bios_parser_...pectrum_info(9)

✨ NAME ✨

okay so this is the manual page for bios_parser_get_spread_spectrum_info, from the Kernel API Manual — page title energy: bios_parser_...pectrum_info(9).

The NAME line is literally bios_parser_get_spread_spectrum_info - and then... the description slot is empty. no invented summary, no cap 🫶

🦋 SYNOPSIS 🦋

here's the exact signature, bestie, formatting and all:

enum bp_result bios_parser_get_spread_spectrum_info (struct dc_bios *dcb
       , enum as_signal_type signal , uint32_t index , struct
       spread_spectrum_info *ss_info );

🎀 ARGUMENTS 🎀

• dcb — pointer to the DC BIOS.
• signal — ASSignalType to be converted to info index.
• index — number of entries that match the converted info index.
• ss_info — sprectrum information structure,

yes, the page spells it sprectrum, and yes, we are keeping that spelling exactly 💅

🌈 DESCRIPTION 🌈

okay so this function gets spread spectrum information from the ASIC_InternalSS_Info(ver 2.1 or ver 3.1) table or from the SS_Info table from the VBIOS. iconic.

Lowkey important: currently ASIC_InternalSS_Info ver 2.1 can co-exist with the SS_Info table. fr fr.

Expect ASIC_InternalSS_Info ver 3.1, there is only one entry for each signal /ss id. the way that's the rule, periodt. ✨

However — and this is the main-character caveat — there is no planning of supporting multiple spread Sprectrum entry for EverGreen 😭. that's the whole warning, bestie, don't shoot the messenger.

💜 RETURN 💜

Bios parser result code — that's it, that's the return. ✨

and that's the page, bestie! the footer says source/version ./drivers/gpu/drm/amd/display/..., date October 2026, and page bios_parser_...pectrum_info(9). bye bestie, mwah 💋
