STRUCT UEFI_CNV_VAR_PPAG(9)

💅 struct uefi_cnv_var_ppag(9) — like, the PPAG table bestie 💅

okay so this is a page from the Kernel API Manual and it's all about one lil struct, struct uefi_cnv_var_ppag — the PPAG table as defined in UEFI. yes ma'am, straight out of the kernel, no cap 🫶

✨ NAME ✨

struct uefi_cnv_var_ppag — the PPAG table as defined in UEFI. that's it, that's the whole vibe 🎀

---

🌸 SYNOPSIS 🌸

here's the whole fit, look at her:

struct uefi_cnv_var_ppag {
    u8 revision;
    u32 ppag_modes;
    s8 vals[];
};

three members, zero drama. iconique 💅

🦋 Members 🦋

so let's meet the cast, one by one, main character energy only:

• revision — literally the revision of the table. that's her whole job bestie 💖
• ppag_modes — these are values from enum iwl_ppag_flags. yep, that enum, you know the one ✨
• vals — the PPAG values per chain and band, chillin' there as an array. and the way it works is vals[chain * num_of_subbands + subband] will return the right value 🎯 (iykyk). and num_of_subbands depends on the revision — for revision 5 it's UEFI_PPAG_SUB_BANDS_NUM_REV5, and for earlier revision it's UEFI_PPAG_SUB_BANDS_NUM_REV4. also the max number of chains is currently 2, okay? just two. that's the whole roster 🧚

go look at the Kernel file ./drivers/net/wireless/intel/iwlwifi/fw/uefi.h — that's the home base bestie 🏠 and while you're there, the whole friend group is:

ok that's the whole page, go read the other twelve or whatever 🙈

and finally, the cute lil sign-off: this came from ./drivers/net/wireless/intel/i... and it's dated October 2026, and the header/footer both say struct uefi_cnv_var_ppag(9) — periodt 💜🌈
