STRUCT IWL_PRPH_SCRATCH_VERSION(9)

💅 NAME 💅

struct iwl_prph_scratch_version — bestie, this is the version structure, periodt ✨

So like, welcome to the Kernel API Manual, which is the manual name btw, and this whole page is about one little struct that tells the firmware what version of the peripheral scratch thingy it's looking at. It's giving "tiny but important" energy fr fr 🎀

🌸 SYNOPSIS 🌸

struct iwl_prph_scratch_version {
    __le16 mac_id;
    __le16 version;
    __le16 size;
    __le16 reserved;
 };

Like, that's literally the whole thing. Four __le16 fields. Small, iconic, does its job 💖

✨ Members ✨

• mac_id — the SKU and revision id, iykyk 👑
• version — the prph scratch information version id, which is literally how you know which version of the info you're dealing with 🦋
• size — the size of the context information, measured in DWs (yes, DWs, that's the unit, don't @ me) 🎀
• reserved — reserved. That's it. That's the whole description. Leave it alone bestie 🙈

Obsessed with how many friends this struct has, ngl. It lives in the kernel file ./drivers/net/wireless/intel/iwlwifi/pcie/iwl-context-info-v2.h, and it's hanging out with:

• enum iwl_prph_scratch_mtr_format(9)
• enum iwl_prph_scratch_flags(9)
• enum iwl_prph_scratch_ext_flags(9)
• struct iwl_prph_scratch_control(9)
• struct iwl_prph_scratch_pnvm_cfg(9)
• struct iwl_prph_scratch_mem_desc_addr_array(9)

Like, the whole squad is here. Go read them all, no cap 💜

🌈 And that's the page! It came from ./drivers/net/wireless/intel/i... and it's dated October 2026, and it will forever be known as struct iwl_...atch_version(9). Slay. Byeee 💅✨
