STRUCT OPTEE_RTC(9)

💖 struct optee_rtc — OP-TEE RTC private data 💖

okay so bestie, welcome to the Kernel API Manual, and buckle up because we're about to vibe check a struct 🦋

---

✨ NAME ✨

struct optee_rtc — the private data for the OP-TEE RTC, no cap 👑

---

🌸 SYNOPSIS 🌸

struct optee_rtc {
    struct device *dev;
    struct tee_context *ctx;
    u32 session_id;
    u32 session2_id;
    struct tee_shm *shm;
    u64 features;
    struct task_struct *alarm_task;
    struct rtc_device *rtc;
 };

like, that's the whole thing. she's compact, she's iconic, she's giving main character energy 💅

🎀 Members 🎀

• dev — the OP-TEE based RTC device. literally the device itself, the whole reason we're here 🫶
• ctx — the OP-TEE context handler. the handler of the OP-TEE context, fr fr ✨
• session_id — the RTC TA session identifier. this is the TA session ID for the RTC 👑
• session2_id — the RTC wait alarm session identifier. a second session ID, specifically for the RTC wait alarm 🦋
• shm — the memory pool shared with the RTC device. shared memory, shared vibes 🌈
• features — bitfield of RTC features. it's a bitfield. of features. we love a bitfield 💜
• alarm_task — the RTC wait alamr task. (that's "alarm," she just typed it like that and honestly? iconic 😭) the task for the RTC wait alarm 🍓
• rtc — the RTC device. yes, again, but this one's the struct rtc_device *. the icon herself ⭐

ngl, some of these descriptions are doing the absolute bare minimum and honestly, same. but every single member is listed, so nothing got left on read 💀
