STRUCT MV_CESA_AHASH_DMA_REQ(9)

💅 struct mv_cesa_ahash_dma_req(9) — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual, and today's main character is struct mv_cesa_ahash_dma_req — literally the DMA hash request struct. that's the whole name. no notes. 🎀

---

✨ NAME ✨

struct mv_cesa_ahash_dma_req — DMA hash request. yes that's it, that's the vibe, short and iconic 💖

---

🌸 SYNOPSIS 🌸

struct mv_cesa_ahash_dma_req {
    u8 *padding;
    dma_addr_t padding_dma;
    u8 *cache;
    dma_addr_t cache_dma;
 };

look at her. four fields, zero drama, all business 🦋

---

🫶 Members 🫶

okay let's meet the fields one by one, no cap:

• padding — the padding buffer. that's the whole description, she's mysterious like that ✨
• padding_dma — the DMA address of the padding buffer. so like, padding's little DMA twin 🌈
• cache_dma — the DMA address of the cache buffer. yeah, the DMA address, of the cache buffer, exactly what it says 🔥

ngl, cache is sitting right there in the struct in the synopsis but the Members list just… doesn't describe it 🙈 not me making up lore — the page doesn't say, so i'm not saying either. iykyk 💀
