STRUCT PDS_CORE_MATCH_RECORD_DESC_CMD(9)

💅 struct pds_core_match_record_desc_cmd(9) — from the Kernel API Manual, bestie 💖

okay so first things first, this came out of the Kernel API Manual and it's the page for struct pds_core_match_record_desc_cmd — the MATCH_RECORD_DESC command. yes that's a mouthful. we're getting through it together 🫶

---

✨ NAME ✨

struct pds_core_match_record_desc_cmd — the MATCH_RECORD_DESC command. that's it, that's the whole vibe 🌸

---

🌈 SYNOPSIS 🌈

here's the struct, exactly as it lives, no cap:

struct pds_core_match_record_desc_cmd {
    u8 opcode;
    u8 ver;
    __le16 type;
    __le16 size;
    u8 rsvd[2];
 };

look at her. five fields, immaculate energy 👑

---

🎀 Members 🎀

• opcode — it's PDS_CORE_CMD_MATCH_RECORD_DESC, literally the whole point of the struct 💅
• ver — the driver's max supported version of this command. like, how new-school your driver is 🦋
• type — the PLDM Descriptor Identifier Type ✨
• size — the length of the Descriptor Identifier Value 📏
• rsvd — word boundary padding. it's just there keeping things aligned. padding is a main character too 😌

---

🔥 Description 🔥

so the deal is: this command expects to find the Descriptor Identifier Data in cmd_regs->data. that's where the data's at, periodt 🫶

also, the driver should keep the devcmd interface locked while it's preparing and sending this command. lock it down, don't let anyone barge in mid-send, iykyk 🔒✨
