mucse_mbx_powerup(9)

💖 mucse_mbx_powerup(9) 💖

okay bestie, welcome to the Kernel API Manual — yes this is mucse_mbx_powerup(9), the little function that tells the firmware to wake up and go fast (or chill out and go slow). no cap, it's a whole mood. 🦋

---

✨ NAME ✨

mucse_mbx_powerup — echo fw to powerup 🫶

like, it pings the firmware about power state. that's the vibe.

---

🌸 SYNOPSIS 🌸

int mucse_mbx_powerup (struct mucse_hw *hw , bool is_powerup );

yep, that's the whole signature. int in, int out, two args, iconic. 👑

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. the main character, honestly. your hardware's whole identity lives here. 💅
• is_powerup — true for powerup, false for powerdown. it's giving binary. either you're powering up or you're powering down, no in-between, periodt. ⭐

---

🔥 DESCRIPTION 🔥

so here's the tea, bestie: mucse_mbx_powerup echoes the fw (that's firmware, iykyk) to change the working frequency to normal after it receives true — boom, full speed, main character energy. 💀

and if it receives false? it reduces the working frequency. lowkey nap time for the hardware. 😭

that's literally it, that's the whole behavior. no extra lore, don't @ me. 🌈

---

💜 RETURN 💜

• 0 on success 🎉
• negative errno on failure 🙈

so like, check your return value, bestie. if it's negative, something's not slaying.

• mucse_mbx_get_info(9)
• mucse_mbx_sync_fw(9)
• mucse_mbx_reset_hw(9)

all the siblings, all iconic, all worth a look. 🫶

ngl this page is straight facts with zero drama — the firmware just wants to know if it should be fast or not. treat your is_powerup with respect. 💅

🌸 mwah, that's a wrap! this lil' page came from ./drivers/net/ethernet/mucse/r... (the path got cutely truncated, not my fault 💀) and it's dated October 2026 — so like, future vibes. catch you on the next mucse_mbx_powerup(9), bestie! 🎀✨🦋
