qed_read_fw_info(9)

📦 version 7.3.1, in nixpkgs unstable

💖 qed_read_fw_info(9) — like, the FW info getter 💖

okay so bestie, welcome to the Kernel API Manual page for qed_read_fw_info — yes that's the (9) section, kernel internals territory, main character energy only 🎀

✨ NAME ✨

qed_read_fw_info — reads FW info from the chip. that's it. that's the whole vibe. 🦋

🌸 SYNOPSIS 🌸

bool qed_read_fw_info (struct qed_hwfn *p_hwfn , struct qed_ptt *p_ptt ,
struct fw_info *fw_info );

like, it returns a bool and takes three things. she's simple, she's iconic 💅

🫶 ARGUMENTS 🫶

  • p_hwfn — the HW device data. the hardware's whole deal, basically 🖥️
  • p_ptt — the Ptt window used for writing the registers. that's your little doorway into the registers ✨
  • fw_info — an (Out) pointer, so the function writes the FW info into it. output param, she writes back, no cap 📝

👑 RETURN 👑

Returns true if the FW info was read successfully from one of the Storms — and false if all the Storms are in reset. like, every single one 😭 if they're all resetting bestie, you get nothing. false. periodt.

🧚 DESCRIPTION 🧚

so the FW info is this bundle of FW-related information ✨ — think the FW version, the FW image (main/L2B/kuku), the FW timestamp, etc. all the good stuff 🍓

and the way it gets read? from the internal RAM of the first Storm that is not in reset. first available Storm, that's the one. the others are literally asleep 💀
