lpfc_idiag_ctlacc_read_reg(9)

✨ lpfc_idiag_ctlacc_read_reg ✨

okay so bestie, welcome to the Kernel API Manual — this is the lpfc_idiag_ctlacc_read_reg(9) page and it's genuinely iconic for such a tiny function 💅

---

🎀 NAME 🎀

lpfc_idiag_ctlacc_read_reg — idiag debugfs read a control registers 🦋

---

🌸 SYNOPSIS 🌸

int lpfc_idiag_ctlacc_read_reg (struct lpfc_hba *phba , char *pbuffer ,
       int len , uint32_t ctlregid );

---

💖 ARGUMENTS 💖

• phba — the pointer to hba structure. that's the whole context bestie, everything hangs off this 🫶
• pbuffer — the pointer to the buffer to copy the data to. it's the destination, the moment, the main character ✨
• len — the length of bytes to copied. yes the original says "to copied" and we respect the original, no cap 😭
• ctlregid — the id to doorbell registers 🔔

---

⭐ DESCRIPTION ⭐

lowkey the whole vibe: this routine reads a control register and copies its content to the user buffer pointed to by pbuffer. that's it, that's the function, and it ate 💅

---

🦋 RETURN 🦋

This function returns the amount of data that was copied into pbuffer. so like, check the return value, it's telling you how much actually landed 🙈
