STRUCT UEFI_CNV_VAR_WRDS(9)

🦋 NAME

struct uefi_cnv_var_wrds — bestie, this is the WRDS table, exactly as UEFI defines it ✨

🌈 SYNOPSIS

struct uefi_cnv_var_wrds {
    u8 revision;
    u32 mode;
    u8 vals[];
};

Like... that's the whole vibe of it. Three fields. Iconic behaviour, no notes 💅

💖 Members

• revision — the revision of the table. Which one is it? Revision check, always 🔍
• mode — this is where WRDS is enabled / disabled. On or off, that's the whole personality 🎀
• vals — the values for sar profile #1, stored as an array 🫶 and the indexing is the main character here, so listen up:

vals[chain * num_of_subbands + subband]

that exact expression is what returns the right value, no cap. And num_of_subbands depends on the revision, so like... check your revision before you go indexing anywhere 😭 — for revision 3 it's UEFI_SAR_SUB_BANDS_NUM_REV3, and for earlier revisions it's UEFI_SAR_SUB_BANDS_NUM_REV2. Also the max number of chains is currently 2, so don't get creative 🚨
