STRUCT PDS_CORE_DEV_INFO_REGS(9)

💖 NAME 💖

so this is struct pds_core_dev_info_regs — the device info register format, and it's read-only bestie, you're just looking, not touching ✨

fr fr this is from the Kernel API Manual, section 9, and the page is literally titled struct pds_...ev_info_regs(9) — yes the name is truncated in the header, iconic behavior honestly 💅

🌸 SYNOPSIS 🌸

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

struct pds_core_dev_info_regs {
  #define PDS_CORE_DEVINFO_FWVERS_BUFLEN 32;
  #define PDS_CORE_DEVINFO_SERIAL_BUFLEN 32;
    u32 signature;
    u8 version;
    u8 asic_type;
    u8 asic_rev;
  #define PDS_CORE_FW_STS_F_STOPPED       0x00;
  #define PDS_CORE_FW_STS_F_RUNNING       0x01;
  #define PDS_CORE_FW_STS_F_GENERATION    0xF0;
    u8 fw_status;
    __le32 fw_heartbeat;
    char fw_version[PDS_CORE_DEVINFO_FWVERS_BUFLEN];
    char serial_num[PDS_CORE_DEVINFO_SERIAL_BUFLEN];
    u8 oprom_regs[32];
    u8 rsvd_pad1024[916];
    struct pds_core_dev_hwstamp_regs hwstamp;
    u8 rsvd_pad2048[1016];
 };

👑 Members 👑

okay let's go through the whole cast of characters one by one, no skipping 🫶

• signature — the signature value, and it's 0x44455649 — which is 'DEVI' if you read it as characters 💀 cute little easter egg fr
• version — current version of the info
• asic_type — the Asic type
• asic_rev — the Asic revision
• fw_status — the firmware status flags, and this one's got layers:
  • bit 0 → 1 = fw running
  • bits 4-7 → the 4 bit generation number, which changes on fw restart ✨
• fw_heartbeat — firmware heartbeat counter 🫶 (it's counting, it's alive)
• fw_version — firmware version
• serial_num — serial number
• oprom_regs — oprom_regs to store oprom debug enable/disable and bmp
• rsvd_pad1024 — struct padding (filler, it's giving background character energy)
• hwstamp — hardware current timestamp registers 🎀
• rsvd_pad2048 — struct padding again, we love a consistent king

it lives in the kernel file ./include/linux/pds/pds_core_if.h, and here is the entire friend group, like the whole group chat, nobody gets left out 💜

and that's the whole page bestie, you ate that 💅✨

cute little sign-off: this one comes from ./include/linux/pds, dated October 2026, and the footer's still repping struct pds_...ev_info_regs(9) like the main character it is 👑🌸
