STRUCT PDS_VDPA_SET_FEATURES_CMD(9)

💅 struct pds_vdpa_set_features_cmd ✨

okay so bestie, welcome to the Kernel API Manual 🫶 — this one's a struct page and honestly it's kind of a vibe. It's struct pds_vdpa_set_features_cmd, and it does exactly what it says on the tin: it's the little packet you send to tell the hardware which features are on. no cap, that's the whole plot. let's get into it 💖

---

🌸 NAME 🌸

struct pds_vdpa_set_features_cmd — set hw features. literally the "hey hardware, turn these on" struct 👑

---

🎀 SYNOPSIS 🎀

struct pds_vdpa_set_features_cmd {
    u8 opcode;
    u8 vdpa_index;
    __le16 vf_id;
    __le32 rsvd;
    __le64 features;
 };

look at her. so tidy. so aligned. the word-boundary padding is doing its little job and we love that for her 💅

✨ Members ✨

• opcode — the opcode, and it's PDS_VDPA_CMD_SET_FEATURES 🎯 that's how the hardware knows what kind of command this is.
• vdpa_index — the index for the vdpa subdevice 🔢 which one are we talking to, bestie.
• vf_id — the VF id 🆔
• rsvd — word boundary padding 🧚 it's just there to keep things lined up, no thoughts, head empty, purely structural.
• features — the feature bit mask 🌈 this is the actual payload, the whole point, the main character. every bit is a feature flag.

that's the page bestie, go forth and set those features 🔥 mwah 💋
