STRUCT UEFI_CNV_VAR_WGDS(9)

🌸 NAME 🌸

struct uefi_cnv_var_wgds — WGDS table as defined in UEFI. Yep, that’s the whole name, and this is the Kernel API Manual page for it, bestie. 🫶

✨ SYNOPSIS ✨

struct uefi_cnv_var_wgds {
    u8 revision;
    u8 num_profiles;
    u8 vals[];
};

💅 Members 💅

Okay so this struct is giving “compact UEFI table” energy, and here’s every member:

• revision — the revision of the table. Literally just which rev we’re on. 💅
• num_profiles — the number of geo profiles we have in the table. The first 3 are mandatory, and can have up to 8. So yeah, 3 minimum, 8 maximum — no cap on the table’s cuteness, but there is a cap here. ✨
• vals — a per-profile table of the offsets to add to SAR values. This is an array of profiles, each profile is an array of struct iwl_geo_profile_band, one for each subband. There are UEFI_GEO_NUM_BANDS_REV3 or UEFI_GEO_NUM_BANDS_REV4 subbands depending on the revision. Not me getting all up in the subband math, but it’s giving per-profile offsets and we love that for us. 🌈
