💖 qed_read_regs(9) 💖

okay bestie, welcome to the Kernel API Manual corner — this is the whole tea on qed_read_regs(9). It’s giving “reads registers into a buffer (using GRC)” and honestly? iconic. 🦋

---

✨ NAME ✨

qed_read_regs — Reads registers into a buffer (using GRC). No cap, that’s the main character energy right there. 💅

---

🌸 SYNOPSIS 🌸

void qed_read_regs (struct qed_hwfn *p_hwfn , struct qed_ptt *p_ptt ,
u32 *buf , u32 addr , u32 len );

---

🎀 ARGUMENTS 🎀

• p_hwfn — HW device data. Like, the hardware device’s data, bestie. 🫶
• p_ptt — Ptt window used for writing the registers. Yes, writing — that’s what the page says, don’t come for me. 💀
• buf — Destination buffer. The place your registers are gonna land. 🍓
• addr — Source GRC address in dwords. Keep that unit, iykyk. ✨
• len — Number of registers to read. Literally how many we’re grabbing. 🌈

---

💜 RETURN 💜

Void. No return value, no drama, periodt. 💅

Cute sign-off time: this page came from ./drivers/net/ethernet/qlogic/qed, October 2026. Slay, bye bestie. 🎀💖
