xe_pci_live_...ce_gen_param(9)

💅 xe_pci_live_...ce_gen_param(9) — from the Kernel API Manual, bestie 🎀

okay so real talk, this is a page from the Kernel API Manual and it's all about xe_pci_live_device_gen_param, which is genuinely one of those helper functions that makes your life so much easier if you're doing KUnit stuff ✨ no cap.

✨ NAME ✨

xe_pci_live_device_gen_param — literally the helper that iterates over Xe devices so you can use them as KUnit parameters 🦋 (yes, that's its whole job, and it ate 💅)

🌸 SYNOPSIS 🌸

const void * xe_pci_live_device_gen_param (struct kunit *test , const void *prev , char *desc );

🎀 ARGUMENTS 🎀

• test — the test context object, your lil home base for the test run 🫶
• prev — the value that got returned last time around, or NULL if this is the very first iteration (first-time energy, main character moment ⭐)
• desc — the buffer where a parameter name goes 🍓

💖 DESCRIPTION 💖

So what it does is: it iterates over all the available Xe devices on the system, and it uses the device name as the parameter name. That's it, that's the vibe check and it passed ✅

Heads up bestie: this is to be used only as a parameter generator function in KUNIT_CASE_PARAM — like, that's its one job, don't be trying to use it for anything else 😭

🔥 RETURN 🔥

You get a pointer to the next struct xe_device all ready to be used as a parameter 💫 — or NULL if there are no more Xe devices on the system, at which point the iteration is done and you can go touch grass 🌈
