STRUCT DPSW_ACL_ENTRY_CFG(9)

💜 struct dpsw_acl_entry_cfg(9) — the ACL entry glow-up

okay so bestie, welcome to the Kernel API Manual ✨ this one's a tiny little struct but she's important — she's the ACL entry itself, the actual rule that gets checked. she's from dpsw.h in the freescale dpaa2 driver world, mmmkay? let's get into it 💅

---

✨ NAME ✨

struct dpsw_acl_entry_cfg — an ACL entry. that's it. that's her. one entry in your access control list, living her best life 🎀

---

🦋 SYNOPSIS 🦋

struct dpsw_acl_entry_cfg {
    u64 key_iova;
    struct dpsw_acl_result result;
    int precedence;
 };

look at her. three fields. iconic. not a single wasted line 🌸

👑 Members 👑

• key_iova — this is the I/O virtual address of DMA-able memory, and that memory is filled with your key 🗝️ — but heads up bestie, only after you've called dpsw_acl_prepare_entry_cfg. so don't go reading it before that, okay? order matters, no cap.
• result — a struct dpsw_acl_result, and this is literally the required action to take when this entry gets hit 🔥 like, the entry matched, now what? that's what this field is for.
• precedence — the precedence inside the ACL, and bestie, 0 is the lowest 📉 so if you want something to win, you gotta go higher. BUT — and this is the important part — this priority can not change during the lifetime of a Policy 💀 periodt. it's locked in. and it's your responsibility as the user to space the priorities out according to the consequent rule additions you're planning. so like... plan ahead, okay? give yourself room to insert stuff later 🙈

🫶 fr fr, read that precedence bit twice. a Policy's lifetime is a long time and you can't renumber later. that's a you problem, not a struct problem.
