STRUCT FIRMWARE_FALLBACK_CONFIG(9)

✨ STRUCT FIRMWARE_FALLBACK_CONFIG(9) ✨

okay bestie, buckle up — this is the struct firmware_fallback_config situation, straight out of the Kernel API Manual, and it's literally just the lil control panel for firmware fallback settings 🎀 no cap, it's giving "tiny struct, big responsibilities."

---

🌸 NAME 🌸

struct firmware_fallback_config — firmware fallback configuration settings. that's it, that's the vibe 💅

---

🦋 SYNOPSIS 🦋

struct firmware_fallback_config {
    unsigned int force_sysfs_fallback;
    unsigned int ignore_sysfs_fallback;
    int old_timeout;
    int loading_timeout;
};

💖 MEMBERS 💖

aww look at these four little icons, let's meet them 🫶

• force_sysfs_fallback — this one forces the sysfs fallback mechanism to be used, literally as if someone had enabled CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y. super useful for helping debug CONFIG_FW_LOADER_USER_HELPER_FALLBACK=y functionality on a kernel where that config entry has been disabled. it's giving "pretend the switch is on" energy ✨
• ignore_sysfs_fallback — the opposite bestie 😭 this one forces the sysfs fallback mechanism to be disabled. it emulates the behaviour as if we had set the kernel config CONFIG_FW_LOADER_USER_HELPER=n. bye bye fallback 💀
• old_timeout — for internal use. that's the whole description, no further comment, mind your business 🙈
• loading_timeout — the timeout to wait for the fallback mechanism before giving up, measured in seconds. the "okay we've waited long enough" clock ⭐

---

🧚 DESCRIPTION 🧚

helps describe and fine tune the fallback mechanism. lowkey does exactly what it says on the tin 💜

and that's the whole page, bestie! 🌈 this masterpiece lives under ./drivers/base/firmware_loader, dated October 2026, and it's filed as struct firm...lback_config(9) — go forth and tune those fallbacks, you absolute icon 👑💖
