qcom_pas_init_image(9)

📦 version 7.3.1, in nixpkgs unstable

💅 qcom_pas_init_image(9) — like, the Kernel API Manual, but make it make sense

okay so bestie, welcome to the glow-up era of qcom_pas_init_image 🎀 this lil function lives in the Kernel API Manual and it's genuinely so important — it spins up the peripheral authentication service state machine for a given peripheral, using the metadata. no cap, that's the whole vibe of the NAME section, and we're gonna get into it.

✨ SYNOPSIS ✨

int qcom_pas_init_image (u32 pas_id , const void *metadata , size_t size
, struct qcom_pas_context *ctx );

look at that signature. iconic. it returns an int, take notes 📝

🫶 ARGUMENTS 🫶

okay so here's the cast of characters, and honestly each one is doing the most:

  • pas_id — the peripheral authentication service id. this is your main character identifier for the peripheral, periodt 💅
  • metadata — a pointer to memory containing the ELF header, the program header table, and the optional blob of data used for authenticating the metadata and the rest of the firmware. yes, all of that. it's giving whole-package deal 🔥
  • size — the size of the metadata. lowkey necessary, don't skip it 🍓
  • ctx — optional pas context. optional! so you can absolutely pass it or not, no pressure bestie 🌸

⭐ RETURN ⭐

0 on success. that's it. that's the whole section. and honestly? a little minimalist moment from the manpage, but we respect it 🫶

🦋 DESCRIPTION 🦋

okay so here's the part you actually need to remember, because this is the trap that will absolutely catch you slippin':

Upon successful return, the PAS metadata context (ctx) will be used to track the metadata allocation. and it needs to be released by invoking qcom_pas_metadata_release by the caller.

⚠️ so like — successful return means you now own this cleanup. you call qcom_pas_metadata_release. not the function, not the kernel, you. the caller. please don't forget, or the allocation just sits there and that's not the aesthetic we're going for 💀
