STRUCT PDS_CORE_GET_COMPONENT_INFO_CMD(9)

💅 struct pds_core_get_component_info_cmd(9) 💅

okay so bestie, we're in the Kernel API Manual today and this page is literally all about one struct: struct pds_core_get_component_info_cmd. yes it's a long name. no we're not abbreviating it. it's the GET_COMPONENT_INFO command and it's kind of a baddie ✨

---

🎀 NAME 🎀

struct pds_core_get_component_info_cmd — the GET_COMPONENT_INFO command. that's the whole vibe. that's what it does. 💖

---

✨ SYNOPSIS ✨

here's the struct in all its glory, no cap, copied exactly:

struct pds_core_get_component_info_cmd {
    u8 opcode;
    u8 ver;
    __le16 data_len;
    u8 rsvd[4];
    __le64 data_pa;
 };

look at her. so tidy. so structured. main character energy fr 🫶

🌸 Members 🌸

okay let's meet the cast, one by one, bestie:

• opcode — this one's whole personality is PDS_CORE_CMD_GET_COMPONENT_INFO. that's it. that's the value. it's giving "I know who I am." 👑
• ver — the driver's max supported version of this command. so it's like, "this is the highest version I can handle," and honestly same. 😭
• data_len — length of the data sitting at data_pa. the lil measurement girlie. 📏
• rsvd — word boundary padding. it's just there for the alignment vibes. filler episode but make it iconic. 💀
• data_pa — the DMA address of the data. this is the actual address, bestie. the real one. 🔥

🦋 Description 🦋

so here's the tea: FW populates struct pds_core_component_list_info pointed to by data_pa. that's the whole thing. firmware goes in, fills up that struct at the address in data_pa, and everybody's happy. literally that simple, iykyk 💅
