STRUCT PDS_CORE_DEV_CMD_REGS(9)

Okay bestie, you're looking at the Kernel API Manual page for struct pds_core_dev_cmd_regs. It's the device command register format, and it is read-write. No cap, this is the whole struct vibe check. ✨

🌸 NAME 🌸

struct pds_core_dev_cmd_regs — Device command register format (read-write).

🦋 SYNOPSIS 🦋

Here's the exact shape, bestie — keep these fields exactly as they are:

struct pds_core_dev_cmd_regs {
    u32 doorbell;
    u32 done;
    union pds_core_dev_cmd  cmd;
    union pds_core_dev_comp comp;
    u8 rsvd[48];
    u32 data[478];
 };

💖 Members 💖

Every field is doing its own main-character thing:

• doorbell — Device Cmd Doorbell, and it's write-only. Write a 1 to signal device to process cmd. 💅
• done — Command completed indicator. Poll for completion — bit 0 == 1 when command is complete. 👀
• cmd — Opcode-specific command bytes.
• comp — Opcode-specific response bytes.
• rsvd — Struct padding (u8 rsvd[48]).
• data — Opcode-specific side-data (u32 data[478]).
