STRUCT CDNSP_DEVICE_CONTEXT_ARRAY(9)

🌸 STRUCT CDNSP_DEVICE_CONTEXT_ARRAY(9) 🌸

okay so we're in the Kernel API Manual bestie, and this one's a little struct page, short and sweet, and honestly it ate 💅 let's get into it.

---

✨ NAME ✨

struct cdnsp_device_context_array —

and that's it. that's the description. it's giving "mysterious main character who says nothing" 😭 the dash is just sitting there empty, no cap, i'm not gonna make stuff up for you.

---

🦋 SYNOPSIS 🦋

here's the whole vibe, character for character:

struct cdnsp_device_context_array {
    __le64 dev_context_ptrs[CDNSP_DEV_MAX_SLOTS + 1];
    dma_addr_t dma;
 };

like, look at her. two members. dev_context_ptrs is an array of __le64 sized CDNSP_DEV_MAX_SLOTS + 1 (yes, plus one, that extra slot is doing its little thing and we respect it 🫶), and then there's dma, a dma_addr_t. iconic. no notes.

---

🎀 Members 🎀

• dma — the DMA address for the device contexts structure, periodt. that's the only member the page spells out for us, so that's the only one i'm gonna explain, i'm not out here guessing 💀
