STRUCT OPTEE_REVISION(9)

✨ struct optee_revision — OP-TEE OS revision reported by secure world ✨

okay bestie, welcome to the struct optee_revision(9) page 💖 this is a Kernel API Manual situation, and honestly? it's a lil cutie. it's the struct that holds the trusted OS revision that secure world hands over to you. let's get into it 🫶

🌸 SYNOPSIS 🌸

struct optee_revision {
    u32 os_major;
    u32 os_minor;
    u64 os_build_id;
 };

like, that's the whole thing. three fields. iconic minimalism, no cap 💅

🎀 Members 🎀

• os_major — the OP-TEE OS major version. the big number energy 👑
• os_minor — the OP-TEE OS minor version. the lil garnish on top 🍓
• os_build_id — the OP-TEE OS build identifier, and it's 0 if it's unspecified. so if you see a zero, that's not a bug, that's just "unspecified" being unspecified 🙈

🦋 Description 🦋

so where do these values even come from? they come from OPTEE_SMC_CALL_GET_OS_REVISION (that's the SMC ABI route) or OPTEE_FFA_GET_OS_VERSION (that's the FF-A ABI route). pick your lane, either way the revision shows up 🌈

⚠️ read this twice bestie: this is the trusted OS revision, not an FF-A ABI version. do not confuse them. i'm literally begging 😭
