get_ss_info_from_tbl(9)

💅 get_ss_info_from_tbl(9)

okay so you're in the Kernel API Manual bestie, welcome, this is the get_ss_info_from_tbl(9) page and it's literally all about pulling spread spectrum info out of a table 🎀

---

✨ NAME ✨

get_ss_info_from_tbl —

and that's it. that's the description. the man page really said "no thoughts, head empty" 💀 the name is there, the blurb is not. we move.

---

🦋 SYNOPSIS 🦋

enum bp_result get_ss_info_from_tbl (struct bios_parser *bp , uint32_t
id , struct spread_spectrum_info *ss_info );

look at her. she takes three things and returns an enum bp_result. slay 💅

---

🌸 ARGUMENTS 🌸

• bp — pointer to the BIOS parser. that's your parser babe, hand her over 🫶
• id — spread sprectrum info index. yes, "sprectrum". not me spelling it like that, that's straight from the source, iykyk 😭 it's the index of the spread spectrum info you want
• ss_info — sprectrum information structure. the struct where the info lands. again with the sprectrum. we respect the lore ✨

---

💖 DESCRIPTION 💖

so what does she actually do? she gets spread sprectrum information from the ASIC_InternalSS_Info Ver 2.1 table, or the SS_Info table, out of the VBIOS. lowkey iconic behavior 🌈

and here's the tea, the important bit, do NOT skip this:

there can not be more than 1 entry for ASIC_InternalSS_Info Ver 2.1 or SS_Info. one. singular. that's the rule, periodt 👑

---

⭐ RETURN ⭐

returns a BIOS parser result code. that's it, that's the whole return section, she's brief and she knows it 💜
