pvr_power_reset(9)

✨ pvr_power_reset — reset the GPU ✨

Okay so this is pvr_power_reset(9) from the Kernel API Manual, and honestly bestie, it's a whole little drama in one function 💅 Let's get into it.

🎀 SYNOPSIS 🎀

int pvr_power_reset (struct pvr_device *pvr_dev , bool hard_reset );

🌸 ARGUMENTS 🌸

• pvr_dev — Device pointer. That's your GPU's whole deal right there 🫶
• hard_reset — true for a hard reset, false for a soft reset. Pick your fighter 💀

🦋 DESCRIPTION 🦋

Okay so here's the tea: if hard_reset is false and the FW processor fails to respond during the reset process, this function will go ahead and attempt a hard reset anyway. So like, the soft reset has a backup plan built in, no cap ✨

And if a hard reset fails? Then the GPU device is reported as lost 😭 That's the bad ending, fr fr. Like it's giving "we tried everything and the vibes are simply not vibing."

⭐ RETURN ⭐

• 0 on success — slay 👑
• Any error code returned by pvr_power_get, pvr_power_fw_disable or pvr_power_fw_enable. Yeah, it just passes those along, iykyk 💜
