si476x_core..._to_revision(9)

📦 version 7.3.1, in nixpkgs unstable

💅 si476x_core_fwver_to_revision — from the Kernel API Manual, bestie

okay so picture this: it's the <rainbow>Kernel API Manual</rainbow> and today's main character is a little function called si476x_core_fwver_to_revision. yes that's a mouthful. no we're not shortening it. it's iconic and it knows it 🎀

✨ NAME ✨

si476x_core_fwver_to_revision — that's it, that's the name, she's mysterious and gives nothing else away 💅

🌸 SYNOPSIS 🌸

int si476x_core_fwver_to_revision (struct si476x_core *core , int func ,
       int major , int minor1 , int minor2 );

look at her. five args and zero chill. let's break it down 🫶

🦋 ARGUMENTS 🦋

  • core — the core device structure. this is the whole vibe, the main character struct, everything runs through her.
  • func — picks which boot function of the device we're talking about, and the options are listed with a *_ prefix situation:
    • *_BOOTLOADER — Boot loader
    • *_FM_RECEIVER — FM receiver
    • *_AM_RECEIVER — AM receiver
    • *_WB_RECEIVER — Weatherband receiver
  • major — the firmware major number
  • minor1 — the firmware first minor number (yes there are two minors, keep up 💀)
  • minor2 — the firmware second minor number

💖 DESCRIPTION 💖

so what does she actually do? she converts a chip's firmware version number into an offset — and that offset is later gonna be used as the offset in the "vtable" of tuner functions. it's giving "translator between two friend groups." lowkey essential. 🌟

and the tea on return values:

this function returns a positive offset in case of success, and a -1 in case of failure. that's it. no in-between. bestie either slays or she doesn't 😭
