💖 pvr_fw_init(9) 💖

okay so bestie, welcome to the pvr_fw_init page — it lives in the Kernel API Manual and honestly? it's kind of a big deal. this is the function that literally wakes up the firmware. main character energy fr fr 👑

✨ NAME ✨

pvr_fw_init — Initialise and boot firmware 🚀

✨ SYNOPSIS ✨

int pvr_fw_init (struct pvr_device *pvr_dev );

like, that's it. that's the whole vibe check. one function, one argument, so clean 💅

🌸 ARGUMENTS 🌸

  • pvr_dev — the Target PowerVR device. yep, that's the one you're booting. she's the main character of this whole operation 🫶

🦋 DESCRIPTION 🦋

okay so here's the tea ☕ — when this function completes successfully, the PowerVR device is initialised and ready to use. like, fully awake, firmware booted, ready to slay. no cap. 🔥

that's literally the whole description, she's a woman of few words and honestly? iconic.

⭐ RETURN ⭐

so what does she give you back? depends on the vibe:

  • 0 on success — periodt, we ate 💅
  • -EINVAL on invalid firmware image — the image said "not today" 😭
  • -ENOMEM on out of memory — brain empty, no thoughts 💀
  • -ETIMEDOUT if firmware processor fails to boot or on register poll timeout — she's taking too long, we're waiting, it's giving suspense 🙈
ngl, if you get anything that isn't 0, something is lowkey wrong and you should probably look into it. but that's just, like, the return values telling you that. 👀
