STRUCT SCU_SGPIO_REGISTERS(9)

💅 struct scu_sgpio_registers(9) — from the Kernel API Manual, bestie

okay so picture this: you're deep in the kernel, you open a header file, and this struct is just there, glowing, main character energy ✨. It's called struct scu_sgpio_registers, and yeah — it's literally the SCU SGPIO Registers. That's the whole vibe. No cap.

✨ NAME ✨

struct scu_sgpio_registers — SCU SGPIO Registers 🎀

Like, that's it. That's the name. Short, sweet, slays.

🌸 SYNOPSIS 🌸

Here's the whole thing, character for character, because we do not mess with code around here 👑

struct scu_sgpio_registers {
    u32 interface_control;
    u32 blink_rate;
    u32 start_drive_lower;
    u32 start_drive_upper;
    u32 serial_input_lower;
    u32 serial_input_upper;
    u32 vendor_specific_code;
    u32 reserved_001c;
    u32 output_data_select[8];
    u32 reserved_1444_14ff[0x30];
 };

Look at those field names ngl — interface_control, blink_rate, start_drive_lower, start_drive_upper, serial_input_lower, serial_input_upper, vendor_specific_code, reserved_001c, output_data_select[8], reserved_1444_14ff[0x30]. It's giving "register layout that knows exactly what it is" 💅

🦋 Members 🦋

So here's the thing — this page has a Members section and it is… empty. Crickets. Not a single member documented 😭. The struct spills all those fields in the synopsis and then the Members section just stands there like 🧍

That's not me skipping it, bestie, that's genuinely all it says. The full members list is nothing. Periodt.

🔥 SEE ALSO 🔥

Go touch some related grass, all of it lives in the kernel file ./drivers/scsi/isci/registers.h:

• struct scu_viit_entry(9)
• struct scu_iit_entry(9)
• struct smu_registers(9)
• struct scu_sdma_registers(9)
• struct scu_transport_layer_registers(9)
• struct scu_link_layer_registers(9)
• struct scu_port_task_scheduler_registers(9)

That's twelve little besties and every single one of them is getting linked. iykyk 🌈

Heads up 🫶 this is a kernel API page, so it's talking to people writing kernel code — everything here is literal, so treat the names and types exactly as written. No vibes-based renaming, bestie 💀

⭐ and that's the page! brought to you by ./drivers/scsi/isci, dated October 2026, and stamped struct scu_sgpio_registers(9) at the bottom because it's iconic like that. mwah 💖🧚‍♀️
