qed_mcp_ov_update_eswitch(9)

💅 qed_mcp_ov_update_eswitch 💅

okay bestie, so this one lives in the Kernel API Manual (yes, the whole manual, she's that important) and honestly? it's a little one-function wonder and it ate. 🫶

---

✨ NAME ✨

qed_mcp_ov_update_eswitch — send the eswitch mode over to MFW. literally that's the whole job. iconic behavior, no notes. 👑

---

✨ SYNOPSIS ✨

int qed_mcp_ov_update_eswitch (struct qed_hwfn *p_hwfn , struct qed_ptt
*p_ptt , enum qed_ov_eswitch eswitch );

she takes three args and hands you back an int, and no, we are not skipping any of them, keep reading. 🦋

---

✨ ARGUMENTS ✨

• p_hwfn — the HW device data. this is the hardware's whole personality file, treat her with respect. 💖
• p_ptt — P_ptt. yes, that's the description. the manpage said "P_ptt" and honestly? she's mysterious, she's lowkey serving main character energy, iykyk. 🙈
• eswitch — the eswitch mode. the vibe you're sending. ✨

---

✨ RETURN ✨

an Int — 0 means the operation was successul. (their spelling, not mine, 💀 but we're keeping it fr fr, and also 0 = it worked. that's the important part. 🎀)
