💅 __ufshcd_send_uic_cmd(9) — the Kernel API Manual glow-up

okay so bestie, we're in the Linux kernel API manual (yes, the (9) section, that's the kernel-internals one, iykyk), and today's main character is __ufshcd_send_uic_cmd. the double underscore is not a typo, it's giving "internal, don't @ me" ✨

🌸 NAME 🌸

__ufshcd_send_uic_cmd — Send UIC commands and retrieve the result 💌

like, it sends the UIC commands and it brings back what happened. a full round trip. an icon. 🎀

🦋 SYNOPSIS 🦋

int __ufshcd_send_uic_cmd (struct ufs_hba *hba , struct uic_command
*uic_cmd );

that's it. that's the whole call. two pointers in, one int out. no cap. 🔥

👑 ARGUMENTS 👑

  • hba — the per adapter instance 💜 literally the UFS host bus adapter you're working with, your one and only.
  • uic_cmd — the UIC command 🌈 the actual command struct you're yeeting at it.

⭐ RETURN ⭐

0 if successful; < 0 upon failure.

so like — zero is the slay outcome 🎉 and anything negative means it did not, in fact, slay 😭. that's the whole vibe check, bestie.
