ENUM USB4_MARGIN_SW_ERROR_COUNTER(9)

💅 enum usb4_margin_sw_error_counter(9) — Kernel API Manual 🦋

okay so bestie, welcome to the Kernel API Manual, and lemme tell you about this little enum called enum usb4_margin_sw_error_counter — it's literally the Software margining error counter operation, and it's giving "small but mighty" energy ✨

---

🌸 NAME 🌸

enum usb4_margin_sw_error_counter — Software margining error counter operation 🎀

---

✨ SYNOPSIS ✨

Like, here's the whole vibe, verbatim, no cap:

enum usb4_margin_sw_error_counter {
    USB4_MARGIN_SW_ERROR_COUNTER_NOP ,
    USB4_MARGIN_SW_ERROR_COUNTER_CLEAR ,
    USB4_MARGIN_SW_ERROR_COUNTER_START ,
    USB4_MARGIN_SW_ERROR_COUNTER_STOP

};

🧚 Constants 🧚

Four constants, four moods, all of them iconic 👑

• USB4_MARGIN_SW_ERROR_COUNTER_NOP — No change in counter setup. literally just vibing, touching nothing, main character energy of doing absolutely nothing 🙈
• USB4_MARGIN_SW_ERROR_COUNTER_CLEAR — Set the error counter to 0, enable counter. fresh start bestie, we're resetting the whole thing AND turning it on 💖
• USB4_MARGIN_SW_ERROR_COUNTER_START — Start counter, count from last value. it picks up right where it left off, no resetting, we respect the journey 🫶
• USB4_MARGIN_SW_ERROR_COUNTER_STOP — Stop counter, do not clear value. pause the count but keep the receipts, the number stays 🔥

bestie note: every single one of those is a (9) kernel-API page, so if you're lost in the thunderbolt headers, you're in good company 🫶

k that's the page!! this one lives in ./drivers/thunderbolt, dated October 2026, and the whole thing is filed under enum usb4_m...rror_counter(9) in the Kernel API Manual — slay, go read the source, mwah 💅💖🌸
