lpfc_debugfs_disc_trc(9)

💖 NAME 💖

lpfc_debugfs_disc_trc(9) — straight from the Kernel API Manual — is literally the function for Store discovery trace log ✨

okay bestie, let’s get into it 🫶

---

🦋 SYNOPSIS 🦋

the signature is giving:

void lpfc_debugfs_disc_trc (struct lpfc_vport *vport , int mask , char
       *fmt , uint32_t data1 , uint32_t data2 , uint32_t data3 );

---

🎀 ARGUMENTS 🎀

listen, every parameter matters:

• vport — the vport to associate this trace string with for retrieval 💖
• mask — log entry classification, iykyk 🏷️
• fmt — format string to be displayed when dumping the log ✨
• data1 — 1st data parameter to be applied to fmt 🍓
• data2 — 2nd data parameter to be applied to fmt 🍓
• data3 — 3rd data parameter to be applied to fmt 🍓

---

🌸 DESCRIPTION 🌸

okay so this routine is used by the driver code to add a debugfs log entry to the discovery trace buffer associated with vport 💅

Only entries with a mask that match the current debugfs discovery mask will be saved. Entries that do not match will be thrown away — literally not invited to the function 😭

When the log is displayed, fmt, data1, data2, and data3 are used like printf 🫶
