qla4xxx_sysf...b_tgt_create(9)

✨ NAME ✨

qla4xxx_sysfs_ddb_tgt_create — bestie, this one literally creates the sysfs entry for a target 💅

This is a Kernel API Manual page, and the star of the show is a function called qla4xxx_sysfs_ddb_tgt_create. Yeah, the name is a whole paragraph, we don't make the rules 🎀

---

💖 SYNOPSIS 💖

okay so here's the signature, copy it exactly, no cap:

int qla4xxx_sysfs_ddb_tgt_create (struct scsi_qla_host *ha , struct dev_db_entry *fw_ddb_entry , uint16_t *idx , int user );

---

🌸 ARGUMENTS 🌸

• ha — pointer to host 🫶
• fw_ddb_entry — flash ddb data ✨
• idx — target index 🎯
• user — if set then this call is made from userland else from kernel 👀

---

🎀 RETURN 🎀

On success it hands you back QLA_SUCCESS. On failure it's a QLA_ERROR, and honestly? 😭 iconic either way.

---

🦋 DESCRIPTION 🦋

So what this baddie does is create separate sysfs entries for the session and connection attributes of the given fw ddb entry 🦋 like it's splitting the vibes into their own lil folders.

And there's a plot twist 👀 — if this gets invoked as a result of a userspace call, then the entry gets marked as nonpersistent using the flash_state field. so yeah, userland called, userland energy, not sticking around in flash. periodt 💅
