STRUCT PDS_FWCTL_QUERY_CMD(9)

💅 struct pds_fwctl_query_cmd(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for struct pds_fwctl_query_cmd — literally the little struct that carries your query command over to the firmware control interface. she's small, she's packed, she's iconic. let's get into it 🫶

---

🌸 NAME 🌸

struct pds_fwctl_query_cmd — the firmware control query command structure, no cap 💖

---

✨ SYNOPSIS ✨

here's the whole glow-up, verbatim, do not touch:

struct pds_fwctl_query_cmd {
    u8 opcode;
    u8 entity;
    u8 version;
    u8 rsvd;
    __le32 query_data_buf_len;
    __le64 query_data_buf_pa;
    union {
      __le32 ep;
      __le32 op;
    };
 };

---

💅 Members 💅

• opcode — the operation code for the command. it's giving "what are we doing today" energy 🔥
• entity — the entity type you're querying, and it's an enum pds_fwctl_query_entity bestie, so pick a real one 👑
• version — the version of the query data structure that the driver supports. gotta know which era we're in ⭐
• rsvd — reserved. she's there, she's quiet, she's not for you 🙈
• query_data_buf_len — length of the query data buffer. how much room the vibes need 📏
• query_data_buf_pa — physical address of the query data buffer. physical, not virtual, don't get it twisted 😭
• {unnamed_union} — anonymous union, main character energy, doesn't even need a name 💀
  • ep — endpoint identifier to query — this is the one you use when entity is PDS_FWCTL_RPC_ENDPOINT 🎀
  • op — operation identifier to query — this is the one you use when entity is PDS_FWCTL_RPC_OPERATION 🦋

---

🌈 Description 🌈

okay so this struct is what you use to send a query command to the firmware control interface. that's the whole job. and here's the slay detail: the structure is packed so there's literally no padding between the fields — not one single extra byte, we keep it tight, we keep it cute ✨💜
