qcomtee_params_to_args(9)

📦 version 7.3.1, in nixpkgs unstable

💅 qcomtee_params_to_args — the manual, but make it make sense 💅

okay so bestie, welcome to section 9 of the kernel API manual, where we're talking about qcomtee_params_to_args — literally the glow-up arc where TEE parameters become QTEE arguments. it's giving transformation era ✨

🎀 NAME 🎀

qcomtee_params_to_args — convert TEE parameters to QTEE arguments. no cap, that's the whole job 🦋

✨ SYNOPSIS ✨

int qcomtee_params_to_args (struct qcomtee_arg *u , struct tee_param
*params , int num_params , struct tee_context *ctx );

that's the whole signature, copy it exactly, don't get creative with it 💅

🫶 ARGUMENTS 🫶

  • u — the QTEE arguments. main character energy, this is the destination of the whole conversion 🌈
  • params — the TEE parameters. the source material, the before photo 📸
  • num_params — number of elements in the parameter array. like, count them. that many 🍓
  • ctx — context in which the conversion should happen. the vibe check container, basically 💜

🔥 DESCRIPTION 🔥

okay so the way that this works: it assumes u has at least num_params + 1 entries — not num_params, bestie, num_params + 1, do not come for me, that's literally what it says 😭 — and it also assumes u has been initialized with QCOMTEE_ARG_TYPE_INV as struct qcomtee_arg.type.

that's a big assumption, ngl. it's not checking for you. it's trusting you. act accordingly 🙈

so like. please have your u set up correctly before you call this, or it's giving undefined chaos 👑

💀 RETURN 💀

  • On success, returns 0 — slay, we ate 💖
  • On failure, returns < 0 — less than zero, so, negative. not the vibe, but it's informative 🌸
