✨ pvr_fw_valid..._device_info ✨

okay bestie so this is a page from the Kernel API Manual, section 9, and the full grown-up name of the function is pvr_fw_validate_init_device_info 💅 yes it's a mouthful, we're gonna get through it together.

🌸 NAME 🌸

pvr_fw_validate_init_device_info — the icon that validates your firmware and sets up your device info in one go ✨ she does both, she's a multitasker, main character energy fr.

🎀 SYNOPSIS 🎀

int pvr_fw_validate_init_device_info (struct pvr_device *pvr_dev );

that's it, that's the whole call, no cap 🫶

🦋 ARGUMENTS 🦋

  • pvr_dev — your target PowerVR device 👑 like, the actual device you're doing all this for. hand her over and let her cook.

💖 DESCRIPTION 💖

so the vibe check here is: this function must be called before you go querying device information. not "should", not "maybe", must — it's giving prerequisite, it's giving "do this first or nothing works" 🙈

literally just call her before you start asking the device questions, and you're slaying 🌈

⭐ RETURN ⭐

  • 0 on success 🎉 iconic, flawless, no notes
  • -EINVAL if firmware validation fails 💀 that's the "nope, firmware didn't pass" exit — validation fell over, so nothing gets initialised.
