STRUCT QSEE_REQ_UEFI_SET_VARIABLE(9)

🎀 struct qsee_req_uefi_set_variable(9) 🎀

okay bestie, welcome to the Kernel API Manual 💖 you're literally about to meet struct qsee_req_uefi_set_variable — the request struct for the SetVariable command. yes that's its whole vibe. let's get into it ✨

---

✨ NAME ✨

struct qsee_req_uefi_set_variable — literally the Request for the SetVariable command. that's it, that's the name, no cap 🫶

---

🌸 SYNOPSIS 🌸

struct qsee_req_uefi_set_variable {
    u32 command_id;
    u32 length;
    u32 name_offset;
    u32 name_size;
    u32 guid_offset;
    u32 guid_size;
    u32 attributes;
    u32 data_offset;
    u32 data_size;
 };

look at her. nine u32 fields. main character energy fr fr 👑

🦋 Members 🦋

okay so here's the member-by-member breakdown, iykyk:

• command_id — the ID of the command. it must be QSEE_CMD_UEFI_SET_VARIABLE. like, non-negotiable, periodt 💅
• length — length of the request in bytes. and bestie, that includes this struct and any parameters (name, GUID, data) stored after it, plus any padding thereof required for alignment. it's giving "everything counts" 😭
• name_offset — offset from the start of this struct to where the variable name is stored, in bytes. and the name is stored as utf-16 string, so heads up 🌸
• name_size — size of the name parameter in bytes, including null-terminator. don't forget the null-terminator, bestie, it's lowkey important 🙈
• guid_offset — offset from the start of this struct to where the GUID parameter is stored, in bytes. yes, more offsets. we love a coordinate system 🔥
• guid_size — size of the GUID parameter in bytes, i.e. sizeof(efi_guid_t). iconic, exact, no guessing ⭐
• attributes — the EFI variable attributes to set for this variable. you're setting the vibes of this variable, literally 💜
• data_offset — offset from the start of this struct to where the EFI variable data is stored, in bytes. third offset, third slay 🎀
• data_size — size of EFI variable data, in bytes. that's how much actual data you're carrying, ngl 🍓
