STRUCT PDS_FWCTL_IDENT_CMD(9)

🎀 struct pds_fwctl_ident_cmd(9) 🎀

okay so bestie, welcome to the Kernel API Manual page for struct pds_fwctl_ident_cmd — it's the ✨ Firmware control identification command structure ✨ and honestly it's giving "small struct, big job" energy. Let's get into it 💅

---

✨ SYNOPSIS ✨

like literally, here's the whole shape of it, no cap:

struct pds_fwctl_ident_cmd {
    u8 opcode;
    u8 rsvd;
    u8 version;
    u8 rsvd2;
    __le32 len;
    __le64 ident_pa;
 };

---

🌸 Members 🌸

okay so each field is a whole little moment, let's go one by one, fr fr:

• opcode — the operation code for the command. it's literally telling you what this command even is 🫶
• rsvd — reserved. bestie, do not touch, do not write, it's not for you 🙈
• version — the interface version ✨ (yes it gets its own field, main character energy)
• rsvd2 — also reserved. yes there are two of them. it's a whole thing 💀 leave it alone
• len — length of the identification data 📏
• ident_pa — physical address of the identification data 🔥 (physical, okay? not virtual. we said what we said)

okay real talk, the only "caveat" this page gives you is inline: rsvd and rsvd2 are reserved — so don't be cute, don't fill them in, just leave them be 🙈 and remember ident_pa is a physical address, not a virtual one.

and that's the page bestie!! wrapping it up with the little sign-off from the footer: this one lives under ./include/linux/pds, it's dated October 2026, and it's filed in the Kernel API Manual alongside its page-name twin struct pds_fwctl_ident_cmd(9). drink water, mind your reserved fields, mwah 😭💜🍓
