STRUCT DEVLINK_FLASH_UPDATE_PARAMS(9)

💅 STRUCT DEVLINK_FLASH_UPDATE_PARAMS(9) 💅

okay so bestie, welcome to the Kernel API Manual entry for struct devlink_flash_update_params — yes that's a mouthful, yes it's iconic, and yes we're gonna get through it together 🫶

This page is literally all about the Flash Update parameters — the little bundle of info that tells the kernel how a firmware flash update should go down. main character energy fr fr ✨

---

✨ SYNOPSIS ✨

struct devlink_flash_update_params {
    const struct firmware *fw;
    const char *component;
    u32 overwrite_mask;
 };

look at her. three members. flawless. no notes 💅

---

🎀 MEMBERS 🎀

• fw — pointer to the firmware data to update from 📦 like, this is the actual firmware payload you're flashing, the whole reason we're here
• component — the flash component to update 🧩 which part of the flash are we touching, bestie
• overwrite_mask — which types of flash update are supported (may be 0) 🎚️ yep, it can absolutely be zero, that's valid, don't panic

---

🌸 DESCRIPTION 🌸

okay so here's the tea ☕ with the exception of fw, drivers must opt-in to parameters by setting the appropriate bit in the supported_flash_update_params field in their devlink_ops structure.

read that again. fw is the freebie — everything else? you gotta opt in, bestie. set that bit, claim your parameter, live your truth 🌈 no bit, no param, periodt 💀
