UNION DMUB_FW_BOOT_STATUS(9)

💅 union dmub_fw_boot_status(9) 💅

Kernel API Manual, but make it group-chat: we’re talking about union dmub_fw_boot_status, and yes, it’s exactly what it sounds like — a little union situation for status bits. Slay. ✨

💖 NAME 💖

union dmub_fw_boot_status — it’s giving Status bit definitions for SCRATCH0, no cap. That’s the whole name, bestie. 🎀

🦋 SYNOPSIS 🦋

Here’s the exact shape, character-for-character, because C does not do vibes:

union dmub_fw_boot_status {
    struct {
      uint32_t dal_fw : 1;
      uint32_t mailbox_rdy : 1;
      uint32_t optimized_init_done : 1;
      uint32_t restore_required : 1;
      uint32_t defer_load : 1;
      uint32_t fams_enabled : 1;
      uint32_t detection_required: 1;
      uint32_t hw_power_init_done: 1;
      uint32_t ono_regions_enabled: 1;
    } bits;
    uint32_t all;
 };

🫶 MEMBERS 🫶

The original page drops a Members heading here and then gives no member list underneath. That’s the whole vibe — heading present, entries not listed. I’m not inventing any extra member docs, fr fr. 🙈

🌈 SEE ALSO 🌈

Okay, this list is long, and every single reference is here — no skipping, no merging, no “oops I lost one” energy. The kernel file reference is ./drivers/gpu/drm/amd/display/dmub/inc/dmub_cmd.h, and then the references go like this:
