📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

Okay so this page is ufshcd_query_attr_retry(9) from the Kernel API Manual — and it's literally the API function for sending query attribute with retries. That's the whole vibe, bestie ✨

💖 SYNOPSIS 💖

She rolls in like this:

int ufshcd_query_attr_retry (struct ufs_hba *hba , enum query_opcode
       opcode , enum attr_idn idn , u8 index , u8 selector , u32 *attr_val );

🎀 ARGUMENTS 🎀

  • hba — per-adapter instance 🫶
  • opcode — attribute opcode ✨
  • idn — attribute idn to access 👀
  • index — index field 📇
  • selector — selector field 🎯
  • attr_val — the attribute value after the query request completes 💅

✨ RETURN ✨

Here's the vibe check on what you get back:

  • 0 — upon success ✅
  • > 0 — in case the UFS device reported an OCS error 😭
  • < 0 — if another error occurred 💀
