qed_dbg_reg_...ump_buf_size(9)

✨ NAME ✨

qed_dbg_reg_fifo_get_dump_buf_size — bestie, this one tells you the buffer size you need for the grc trace fifo results 💅 (and yeah, this is a page from the Kernel API Manual, so we're being ✨official✨ about it)

---

🌸 SYNOPSIS 🌸

enum dbg_status qed_dbg_reg_fifo_get_dump_buf_size (struct qed_hwfn
*p_hwfn , struct qed_ptt *p_ptt , u32 *buf_size );

like… it takes three things and gives you back a enum dbg_status, no cap 🫶

---

🎀 ARGUMENTS 🎀

• p_hwfn — the HW device data. it's the hardware's whole personality, lowkey 🦋
• p_ptt — the Ptt window used for writing the registers. that's its one job and it ate 💅
• buf_size — an (OUT) param, so it gets filled in for you: the required buffer size (in dwords) for reg fifo data. iconic behavior honestly ✨

---

🔥 RETURN 🔥

It errors out if literally any of these hold:

• The version wasn't set 💀

Otherwise? returns ok. slay 🌈

okay that's the whole page, mwah 💖 this little gem lives in ./drivers/net/ethernet/qlogic/qed and the version/date stamp on it says October 2026 — so yeah, future-coded of it. bye bestie, go size those buffers 🎀🦋💜
