kunit_register_params_array(9)

📦 version 7.3.1, in nixpkgs unstable

💅 kunit_register_params_array — a Kernel API Manual moment 🎀

okay so bestie, welcome to the kunit_register_params_array(9) page, and yes it's the Kernel API Manual, we're doing kernel API today, get comfy ✨

🌸 NAME 🌸

kunit_register_params_array — registers a parameter array for a KUnit test, that's the whole vibe 💖

✨ SYNOPSIS ✨

kunit_register_params_array (test , array , param_count , get_desc );

like that's literally the whole call, no cap 🫶

🦋 ARGUMENTS 🦋

  • test — the KUnit test structure that the parameters are getting added to. she's the main character, everything goes in her 💅
  • array — an array of test parameters. yes bestie, an actual array of them 😭
  • param_count — number of parameters. the count. the amount. how many 🍓
  • get_desc — a function that generates a string description for a given parameter element. it's giving "make it readable" energy ✨

👑 DESCRIPTION 👑

so this macro initializes the test's parameter array data 🧚 it stores info including the parameter array, its count, the element size, and the parameter description function — all nestled inside test->params_array. iconic behavior, honestly 🌈

💀 NOTE 💀

real talk though: if you're using this macro inside param_init, then kunit_array_gen_params will need to be manually provided as the parameter generator function to KUNIT_CASE_PARAM_WITH_INIT. kunit_array_gen_params is a KUnit function that uses the registered array to generate parameters. don't forget her, she's important 🙈

⭐ SEE ALSO ⭐

Kernel file ./include/kunit/test.h — and the whole extended friend group, all of them, every single one, no skipping 🔥

and that's the page bestie 🫶 shoutout to the ./include/kunit source and the October 2026 date stamp, they ate that fr fr 💖✨🎀
