firmware_req...owait_nowarn(9)

💖 NAME 💖

okay bestie, this is the Kernel API Manual page for firmware_req...owait_nowarn(9), and the star of the show is firmware_request_nowait_nowarn — it's the async version of request_firmware_nowarn 💫.

---

🎀 SYNOPSIS 🎀

int firmware_request_nowait_nowarn (struct module *module , const char
*name , struct device *device , gfp_t gfp , void *context , void
(*cont)(const struct firmware *fw, void *context) );

That's the whole signature, no cap. 🫶

🦋 ARGUMENTS 🦋

• module — the module requesting the firmware. It's giving "I'm the one who asked" energy.
• name — name of firmware file. Literally the file name, bestie.
• device — device for which firmware is being loaded. This is the device in question.
• gfp — allocation flags. The little flags doing allocation business.
• context — will be passed over to cont, and fw may be NULL if firmware request fails. So yeah, sometimes fw is just not gonna be there 😭.
• cont — function will be called asynchronously when the firmware request is over. It's the callback that shows up after the request wraps up.

🌸 DESCRIPTION 🌸

Similar in function to request_firmware_nowait, but with a very specific vibe: it doesn't print a warning when the firmware file could not be found, and it always sends a uevent to copy the firmware image 🔥.

So when the firmware file ghosts you, it's lowkey not gonna spam a warning, and it always sends that uevent to copy the firmware image. Periodt.
