ice_prof_gen_key(9)

💅 ice_prof_gen_key — generate profile ID key ✨

okay so bestie, welcome to the kernel API manual for ice_prof_gen_key, and yes we ARE gonna read the whole thing together, no skipping 🫶 this is the ice driver flex pipe stuff, it's giving "deep magic but make it cute".

---

🎀 NAME

ice_prof_gen_key — generate profile ID key ✨ like literally that's the whole job, it builds you a key 👑

---

🌸 SYNOPSIS

int ice_prof_gen_key (struct ice_hw *hw , enum ice_block blk , u8 ptg ,
u16 vsig , u8 cdid , u16 flags , u8 vl_msk[ICE_TCAM_KEY_VAL_SZ] , u8
dc_msk[ICE_TCAM_KEY_VAL_SZ] , u8 nm_msk[ICE_TCAM_KEY_VAL_SZ] , u8
key[ICE_TCAM_KEY_SZ] );

she takes a whole little friend group of arguments and returns an int, periodt 💜

---

✨ ARGUMENTS ✨

okay so every single one of these matters, don't be skipping:

• hw — pointer to the HW struct 🖥️ like, the actual hardware she's working with, no cap.
• blk — the block in which to write profile ID to 🧱 that's the enum ice_block, it's where the profile ID goes.
• ptg — packet type group (PTG) portion of key 📦 a u8, this chunk of the key is the PTG part.
• vsig — VSIG portion of key 🔥 a u16, this chunk is the VSIG part, iconic.
• cdid — CDID portion of key 💫 a u8, the CDID part of the key, slay.
• flags — flag portion of key 🚩 a u16, yep that's the flags bit.
• vl_msk — valid mask ✅ an array of u8 sized ICE_TCAM_KEY_VAL_SZ.
• dc_msk — don't care mask 🙈 also u8[ICE_TCAM_KEY_VAL_SZ], like she literally does not care bestie.
• nm_msk — never match mask 💀 u8[ICE_TCAM_KEY_VAL_SZ], this one never matches, it's giving boundaries.
• key — output of profile ID key 🎁 u8[ICE_TCAM_KEY_SZ], this is where the generated key lands, the main character of the whole function ngl.
