💅 intel_uc_fw_get_upload_size(9)

okay so bestie, welcome to the Kernel API Manual — yes, that Kernel API Manual, the one with all the i915 lore — and today's main character is intel_uc_fw_get_upload_size. she's a little function, she's got one job, and honestly? she ate. ✨

---

🦋 NAME

intel_uc_fw_get_upload_size — literally just get the size of the firmware that needs to be uploaded. that's it. that's the whole vibe. 🎀

---

🌸 SYNOPSIS

u32 intel_uc_fw_get_upload_size (struct intel_uc_fw *uc_fw);

not me returning a u32 like it's nothing 😭 iconic behavior fr fr.

---

💖 ARGUMENTS

• uc_fw — the uC firmware. that's microcontroller firmware for anyone keeping score, and she is the one and only parameter. no cap. 🫶

---

✨ DESCRIPTION

so what does she actually do? she gets the size of the firmware and the header that will be uploaded to WOPCM. that's the whole description, bestie — she's the measuring-tape girlie of the uC firmware world and we love her for it. 📏💜

---

👑

🔥 RETURN

she returns the upload firmware size — and if the firmware fetch failed? you get zero. that's the lowkey sad path. 0 means things did not go how we wanted, so vibe check your fetch before you trust that number, iykyk. 💀

💅 reminder bestie: everything above is exactly what the page says — no extra lore, no invented behavior. she returns the size or 0, and that's periodt.
