🎀 qed_get_mcp_...lts_buf_size(9) 🎀

okay bestie, welcome to the Kernel API Manual — this page is all about a tiny-but-iconic helper, and yes it's giving “buffer size math” main character energy. 💅

✨ NAME ✨

qed_get_mcp_trace_results_buf_size — returns the required buffer size for MCP Trace results, in bytes. That's the whole assignment, no cap. 🫶

🌸 SYNOPSIS 🌸

enum dbg_status qed_get_mcp_trace_results_buf_size (struct qed_hwfn *p_hwfn , u32 *dump_buf , u32 num_dumped_dwords , u32 *results_buf_size );

🦋 ARGUMENTS 🦋

• p_hwfn — HW device data. 💖
• dump_buf — MCP Trace dump buffer. 🎀
• num_dumped_dwords — number of dwords that were dumped. Literally the count, bestie. ✨
• results_buf_size — (OUT) required buffer size (in bytes) for the parsed results. 👑

🔥 RETURN 🔥

Error if the parsing fails, ok otherwise. So: parsing goes off? error. Parsing is fine? ok. Periodt. 💀
