struct that describes a local memory region on the IPA — yes that IPA, the one in ./drivers/net/ipa 💅 stay with me, it's actually so good.

🌸 NAME 🌸

struct ipa_mem — IPA local memory region description. that's it, that's the vibe 🎀

---

🦋 SYNOPSIS 🦋

here's the whole struct, copy it exactly and don't come for me about the indentation:

struct ipa_mem {
    enum ipa_mem_id id;
    u32 offset;
    u16 size;
    u16 canary_count;
 };

like, look at her. four fields. main character energy 👑

💖 Members 💖

okay so let's meet the members one by one, no skipping, we don't do that here:

• id — the memory region identifier 💫 like, which region is this? now we know.
• offset — the offset in IPA memory space to the base of the region 📍 where it starts, basically.
• size — size in bytes, measured from the base of the region 📏 exact words, bestie.
• canary_count — the Number of 32-bit "canary" values that precede the region 🐤 yes the quotes around "canary" are in the original, that's not me being dramatic, that's just the lore. (okay it's a little me being dramatic. but the quotes are real.)

ngl the canary thing is iconic — 32-bit canaries sitting right there in front of your region like tiny little bodyguards 🐥✨
