get_ss_entry_number(9)

✨ get_ss_entry_number(9) ✨

okay so bestie, we're in the Kernel API Manual today and this one's a little function that goes and asks the VBIOS for its spread spectrum receipts 💅

---

🌸 NAME 🌸

get_ss_entry_number — (yes the description is literally blank in the OG, it's giving mysterious main character energy 🙈)

---

🎀 SYNOPSIS 🎀

uint32_t get_ss_entry_number (struct bios_parser *bp , uint32_t id );

---

💖 ARGUMENTS 💖

• bp — pointer to the BIOS parser. your little handle on all the bios-parsing goodness 🫶
• id — spread sprectrum info index (that's how it's spelled in the source, don't @ me 💀). it's the index you're asking about ✨

---

🦋 DESCRIPTION 🦋

so what it actually does: it gets the spread sprectrum information from the ASIC_InternalSS_Info Ver 2.1 table, or from the SS_Info table from the VBIOS 🔥

and here's the little rule you gotta remember — there can not be more than 1 entry for ASIC_InternalSS_Info Ver 2.1 or SS_Info. one entry, that's it, periodt 👑

---

🌈 RETURN 🌈

Bios parser result code 💫 (yep, that's the return value, that's the vibe)

💀 friendly heads up: those _v2_1 and _V2_1 spellings are not the same thing, so copy them character for character and don't get cute with the casing, okay? mwah 🫶
