STRUCT DPSECI_CFG(9)

💅 struct dpseci_cfg(9) 💅

Okay bestie, welcome to the struct dpseci_cfg(9) page from the Kernel API Manual — yes, that's the manual name, it's giving kernel-docs royalty, we love her for it. This is the configuration struct for DPSECI, and she's honestly pretty lowkey but every field matters, so let's get into it 🫶

---

✨ NAME ✨

struct dpseci_cfg — the structure that represents the DPSECI configuration. That's it, that's the whole vibe. Main character energy, minimal words 💅

---

🌸 SYNOPSIS 🌸

struct dpseci_cfg {
    u32 options;
    u8 num_tx_queues;
    u8 num_rx_queues;
    u8 priorities[DPSECI_MAX_QUEUE_NUM];
 };

Look at her. Iconic. Four members, zero notes. Copy this exactly, please — no "fixing" the spacing, no renaming anything, we are not doing that today 😭

---

🦋 Members 🦋

• options — literally any combination of these flags: DPSECI_OPT_HAS_CG. That's the one listed, that's the one you get ✨
• num_tx_queues — the num of queues towards the SEC. Sending-side queue count, slay.
• num_rx_queues — the num of queues back from the SEC. Coming back the other way, we love a round trip 💖
• priorities — priorities for the SEC hardware processing 🔥. Each place in the array is the priority of the tx queue towards the SEC. Valid priorities are configured with values 1-8 — so 1 through 8, no cap, that's the range, respect it.

ngl bestie, that array is sized DPSECI_MAX_QUEUE_NUM, and each slot maps to a tx queue's priority — so the index is doing real work here. Priorities outside 1-8 are not the valid ones, mwah 💋

aaaand that's the page bestie, you understood it, you slayed it, periodt 🎀✨

Sign-off szn: this little cutie lives in ./drivers/crypto/caam, and the date on the tin is October 2026. Go forth and configure responsibly 💜🧚‍♀️
