ENUM CVMX_USB_DIRECTION(9)

💅 enum cvmx_usb_direction(9)

okay so real talk, this is a page straight out of the Kernel API Manual — yes, that one — and it's about enum cvmx_usb_direction, which is literally just... the transfer directions. Two of them. That's the whole vibe. Let's get into it bestie 🎀

---

✨ NAME ✨

enum cvmx_usb_direction — the transfer directions 🦋

Like, the directions a USB transfer can go. Both of them. It's giving "short but iconic."

---

🌸 SYNOPSIS 🌸

enum cvmx_usb_direction {
    CVMX_USB_DIRECTION_OUT ,
    CVMX_USB_DIRECTION_IN

};

look at her. two constants, zero drama, all main character energy 👑

---

⭐ Constants ⭐

• CVMX_USB_DIRECTION_OUT — data is transferring from Octeon to the device/host. so it's leaving Octeon, out into the world 🕊️ bye bestie, have fun out there
• CVMX_USB_DIRECTION_IN — data is transferring from the device/host to Octeon. and this one's the opposite: it's coming in, the device/host is sending stuff back to Octeon 🫶 welcome home

ngl the naming is lowkey perfect — OUT goes out, IN comes in. no notes. ate. 💅
