qed_dbg_mcp...ump_buf_size(9)

💖 qed_dbg_mcp_trace_get_dump_buf_size(9) 💖

okay so bestie, this is a Kernel API Manual page, and the header was out here looking like qed_dbg_mcp...ump_buf_size(9) because manpage headers really said “abbreviate her.” The full function name is right up there, and it’s giving “tell me the buffer size for mcp trace results” energy. No cap. 🦋

✨ NAME ✨

qed_dbg_mcp_trace_get_dump_buf_size — Returns the required buffer size for mcp trace results. That’s the whole vibe: it tells you how big the buffer needs to be. 🎀

🌸 SYNOPSIS 🌸

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

🎀 ARGUMENTS 🎀

• p_hwfn — HW device data. Like, the hardware device data, bestie.
• p_ptt — Ptt window used for writing the registers.
• buf_size — (OUT) Required buffer size (in dwords) for mcp trace data. Yes, in dwords — read the label, she’s specific. 💅

💅 RETURN 💅

It returns an error if one of the following holds:

• The version wasn’t set.
• The trace data in MCP scratchpad contain an invalid signature.
• The bundle ID in NVRAM is invalid.
• The trace meta data cannot be found (in NVRAM or image file).

Otherwise, returns ok. Periodt. ✨

mwah 💋 that’s the page! It’s from ./drivers/net/ethernet/qlogic/qed, dated October 2026, and the footer was still out here saying qed_dbg_mcp...ump_buf_size(9). byeee 🎀
