STRUCT UEFI_CNV_VAR_EWRD(9)

💅 struct uefi_cnv_var_ewrd(9) ✨

okay so bestie, welcome to the Kernel API Manual — this is the page for struct uefi_cnv_var_ewrd, and it's literally the EWRD table as defined in UEFI. that's it, that's the vibe. no cap. 🫶

---

🌸 NAME 🌸

struct uefi_cnv_var_ewrd — the EWRD table, exactly as defined in UEFI. iconic behavior only. 👑

---

🦋 SYNOPSIS 🦋

here's the whole struct, copy it exactly please, she's fragile:

struct uefi_cnv_var_ewrd {
    u8 revision;
    u32 mode;
    u32 num_profiles;
    u8 vals[];
 };

---

✨ DESCRIPTION ✨

ngl the description on this one is really just "the members", so let's get into the members. this is where the plot is. 🍓

🎀 Members 🎀

• revision — the revision of the table. yes queen, tell us what generation we're in. 💅
• mode — this one is whether WRDS is enabled or disabled. (the page literally spells it "enbaled/disabled" and honestly? mood. we keep it. 😭)
• num_profiles — how many additional profiles we have in this table, and the range is (0-3). so like, zero to three extra profiles, that's the whole range, no more, no less. 🙈
• vals — the additional SAR profiles (#2-#4) as an array of SAR profiles. and bestie, a SAR profile is defined by the struct uefi_cnv_var_wrds::vals. the size of each profile depends on the number of subbands, and the number of subbands depends on the revision. this is all explained over in struct uefi_cnv_var_wrds. so if you're confused, that's where the lore lives. 📖✨

💀 one tiny thing: the source path in the footer is truncated in the original (./drivers/net/wireless/intel/i...), so don't come for me, i'm just relaying it faithfully. periodt.

and that's the page! sourced from ./drivers/net/wireless/intel/i..., dated October 2026, and the whole thing is filed under struct uefi_cnv_var_ewrd(9). mwah, slay, go read your kernel headers bestie 💖🧚⭐
