update_logtype(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay bestie, welcome to update_logtype(9) from the Kernel API Manual — this one is literally about sending a KCCB command to trigger FW to update logtype. slay. 💅

✨ SYNOPSIS ✨

int update_logtype (struct pvr_device *pvr_dev , u32 group_mask );

🎀 ARGUMENTS 🎀

  • pvr_dev — the target PowerVR device, aka the main character of this call 🫶
  • group_mask — the new log group mask; it must pass validate_group_mask. no cap, that part matters 💖

🌸 RETURN 🌸

  • 0 if the provided group_mask is the same as the current value — this is a short-circuit evaluation, bestie ✨
  • 0 on success 🎉
  • any error returned by pvr_kccb_send_cmd 😭
  • -EIO if the device is lost 💀
