STRUCT OPTEE_RNG_PRIVATE(9)

💖 struct optee_rng_private(9) 💖

okay so bestie, welcome to the Kernel API Manual ✨ — this is literally the page for struct optee_rng_private, no cap. it's the OP-TEE Random Number Generator private data struct, and honestly? she's giving backstage-pass energy 🎀

🌸 NAME 🌸

struct optee_rng_private — OP-TEE Random Number Generator private data 🎲💅

like, the lil' bundle of secrets the OP-TEE RNG keeps to itself. icon behavior.

---

✨ SYNOPSIS ✨

struct optee_rng_private {
    struct device *dev;
    struct tee_context *ctx;
    u32 session_id;
    u32 data_rate;
    struct tee_shm *entropy_shm_pool;
    struct hwrng optee_rng;
 };

that's the whole struct, copied exactly, not one character out of place 🫶 read it, love it, respect it.

🦋 Members 🦋

• dev — the OP-TEE based RNG device. it's the device, she's THE device 💁‍♀️
• ctx — the OP-TEE context handler. handles the context, as handlers do 😌
• session_id — the RNG TA session identifier. it's a u32, it's the session's whole ID, it's iconic 🔥
• data_rate — the RNG data rate. u32 again. that's the rate at which the data does its data thing 🌈
• entropy_shm_pool — the memory pool shared with the RNG device. shared! with the device! teamwork makes the dream work 🫶✨
• optee_rng — the OP-TEE RNG driver structure. the driver structure, for the RNG, from OP-TEE. we love a self-explanatory name 👑

🎀 SEE ALSO 🎀

lowkey a reminder: every member above is listed exactly as the kernel headers list them, so if you're writing code against this, don't get creative with the field names, fr fr 💀
