STRUCT MV_CESA_DEV_DMA(9)

💖 struct mv_cesa_dev_dma(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes, that manual, the one written by kernel devs who have never once used a single emoji 😭 — and today's main character is the DMA pools struct. let's get into it, no cap.

---

✨ NAME ✨

struct mv_cesa_dev_dma — DMA pools, periodt. that's the whole vibe. it's giving "bucket storage for the crypto driver" 🪣✨

---

🦋 SYNOPSIS 🦋

here's the whole look, exactly as it appears, don't come for me about the indentation:

struct mv_cesa_dev_dma {
    struct dma_pool *tdma_desc_pool;
    struct dma_pool *op_pool;
    struct dma_pool *cache_pool;
    struct dma_pool *padding_pool;
 };

four pools, one struct, zero notes 🎀

🌸 Members 🌸

okay this is the part where we meet the squad one by one, and honestly? each of them is iconic in their own little way 💅

• tdma_desc_pool — the TDMA desc pool. that's it, that's her job. she holds TDMA descriptors, and she does it beautifully 🫶
• op_pool — the crypto operation pool. ops live here. it's lowkey the busiest one ngl 💀
• cache_pool — the data cache pool. and before you ask why, here's the tea: it's used by the hash implementation when the hash request is smaller than the hash block size 🍓 so like, tiny requests get the cache pool treatment, fr fr.
• padding_pool — the padding pool. also a hash-implementation girlie, and she specifically shows up when hardware padding cannot be used 🙈 so when the hardware says "not today," padding pool says "say less, i got you."

👑 Description 👑

okay so the whole point of this struct, the thesis statement if you will:

Structure containing the different DMA pools used by this driver.

that's it!! she's a container!! she contains the different DMA pools used by this driver, and honestly that's more than enough. main character energy without even trying 💜✨

listen. the lore is deep. this is the entire extended universe, all the sibling structs, and yes you're gonna read every single one of them because i said so 🌈 the kernel file lives at ./drivers/crypto/marvell/cesa/cesa.h, and the whole family is right here:
