💅 get_ss_info_from_internal_ss_info_tbl_V2_1 — the Kernel API Manual glow-up ✨

okay so bestie, welcome to the <pink>Kernel API Manual</pink> page for get_ss_info_from_internal_ss_info_tbl_V2_1(9) — yes that's the whole name, she's long, she's iconic, and the running header shortens her to get_ss_info_...nfo_tbl_V2_1(9) because honestly? same. 💖

---

✨ NAME ✨

get_ss_info_from_internal_ss_info_tbl_V2_1 — literally the function that pulls spread spectrum info out of the internal table, version 2.1 edition 🎀

---

🌸 SYNOPSIS 🌸

enum bp_result get_ss_info_from_internal_ss_info_tbl_V2_1 (struct
bios_parser *bp , uint32_t id , struct spread_spectrum_info *info );

like, three args, one return, no drama 🦋

---

🫶 ARGUMENTS 🫶

• bp — pointer to the Bios parser. your main character struct, she's doing the parsing 💅
• id — spread sprectrum info index. which entry you're asking for, iykyk 🔥
• info — sprectrum information structure. this is where the good stuff gets dropped off 🎀

---

👑 DESCRIPTION 👑

okay so here's the tea: this function gets the spread sprectrum information from the ASIC_InternalSS_Info table Ver 2.1, straight out of the VBIOS. 🧚

and here's the lowkey important bit: for Ver 2.1 there will not be multiple entry. one entry, that's it, periodt. 💀

---

⭐ RETURN ⭐

returns a Bios parser result code — enum bp_result, so go check what she gave you before you do anything unhinged with it 🙈

ngl, if you're deep in bios_parser.c at 2am, hydrate, stretch, and remember: one entry only for Ver 2.1. don't go looking for a second one, she doesn't exist 😭
