qla2x00_get_fcode_version(9)

💅 qla2x00_get_fcode_version(9)

okay so this is a page from the Kernel API Manual — yes bestie, the kernel has lore too 🫶 — and it's all about qla2x00_get_fcode_version(9), which is a whole little detective story in ./drivers/scsi/qla2xxx. buckle up 🌸

---

✨ NAME ✨

qla2x00_get_fcode_version — literally just figures out what version an FCODE image is rockin' 💖

---

🦋 SYNOPSIS 🦋

void qla2x00_get_fcode_version (struct qla_hw_data *ha , uint32_t pcids
);

that's it. two args. no return type energy (it's void, we love a low-maintenance icon) ✨

---

🎀 ARGUMENTS 🎀

• ha — the HA context. your whole hardware vibe, handed over 💅
• pcids — a pointer to the FCODE PCI data structure. yes, a pointer. keep up 🫶

---

🌈 DESCRIPTION 🌈

okay so here's the thing. the process of retrieving the FCODE version info is, and I quote, "at best described as interesting." and honestly? that's the most diplomatic way anyone has ever said "this is a mess" 😭 iconic behavior fr fr.

here's the situation 👑:

within the first 100h bytes of the image, there's an ASCII string hanging out. and this string is packing several pieces of info — including the FCODE version. cute, right? WRONG. 💀

because apparently the only reliable way to actually get the version is by scanning for another sentinel within the string — the FCODE build date. so you're not even looking for the version, you're looking for the date to find the version. it's giving "find the side character to locate the main character" 🧚

and the thing you're scanning for looks like this:

... 2.00.02 10/17/02 ...

so yeah. you sniff out that build-date-looking pattern and the version comes along with it. sneaky but slay ✨

returns QLA_SUCCESS on successful retrieval of version. keep that in mind for your vibe check 💖
