geni_find_protocol_fw(9)

geni_find_protocol_fw(9) 💖

okay bestie, welcome to the Kernel API Manual — this page is literally about locating and validating SE firmware for a protocol, and it’s giving “small function, big firmware energy.” ✨

🌸 NAME 🌸

geni_find_protocol_fw — Locate and validate SE firmware for a protocol. 🫶

✨ SYNOPSIS ✨

struct se_fw_hdr * geni_find_protocol_fw (struct geni_se *se , const
       struct firmware *fw , enum geni_se_protocol_type protocol );

🎀 ARGUMENTS 🎀

• se — Pointer to the serial engine structure. That’s the main character here. 💅
• fw — Pointer to the firmware image. The firmware in question, fr fr. 📦
• protocol — Expected serial engine protocol type. Like, which protocol vibe are we checking for? 🦋

🦋 DESCRIPTION 🦋

okay so here’s the tea: this function identifies the appropriate firmware image or configuration required for a specific communication protocol instance running on a Qualcomm GENI controller. no cap, that’s the whole quest. 🔍

It also validates the firmware size against the hardware PROG_RAM_DEPTH read from SE_HW_PARAM_2. so yes, it’s doing a little size vibe check against the hardware info — iconic behavior honestly. 🔥

🔥 RETURN 🔥

pointer to a valid struct se_fw_hdr if found, or NULL otherwise. that’s it. periodt. 👑
