STRUCT DMUB_RB_CMD_ENABLE_DISP_POWER_GATING(9)

💅 struct dmub_rb_cmd_enable_disp_power_gating — NAME ✨

okay so bestie, this page is from the Kernel API Manual, and the star of the show is struct dmub_rb_cmd_enable_disp_power_gating — literally just a Display power command. that's the whole vibe. a struct whose entire job is to say "hey, power gating for the display, please." iconic minimalism. 🎀

---

🌸 SYNOPSIS 🌸

here's the whole shape of it, no cap, copy it exactly:

struct dmub_rb_cmd_enable_disp_power_gating {
    struct dmub_cmd_header header;
    struct dmub_cmd_enable_disp_power_gating_data power_gating;
 };

so it's a two-field struct, periodt:

• header — a struct dmub_cmd_header. every one of these command structs starts with one, iykyk. 💫
• power_gating — a struct dmub_cmd_enable_disp_power_gating_data, which is the actual payload carrying the power-gating data. 🦋

that's it. that's the struct. she's small and she knows what she wants.

🧚 Members 🧚

lowkey the original page doesn't actually list any members under this heading — the section is there, but it's empty. so the members you get are just the two in the SYNOPSIS above: header and power_gating. no extra lore, no hidden fields, don't let anyone tell you otherwise. 🙈

this is the part where the page goes absolutely feral and name-drops the entire header file's cast list. the kernel file in question is ./drivers/gpu/drm/amd/display/dmub/inc/dmub_cmd.h, and honestly, everyone's invited to this party: 🔥
