qla2x00_nvram_request(9)

💅 qla2x00_nvram_request — the Kernel API Manual page you didn't know you needed

okay bestie, so this one lives in the Kernel API Manual (yes, section 9, the ~cool~ one) and it's literally called qla2x00_nvram_request. let's get into it ✨

---

🌸 NAME 🌸

qla2x00_nvram_request — Sends read command to NVRAM and gets data from NVRAM. that's the whole vibe, no cap 💖

---

🎀 SYNOPSIS 🎀

uint16_t qla2x00_nvram_request (struct qla_hw_data *ha , uint32_t nv_cmd
);

---

🦋 ARGUMENTS 🦋

• ha — HA context. that's your hardware hangout spot, the context it all happens in 🫶
• nv_cmd — NVRAM command. the actual instruction you're sending over there 💌

---

⭐ DESCRIPTION ⭐

alright so here are the bit definitions for the NVRAM command, laid out like the main character it is 👑

• Bit 26 = start bit
• Bit 25, 24 = opcode
• Bit 23-16 = address
• Bit 15-0 = write data

and what does it give you back? Returns the word read from nvram addr. that's the payoff, slay 💅
